Hi,

Might be a beter question on scsi-freebsd??

I'm using one at home at testsystem to be used at work. We would then go
for enhance availability on most systems (RAID-5). And large disks for
our news server (RAID-0)

Haven't had problems with it as long as I didn't start experimenting.

I have the DPT3334UW with 32 Mb RAM, running firmware 7L0.
Normally it works with 4*2Gb narrow disks:
	3 for raid 5, 1 hotswap.
It's is a seperate shoebox with 4 feet of narrow cable.
The DPT makes a narrow outlet with a wide->narrow converter (comes with the
controller) into a rear-bracket with sub-db 50 connector.

Currenlty is also has 7 4Gb-UW, IBM's connected to do some extra testing.
But that seems to hang the chain once in a while. But then I have the same
trouble hanging the 7 disks from a 2940UW.

I've been trying to grasp the problem with the help of Simon Shapiro.

Probably it'll boil down to to cheap-a-hardware, cabinet, cables, ....

My major problem is the lack of tools to monitor/control the RAID from
FreeBSD. You'd have to go back into DOS mode to do just that, and that's
against our goal: availability.

So in general I have a good feeling about this system. Unless it starts
to hickup, then it takes a little more time.

Simon's personal support is really great.
