IRONTECH BES SETUP

July 12th, 2010

Often times at IronTech, we get calls from clients who want to install a new BlackBerry Enterprise Server or Blackberry Professional Software Express (the free version of BES) at their company. Surprisingly, a lot of people run into trouble installing a BES server because of the many steps and prerequisites you have to go through. You really need to have experience installing and troubleshooting a BES extensively to have a fast successful deployment. I have written this Blackberry Server Install Guide to help anyone install a BES successfully. If you run into any issues, email us at info@irontechsolutions.com

BES Install Prerequisites:

-Set aside between 45 minutes to 2 hours to allow yourself time to install all pre-reqs and then install and configure the BES server. You will need to reboot the server so make sure you have scheduled downtime on the server.

-Verify you have the correct Blackberry server software, Licenses, and SRP identifier. If not, call RIM.

-Verify that you are not blocking outbound ports in your organization. If you are, you need to make sure TCP port 3101 is allowed outbound from the server you intend to install the BES on. Your BES will communicate to RIM’s servers using this port. YOU DO NOT need to allow port 3101 inbound to your server.

-Verify that your Exchange Server has SP2 (Service Pack 2) applied.

-If you are installing BES on a member server (which is the best pratice), make sure Exchange System Manager has been installed on it.

-Make sure Outlook is not installed on the same server as the BES. A lot of small businesses with SBS 2003 install Outlook on the server. Uninstall it if you plan to install a BES on an SBS server.

-Install the latest Microsoft Data Access Components (MDAC) from Microsoft:

http://msdn2.microsoft.com/en-us/data/aa937730.aspx

-If you have already installed your SQL server, make sure the BESAdmin account has Server Administrator and Database Creator permission to the database instance.

-Make sure your spam firewall has white listed emails from *.blackberry.net. Working at IronTech, I have seen over aggressive spam firewalls blocking emails required for Enterprise Activation because of .dat attachments in the message.

-Optional: Verify TCP port 4101 is allowed to communicate outbound. This port is used by Blackberry Desktop Manager to do a serial bypass for least cost routing. It is not necessary to open this port unless you need this feature.

Now onto the actual install!

1. Login to your server using a Domain Admin account and create a new user called BESAdmin (and make sure you create a mailbox when you create the account). DO NOT ever use the default Administrator account with a BES. You must create a service account.

2. Verify the BESAdmin user is part of the Domain Users group only. It is not necessary to give the account Domain Admin privileges since we are going to give the account local login access in the next steps but you can give it DA access if you want. It’s best practice to leave the account as a Domain User because you always want to give an account just enough permissions to perform it’s function. Also you have to go back and check Send As/Receive As rights if you give it DA access because they are usually set to deny.

3. Now make the BESAdmin a local admin on the server.

On a Domain Controller or SBS server – This is done in AD via the “Built-in Administrators” group
On a member server – This is done by right mouse clicking My Computer and selecting Manage. From Computer Management expand “Local Users & Groups” and select Groups. From Groups double click “Administrators” and add the BESAdmin account.

4. Now give BESAdmin local rights:

On a Domain Controller or SBS server – “Domain Controller Security Policy” and expand the “Local Policies” and “User Right Assignment”. You need to add BESAdmin to “Log on Locally” and “log on as Service”.
On a member server – “Local Security Policy” and expand the “Local Policies” and “User Right Assignment”. You need to add BESAdmin to “Log on Locally” and “Log on as Service”.

5. Open up Exchange System Manager (ESM) and right click the root “YourDomain (Exchange)”. Click on Delegate Control and add the BESAdmin account as an Exchange View Only Administrator.

6. Drill down in Exchange System Manager until you get to your server name. Right click on the server name and hit properties. Now click the Security tab. Add the BESAdmin account and the following permissions:

a. Administer information store
b. Receive As
c. Send As

7. Open up Active Directory and in the top Menu bar, select “View” and then click on “Advanced Features”. Now go to each user you want to add to the BES server and double click on them. Go to the “Security” tab and add the BESAdmin user. Give the BESAdmin account “Send As’ rights.

8. Logout of the server. Now log back in as the BESAdmin user. Now you can begin the BES server installation. You want to select the “Blackberry Enterprise Server” option. Just double-click on the executable and go through the wizard. Accept all agreements and begin the install. Half way through, it will tell you to reboot. Once the server reboots, you can log back in as the BESAdmin and the installer will automatically start back up and continue the install.

