Hi Ian, Great information...
I had no idea Windows 2003 could get read speeds of 400MB/s. My proposed VTL does not do de-dupe in line, it is a post process so I am not concerned with VTL performance. I need to backup about 10 TB's from the array. This is a mix of file system, email and database... I will be using BCV's and mounting those volumes on Win 2003 hosts. I am not sure how much impact TSM has on moving data? I have a choice. I can use VTL or add more physical LTO-3 drives... I understand the benefits of a VTL in a TSM environment, but more specifically... LTO-3 can do 80MB/sec. If I have 4 drives allocated to Windows host, I don't think I can keep them streaming? Will I be better off with 8 virtual drives? Will more streams give me more performance with TSM? I am new to TSM, I know it does not do multiplexing but not sure about multistreaming? Am I better off creating multiple BCV's and mounting different file systems in order to have more streams or should I keep it simple and have larger luns with only a single stream? Thanks again for the help.
