Hi guys, I'm wondering if more people are running TSM in a cluster configuration. We always used Linux clusters based on Veritas Cluster Service (VCS). Ever since we were switched to IBM hardware we also had to switch to a different multipath driver and that is where the problems started. We always used Powerpath together with EMC hardware which worked OK. VCS only supports Powerpath and Veritas DMP and because we switched to an IBM Storwize v5010 we switched to DMP. However, DMP doesn't seem to be able to properly handle 4 an 8K I/O's so write performance on the database volumes is awful. Veritas doesn't seem to be able to fix this issue, so I'm looking at alternatives. What clustering software are you guys using and what is your experience with it? Thanks for any reply in advance!