9. Once you get to the database portion of the install, make sure to leave the default name of “BESMgmt” as the database name. You may need to create a new SQL instance for the BES server if you already have other names SQL instances running. Do not put it under once of these are instances. The BES server should run under it’s own SQL instance if at all possible.

10. When you get to the screen to enter the license, just copy and paste it exactly as RIM gave you. Then copy and paste the SRP identifier and SRP authentication key and make sure to Test your connection. If you cannot connect, verify TCP port 3101 is allowed to connect outbound. A simple test is to open a command prompt and type:

telnet srp.us.blackberry.net 3101

If your command prompt goes to a black screen, then you are able to connect.

11. Once the install is done, open up Blackberry Manager. You will get an error saying no MAPI profile has been chosen. Hit okay and type in the name of your server and choose the “BESAdmin” account. Hit “Check Name” and then press OK.

12. Now Blackberry Manager will open up. On the right hand side, you should see that the SRP status is “Connected”. If it is not connected, wait a few minutes and then refresh.

13. Once you verify you have an SRP connection, you can begin adding users. I prefer to use Wireless activation for all handhelds. Just user the Add User wizard in the left hand column to add the user.

14. The user will get an email in his mailbox. Just have the user open Outlook and verify the email has been received from BESAdmin and contains an activation password. The user just needs to go to Enterprise Activation on his/her handheld and type in their email address and this password to activate their account on their handheld. It can take anywhere up to 5 minutes or more to complete an activation depending on the user’s mailbox and speed of connection to their provider’s data network.

NOTE: If the user was using BIS, you may need to wipe the handheld before doing an Enterprise Activation with your new BES server. Otherwise the BIS service books will cause activation to fail.

Always make sure that the date and time are set correctly, the time zone is set to the correct time zone (handhelds default to Casablanca usually), and that the top write corner of the handheld says “EDGE”, “GPRS”, or “3G” in call capital letters and not lowercase.

15. The handheld will tell you when Enterprise Activation is complete. On a new activation (as in this is the first time that particular phone has been added to the BES), it will pull down 14 days worth of email onto the phone. If you had previously had the phone on the BES and you removed it and are reading it, it will not pull down all your old email. Just keep this in mind when doing Enterprise Activations.

Additional Notes:

-If the user you are adding to the BES is a Domain Admin, you can get them on the BES and their handheld will work for a little while but then it will stop sending email after about an hour. I have seen this happen time and time again working at IronTech when we “inherit” a BES server at a new client. This is because your Send As permission for Domain Admins will revert on the Exchange server unless you explicitly edit the ACL to allow for it. Run the following script from a command prompt using the DsAcls tool on your server after installing Windows Server 2003 Support Tools (http://technet.microsoft.com/en-us/library/cc755938.aspx):

dsacls “cn=adminsdholder,cn=system,dc=domainname,dc=com ” /G “YourDomainName\BESAdmin:CA;Send As”

Fore more info on this, view KB 907434 from Microsoft at http://support.microsoft.com/kb/907434

-If you are having trouble activating a device wirelessly, your BES server has tools on it to help your troubleshoot. Run the following tool to test for connectivity:

C:\Program Files\Research In Motion BlackBerry Enterprise Server\Utility\BBSrpTest.exe

-By default, a user’s deletions on his/her handheld are not synched with Outlook. You either have to set the reconciliation on the handheld or you can set it for all users on the Blackberry server itself. RIM has it set this way by default so users don’t accidentally delete important emails on their handhelds. I never change the default unless the user specifically requests it and I only change it on the Blackberry server itself if the point of contact at the organization approves it.

-Blackberry Professional Software Express (aka BPS, BPSE, replacement for BES Express) does not support HTML rendering yet. Only full blown BES supports it starting with SP6 which was released last year. HTML rendering is a pretty new feature so it will eventually trickle down to Professional. Just make sure the user’s phone is running OS version 4.5 and when they release the SP, it should work just fine.

If you ever run into any issues with your Blackberry Enterprise Server and need some help, just email us at info@irontechsolutions.com.

Ways To Promote Your Website

July 12th, 2010

You have created your own web site (an on line store for example)!
Customers can choose goods, pay for the goods and they will be delivered to the customer’s palce. But! Customers must know about your on line store and visit its web site, so you need advertising. How to promote an on line store? Every on line trader asks himself/herself this question sooner or later. Let’s try to overview some ways of promoting web sites.

