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. --WjW -- Internet Access Eindhoven BV., voice: +31-40-2 393 393, data: +31-40-2 606 606 P.O. 928, 5600 AX Eindhoven, The Netherlands Full Internet connectivity for only fl 12.95 a month.
