Will virtualzation result in standardized servers

Virtualization how-tos
I work with an IT organization that has approximately 12,000 servers from five different vendors and 115 different model types. I assume this large number of model numbers is because each was chosen to do a single task and therefore was customized for that task (I am new to servers and virtualization). It seems that as the industry moves to virtualization it will result in a substantial reduction in unique model numbers as the IT moves to more standard type servers. Is this correct? Jim4522

Yes, that is correct to a certain extent. Each Virtualization platform has its own virtual hardware, in much the same way that each physical server vendor has their own physical hardware (VMware vs. Xen vs. Microsoft, etc.). Within a given company’s offerings, the hardware will be almost identical within a generation of products (VMware’s ESX 3.5 Virtual Machines can be easily run on VMware Workstation 6, for example, as long as the VM uses 2 or fewer vCPUs), although different generations of virtualization can result in fairly different sets of virtual hardware (the differences between ESX 2.5 and ESX 3.0 were fairly profound, although there was a direct migration path to allow for easy conversions).

So, within a given virtualized environment, you will most likely only have 1 classification of hardware (whatever generation of whatever virtualization technology you use), although there may be some different classifications of hardware between your environment and an environment that belongs to someone else who chose a different virtualization solution.