Banner advertising.
Sometimes it seems that banners appeared at the same time with the net. Banners is the most widespread kind of advertisement in Internet. What is a banner? A banner is a graphic block of a certain size (468х60, 100х100, 125х125), that bears advertising information. Banners are mostly displayed with the help of banners nets. A banner net allow you to display your banners on the sites of other owners displaying others banners on your own web site. The banner net usually takes a commission percent. But as your site is “young” enough the amount of displaying banners on yoru site won’t be large too. That’s why you will have to buy banners displays at one of the nets.

You should also pay attention to the creation of a banner. As what is a banner on its essence? A banner is very close to a announcement in a newspaper, that’s why a banner must arrest people’s attention at once. Modern Internet technologies allow you to create “live” banners that can forward you to the necessary part of the site or to add sound to your banner. Besides the statistician says that users click more often on banners with animation than on static banners, and of course banners along with the site must be very stylish. In Internet you can find a lot of good pieces of advice how to create banners. Or you can pay money to specialists and they will create banners for your on line business.

There is one more way to promote your web site. These are mailing lists.
Mailing lists have their own advantages over banners.
The first — users sign up for a mailing list on their own will, so there is a big possibility that your mailing list will be read (this can be compared with subscriptions to newspapers)
The second — you can display hidden advertisement in a mailing list in kind of stories about new goods for example (with the link to the goods), field of view of your on line store etc.
The third — in your mailing list you can display banners of any sizes whatever you want.

You also must remember that the information is sent to a user only if the user wants to get this information (when he/she signs up to the mailing list). Do not overload the user with the information otherwise the user will refuse from your mailing lists. If your site offers a wide range of goods. allow your users to choose the category of goods he wants to get information about.

You also shouldn’t forget that many people use Internet for communication. So, visit different forums and chats and leave the address of your store there. Visit all free notice boards and display the information about your store there too.

These days the online technologies have become very popular. The web network is not only a place to entertain but also a space to make money. Whatever the reason is, to be presented in the Internet one needs a site. And it is the time when the question how to plan a website arises. Those who are searching for details on how to build a website, should refer to the Internet itself. There are lots of tutorials on how to plan a website and related topics.

In any way, it wouldn’t be wise not to avail themselves of this opportunity given to us by modern technologies. Google and other search engines, social networks and forums, blogs – all of them could assist to find information on “business plan for website” and similar topics.

Hurricane Season- Are You Ready

June 30th, 2010

So Alex is now passing through and everything seems to be ok but what if it hadn’t turned.  Would your company be ready to act and have everything failed over to your stand by site or would you be running around trying to figure out what to do.  Hurricane season in the south is always exciting for us as we try to get our clients to prepare for possible disasters.  I cant stress enough how important a disaster plan is to businesses not just for hurricane season but being prepared for any disaster.  Below is a basic outline to help let you know if you are ready.  These are the steps the government recommends when preparing this season.

Assess your current plan. Conduct a business impact assessment that prioritizes critical processes for the entire organization. For example, processes that need to resume within 24 hours to prevent serious mission impact, such as essential citizen services, could receive an “A” rating.

Take steps to protect data. Agencies should back up data frequently to ensure that data integrity and applications are not jeopardized.  Agencies should also store multiple copies of data off site, at a remote location, a long distance from the primary data center.

Review power options. Agencies should add uninterrupted power supplies (UPS) to keep the most essential applications running.  In addition, cooling systems should be supported by backup generators. Temperature spikes can cause unplanned interruptions when operations are most critical.

Identify and appoint a cross-functional preparedness team. Create a team to design and test the disaster recovery plan, as well as a recovery team, which will participate in recovery activities after any declared disaster.

Document, test and update. The disaster preparedness plan should include logistical details, including travel to backup sites, and even who has spending authority for emergency needs.  The plan should be tested in an environment that simulates an actual emergency.

Consider telecommunications alternatives. Following Hurricane Katrina, many organizations lost access to reliable telecommunications equipment for days.  Alternative communications vehicles, including wireless phones and satellite phones, should be considered.

Form tight relationships with vendors. Hardware, software, network and service vendors can help expedite recovery, can often ensure priority replacement of telecommunications equipment, personal computers, servers, and network hardware in the event of a disaster.

