I have been given the task of implementing a raid configuration that will utilize these drives. I have looked at the following companies, cmd, mylex, infotrend, and chaparell. I narrowed down the search to infotrend and chaparell because they offer ultra2 wide to ultra2 wide, 80Mb/s transfer. I contacted a reseller of the chaparell line and he informed me that none of the external scsi to scsi raid controlers that he had seen, offered the full through put, save the chapparel model 5412. I was wondering if anyone else had found this to be the case. I like the infotrend sentinelRAID 1000 as it allows an upgrade path for redundant controlers. If anyone has a second would you respond with any advise (or experiences) concerning a ultra2 wide to ultra2 wide external RAID controler. IE, what do you use, did you run in to a great many problems, do you get the performance you thought you would? Any help would be greatly apreciated. Also if SCSI was the wrong list to mail to I am very sorry. H. J.
