Hi 

I would stick to 100GB diskpool volumes as many as you require.
Its not necessary to split into different LUNS as the SAN takes care of
itself and it is RAID 5 hopefully.

I have learnt to keep to smaller logical units for every thing in TSM.
Makes for better management and migration etc.

Regards

Subject: [ADSM-L] New TSM Layout

We are in the process of designing our new TSM server. As part of this
we are also going to give it new SAN drive space. 

 

Currently we have 661 Gig in our disk pool and we are upping that to 900
Gig. What our questions is how should we partition that? Our current
pool is in 7 partitions but I was thinking more like 3 or 4 partitions.
Are there any pro's/con's with going with fewer disk partitions?
