Is Terminal server the best solution?

By bspeck ·
I currently have 28 IBM Eduquest machines running Novell 3.12 and ICLASS. My local vendor is suggesting we purchase a terminal server to make these machines act like newer machines. I know what we have is outdated, but is this a realistic solutionto bring this lab up to the 21st century. We want to be able to effectively use the internet, Office 97, and several other educational titles. How many titles am I realisticly limited to? How fast of "machine" can I expect if we put in a dual Pentium 700Mhz packed with RAM?

Ask your vendor how big the server is.

If they tell you that you will spend less than 60K for the needs of 28 clients, they're yanking yer ****.

Terminal server works great. But it has tremendous overhead on the server side. That means muscleand >>>lots<<< of it.

That's just server side. Client side doesn't require much but, it's not a dumb terminal. You will also have to put some horse-power on the client side.

Additonally, a tip, ask about the web-client. If they answer positively then they may actually be OK. Otherwise, they don't work on this regularly and you may want to run.

Can't help you with the "best solution" question. You know you situation better than I.

Terminal server solutions look good on paper and can allow the use of older PCs with up-to-date applications. Before implementing I would suggest you investigate all the options thoroughly.

As a rough guide, you should be able to work with upto 40 applications and 20 logons per 1Gb of RAM on the spec of machine you mention.

The magic formula

by Helper In reply to Is Terminal server the be ...

1. There is acctualy a way to figure out the amount of ram required for your specific enviroment.
The formula is count the number of 32 bit applications you expect an average user to be running (i.e if the user opens outlook and msword and ie5.5 atthe same time and does not close them that would count as 3)
times 10mb of ram. (i.e 3 apps x 10 mb = 30 mb )
Now count the number of 16 bit applications you expeect an average user to be running
times 16 mb of ram (i.e for this example we will say 5 16 bit apps so 5x16 = 80mb) so the average user would consume 110mb of ram per session. if you had 40 users you would need 4.4gb of ram.

2. The number for the processor is the hard part. I would suggest you buy a dual processor machine with a fast disk subsystem.
