What is a good choice of sata-ii raid controller for freebsd?
Hello! I need a raid controller for FBSD 6.2 which has the following options 1) Full SATA-II support 2) Good rperfomance (over 50MB read, over 30 write) in mirror mode 3) No weird problems with freebSD (like with SRCS16) 4) Utility to monitor status of raids (command line or web) 5) Utility to rebuild, repair, manager arrays in OS 6) Preferably Intel I know, 3ware has such good stuff, but those controller are not certified for internet services in here (russia). So, i am pretty much limited to Intel controllers. Is there intel controller which satisfied all the 1-6 conditions? I only need mirroring. -- С уважением, Артем Кучин ООО Ай Ти Легион www.itlegion.ru +7 (495) 232-0338 ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Ultimately this turns me off to using any form of RAID controller; vendors who refuse to give full documentation for their hardware to engineers who want to write drivers for it, refuse to implement proper passthrough methods (I'm looking at you, Adaptec) so that you can talk to the drives directly if need be, nor provide you with any form of useful FreeBSD support (here's our old crusty 3.x a.out binaries built by a guy who left the company 7 years ago! Thanks for buying company, bye!) The best out of the bunch in this regards seems to be Promise, who despite having ehhh controllers, has given Soren lots of documen- tation and has been helpful in providing him answers to his questions. I can't say the same for other controller vendors. I'm sorry if I sound bitter, but I must have gone through 4 different brands of SATA RAID controllers before saying screw this and going with non-RAID or using geom.

We ran the test server for three weeks with one drive disconnected. Couldn't really notice any performance lags in normal use (it was a mail filtering gateway box running Postfix, MySQL, Amavisd-new, and ClamAV). When we plugged the drive back in, a message was logged (and send via e-mail) that a new drive was found, and a rebuild was underway. Took three or four days to rebuild the array during normal usage, and performance did take a hit during this time. After the rebuild completed, another message was logged and an e-mail sent saying everything was back to normal. 3) Does Areca provide any form of carriage/enclosure medium, such as an enclosure which supports 4 drives, allows hot-swapping, and allows you to query the enclosure for statistics (fan RPM, thermals, and so on)?

