A VERY good point, Jason.  I'll do the research with our central IT department today.

Tom (and others considering virtualization),

Granted I'm unfamiliar with your school's relationship with a central IT group for your campus, but if possible I would recommend avoiding reinventing the wheel. For schools with a good relationship a Shared Services model can be a very good thing, freeing your Law School team to focus on services and not hardware.

For example, we manage 18-20 virtual servers to support our needs in both development and production, but those VMs run on an ESX farm with university IT. They use many quad-CPU, 8-core hosts with 256GB of memory all redundantly connected to both network and SAN infrastructure for full DRS/Vmotion support. We get to focus on the applications and OS and leave the hardware and most ESX licensing, configuration, and management in someone else's hands.

Just a thought, which may not be viable for you, but I wanted to share in case others could benefit from such a discussion/offering within their university.

Hi all,

I'm in the process of planning a virtualization initiative for all our web-based services.  I plan to run 3 VM applications immediately and want room to expand to maybe max 5 more in the future.  Each application will have its own function, but none will ever be tasked heavily for any extended period of time.  I have faith in the VMWare product line but I'm not sure what's overkill or under-powered.  Does anybody have experience with VMWare server products specifically "Workstation" and/or "vSphere"?

My server specs:
Dell Poweredge 2950, 8-core Xenon, 8GB Ram, RAID-5 10Krpm SCSI, VMWare ESXi capable hardware, RedHat Enterprise Linux 5.5

My VM requirements (applications):


1.       RedHat Enterprise Linux, cPanel, 10-20 Apache virtual hosts, up to 20 MySQL databases

2.       Fedora 13, Zoneminder Security Camera DVR, SAN-iSCSI (storage on offline dedicated server)

3.       RedHat Enterprise Linux project management and web development server

4.       Up to 5 more applications running various light duty work

My question is, based on the scope of our requirements, could I just run headless application instances on VMWare Workstation or would vSphere be the better choice?
