The 1850R doesn't go any faster than 600Mhz. The bus on them is 100Mhz. Depending on what services you are going to offer on these boxen and the number of clients being serviced should help you decide on the hardware. I run lots of 1850's serving static webs and SMTP/POP3. My email scanning takes place on Xeon based machines...2Ghz and higher.

I wish to thank everyone for their testimony regarding this "CentOS on Compaq Proliant Rackmount Servers" thread. The basics have been answered and I am grateful. Even though I can fund brand new shiny latest greatest fastest I think it is a foolish waste of money unless there is a true "need". Is it currently worth getting used dual PIII 1850R's or should I start with used dual PIII DL380's and like 1Ghz minimum processor speed? I couldn't find used 1850R's on eBay with more than 600Mhz. Although there are not thousands upon thousands of clients there is A LOT of bandwidth to service. Remember, the goal here is to have a bunch of happy little CentOS boxen purring away. :) I have several custom built units, yet I need more! - rh _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
