[THIN] Re: Citrix WAN design - the ultimate design

Ditch frame for MPLS. 4mb links sounds overkill for 40 users given the 80% ICA/20% local apps, but that will also depend on their other internet traffic and if you default route it through the internet at your head office, or if your provide lets you do default internet routing out through them and you go that route.

As a bandwidth reference point, I ran an office of 80-100 users off a mix of 100% ICA with IE as the only local app. They had a 10mb link back to the corporate office but that link never saw over 30% utilization unless someone was abusing the internet. Internet was centrally routed through corporate, so I don't have a metric of how much was bandwidth used by IE for general internet browsing. I ran another office of about 30 users with the same ICA/IE mix and centrally routed internet off a 3mbit link and typical load was about 30-40% usage on that line.

I abandoned fighting with the UPD and native drivers and purchased triCerat ScrewDrivers and it was, hands down, the best thing I did for my Citrix farm, thus printing was centralized. My farm wasn't massive, at 7 servers, but it was still a pricey up front investment, but it was worth every penny.

Subject: [THIN] Citrix WAN design - the ultimate design

HI

I have the fortunate situation where I have the opportunity to redesign our company WAN links / Citrix design. Is there a best practice for numerous small branch offices (10 - 40 users)? We have 30 sites around the country connected via frame relay links. If you had the opportunity to design your farm from new how would you do it??. Application use is fairly simple (Office, Outlook etc). Im not looking for assistance on Citrix farm numbers, more high level.. This is what Im thinking:

4Mb WAN links from Head Office to all sites (direct, not via other branches) Centralised Print Server in Head Office Citrix Presentation Server 4.5 Tricerat ScrewDrivers for Printing

Would this be a good start? Would anyone add Citrix WANScalers also or would 4Mb links be sufficient for sites with 40 users or less?

Am I on the right track?

Thanks
Ang
