Re: [ADSM-L] Maximum throughput with Windows 2003

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.
Pat
