fastt200 write speed
|
|
|
| Hi all
I am trying to restore a single file over our SAN to a win2k server
using TSM. This server has two fibre direct connections to a fastt200.
The file is 440Gb, the volume presented to the win2k server is 536Gb
(RAID5).
I've tried various segment sizes with FASTT storage manager and
various allocation unit sizes within windows. Read and write cache on
the fastt is enabled.
No matter what I try I cannot get write speeds of >9Mb/sec. This is
the same when restoring the large file from TSM or copying a 5Gb file
from the local c:
Can anyone out there tell me what write speeds they have managed on
their FastT200s RAID5.? What should the FASTT200 be able to write at?
Cheers
Chris

| What type of server is TSM on? Is it AIX?
