Terminal Server on virtual server

[Guest Jeremy]

Hello everyone,

I'm curious to know if anyone is running there 2003 terminal servers in a

virtual environment. I currently only have 50 users split between two 2003

TS. I have been debating on going virtual, but don't want to lose on

performance. The driving force is going green. Thanks for any feedback.

Google this group for more information on past debates about this

subject.

 

So far the debate leans towards don't but that depends on the

the software you use.

 

Consensus is if on Windows 32bit, it would not be wise but it

may be a go if the host is Windows 64 bit with a Windows 32Bit

client.

I do it all the time, but only for testing. The performance hit is too

large and we can't afford to throw hardware at it....

Thank you for the feedback Hank. It's funny, the Sales guy tells you oh, yeah

no problem at all. oh well, maybe next year.

And for you it may be ok. Truthfully, 25 users per server is a pretty

low number generally. Depending on what exactly you are doing from an

application standpoint, you may very well be able to virtualize these

servers and have fine performance. Let me ask you this: Have you ever

baselined your servers so you know the maximum number of users you can

get on a server? Without this information, you really have no idea if

virtualization will work or not. The only way you'll know is by

actually virtualizing and seeing if it works.

Don't take my reply to mean that what you want to do isn't possible. The

hardware I have isn't powerful enough to absorb the performance hit. In

a test environment, my concern is functionality. Does everything work as

expected? We tell testers up front that performance is not to be

considered. Virtualization is clearly being done by a lot of folks and

very successfully. I think my warning is that you need to evaluate the

situation you are trying to virtualize very carefully and make sure that

the hardware you have is sufficient for the task. As Jeff Pitsch

indicated, an average of 25 users isn't, by itself, a huge load.

 

I guess that my point is that a virtual server running on a specific

hardware platform will, IMNSHO, suffer a performance hit. Given

sufficient hardware, that may be an acceptable hit....

Re: Terminal Server on virtual server

 

I really appreciate the feedback. This is what I'm working with:

 

Dell PE 500sc - old DC - going away soon.

Dell PE 1800 - Terminal server - would go away if we virtualized.

Dell PE 2850 - Exchange

Dell PE 2950 - File Server

Dell PE 6850 - Terminal Server

EMC SAN

 

I know thats not much detail. They all run 2003 Std, except the 6850 is 2003

Enterprise. I don't have an accurate baseline. I may try setting up a virtual

server on the 6850, and have some people test it out. And no i don't have a

baseline. I will create one before adding the VS though. Thanks and let me

know if you have any other feedback once you see what i'm working with.
