I'm connecting a Infortrend SCSI Raid (supporting LVD, Ultra SCSI3, etc
and performing well under Linux) to a F50 with an Dual Channel Ultra3
SCSI Adapter (which should archive up to 160 MB/sec).
Reading 100MB of the same 64k block from the raid (it has 256 MB of
cache) showes me the SCSI Performance of the bus.
It takes about 4 seconds reading from /dev/rhdiskX, which is 25MB/sec.
Looking at the raid it tells me, that AIX is talking async narrow to the
Does anybody have experiance connecting a non IBM RAID on Ultra SCSI3 to
an AIX machine?
I would expect transfer rates at least of 60 MB reading from cache.
Perhaps there is a need for ODM config changes to tell AIX that osdisk
is a LVD disk?
Thanks in advance,
