Re: FC-SCSI Bridge issues
Hi Eric We had some similar problems while integrating a SAN with StorageNet (Brocade) switches and the Stornet 3200. Problems disapeared after a firmware upgrade of the switch and the bridges. Thanks and have a good day Gaetano Bisaz
Re: FC/ SCSI
We have seen 60MB/sec into a 3590. It is not easy, because disk is SO
SLOW (even stripe sets) when compared to tape with high compression ratios
(4 to 1). Our test was DB2 in a Winterhawk II node in an SP using highly
optimized Shark disk over fibre. The tape drive was on another Winterhawk
II node connected via SP switch. All disk and tape was fibre.

I have tested this scenario moving to scsi connected 3590e's and fc
connected 3590e's. Using scsi to got about 20Mb/s and fc about 25Mb/s.
I'm
using hardware compressions. I haven't been able to get the high levels
of
throughput the IBM claims you can get from moving to fc. Although I
haven't
tried testing using the move data command yet. My test were coming from
my
disk pool to tape.

Hi everybody
has anyone some experience with this environment.
TSM Server Version 4.1.3 OS=AIX 4.3.3 ML8
3494 Library 4 Tapes 3590E
2 Tapes with SCSI 2 Tapes FC
IBM says the 3590E a much more faster with the FC adapter. So we want to
put one FC Card into our SP and test it.
Then the TSM server should run with SCSI and FC tapes. Later will
upgrade
the next two drives and move the TSM SERVER to a new Hardware.
Mit freundlichen Grüßen

Re: FC/ SCSI
Even though you're using a bigger pipe to get to the drives, you're still limited to the speed the drive can read/write data to the heads.
