Hi all,
We're in the process of planning to move our 40 or so physical servers to a
virtualization platform. It's early days yet so we haven't landed on a
platform yet (VMWare, HyperV, possibly KVM?) but I was wondering if it
would make
sense to virutalize our LTSP servers as we move to Ubuntu 12.04 LTS. We
currently support about 120 thin clients divided evenly between two 4 core
opertron servers with 16 Gig's of ram each. It turns out that we rarely
use more than 50% of our ram even with 40+ simultaneous clients per server,
but often push the CPU load to 10+ and disk i/o to 6k writes/sec. So I
figure that lots of CPU's would be a good thing. And of course the virtual
environment would be supporting other servers as well (windows, linux)
doing file-servering, active directory auth, web serving etc. As we bring
on more thin clients, it would be great to be able to spin up an additional
LTSP server at the drop of a hat, distribute the load between servers etc.
Has anyone gone down this road yet? Any web resources that you could point
me at would be appreciated. Any ideas about why this is a stupid or great
idea are also appreciated.
Thanks!
John
