The server i'm having high fragmentation is a Lotus Domino server. I
talked to lotus and they do not recommend defragmentation while domino is
running.
I'd probably need a 4 to 8hr outage window to defrag the drive.
Today i had a small outage window on the server so i upgraded the Raid
Controller Firmware, Server Bios and Upgraded the broadcom GB drivers.
For the time being the backup server isn't having slow backup performance
since the updates. Yeah!
So i have some breathing room until i can get a long outage window.
In the past, slow performance has shown up after two weeks.
At anyrate, i still need to defrag the drive.
