> How do you defrag a highly active mail server with 1000s of users? Purchase Diskeeper 7.0 server edition.
We defrag our disks constantly 24/7. If a file is being used, it will bypass it and work on the next file. At first , you system will apear degraded and taxed, but the more you use it, the faster the defrags. Also, we have some users with 300-400megs boxes that insist on a archive to be viewable while they travel.. Since these are archived, once defrag'd they noticed less droppings and faster updating of headers in outlook. Therefore, sucky NIC and badly optimized disks = major CPU suckage... Especially the IMAP4 process. Prior to 24/7 defrag, IMAP would hang at 100% 1-2 minutes, after defrag, 3-10 seconds... Now zero%, just upgraded last week to a quad xeon... :) Cheers! eddie :) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Sanford Whiteman Sent: Wednesday, October 16, 2002 4:22 PM To: Kelly Britt Subject: Re[2]: [IMail Forum] Upgraded from 6.x to 7.x and feeling frustrated. > These machines were the Intel ISP series, the use the Inteal 82559 Fast > Ethernet Lan on Motherboard Swap it. > How do you defrag a highly active mail server with 1000s of users? "Highly active," again, requires metrics so that we can compare with successful configurations. The more active, the more urgent the need to defrag. If it takes downtime for scheduled maintenance, do it anyway--hey, would you rather be rebooting, and getting no help from the list until you defrag? There's no reason to leave out the essential step on easily fragged filesystems. Remember, it'll take less time to defrag the more often you do it. > I did create a new empty spool directory on a newly formatted > partition on a separate drive. ...and now for the mailbox drive. > I take it from the "here we go again" comment that this is a typical > problem for users upgraded. Maybe the product just sucks? It would appear from reports that 7.x is less tolerant of bad NICs than 6.x. It also does have more overhead in general, so is more sensitive to fragmentation, storage load balancing, et al. You would need to already have problems for 7.x to point up these areas. -Sandy To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
