Mylex RAID Performance

[Nigel Weeks]

Has anyone got more than about 5MB/sec out of a Mylex DAC960PD?

I have two striped 7200RPM 68-pin wide ultra drives on a channel
(each channel supposed to handle 40MB/sec)

Having one drive on each channel made no difference.

Running the following command resulted in 5MB/sec maximum throughput

dd if=/dev/zero of=/u1/hog bs=1024 count=5000

I tried this of block sizes (bs parameter) of 1024, 2048, 4096, 8192, 16000,
and 32000

Any ideas?

Nige.
