Servers have been relocated today to our newer server room.
This has double air conditioning units, so offers me more A/C reliability.
I also updated the memory in all machines to 16GB for servers and 12GB for virtual server machines.
One virtual server machine only has 8GB, as I could not make it boot with the other 4GB installer.
Just not clever enough I guess...
I am planning to offer Windows 2008 virtual machines, and its minimum memory requirements is quite a jump from the 64MB I give each virtual linux machine. Hopefully I can get Windows 2008 running in 512MB, allowing me to run the same 16 virtual machines per server, and thus 64 or more virtual machines. I will endevour to keep 32 available for the public when students are not actively using the system.