How IT Managed Services Can Save Small Businesses

June 9th, 2010

How IT Managed Services Can Save Small Businesses

Scary times are upon us and the economy seems to be getting worse by the day. Small Businesses make up the backbone of America and many owners are wondering how they will survive. Cutting costs in every way they can and trying to plan everything can get hard and for most helps very little. Small Business doesn’t mean the same thing that it used to; in fact many small businesses conduct their business all over the world. Communication, computer and server function and reliability, and data disaster recovery are major factors in the success of the business world today.

Let’s talk now about IT and how people use it. Let’s say we go and examine a small accounting firm to see what they would use as far as technology. Well chances are you won’t walk in and see a bunch of people with adding machines and notebooks on their desk. What you will probably see is several desktop computers, a fax machine, and a few printers right? What about what programs are on those computers, we will probably see Microsoft Office (Word, Excel, and Outlook) as well as QuickBooks and maybe some other accounting programs. What about the company’s email, do they have their own email, or are they using a web based email client? How are the company’s files backed up in case of a disaster recovery, if they are even backed up at all? Does the company get their email on their phones? Does the company have their own website? What does a company do if they have a workstation that gets a virus? What if the employee who is currently taking care of a company’s workstations and servers is unable to repair the workstation, or they have a computer failure that causes the company to loose valuable data, and the employee just can’t recover it? Who can they call for help?

So what does all this mean? Well those programs need to be supported and so does what they connect to (servers, routers, and switches). So that means that you have to have someone around to keep them running. After all, if you lose a computer or server you might lose a lot of money also. There are many companies that have a single employee that can take care of certain issues concerning the maintenance of individual computers, and even simple server problems. However, this individual is very seldom a certified IT professional, and can not provide the same level of service or information that a certified IT professional is able to. There are often times where a company is not even aware of the potential of their equipment, email, or file sharing abilities. Or even, the security issues that unqualified personnel can create unknowingly.

Well for the past 5 or so years there has been a trend growing in the United States that is really saving SMB’s money while making them more efficient. The term used it called Managed Services which really means Outsourced IT. Companies such as IronTech Solutions provide companies with professional IT management, for less money than a company hiring it’s own IT department employees.

We also have to cover the companies who have no IT support and try to do it themselves. This is very dangerous considering what was mentioned above. To give you an example of what scenarios there are for these businesses let’s say we have a small mortgage company with an email server and a server that holds records for all of the mortgages they have given out over the years. One night the weather gets bad and lightning hits a power transformer outside causing the server to crash. The owner who thought he knew enough to maintain the network had never checked the backups or even tried to back any information up. So now he calls in a company to try to recover the data on the server and get email back up, they tell him they were able to get some of the records back but all of his email is lost. Where does he go now? How much did he lose and how will he recover the data? To get to the point here he probably would have to spend about 3000 dollars to recover as much of the data as he can, plus the down time while employees couldn’t work, not to mention the data he didn’t get back and now can’t.

The point here is that IT should be left to administrators who understand what needs to be done on a daily basis. Managed service companies could have prevented this disaster by having dedicated professionals that are constantly monitoring the environment for situations like this.

IronTech Solutions has the most experienced and highly trained personnel in the industry. IronTech employs personnel that can handle any IT situation from remote care and maintenance of individual workstations and software, all the way to company network design and implementation. Whether your company has an established IT department and is in need of consulting, or if your company is in need of IT monitoring and establishment, Irontech solutions can help your company become up to date in the technology of today, and keep your company current with software and technological advances in the future.

Infrastructure Optimization: IronTech’s roadmap from a Reactive to Proactive IT environment

January 28th, 2009

Your IT infrastructure can be more than just a service – it can be a crucial strategic asset to your organization. Microsoft developed the Infrastructure Optimization Model (IOM) as a gauge for organizations and provides a logical roadmap to progress from reactive to proactive IT service management that IronTech provides to businesses all over Houston and Dallas.

 

What category does your IT currently fit in?

