Why not just leave it one box and dump all of the users into that? I
t’s all the same app, right? What are the VMs for? I’m not
challenging it; I just don’t get it I guess.

Use Nehalem processors… But not 64 gigs.. 64 Gigs is an odd number
for the Nehalem architecture. Either 48 gigs with 4 gig DIMMs or 96
gig DIMMs. Pick a platform that run either of those memory configs
at 1333MT/s.
Use Citrix Provisioning Services. Just do it. But make them
Physical Boxes.
Application virtualization will help you realize a single silo.
Partition the Server, don’t over subscribe CPU or memory. So if you
have a box with 32 logical processors (16 cores, 16 HT), then plan
for 2 x 16 VMs. Using CPU pinning/masking may also increase your us
e density.

Subject: [THIN] Design Ideas?
Hello,
We currently have a farm with about 50 servers, both physical and
VMWare VMs, all Xenapp 4.5, 32 and 64 bit. 28 of the physical
servers are for a single application silo, running 2003R2 64-Bit
running on IBM HS21 Blades, Dual Dual cores with 5GB. I’m looking a
t changing the design of this one application silo (user count is ge
tting ready to go way up) and am looking for some ideas.
The boss gave me 2 requirements, the fastest performance we can get
and a smaller foot print. One idea we are looking at is going to
big servers, IBM 3650s, 12 or 16 Cores with 64 Gig RAM, running
Xenserver with Xenapp VMs. However, I worry that we’ll run into a
bottleneck somewhere and not be able to get the number of VMs needed
for the performance I want.
What is folks’ opinion on Xenserver VMs verses smaller physical mach
ines? We run fairly good with ~15 users per Xenapp server on the H
S21s, do you think the VMs can perform well enough to get more users
on them? Basically I’m looking for any ideas for better performanc
e while being able to handle about a 30% user increase.
Thanks,
