We use the following:
I) p550 - 2CPU - 4GB RAM - 2GB HBA's - AIX v.5.3 - TSM v.5.3.5 - 250 TSM
nodes - about 2.4 TB of daily change - Connected to a DS4800 & 3584 (6 -
LTO2)...
Storage Lun:
RAID5 - 140GB/15K FC Drives - 1.226TB LUN on the full array - 64k segment -
Caches Enabled
Database LUN:
RAID1 - 140GB/15K FC Drives - 100GB LUN on 136GB Array - 64k segment - Caches
Enabled
Log LUN:
RAID1 - 140GB/15K FC Drives - 20GB LUN on 136GB Array - 64k segment - Caches
Enabled
In the next month we will be adding around 120 nodes.
Also, we will be migrating half of the nodes to a second datacenter's TSM
server (nearly identical setup), so that we will have roughly 200 nodes in each
datacenter.

Anyone out there using a DS4800 that wouldn't mind telling me what you used for
cache settings and segment sizes for your storage, database and logs? I've been
looking at all the docs out there and found some inconsistencies and would like
to hear what you've found seems to work best.
Thanks and feel free to contact me directly if you like.
