RE: Natively supported inexpensive RAID cards
udma raid cards like the highpoint series are very cheap on ebay because so many people think sata is better that they are dumping them. At the same time the drive manufacturers are dumping udma drives because they are thinking the same thing. TLast month for example I just put 2 mirrored 160GB seagates on a highpoint. The seagates were rebated down to about $35 each, and the highpoint was off ebay for about $15. If it's cheap disk storage your looking for, you can't really beat that.

My gut feel is that it will probably be faster, for RAID 5, to do it in hardware. Am I wrong? This is a frequent topic here. Time to Google! The bottom line advice is always the following: match your system to what you will use it for. Given you are willing to buy a motherboard, you've got the maximum number of knobs to adjust. You also seem to have a cost constraint, which usually favors putting money into the base system (processor, memory, on-board components) rather than into a RAID card. For example, I've seen arguments for and against say $400 into a RAID card AND $400 into a base system. Keeping in mind that few applications are processor limited, based on the little data you have provided on what all you are going to use the system for other than for storing mp3, avi, and other media, I'd lean toward software RAID and putting whatever extra money you have into the base system. You'll also need to play around with things like 4 sata ports on the mboard (easy to find now) being used as 4 striped with no redundancy, 2+2 mirrored, 1 for the system and 3 in a software RAID5, 4 in a software RAID5, and a cheap IDE drive for the system, etc., etc. You also have tunefs, etc. Also, someone might know of RAID5 on the mboard. My recent boards only have RAID 0, 1, and 10.

Abit AW8 / Pentium D and 3ware raid cards compatibility
I posted a few weeks back regarding problems making the aw8 board, work with a 3ware card 7006-2, the system wouldn't boot at all, after much discussion with 3ware they said, sorry nothing we can do, cannot offer an alternative suggested card, so I was about to change the mother board, infact 3ware were unaware of any motherboard which worked with their cards, which also worked with a pentiumD chip, which to be honest I wasn't very impressed with since pentiumD isn't that exotic technology. however ABIT have now issued 1.3 bios for the motherboard, (I had looked on the site an installed 1.2 already ), With this it works fine, the only issue I had were some acpi errors, so I disabled acpi, since it is a server this doesn't seem to be too much of an issue to me, the machine seems to run significantly faster than the old pentium2.8single core, it is difficult to asses the value for money of the machine, although the pentiumD is a similar price to the normal pentiums, the mother boards are significantly more expensive, however if you just want good performance and you don't mind spending a hundred pounds or so more, I would say its definitely worth it, I hope this is of some help to other users, if you would like clarification on anything, I am happy to give more info, kind regards, Gerald ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
recommended raid cards with freebsd support,
Hi, I have a problem, we have been using the 3ware raid cards which mike put me on to and they have been great, however, I have just built a new machine, abit 8w and pentiumD processor, and all was fine until I put the raid card in, it just hangs with the 3ware message. I have raised it with 3ware, and they say the board is not tested with that chipset, I have tested the card on another machine, where it works fine. I am not getting the feeling that 3ware are going to be able to resolve this any time soon, So that's the background, given that I already have all this kit, and the parallel 250MB drives, could anyone suggest alternative raid cards that they have good experiences of (and have some gui support in freebsd), so that then I can investigate whether they might work with my current set up ?? thanks in advance for any suggestions, Gerald ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I am not an expert at all, but I believe the following to be true and advantages of true HW raid cards. To add to the above from Dan Nelson. -- HW raid cards reduce the traffic on your PCI bus. One read or write request is issued and one set of data goes over the PCI bus. The card itself worries about talking to the drives and reading or writing the data from the appropriate drives -- even if you are not CPU bound in terms of fully using the complete CPU, if you are busy, the CPU has a queue of things to do and I like to keep the CPU queue as small as possible... For example, busy PHP based sites can queue up lots of processes even if the load does not peg the CPU due to other considerations, we can avoid extraneous context switches and extra CPU stuff -- good HW raid cards will have monitoring SW -- Adaptec, 3ware, and others do. -- simpler interface for the OS. The OS treats it as just another disk and so bugs in the OS (in your disk driver and RAID sw) don't corrupt your data as easily and in fact make you less OS and HW versions dependent, not more. --- Chad Leigh -- Shire.Net LLC Your Web App and Email hosting provider [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Hardware RAID Cards..
Just be careful on what card you choose. Aside from simply making sure there are drivers for it, you also have to check on the little things. Like, oh, being able to non-destructively grow the size of the RAID5 array. I bought a Promise SX6000. I have 3 200GB drives that will be in RAID5. If I wish to add a 4th, it can't add it to the array. I have to destory the array and start over. Like I said, the little things. :\ Also, remember that growfs is your friend.

What cards have people had good luck with in practice? I've been using a Promise FastTrak S150 TX2/plus for close to a couple of years now. It supports two parallel and two serial ATA drives. I bought it to support my parallel ATA drives and then I thought I'd migrate to SATA, but I haven't done so yet. I've got two parallel drives in a RAID1 (mirrored) array. This configuration is discouraged by the manufacturer because the drives have to share a cable and failure on one drive will very likely lock up the system, but that's not really important to me. I'm more worried about hardware failure than uninterrupted uptime. I've been using this setup since FreeBSD version 5.2, and I'm currently running 5.4. The dmesg looks like: atapci0: Promise PDC20371 SATA150 controller port 0x9800-0x987f,0x9400-0x940f,0x9000-0x903f mem 0xfb00-0xfb01,0xfb027000-0xfb027fff i q 22 at device 2.0 on pci2 atapci0: failed: rid 0x20 is memory, requested 4 That little failure at the end has always been there in one form or another.

Adaptec RAID cards
I've got a Supermicro P4 Xeon server with an onboard Adaptec SCSI controller and a 0 channel RAID adapter with one array, plus a 2200S dual channel RAID controller with a second array. FreeBSD 4.9 doesn't find any disks on the system at all. Neither the asr or aac drivers come up during boot. FreeBSD 5.1 does find both sets of disks. If I pull the 2200S and boot FreeBSD 4.9 the asr driver finds the 0 channel controller and array and installs fine. I've tried the 2200S without the 0 channel adapter and neither disk controller driver loads. Any idea why a 2200S would cause the kernel not to see either disk controller in 4.9 but work fine in semi recent versions of 5? In all instances the adapter BIOS loads and works properly. -- Michael Conlen ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: ATA Raid cards
3ware is the way to go in my experience. They work really well under FreeBSD, Windows and Linux. The FreeBSD drivers were originally written by Mike Smith and Paul Saab is now maintaining them. They are not overly fancy in FreeBSD but they do what they are designed to do. I have used them extensively in RAID0, 1 and 10. RAID 5 is slow, but thats more RAID5 than anything. Also RAID 1 seems to be very intelligent about reads, using both drives to give better read performance as compared to the stats with just one drive. Writes on RAID 1 are not penalized at all. ---Mike At 09:42 AM 23/10/2003, Mathieu Arnold wrote: Hi, I'm in a need of such a card, but I can't find out which cards are only doing raid under windows with specific drivers, and which cards are doing real hard raid. -- Mathieu Arnold ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
