gbarnas -> RE: Server virtualization penetration in your organization (5.Jan.2011 10:33:47 AM)

I would not normally resurrect an old post, but it looks kind of dead around here.. :O We're an IT consulting company with about 90% of our server infrastructure virtualized. We have 22 Windows servers, 19 of which are virtual. The physical servers include a pair of TMG Firewalls and a server that runs vCenter and Backup Exec. It's all backed by a 4G FC SAN with about 18TB of storage. We use two HP DL380-G5's with dual quad-core processors and 32G RAM to host ESX 4.1. The physical servers: 1. W2K8r2, DL360 G4, 4G - TMG Firewall - This is our front firewall and is physical simply because we now have more than 4 network connections to it. In the past, we used ISA-2K6 on a VM. 2. W2K8r2, DL360 G4, 4G - TMG Firewall - This is our back firewall. Originally a VM, we experienced some performance issues that were not present in the original ISA-2K6 system it replaced. 3. W2K8r2, DL360 G4, 4G - Management - I felt more comfortable with a physical server for vCenter, and we needed a physical server to communicate with the tape library. We have a couple of small clients who were 100% virtualized. 3-5 Windows servers and half a dozen to 10 XP clients on ESXi was typical. Either Wyse or Linux-based thin clients were used. They now have a few laptops for the outside salespeople and senior staff, so aren't at 100% any more, but still have a high level of virtualization. Most of our mid-sized clients have embraced virtualization, with 3-4 VM hosts replacing 10-30 physical systems. Only a few still have physical servers, mostly due to special hardware requirements such as Fax, multiport serial, or Phone/Voice cards, high-load SQL services, and old software with license restrictions.
