You can purchase the 2850 with Dual Core 2.8ghz Xeon, but it is a pricey upgrade of $959/cpu full retail. I have no idea what dual core Operton's cost however for comparison. More importantly perhaps would be if the Citrix claim of 3x more users is from a true 64bit CPU like an Operton, or if they achieved the same results on an EM64T "64 bit" CPU like the Intel Xeon's. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Martin Stephenson Sent: Thursday, October 13, 2005 5:52 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Server Specs Hi Keith, If your not totally committed to Dell you may want to consider a server which has Dual-Core AMD 64 bit CPU's. From a quick search I discovered that Sun now sell a 1U server based on a pair of these CPU's, its the Sun Fire V20z ( http://www.sun.com/servers/entry/v20z/index.jsp). While most people are not rushing into 64 bit Windows you may find that you want to install a 64 bit O/S on these servers at a later date, in the meantime you will get the performance benefit of Dual-core architecture. As a bit of background info you may want to read the Whitepaper recently put out by Citrix on x64 Windows - http://support.citrix.com/kb/entry!default.jspa?categoryID=924&externalI D=CTX107341&fromSearchPage=true Cheers, Martin.

These servers (three of them) will be hosting Microsoft Office products, Novell GroupWise, and 1 vb app (16MB memory usage/user) that is the front end to a SQL database held on another server to 180 users. All user data will be stored on a Novell server accessible through a mapped drive. I'm looking at the Dell Poweredge 1850 with dual 3.8 Xeons /2MB Cache, 4GB RAM, and raid 1. I plan on using 2 73GB 15k RPM Drives. What raid controllers do you use? The embedded one (PERC4ei), PERC4eDC-PCI Express (+$415 ), or the PERC4/DC for an extra $415? From your experiences, am I asking too much from these servers, or should I have more? Thank you for your continued support. This list rocks. You guys have given me answers for questions I did not know I needed to ask.
