RE: 2000 server sizing.

4000 is the recommended maximum (I believe the biggest reason was I/O usage from MAPI users).  We had a specific circumstance where we had the hardware already available so we took it.  I haven’t set myself up for detailed reporting yet, but the CPUs were running nicely at around 20% last week.   -- Matt Lathrum General Dynamics Decision Systems                     When cryptography is outlawed,              bayl bhgynjf jvyy unir cevinpl.   -----Original Message----- From: William Lefkovics [mailto:[EMAIL PROTECTED]] Sent: Monday, June 03, 2002 5:31 PM To: MS-Exchange Admin Issues Subject: RE: 2000 server sizing.   3800 users is the supported maximum for that config, right?  And the CPU musn't go over 40%...   -----Original Message----- From: Lathrum Matt-P55173 [mailto:[EMAIL PROTECTED]] Sent: Monday, June 03, 2002 5:28 PM To: MS-Exchange Admin Issues Subject: RE: 2000 server sizing. We are running E2K SP2 on a Compaq Active/Active cluster with two Compaq 8500s (4GB RAM with 4 PIII 700MHz Xeon w/2mb cache) and a SAN configuration of over a terabyte.  We just went live with it a month ago.  We have had two instances where the cluster had mail queuing problems and we had to play with failing it over and getting the SMTP service stable.  We have about 3800 users connected in total.  We also have Symantec Anti-Virus and Filtering for Exchange installed.  No problems with CPU load.   -- Matt Lathrum General Dynamics Decision Systems                     When cryptography is outlawed,              bayl bhgynjf jvyy unir cevinpl.   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, June 03, 2002 4:45 PM To: MS-Exchange Admin Issues Subject: 2000 server sizing.   We have finally implemented AD and are now looking into migrating to E2K. Currently I have 7 boxes set up to handle Exchange 5.5.   5 for user mailboxes (about 500 users each) 1 for Public Folders 1 for IMS   I have posted before asking if anyone was using Exchange 2000 in a clustering or SAN configuration. I seem to remember that some had said that they found a benefit to connecting to the SAN but that there seemed to be a consensus that Exchange did not really do well in a clustering environment for a site of 2500 users. Is this correct?   That being the case I am looking at bringing E2k up on a Dell 4600 2GHz/512k XEON with 2GB memory and 4x74GB RAID drives. Has anyone had any experience running Exchange on that type of hardware and size? Also, when I first brought up my 5.5 site we were told to keep it at about 500 mailboxes per server. Do I still need to follow that with 2000?   I know that there are a lot of variables and that there is no one right setup for everyone, but I am going in the right direction?     Ken Powell Systems Administrator Clark County Office of Budget and Information Services (OBIS) Vancouver, Washington [EMAIL PROTECTED] Voice: (360) 397-6121 x4658 Fax: (360) 759-6001   List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
