Hi James and the others using Dell and FBSD, I have had terrible problems with the perc controllers from Dell that have been discussed before on this list. However we order our 2400's and 1400's from dell and add Adaptec's 2100S and 3200S controllers that Mike Smith added support for in 4.2 and the hardware RAID is the fastest reliable RAID we have ever seen. The only difficulty is find the "raidutil" and storage manager software for FreeBSD. They don't provide source, but with enough digging I found the executables. Haven't had much luck with storage manager but raidutil works just great from the command line. Here is a link for the products: http://www.adaptec.com/worldwide/product/prodtechindex.html?cat=/Techn ology/RAID Hope this helps others on Dell, it would be great to get Dell to offers these controllers instead of those crappy PERC controllers, but these I guess are too expensive??? Hope this helps other freebsd-stable users, Ken ----- Original Message ----- From: "James Satterfield" <jsatterfield@intertrust.com> To: <stable@FreeBSD.ORG> Sent: Tuesday, July 31, 2001 2:39 PM Subject: RE: PERC 3 Dell 2500 and FreeBSD 4.3 stable > # Begin rambling > The Perc 3QC is an AMI Enterprise 1600 card.
