To: stable@FreeBSD.ORG Date: Thu, 29 Oct 1998 14:52:18 -0600 (CST) X-Mailer: ELM [version 2.4 PL23] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I'm new to this raid stuff. I understand you can get a raid which hooks to the scsi bus and looks to the computer like an ordinary (albeit fast) disk. Theoretically this would work without any specific OS support, right? The alternative would be a raid card on the PCI bus, which can move data faster, but would require OS driver support. Of course there's a lot to be said for OS-independent hardware, but aside from the faster speed, are there worthwhile advantages (i.e. access to special features) to be gained by going with a PCI raid card? I understand fbsd supports DPT pci controllers. How do they compare with the competition? The machine would be a 400mhz xeon, a departmental server, with an adaptec 2940 ultra wide/fast controller. Sorry for the open-ended questions, any faq pointers would be much appreciated. Thanks for any help!!!