 

  • Basic – You’re fighting fires
  • Standardized- You’re gaining control
  • Rationalized – You’re enabling your business
  • Dynamic – Your IT infrastructure is a strategic asset

 

Most of our clients come to us somewhere between a Basic or Standardized infrastructure level. This is what IronTech likes to refer to as a “Reactive” state. At the Basic level, the company is either has a server (or needs one) but all PCs are still on a workgroup rather than a domain. They is no IT policy in place and each machine is managed locally by the user. There is no Active Directory (central management). At the Standardized level, the company has at least one server and all computers on the network are joined to the domain and using Exchange. Beyond that, there is not much standardization because there are no active IT policies in place to manage the environment. At some point in time, an IT guy setup the environment but since then it has never been managed or even backed up correctly. These companies have been fighting fires daily until they call us.

 

IronTech then takes these clients to the Rationalized level overnight. This is no exaggeration. Our certified technicians can typically resolve whatever issues or misconfigurations exist in a network within 8 hours (1 business day). Then we setup our proactive monitoring of disk space levels, event log monitors, CPU and page file monitors, daily spyware and virus scans, weekly disk defragmention, daily backup monitoring, and a number of other proactive measures on all servers, desktops, and laptops. Now the company is in a “Proactive” state because they are no longer fighting fires. Issues are no longer popping up every day that brings business to a halt. Whenever a user has an issue, an IronTech technician is just a phone call or trouble ticket away and can fix most issues that might crop up in an average of 45 minutes. This is a real figure based on our current ticket resolution rate for our clients.

 

Finally, our clients realize how important having a properly managed Proactive IT environment is and are elevated to the “Dynamic” level. Their company is fully aware of the strategic value their infrastructure provides in helping them run their business efficiently and staying ahead of competitors. It connects people, processes, and information in a way that drives results for the company. IronTech not only provides the support, but also the direction for the IT infrastructure of the company as it grows. This “Dynamic” level of IT is the ultimate goal for IronTech for all our clients.

 

Microsoft IOM Core

 

 

 

 

 

 

 

 

 

 

 

 

 There are 5 criteria that improve and evolve as a company reaches each level:

 

Identity & Access Management – The solutions in place that should be implemented to manage and protect identity data (synchronization, password management, and user provisioning, etc), and how to manage access to resources from corporate mobile users, customers, and partners outside of a firewall. An example IronTech always used to describe this is going from a workgroup environment to a domain environment using Active Directory technology built-in to Windows Server platforms such as Windows Server 2003, Windows Server 2008, Small Business Server, etc.

 

Desktop, Device, and Server Management – The solutions in place to manage desktops, mobile devices, and servers as well as how to deploy patches, operating systems, and applications across the network. This criteria also provides guidance on how you can leverage virtualization and branch office technologies to improve your IT infrastructure. IronTech’s managed services systems will provide this part of your IT infrastructure.

 

Security and Networking – The solutions implemented in your IT infrastructure to help guarantee that information and communication are protected from unauthorized access. These solutions have mechanisms to protect your IT infrastructure from denial attacks and viruses while preserving access to corporate resources. Believe it or not, IronTech has run across clients that were using consumer grade routers in their environment instead of business grade routers such as Cisco, Sonicwall, Checkpoint, Juniper, etc. and have helped migrate them to these business grade platforms for a robust network environment.

 

Data Protection and Recovery – The solutions in place to provide structured backup, storage, and restore management. As information and data stores proliferate, organizations are under increasing pressure to protect that information and provide cost-effective and time-efficient recovery when required. Clients at the Basic level sometimes do not even backup their environment. Standardized clients typically use single tape backup decvices coupled with industry proven software such as Symantec BackupExec. Clients that reach higher levels usually implement offsite tape backup rotations, image level backups, disk based backups, tape vault libraries, server or storage standby failover, or even system snapshots backed up offsite in 15 minute or greater intervals.

 

IT and Security Process – The processes in place to cost-effectively design, develop, operate, and support solutions while achieving high reliability, availability, and security. While rock-solid technology is necessary to meet demands for reliable, available, and highly secure IT services, technology alone is not sufficient; excellence in processes and people (skills, roles, and responsibilities) is also needed. This is an ongoing process that envelopes all other solutions above. Typically small businesses at the Basic level do not take into consideration or have the skill necessary to plan and implement these processes. When IronTech takes a client to the Rationalized level or higher, the role of creating these processes becomes a combination of IronTech and the people at the company working hand in hand to build the processes that ensure a secure, stable, and cost effective environment.

