No experience with IBM kit myself, but have you used diskpar to align
tracks/sectors optimally? Pierre Bijaoui's talk at the MEC highlighted the
importance of this when dealing with a SAN.

Subject: Exchange 2000 and IBM's FAStT SAN
Exchange 2000 SP3
Windows 2000 Advanced Server SP3
Trend Micro Scanmail 6.x
LUN 1 = Storage Group 1, 8 Disks Raid 10, 136GB
LUN 2 = Transaction Logs for SG1, 2 Disks Mirrored, 36GB
LUN 3 = Storage Group 2, 8 Disks Raid 10, 136GB
LUN 4 = Transaction Logs for SG2, 2 Disks Mirrored, 36GB
While monitoring the Physical Disk - Disk Queue Length for all 4 LUNS I
noticed that on LUN 1 my Queue Length peaks at 100 - 150 periodically and
averages about 10. Is this normal? I only have 10 users on this server at
this time and am scheduled to migrate another 700 over this weekend. The 10
users have not complained about performance but I always thought that the
Disk Queue Length should never exceed 1 per disk. Any thoughts? Anyone
else using the FAStT SAN solution?
