VC and License server on the same copy of Windows is actually recommended from VMware. If you decide to add SQL to the mix, then you will have to provision more hardware (virtual or physical) to offset the demands made on the box... plus you would need to make sure SQL started before VC in the service order otherwise reboots might cause a problem...

Personally, I would recommend keeping your VC DB on separate box...

I've got VC, licence server and SQL 2000 all running on the same physical box. Not had any problems so far...

SteelEye is the only company I am aware of that has a failover solution for Virtual Center.

Hello,

I use a ML370 G2 (Dual 1.4GHz) with 6GBs of memory. I added in a dual port ethernet device and run VC, SQL, License Manager, and HPSIM w/all its plugins. In addition, I run an NFS server to handle how I do backups as this is also my backup server.

Never a problem and it works fine. My backup for VC/License Manager/SQL is a VM. For HPSIM, there is another VM. As my ultimate backup for License Management, I use a laptop that sits in the server room waiting for use. I have had my ESX servers have a license management problem and the only solution was to have it available on a physical box. THe laptop while not the fastest was handy, so I keep it as the ultimate backup in case I need it.

Failover clustering whether using SteelEye or MSCS is all that you really need.

Best regards,
Edward
