I tried this about 2 - 3 months ago and had problems whenever more than
two cards were in my system, even if only a single drive was installed.
I posted about it here (search for multiple promise sata150 tx4
cards back in January).
The symptoms were ata timeouts:
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x0c { DriveStatusError }
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x0c { DriveStatusError }
ata2: status=0x51 { DriveReady SeekComplete Error }
ata2: error=0x0c { DriveStatusError }
ata2: status=0x51 { DriveReady SeekComplete Error }
ata2: error=0x0c { DriveStatusError }
This would happen consistently with three controllers in, never with
two. I tried every possible combination of controllers and drives I
could think of, to eliminate any potential of broken hardware being the
cause.
I should probably give it another go, given there have been a couple of
minor kernel versions since then, but I'm surprised to hear you've had
it working for so long - no-one was able to give me a solution to my
problem at the time (I ended up getting a pair of two-channel SATA
cards) and I assumed it was a driver bug of some description. Promise,
of course, were useless, saying more than a single controller was an
unsupported configuration.
I have 11 drives in one box (on promise.. 2 on the on-board VIA and 1 on
PATA) and 15 drives in another (all across 4 promise cards).. all on
SATA150-TX4 cards..
Performance sucks.. but then when you put 15 drives on a single PCI
33Mhz bus what do you expect ?
Great for streaming media though.. (and cheap, and very reliable). The
only media errors I get are on the VIA controller. The promise
controllers have not had a single media error since they were installed.
I have no complaints about the performance (relatively speaking, of
course), but I've got the cards in a machine with multiple PCI-X busses,
so it's not really bottlenecked there.

I have no complaints about the performance (relatively speaking, of course), but I've got the cards in a machine with multiple PCI-X busses, so it's not really bottlenecked there. Perhaps its related to that. All mine are on ASUS A7V600 motherboards with a single bog standard PCI bus. At one point early on I recall someone stating they were having all sorts of problems with those cards and a 66Mhz bus.. Are you running the latest BIOS in all the cards? Only ask as the 1st thing I did when mine arrived was to upgrade the BIOS.. not using it but I thought it might have some impact on the way they are set up on the PCI bus. I have a mate who has another 3 in his box also.. but again he's on an ASUS A7V600 motherboard. I'm looking to build another 15 drive box soon and I was thinking of perhaps a couple of 8 port Marvell cards, but then I might just stick with what I know and source some more of the same.

Re[2]: Recommendations for supported 4-port SATA PCI card ?
Hello Joshua, JBL That's exactly why I recommended them. 3w- has been in the kernel a JBL *long* time and is extremely stable. Sure, it's expensive for just a JBL SATA controller, but not for a solid one that doesn't fall over at random JBL times. Just for my 2 cents: we have a number of different generations of 3Ware cards (IDE and SATA) in our campus network, mostly with Western Digital drives. It seems quite beneficial to use their Raid Edition series of drives instead of desktop ones. Beside the longer warranty and perhaps better manufacturing and better resistance to vibration, according to the WD site, these drives also report errors (if any) quicker to a host adapter. This results in errors being handled by RAID hardware gracefully, instead of the whole drive being considered as timed out. In practice, we had some fun months with a RAID5 set made of desktop Caviars rebuilding once in a while for no apparent reason, with each disk working well for a long time. And we had no such problem with RE disks for over a year now. Hope this helps some list readers make their choice, and please don't consider this an advertisement of certain brands ;) If any other manufaturer offers capabilities similar to WD RE (especially timeouts), please take a better look if you consider a hardware RAID controller. -- Best regards, Jim Klimovmailto:[EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe linux-raid in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: Recommendations for supported 4-port SATA PCI card ?
http://linuxmafia.com/faq/Hardware/sata.html A little bit outdated though. (Amazing how many RAID cards are fakeraid) well, the page is useful in that it discusses particular products, but the fakeraid stuff is just silly name-calling. there are either real (hardware) raid cards, and there are multiport cards. fakeraid just means that there is code in the bios to do software raid 0/1 - not a bad thing in any possible sense, though also of zero value to many people. the prevalence of fakeraid simply shows that to be worth doing, hw raid requires a pretty hefty piece of hardware, like the 3ware 9550. older boards that had, for instance, a single pc100 dimm on them were the kiss of death, since just seeing that you knew that they couldn't move more than 10-20 MB/s, much less than a single disk's worth. - To unsubscribe from this list: send the line unsubscribe linux-raid in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: Recommendations for supported 4-port SATA PCI card ?
Addonics adst114 was the cheapest one I've found that works. I found it for $41 at thenerds.net but you may be better at the price searching than me. It's a Silicon Images 3114 chip, driven by the sata_sil driver I honestly don't recall if it was out-of-the-box working on FC4, but the updated kernels drive it fine, and FC5 (with 2.6.16+) should be fine with it. -Mike Ian Thurlbeck wrote: Dear All I have 4x500GB Maxtor SATA drives and I want to attach these to a 4-port SATA PCI card and RAID5 them using md Could anybody recommend a card that will have out of box support on a Fedora system ?
