James We use Shark internally, connected to AIX, Solaris and Windows servers. Much better than Hitachi IMO. The caching mechanism is similar to EMC, and the IO performance is excellent, even with RAID5. Actually I am told it is RAID-S, but it is all a black box to me. I just know that my DSS DW DB's load faster with the Shark than they do with ordinary raw volumes on SCSI. HTH.

What is you're opinion? I understand it uses raid 5 :-( with a big cache in front. I've talked to a couple of DBA's that are using them and they think they are great and haven't experienced any problems with poor performance (including write speed). We've had a bad experience with Hitachi raid 5, salesman said it was great so the boss bought it.
