Title: SCSI Throughput Question

I have a ESA10000 disk cabinet with 2-HSZ70 controllers (dual-redundant), feeding into a KZPBA on a ES40.

I have run diskx and fsx and have noticed that pretty much regardless of RAID/BUS configurations (I tried RAID0,RAID1, RAID5, RAID0+1, I see about 15MB/s max going through the HSZ70's (confirmed by viewing vtdpy).

I thought KZPBA's were capable of 40MB/s, and the new 70's could do 36MB/s. Obviously my numbers are wrong - does anybody have accurate real benchmark numbers for this configuration?

Thanks.
