inexpensive SCSI RAID hardware

Post by Yan Seine » Fri, 06 Aug 1999 04:00:00



I was fishing around pricewatch and found 9 GB SCSI micropolis 3391WS
SCSI3 disks and a mylex KT950 SCSI3 controller.  Five disks and the
controller add up to less than $1,200 - a great price for RAID-5 of
36GB.

Is this hardware worth it?  Does the controller rely on the CPU for all
processing?   I have one of the idiot SCSI mylex controllers in my
server now, and I think the CPU (a p5-166) can't keep up with it.

I have never done any SCSI raid arrays.  Any advice is greatly
appreciated.

TIA

Yan

micropolis is bancrupt - so you cannot count on any guarantees probably.

try in comp.periphs.scsi and mention why you need it and what you expect
from it. IIRC micropolis has an extremely bad name, so that you'd *need*
the raid5 to get some reliable storage - which is not the idea at all.

I see some ibm DNES 18 Gb drives for around $650 here and I wonder if 2
of them wouldn't be faster and more reliable....

1. SCSI board with hardware RAID?

I am looking for a SCSI board for the S-bus which provides
RAID functionality in hardware.  The card that I have in mind
would be similar to the DPT SmartCache and SmartRAID, except
that those cards are for PC ([E]ISA + PCI) buses.

Any suggestions, tips, pointers, etc. are very much appreciated.

Regards,