Outsourcing your IT in a recession economy

January 2nd, 2009

This past year has been very tough for our economy and as of Dec 1, we are officially in an economic recession (http://www.msnbc.msn.com/id/27999557).  The vast majority of industries in the US have felt the crunch this year.  Many long standing businesses in the US have gone bankrupt such as Circuit City, Linen & Things, Bennigans, Steak & Ale, and others.

 

Traditionally for many companies, the first costs to cut are usually in the IT budget as we all saw and experienced with the 2000 dot com bubble burst.  Many companies learned a valuable lesson from that and we saw a surge of IT outsourcing happen in those days.  Many companies outsourced their software development departments to India and China and the US economy saw a lot of unemployment in the software development industry.  Infrastructure support of course could not be outsourced for any company since you need engineers onsite to build and support your environment.  Back in those days, you only had the option to rely on your inhouse IT support people for this.  As a result, infrastructure support and systems administrators did not feel this kind of unemployment impact.  Unfortunately for businesses, this meant they had to ride out the costs of having inhouse IT support at a premium price.  Over the years, the managed services of infrastructure grew larger and companies like IronTech Solutions answered the call to help support these businesses that were looking to lower costs of IT across the board and not in such niche areas as software development.

 

These days, businesses are more and more dependent on their IT infrastructure than ever before and the impact of the recession on IT outsourcing worldwide has been no slowdown at all.  The outsourced IT industry in Houston and Dallas has seen no slowdown all year.  In fact, IronTech has been signing on new clients for managed services exponentially every month as more and more businesses realize the benefits of having an entire IT department supporting them at a fraction of the cost of hiring one fulltime onsite administrator.  IronTech has also steadily been increasing our staff augmentation services as well with some companies that have a fulltime admin on site, but just need an extra hand with the day to day support of the business both onsite and remotely. 

 

Most small & medium size businesses and their owners are feeling a credit and funding crunch right now.  The solution that most have found is to optimize resources and lower costs wherever possible.  This is where choosing managed services/outsourcing can lead to high profitability for a business because the costs are so low, even with 24/7 support such like IronTech provides.  Companies want to stay flexible and have a highly skilled workforce, while reducing capital expenditures.  Forrester Research says that managed services will see a marked increase for the next few years as more companies realize that benefit of outsourcing their IT according to a study released on Dec. 15, 2008.  Besides the macro economic forecasts, this is increase is lead by two factors:

 

Faster technology change – In the SMB world, think Microsoft Windows Server 2008, Small Business Server 2008, Exchange 2007, Sharepoint Services 3.0, Response Point, Hyper-V, VMware ESXi, etc.  These new technologies offer companies a blizzard of new capabilities without a big hit on their IT budgets.  In fact, these technologies all cut costs in an environment compared to their predecessors.  The companies that choose to invest in these new technologies will see a higher ROI as well since these technologies can lay a foundation in an environment that can upscale for years to come.  Additionally, managed services through IronTech can offer safeguards for all this change.  Do you really want to spend your IT budget in sending your existing IT to training or do you want certified experts in these technologies ready to work for you now?

 

We are on the verge of a technology investment cycle – Even with the economic uncertainty, Information Technology is on the verge of a huge investment cycle.  The IT industry typically operates in a cycle of innovation and growth followed by a cycle of refinement and digestion.  Forrester Research believes that 2009 through 2017 will be a period of innovation and growth unlike any previous cycles.

 

With the savings on capital expenditures, nimbleness of the network, certified skilled workforce, and ability for a business to focus on core business instead of IT, IronTech Solutions expects to see a period unprecedented growth in IT Outsourcing in Houston and Dallas in 2009.  As an award winning managed services provider, IronTech provides desktop support for all users and applications, 24/7/365 server monitoring and support, automated patching and security audits within an environment, server and application hosting in our state of the art Tier 4 data center, and CTO services to provide your company direction in infrastructure as your core business grows.  Our pay as you go business model allows small and medium size businesses to easily scale up or scale down based on the number of users at the company and what business needs have to be met.  All this is provided at a low monthly flat fee so there are no unexpected costs and a business has total control of their IT budget.

