[THIN] Re: VMware & CPS 4.5

Bingo.

I didn't mention, but I guess I should have.  Your mileage may vary 
considerably and it really should be tested in your own environment.  I did, 
however, want to express that in our environment we did see significant 
improvements by upping the RAM in our presentation servers.

This is entirely dependent on application and system utilization. The 
additional RAM gives you more user space memory but the 2GB kernel limit is 
still there so in some cases it works and in others it does not

We get about a 35% increase in users when tossing 8gb of RAM instead of 4gb in 
a CPS4.5 server using PAE.

In general I have seen that 4GB of RAM is the maximum amount of memory that 
Citrix boxes will efficiently use on a 32 bit Terminal Services Windows server 
operating system.  This has to do with the 2GB kernel memory limitation:  
http://www.brianmadden.com/content/article/The-4GB-Windows-Memory-Limit-What-does-it-really-mean-

As a result, there are two options if you want to use more powerful boxes with 
much more RAM in a Citrix / TS environment, either run 64 bit windows terminal 
servers, or virtualize with ESX.  The customer did not have applications that 
would have taken advantage of a 64 bit architecture, so the only other option 
was to go with ESX and virtualize for them.

They made the decision on their own to not look at VDI as an alternative 
solution...

Silly question but why would you just not run the apps natively on the box 
instead and isolate instead if you have app co-existence issues?  Seems like 
you could fit more users on again?



We have taken the decision to use VMWare for small apps (where we can't 
isolate) of low user numbers but typically only dev as we don't believe it 
scales as well on VMware for heavily used prod servers.

I just set it up for a customer in a production environment:  2 HP DL380 G5 
boxes, with dual quad core CPU's and 16 GB RAM, backended with an HP EVA 4000 
FC SAN.  We have 3 PS 4.5 virtual machines on each host getting 20 users on 
each vm comfortably.  They have a pretty heavy application load too (Oracle, 
Lotus Notes, etc...)  and they are publishing full desktops to all users on 
WYSE SX10 thin clients.  We did bring DRS automation down to manual.  All in 
all, so far so good!

Our current production CTX environment = MPS 4.0, Win2k3 sp2 hosts on VMware 
ESX 3.5.

Our standard VM build has 2 procs, 3gb ram and we average about 45+ user 
connections per host. Our environment is published app based, which lets us 
spread the load around a bit better, no full desktop. Physical boxes running 
VMware are HP blades, 16gb ram, 4 proc. Dependant on app load and usage, (we 
silo off the heavy use stuff) your mileage may vary.

That link Greg sent has some good recommendations; from my own experience:

- the vmware tools install by default adds a component into user profiles 
"hgfs.dat" which can be a pain to deal with. (greg's article covered this). 
Sort out how to handle this before allowing users to login.
- Use manual DRS automation if you have a Citrix specific cluster setup in your 
ESX environment. Automated DRS vmotion during production hours with dozens of 
users connected can hang up a VM.

We have virtual MPS 4.5 boxes in testing, but I can't say we've put any serious 
user load on them yet.

We tried it in an ESX 2.5 environment and the performace was horrible.  
Supposedly its been greatly improved in an ESX 3 environment but we haven't

Hi,



I've a customer who wants to run CPS 4.5 in a VMware ESX environment. This will 
be for production.



Has anyone set this up in a live environment before? I've only ever set it up 
for a dev environment. Any tips or recommendations? Should I discourage them 
for doing this and use straight tin instead?



Thanks for any help,

Chris.
