When it comes time to start thinking about Virtualization, here are 5 important factors to think about:

1. Platform: Which is the most Suitable Platform?

There really are only three major competitors: VMWare, Microsoft Hyper-V, and Parallels Virtuozzo. Each one of these platforms offers Competitive advantages as well as different pricing models.  For Example, running Microsoft Hyper-V allows you to run unlimited Windows Operating Systems under a single License which would lower the license costs for your organization, but might it may not be the best candidate if you are a Linux based organization. 

2. Number of Containers: How many virtual servers can you fit on each Server?

This really depends on the current CPU/RAM usage of your current environments.  One commonly made mistake is overloading the host server with too many Virtual Instances which will cause poor performance. 

3. Domain Controller Placement

Another thing to take into consideration is failover and proper disaster recovery for your Domain Controllers.  Placing your Primary and Secondary DNS server on Separate Virtual Nodes is best practice as well as having enough failover machines to handle the event of a Virtualization Host Failure. 

4. Migration Strategy

Determine a Migration Strategy and evaluate all your current candidate applications to migrate to your virtual environment.  Note that not all applications should be migrated to virtual environments.  For example, some versions of Microsoft Exchange are not supported on select Virtual Platforms.  Doing your homework  is one of the most important step that needs to be taken before moving to a new environment and/or platform.

5. Failover and Backup Plan

Now that you are running more environments on fewer servers, backup and disaster recovery become even more critical.  Setting up a proper backup strategy for all of your Virtual Environments is crucial.  On the disaster recovery side, even if you run your virtual servers in house, you should secure a failover Virtual environment.  At LogicalSolutions.net, we offer failover Virtual Environments that will run your applications in the event of a failure.

I have been in the data center services industry for about 10 years now and I never get tired of the question…..”which data center is right for me?”.  Well, as many of you know, the answer can be an endless list of marketing blah.  But the real answer is, “what do you need from a data center?”  If your data is mission critical to your business, then the facility you should be looking for needs to be absolutely bullet-proof.  What I mean is you need to make certain that not only is the data center 100% secure and reliable, but also that you are confident the provider you have chosen has taken the necessary steps to provide true Enterprise Class data center services.  As a guide, here are some questions that you need to ask each provider when choosing a data center: 
• Do you own the building the data center is in? (I’ve seen landlords get in the way of operating efficiently)
• How long have you been in business ?(a long  and positive track record means everything)
• Do you have multiple bandwidth providers? (the more diverse providers, the more redundant)
• Do you have multiple generators? (remember, redundancy is the key)
• What type of fire suppression is installed? (remember, “dry pipe/pre-action” means  water…yikes)
• Do you have 24/7 monitoring? (someone always needs to be proactively monitoring for issues)
• Do you have 24/7 support? (Murphy’s law….make sure someone is there to assist at any time)
• What are your plans for growth? (if they are not planning for their future, do they care about yours?)
• Are you SAS70 Certified? (shouldn’t your provider put forth the extra effort/expense to insure operational excellence?)
• Do you allow 24/7 access to the data center? (it’s your stuff, you should be able to get to it when you want)
• How do you charge for power? (metered power is catching on…..pay only for what you use)
• Do you monitor PUE? (if you’re concerned with energy efficiency, shouldn’t your provider be too?)

When I first started in the Data Center Services Industry, I was with an International provider working out of headquarters in NYC.  Man, I thought that was the place to be…..New York City, the most important metropolitan city in the world with the latest and greatest that technology had to offer. Things were going great.  We had a beautiful data center and NYC was overflowing with companies that needed our services.   Customers were lining up at our door….we couldn’t build cabinets fast enough.  The Data Center industry was on cruise control and I was driving it in New York City.    Then came Sept. 11, 2001.  We were located about 10 blocks from the World Trade Center – not that far when you’re talking about city blocks in Manhattan.  The city stopped, nobody was allowed access to our building for weeks.  Yes, the generators kicked on when the power failed, our multiple access providers allowed us to maintain connectivity and our staff did a great job keeping our customers online.  As we all experienced, everything came to a screeching halt after the attacks.  Without downplaying the tragedies of that day, my focus for this message is that although the data center performed exactly as it was supposed to, our customers quickly changed the way they viewed where their data center is located and their disaster recovery plans.

Well, now it’s 2009 and I’m fortunate to continue my career within the Data Center services industry with LogicalSolutions.net.  I followed the lead of a lot of my clients from NYC and moved away from the metro area and headed north to Upstate, NY.  Most of the customers I had in NYC either moved their primary  infrastructure out of the NYC data center and into one located in this region, or setup a DR site in a data center located in this area.  Either way, they quickly discovered that data center services provided in Upstate, NY are not only as good (if not better), but the price is right too.   One of the many things that Upstate has to offer is the climate.  Our climate lends itself very well for data center cooling and power management.  I’m sure you’ve heard that Yahoo has even recognized this and is building their newest data center in Buffalo.  LogicalSolutions.net has built its newest data center in Pittsford, NY – a suburb of Rochester.  With our data center located in this area, we are able to accomplish many things.  One of those is the ability to reduce power costs by utilizing the latest technologies by taking advantage of the cooler climate.  Combined with the ability to provide metered power, we are able to manage power utilization more efficiently which enables us to pass tremendous cost savings on to our customers.  When you are considering data center services, start to consider the Upstate, NY region for the energy efficient processes, robust backbone options, and skilled engineering support.

One of my first engineering professors was pretty old school, having earned his reputation long before the days of computer aided design, finite element analysis and precision engineering.  He was the first one to teach me about the ‘safety factor’ – something that every engineer already knows intuitively: “Take whatever you need to support the load, and triple it”.  If you were tasked with building a bridge that needed to support 200 Tons – build it to support 600 tons!

Over the past few days, I have recently been accused of ‘over-engineering’ another part of the Data Center – our Internet Backbone Providers.  While some Data Centers are comfortable having 2 connections to the backbone of the Internet, the lifeblood of our business – we added our fourth connection this week.  Yes, that is four separate Gigabit connections to four different bandwidth providers, any two of which can support the full capacity of our Data Center.

For 14 years, we have taken the uptime of our data centers and core network very seriously, learning along the way of course, though sparing no expense or effort to offer our clients the best assurance possible that their Data Center would be up to the task at hand.  We have always purchased twice the bandwidth needed by our clients, and will continue to over-engineer and reinvest in the data center to give our clients the piece of mind they need.

I wonder if that professor of 20 years ago had any idea the simple lesson taught would apply in many more ways than just designing mechanical things?
