I can do this, I want to put a 16Meg SIMM in there (on the ICP card) first.
Right now I have a 4Meg one in there and that is too small.
I've heard that the new December firmware they are working on is better.
For me, the big sell with the card was that it natively supports Linux. I
can fire up gdtmon right now in an X window and check the drive stats,
quiet the bus to bring a hot spare online, view cache stats. And the
support guy here in the states (Andreas) rocks. Very helpful. I've had a
drive fail and the hot spare kicked in, worked great.
If it had SNMP support for traps so I didn't have to troll through the log
for messages that would be heaven. The single channel card costs around
$950 or so.
I've already bought several of the cards and will have a new RAID 5 FW
external system with 4 9Gig Cheetah 10K RPM drives online in a couple weeks.
