I agree with that up to a point. "I/O, I/O, it's all about I/O" --- me
The majority of my customers have Windows TSM servers - precisely because there are more small/medium sites in the world than large ones. TSM on Windows is very stable and very effective. The only problem I have with it is the hardware. Only the very largest Windows servers have enough HBA slots to support more than about 4 tape drives (if you want to have bandwidth to really run LTO3 or LTO4 or 3592.) And adding HBA's to a Windows box doesn't necessarily give you more throughput. And there is NO instrumentation in Windows to give you any idea whatever about what is going on performance-wise on a bus with tape drives attached. My Windows customers that have LTO3 and LTO4 attached get great capacity, but don't come anywhere near pushing the drives at full speed. AIX on P-series hardware, on the other hand, is a screaming I/O machine. You can push amazing amounts of data through one. So in general (and this is just based on my experience with my customers and YMMV): -if you have a site that is pushing 2 TB of data per day or less, it will work fine on Windows, you won't have to tune anything, it will just run. -If you have a site that needs to push more than 5-6 TB of data per day, for sure stick with AIX. In between, you have to plan your hardware config CAREFULLY and think a lot about architecture before going to a Windows TSM server.
