We were using zLinux to host TSM servers with TSM release 5.5 and were happy with performance and memory consumption. We backed-up 100s of servers a night using a z10 processor with multiple IFLs. Once we upgraded to TSM 6.1, the memory consumption became prohibitive (8+ GB). We kept increasing the memory allocations and even after going through all of the DB2 performance tuning parameters for TSM 6.1, we could no longer justify the additional memory cost as compared to stand alone servers for TSM 6.1 so we have moved TSM off of zLinux.
