Hey Folks - We need your help. We were hoping, we could gain from your experience with implementing server virtualization. When should we be using Red Hat Virtualization, Citrix Virtualization, Xen Virtualization, Microsoft Virtualization, Oracle Virtualization and VMWare. I will be very interested in learning from your first hand experince. I will also like to know, under what situations is one virtualization prefered over the other. - Thanks for your help
We just implemented VMware clusters in our main 5 datacentres. I just did the course, and it seems like a pretty awesome solution.
We currently have over 800 production servers (mainly windows) and are hoping we can reduce this number by at least 50% over the next 5 years. SO far we are seeing a ratio of about 10:1 VMs on a physical ESX server.
Obviously it doesn't suit every application, but it seems to be working well for most (File/Print, Domain Controllers, Citrix, Exchange etc) - just steer clear of heavy I/O type apps like SQL
