Also don't forget the Intel SRCS14. http://developer.intel.com/design/servers/buildingblocks/srcs14l/ -Sam -----Original Message----- From: owner-freebsd-hardware@freebsd.org [mailto:owner-freebsd-hardware@freebsd.org] On Behalf Of Artem Koutchine Sent: Wednesday, February 25, 2004 2:40 AM To: freebsd-hardware@freebsd.org Subject: Choosing Serial ATA RAID 5 controller for FBSD 4.9 We are trying to build a havy load web 2U server using Serial ATA RAID 5 controller. The server will run FreeBSD 4.9 and we need a raid card which is supported by 4.9. Another 'must' for the card is that it must be a real hardware RAID 5. Other 'musts' - the card must be LP (low prifile pci card), support PCI 64bit, be real SATA, not just a bridge. Also, it should have nice cache size. For far there are only two candidates: 1) 3Ware 8506-4 2) Adaptec 2410SA IFAIK there are people running FBSD 4.9 on 3Ware 8506-4, however, W3ware 8xxx card are not listed in the supported hardware for 4.9-RELEASE. Is it just a mistake or it is really not supported or not fully supported? Also, 3Ware 85xx oficially does not have any cache, however, i have found somewhere that it does have it and the cache is 2MB, which is puny. Is it a big deal? Does it really affect perfomance (the card will be running at least 3 drives each with 4-8MB of cache on its own). Adaptec 2410SA seems to be just perfect. Real hardware, 64MB Cache, raid level migration, auto rebuilding and other features. However, i have only some one person running it on 5.2. Can it be run on 4.9? How stable are the drivers? What is better - stay with 4.9 and 3ware or try using 5.2 in production environment with Adaptec? The server will go in production by the end of april 2004, maybe 5.2 will be stable enough by then to run it in production? Any thoughts and comments will be apriciated.
