April 21th was the big day the VMware community was waiting for. Finally the next generation of Virtual Infrastructure was release by VMware. As already announced the new name for this bundle of software is vSphere! It was announced by VMware’s CEO Paul Maritz during a simulcast. You can still view the presentation here.
So the word is finally out. Let’s have some fun with this new product, but that probably won’t be a problem because of all the nice new features. And remember this is just the beginning. After this initial product release more will come. VMware will release new product which will integrate with vSphere in the next couple of months. The list can be found here. And not only VMware is going to release new products, but also the partners will release new innovative product which will make vSphere even a better product. So you’d better stay virtually connected to get the latest update!
Starting server virtualization is always a difficult task to begin with. First thing you need to deside is which servers you want to virtualize (Well some pointers in that direction : all of them!). But with all difficult tasks you need to take a structured approach. Business isn’t waiting for you to bring down their critical applications. Therefor approach it one step at a time. This gives you the structured approach you need, slowly entering the learning curve of virtualization and giving your IT department the time to adapt to all virtualization technologies.
I would always advice to use a capacity planning tool for your “physical” server environmen, before beginning to start server virtualization. Tools like VMware Capacity Planner and Novell Platespin PowerRecon give you a good insight in what the workloads are on your physical servers. This will then be presented to you in a report with an advice for the most optimal virtual workload distribution across your “yet to be build” virtual infrastructure.
Besides these technical tools, you can also use SCOPE. A conceptual tool by Danielle Ruest and Nelson Ruest. SCOPE lets you quickly identify which workloads to start with. Begin in the lab, maybe even with the lab machines themselves, and slowly move your virtual workloads into production.
SCOPE is the step-by-step approach to virtualize your complete environment. So virtualize your environment in the following steps :
Easy workloads; Servers that don’t consume a large workload and can be easily virtualized.
Production workloads; Server used by users on a day-to-day business but that aren’t critical to your line of business
Operational workloads; These server are mainly used by the IT department itself. Servers which demand a high workload but aren’t business critical
Complex workloads; Server that are, already without virtualization, complex to maintain. These includes the servers which have common applications installed on them in mostly enabled with clustering / load balancing.
Special workload; Each IT infrastructue has those servers which require special attention. When finishing the virtualization of your complete IT infrastructure, these servers will finish the job.
So as you can see, SCOPE gives you a five step approach to virtualizing your IT infrastructure. This will hopefully help you in creating a good virtualization strategy!
Video has been on the net some time now. It was published before VMworld 2008. Still I love to put it here to show you what an amazing feature it is. It’s also great because you can see what the VMware product line is capable of. The video shows you a normal business day with a 4-node VMware cluster being hammered by your average production servers accompanied by some very nice music.
