[THIN] Re: Citrix on VMWare

I have heard that XenServer only takes a 20-25% performance hit. We have
multiple Citrix VM's per hosts in addition to other VM's. Definelty worth
looking at XenServer.

Half is pretty bad... XenApp runs pretty good on XenServer platform. And
if you believe Citrix's engineer it is a 20% performance cost with 32 bit
and 8% with 64 bit... Those are 1 to 1 (1 VM per Host) numbers, you
should be able to reduce the 20% performance cost by running multiple
instances.

Presentation server works fine on ESX. The only problem is the
virtualization hit. You are only going to get about half as many users on
the Citrix vm as compared to physical.

Actually I have 6 or 7 PS 4.5 servers running as VMs, but they are low
usage, more utility type servers. The main section of my farm is 34 IBM
HS21 blades and I'll be adding at least 20 more in the near future. They
run a couple intensive apps, that with dual quad cores and 4gig I can get
about 20 users per server with good performance. I'm wondering if I could
expect the same performance out of a beefy VM.

I actually was just about to write this list with the same qeustion.

Thanks George.

I'm looking at migrating an old EOL dell 2650 to Xenapp 4.0 as a VM.

I'm curious how many folks are Xenapp servers as VMs with VMWare ESX? What
is the performance and stability like?
