Citrix V's Terminal services
Posted on 2006-11-25
I have a 7 server NLB'd cluster of terminal services, we have about 400 concurrent users. The problem is we have lots of problems with remote sites in tbandwidth terms, well theres the thing, i dont think throwing bandwidth at the problem is going to help the situation. Basically when a remote site connects (we have a point to point 1Mb, they get to the internet through our main site) rdp bursts to take the whole meg on first start of a brower session (and it would burst to whatever link we put in), this renders the whole link staurated and useless. Or I think any page that is busy with grahics. We also have problems with every remote site in that sessions stick on their thin client PC's. Basically a nightmare.
Funnily enough we were advised to get a 1mb Point to point link to this site to replace the ADSL we had. I hadnt started at the company when this was agreed, however as i said i dont think throwing bandwidth at this is the issue. Anyway I think this has made the problem even worse as when someone wants to get to the internet they now have to come through the central site through the p2p link, rather than the ADSL going straight out and not bothering our central internet pipe.
I belive that Citrix maybe the answer, in that we can balance the servers better than NLB can and we can have more granularity on what we can do to conserve bandwidth. Or we can use Published Apps which i believe run everything on the main server thus helping as well.
Has anyone any thoughts on this, I would be most appreciative on some backup to my thoughts before I write a doc asking my managers for 10k for citrix licensing. I WILL get the money if i make the choice a very real one i.e get citrix or put up with crap performance and tons of unhappy employees.
