What cable do I need for this scsi array?

Energize · 25 Aug 2008 at 21:01

I've bought 6 15k 18.6gb hp scsi drives, an ultra 320 raid card (ofc I'll be limited to pci's 266MB/s) and 80pin to 68pin adaptors off the bay, the only thing I need now is the cables for them, what type of cable do I need to connect them all to the controller card?

Don't get much response to scsi questions in the hdd forum, so I've posted in here instead.

You'll need a SCSI Wide cable.

So do I just need an 8 way cable and a terminator on the end?

Correct. An 8 way LVD SCSI cable with a terminator is all you'll need.

Thanks.

If the card and cable are Ultra 320 but the drives are Ultra 160, does that limit the raid 0 array to 160MB/s, or will I still be able to get 266MB/s? I bought a 320 card for upgrades in the future but would be nice if I can get near the max pci 2.2 bandwidth using the current drives even though I bought scsi primarily for the access times.

And can anyone tell my why there is loads of one to one cables everywhere? What's the point in buying scsi and then connecting one hard drive to the controller? :confused:

Either tape connection, or connecting a hot-swap enclosure I'd guess from what I've seen, I've only really gotten into servers and stuff since SAS came on the scene.

Hmm, my controller card now detects all the drives, but can only retrieve the specs of the first drive so can't raid anything yet.
