The firmware upgrades did not resolve the problem with disk performance, even though we had a good couple of days. Sun’s final analysis led them to the conclusion that the disk array on which mailboxes reside has simply reached a saturation level in terms of I/O rate. This will mean that we will have to get a faster disk array.

IMAP and POP3 and Webmail Slowness III
Firmware upgrades to the mail server disks have been applied. This had little effect on performance. We’re following up with Sun to determine next steps.
Mail Server Maintenance
All email service will be unavailable from 5PM to 6PM today. Firmware upgrades will be applied to address Webmail, IMAP, and POP3 slowness first noted in this entry: http://www2.ups.edu/ois/nssg/blog/maintenance/archives/000449.html
IMAP and POP3 and Webmail Slowness II
Sun has identified some issues with our disk array configuration. They have provided some new settings for us to apply. One of the changes has been made, with little effect on disk performance. The other two changes will require that the email server be shutdown. We are scheduling this right now. Please refer to the “Scheduled Outages” (http://www2.ups.edu/ois/nssg/network/alerts.shtml)page for the latest information.
IMAP and POP3 and Webmail Slowness I
We are currently experiencing disk performance problems on the mail server. This is causing slowness and problems connecting with Webmail and POP3 and IMAP clients. We are working with the hardware vendor to correct the problem.
