Have you checked to make sure your not seeing any duplex or speed mismatches on the nic's in the server with the switch? Also, you might want to run the Exchange Best Practices tool on the server as well to see any glaring issues.

No as we did not think it needed it, the machine is not running out of ram. How do your clients connect to exchange, local Lan, Remote via RPC over the internet, Modes (Cached or Not), how big are their mailboxes, how many items in inbox etc. They are way to many factors to list. Local lan, Outlook Fat Client. In short I've handled Just as many if not many more users on a single raid 5 setup in exchange 2003 with no performance issues. How many raid cards do you have, makes modules setup etc. Junky raid cards will also eat up your cpu, since they rely on software etc. Two raid cards, Smart Array 642. No multi-path software installed. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Aristotle Zoulas Sent: Tuesday, December 02, 2008 12:59 PM To: Exchange Discussions Subject: Exchange 2003 Upgrade (sluggish performance) Hello Gents, we have recently upgraded out Exchange 2003 configuration to boost performance as it was a bit sluggish. Bellow is what we went from and what we ended up with. We basically added a disk array to an HP ML-350 and a bunch of disks. Afterwards we moved mailboxes and log files accordingly. I am pretty sure we did it right however performance is still lagging (badly at times). Users are complaining their Outlook is taking up to one minute to change folders. Any help or feedback would as always be appreciated. Thanks In Advance--Aristotle Zoulas Went From: OS+Exchange Install+Page File <<Mirrored Drives-C-drive>> Storage Group #1 with multiple Stores+Public Folders, all Transaction Logs--<<Single RAID 5 Volume>> We had performance issues across the board. Long Average Disk Queue length. Went To: OS+Exchange Install+Page File <<Mirrored Drives-C-drive-Internal ARRAY>> Storage Group #1 (Executive Store), Public Folder Store-<<RAID 5, three spindles, -- D-drive-Internal ARRAY>> Storage Group #2 (InfoWorkers Store + Managers Store)--<< RAID 5, three spindles --E-Drive-External ARRAY>> Transaction Logs (Storage Group 1)--<<Mirrored Drives-F-Drive-External ARRAY >> Transaction Logs (Storage Group 2)--<<Mirrored Drives-G-Drive-External ARRAY >> All mailboxes were moved to new locations using "Exchange Tasks" move mailbox method in batches. The Executive Store is approx 20GB EDB+ 5GB STM , the Manager store is approx 30GB EDB+2GB STM, and the Infoworker Store is 3GB EDB+1GB STM. What we are seeing: Overall Slow Performance, especially for Storage Group #2. Still have relatively long Average Disk Queue length. It seems the performance is worse than in the single RAID 5 configuration (IMPOSSIBLE) Did we do anything wrong? Could we be doing anything better? The machine is an HP ML-350 G3, Dual 2.8, 4GM Ram, with External Raid Array MSA500 G1. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] t.com Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
