Don- too bad- I'm over in NAS in building N-258 and just took down the h/w where we could test this (Alpha 4100 with 8 Qlogic cards && 8 150GB MegaDrive RAID arrays)- We're excessing this equipment because the mass storage group's work was terminated due to budgetary goop. Typically there's no problem in *recognizing* raw SCSI disk, or RAID units that look like a SCSI disks- Mike or others will have to speak about how well specifical supported RAID cards for FreeBSD will handle something that large. A more problematic issue is whether FFS can reliably handle > 1TB. We did some tests with NetBSD at 1TB a couple of years ago- you have to use larger block and frag sizes (we were using 32k/8k)- but I've never myelf gotten FreeBSD up above 500GB. I was going to do so when the rather flakey h/w I was on above was set to be excessed. If I'd known you needed the work done- I could have kept it going a couple more weeks and we could worked on sorting it out. -matt On Sat, 15 Sep 2001, Don Sullivan wrote: > > I probably SHOULD know this, but how can I get a 1.3 TB > RAID 5 array recognized by FBD 4.3 (Or, 4.4 RC5) ? > > Thanks for reading this, > Don > ----------------------------------------------- > Don Sullivan > NASA Ames Research Center > MS 242-4 > Moffett Field, CA 94035-1000 > Office: +1.650.604.0526 > Lab: +1.650.604.0595 (best bet) > Fax: +1.650.604.4680 > email: dsullivan@gaia.arc.nasa.gov > ----------------------------------------------- > > Never argue with an idiot; > They drag you down to their level, > and then beat you with experience. > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-hackers" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
