We are considering migrating our TSM systems from AIX to Windows 2003. I know that the experience of the forum participants is that AIX provides superior I/O performance, but where is that threshold?
These are our system details. I'd like for anyone with experience with a system of similar size to share their experiences regarding Unix vs. Windows. We are currently running TSM 5.1.10 on a 2-way 6H1 with 4 GB RAM. We are considering running TSM 5.3.2 on a 2-way or 4-way 3.0 GHz Xeon with 4 GB RAM. All non-OS I/O would be via GigE network and redundant 2 Gbs fiber. TSM system details: DB: 32 GB @ 83% utilization Log: 5 GB, roll-forward mode Primary data: 16 TB with one copypool (another 16 TB to manage) Nodes: 175 backing up during a 10-hour window Average daily incoming data: ~ 200 GB; may be reduced via deployment of TDP Oracle Disk: 1 TB DAS, 3 TB SAN Tape: LTO-1, DLT8000, 3570XL, four SCSI drives each; libraries will be consolidated Daily copypool updates sent to vault Semi-annual exports in the 2-5 TB range Does that sound like a system that could reasonably be hosted on a modern Windows system? Is a 2-way adequate, or should we get a 4-way? Thanks in advance. Tab Trepagnier TSM Administrator Laitram, L.L.C.
