DS4700 lun recommended settings for stgpool, db and log

[marcinek]

Hi,
I'm setting up the DS4700 for TSM. Did any of you foud some documentation about recommended settings for LUNs devoted for db, log and stg on smal DS systems like 4700.

My questions are:
I have two controllers A and B - each LUN can prefer one of these. Which luns should share one controler and which should be separate: I assume db and log should go through sparate, bu where to put stg?

Are there any cache settings I should consider? Block size?
All my arrays are RAID6 and I can not change it.

best regards,
marcin

Hi. In case someone except me needs that answer, there is a nice chapter about TSM and midrange IBM storage in this redbook: http://www.redbooks.ibm.com/abstracts/sg246363.html
It's somewhere between typical applications.
