Hello, list. We are speculating whether we should employ the latest CMT-server from SUN as TSM-servers. The CMT-servers are many cores/many threads but each thread is relatively slow(1,2/1,4 GHz) compared to Ultra Sparc(2,3Ghz). My question is if TSM benefits from many threads or if we should go for single thread performance. I guess expiration is a single thread process but that depends mainly on IO. Maybe many simultanious client operations would benefit from many threads. How about TSM version 6?
Current TSM server releases are heavily multithreaded, so more cpu cores are quite useful, but keep in mind that TSM is about I/O more than about CPU, so your main concern when selecting hardware should be the I/O bandwidth. How many PCI buses does your system have, do they share logic? In case of PCIe, things usually get a lot hazier... how much bandwidth do the PCIe controllers have each to your memory etc....