Server Virtualization for SMBs explained

December 13th, 2008

Server Virtualization refers to a complete operating system that runs in a guest virtual machine (VM) on the host operating system.  This host operating system is know as a “hypervisor” (such as VMware ESX, Microsoft Hyper-V Server 2008, and Citrix XenServer).  This guest VM is completely independent of the host operating system and can be moved from one server to another or even run on another hypervisor platform entirely if converted.  Since each guest VM is completely enscapsulated, you have the ability of running multiple VMs on one server.  The hypervisor which sits between the physical hardware and the guest VMs manages the shared resource allocation of the server.  This allows you to take advantage of the resources of a physical server that would otherwise sit idle.  When you tally up the cost of electricity, air conditioning, space, battery backups, etc., you will find that if your environment has many servers, the costs can get very high very quickly.  This is where server virtualization has it’s greatest benefit.  Add to this the flexibility of moving your server to another server on the fly in the event of a hardware failure of disaster scenario, virtualization goes from being a “cool trend” to a “must have” for many companies these days.

  

vmware_virtualization

 

ESX, Hyper-V Server 2008, and XenServer Enterprise are all “bare-metal hypervisors” which means they do not require an operating system installed on the server at the time of the hypervisor installation.  They are in essence their own OS.  You will notice however that ESX is based on Linux Redhat and Hyper-V is based on Server 2008 Core.

 

The other kind of hypervisor is the software hypervisor that requires a host OS already installed on the server or desktop to run.  Examples would be VMware Server, XenServer Standard, Hyper-V (the one that ships with Server 2008, not the baremetal version above that you have to download online).  The good thing about using a software hypervisor is that you don’t have to reformat an existing server to install a hypervisor.  You can continue using the existing server as you always have with the added benefit of having one or more virtual servers running right along side it.  The downside of using a software hypervisor package within a host OS is increased overhead. 

 

This is just the tip of the iceberg.  There are so many virtualization options available, which one is correct for small and medium size business?  Most SMBs typically enter the virtualization market for two reasons:

 

1. High availability of a server (such as a mail server, web server, etc.)
2. Total cost of ownership & ROI (the company realizes that buying yet another physical server is not cost effective)

 

The next question an SMB should ask is how much is it going to cost to virtualize and consolidate your servers?  Without going into too many details and comparisons of features, the typical small to mid size business can virtualize for free using a free hypervisor as long as your exisitng physical server will support it:

 

1. VMware Server – FREE
2. Hyper-V Server 2008 – FREE

 

While other hypervisor options include many different features, using VMware Server or Hyper-V Server 2008 are two ways an SMB can see what a hypervisor can do for them without the making a huge investment in buying Enterprise class software such as VMware ESX or XenServer Enterprise.

 

VMware Server should be considered the entry level hypervisor for SMBs.  This is absolutely free and will install on your existing Windows 2003 Server just like any other application.  The hardware requirements are flexible.  The only thing you have to worry about is having enough RAM available for your guest machines.  VMware Server cannot be used for high availability, you will have to purchase it’s bare-metal big brother ESX.  Using VMware Server is a great way to see how powerful virtualization can be in your environment first hand.  If you choose not to go the virtualization route for whatever reason, just uninstall it from your server just like any other application.

 

Hyper-V Server 2008 is a free download on Microsoft’s website.  One important point to note for Hyper-V is that since it is a bare-metal hypervisor, you cannot install it on an existing server without first formatting it.  The hardware requirements of Hyper-V also have to be met.  The biggest problem SMBs usually face is that their existing server is not 64 bit and the processor does not support hardware assisted virtualization (Intel VT or ADM-V).  Most SMBs will likely have to purchase a new server for this purpose since these hardware specs have only been in the market for just over a year now.  So for an SMB that wants to get a taste of actual bare metal virtualization at the cost of purchasing a new server, Hyper-V is an excellent choice.  The good news is that this is completely scalable.  If you want to purchase additional servers and setup multiple Hyper-V servers, you can basically “daisy chain” them all together and create a high availability solution.  If one physical server were to fail (let’s say a power supply goes out), it will Quick Migrate the servers to other physical servers as long as you have some kind of shared storage setup between all the servers.  Your users will never know something has happened since the migration is seamless.

 

In summary, there are many configurations and flavors of virtualization available these days.  The solution you need will depend on what requirements your business has and what the budget is.  IronTech consulants are certified virtualization specialists that can help you choose what’s best for your company on a variety of offerings from Microsoft, VMware, and Citrix.  We have virtualization demonstrations available in Houston and Dallas and can even give you a “loaner” server to virtualize some of your servers to show you how seamless yet powerful server virtualization can be.
