Where are you getting this throughput - LAN or SAN? LAN-free storage agent transfer relatively small ammounts of metadata over LAN and you cannot achive best possible peak rates there. For LAN data transfer you should be able to achieve at least 7-8 MB/s so the problem could be with TCP/IP settings not Named Pipes. SAN throughput is limited by both tape drive and the application providing the data stream. For filesystems this is the storage agent itself. But what is the tape drive you are writting to and isn't it the bottleneck (LTO can be too fast and constantly lose streaming)? Are you using client or tape compression?

We're running the latest 4.2.x TSM B/A client on a Win2K box running LAN-free to a Sun Microsystems Sunfire backup server (TSM 4.2.1.7). We've noticed that using NamedPipe between the TSM Storage Agent and the TSM backup server is almost twice as fast as traditional IP based but we're only able to get about 3 - 4MB/s throughput. Are there any settings pertaining to NamedPipe we can use?
