I am aware of the TSM design that says the more disk volumes you have, the more it will spread out the I/O for better performance. I also realize a lot of this doesn't really apply what with RAID-5, EMC SAN, multi-terabyte storage, etc.
So, at what point does having lots of smaller volumes (for a disk LZ), not give you any more benefit, I/O wise? I have a 5.3TB SAN space on my new 6.2.2.0 server. Originally, I started formatting 200GB volumes then moved to 300GB, up to 25-volumes. Now I am adding another 5.3TB space and was wondering if I should continue with 300GB or jump to 500GB? Simultaneous sessions should not be an issue since most of these backups are Domino TDP and therefore single thread. I don't think there is a peak of more than 60-simultaneous sessions. The TSM server is a Dell T710 with 48GB RAM and 15K internal disk for the DB & Logs. Your thoughts?