RE: What is a good choice of sata-ii raid controller for freebsd?
They kick ass is what they are like. :) I had a 3U box with a 12 port controller sitting next to my desk for a few weeks and my only goal was to confuse/break the 3Ware controller. No amount of power plug pulling, pulling multiple drives, quickly re-arranging drives could confuse the controller. Made the SCSI stuff we use look like absolute neurotic junk. Forgot that note - Areca handles drive location changes the same way. I assume this is handled by metadata on the drive. -They added a moving part (2-wire fan, no tach) to a mission-critical part. That seems real stupid. After the bearings die in 2-3 years, what happens to your card? Does it melt or just start acting weird? If the engineers didn't consider that, what other failure modes did their limited creativity miss? :) Strange. Our 1160 has a fan, but also had just a heatsink (no fan) that was in the box. My 1261ML was heatsink only. I believe someone asked for the feature. Both controllers monitor the fan and would notify you if the fan died. You can turn the option on or off (off by default) if you need to. -Availability. None of our normal dealers could get them. Availability seems to be a bit better now, but I can't answer for your dealers. -Not many people seemed to be using them, so less feedback available and the whole package (hardware/firmware/driver) has less exposure than 3Ware. While the 9xxx series seem to be great (use a different driver), the twe cards caused me so much grief that I was afraid to try them out. We had a bunch of corruption issues (in RAID 5) with our 75xx controllers that I was never able to fix. RAID 0 or 1 seems to work just fine for them. -3Ware answered pre-sales questions, Areca didn't. Perhaps they've changed? I spent a good hour on the phone with a tech before we purchased our first controller. This was last year sometime. Performance and feature-wise the Areca and 3Ware seemed pretty close, so we went with 3Ware. Everyone has their reasons - I liked the RAID 6 feature, plus the OOB management of Areca, plus my history with 3ware wasn't good. :( Jaime Bozza Qlinks Media Group ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
RE: What is a good choice of sata-ii raid controller for freebsd?
I want to second the recommendation for Areca controllers. We have two systems - The first is using an 1160 (16-port PCI-x) with 16 400GB drives, the 2nd is using the newer 1261ML card (16 port PCI Express, mini SAS connectors) with 16 500GB drives. Comments below: 1) Do these controllers, from a BIOS level, permit SMART commands to be sent directly to the drives (via pass(4)) so you can monitor drives for potential upcoming failures and perform drive tests, via smartctl? The cli32 will give you smart attributes, but no testing when the drive is part of a RaidSet. The controllers do support passthrough with JBOD. See below for more information. 2) Regardless of performance, have you actually tried a hard failure with these controllers and seen what both the controller and the OS do? A good example is to pull the SATA power plug out of one of the drives in the array while it's powered on and see what happens, both from a controller perspective and what FreeBSD does. The same question applies to hot-swapping. Both our systems are using RAID 6, and I've tested them thoroughly. I've pulled one drive out, OS didn't really care. The 16-port cards have their own Ethernet interface which will send emails for any events. Put the drive back in and the controllers just automatically start rebuilding. While I was rebuilding, I pulled a different drive. Again - FreeBSD happily went on. Put the drive back in and the controllers would rebuild the 2nd drive after done with the first. During all this, FreeBSD could do anything it wanted with the array. I then dropped power to the entire system. Coming back on, it would start rebuilding once FreeBSD started to load (the controller needs to have an OS Driver loaded before it starts to rebuild, or you need to go into the BIOS utility to process the rebuild in the foreground). Booting, fsck, or anything else would work just fine while the system was rebuilding. You can set the background processing to be 5%, 20%, 50%, or 80%. Obviously, 80% will be quicker but slow down access to the system. I didn't feel that it slowed down TOO much, but that is a matter of opinion. Setting it to 5% or 20% should have little or no change in performance. 3) Does Areca provide any form of carriage/enclosure medium, such as an enclosure which supports 4 drives, allows hot-swapping, and allows you to query the enclosure for statistics (fan RPM, thermals, and so on)? Areca supports individual HD Activity/Failure connections and the I2C standard. I don't believe Areca has its own external drive cage, but it'll work with many others. I'm not sure about drive cage thermals or fans, but it monitors everything about the drives. We handle case thermals via the motherboard. The controllers we have do not have any external connectors, so it would all be internal. 4) string'ing the cli32 binary returns some references to SMART, but the monitoring is generally retarded (literally, not slang) -- it looks as if it just wants to use SMART to say drive bad or drive good. This is not an effective use of SMART, and does nothing for those wanting to monitor drives properly (read: temperature, excessive ECC, perform SMART tests for bad blocks, etc.). In RAID mode, I don't think it allows you to test each drive directly. It'll monitor the SMART attributes and generate warnings (for instance, if a drive gets too hot), or if there are other problems. If you're looking at using the controller in JBOD mode, or a drive in JBOD mode, you can create a passthrough, which I would assume would allow you direct access, but I haven't tested that. 5) Is there native FreeBSD 6.x binaries for administrative utilities? It doesn't look like it, but maybe I'm looking at the wrong utility: ~/V1.5_50930 $ file cli32 cli32: ELF 32-bit LSB executable, Intel 80386, version 1, for FreeBSD 4.2, statically linked, not stripped While the utility may be 4.2, it's statically linked, so it works fine on any later version (of FreeBSD) I've tested. I'm sorry if I sound bitter, but I must have gone through 4 different brands of SATA RAID controllers before saying screw this and going with non-RAID or using geom. I don't have anything against Areca (I've never used their hardware), but I have no desire to use hardware which does not support the above things -- which in 2007 should be standard by all means. The only thing that the Areca cards may not give you is the ability to run SMART tests on a drive. I think the idea is that Areca just monitors the drive and if the drive reports any sort of stability, it takes the drive offline and notifies you. In a case like that, I would be more inclined to pull the drive, replace it with a new one, and run my tests on the old (possibly bad) drive outside the RAID array. IMHO, I don't want to take chances testing a drive and having the array in a degraded state. Another possibility

Despite not being a fan of the 2410SA, I'm pretty happy with the SCSI version (2120S) which uses the exact same FreeBSD driver. Part of that is the SCSI version has a battery option so write speeds don't suck, where the SATA version doesn't. Or at least that specific model of SATA card doesn't.

Re: pppd crashes, was: kde-freebsd
Ok, now an editorial: Kernel PPP is certified crap and should be phased out. In my personal opinion the reason that it is unmaintained and slowly dissolving into a nonfunctional pool of electrolytes, is that it is functionally obsolete. User PPP provides better service, and several tangible design benefits. User PPP is very easy to use, Kernel PPP is not. I have had nothing but serious problems with Kernel PPP, In my experience whenever Kernel PPP crashes, which it does pretty much at random, and always when the network drops (a common happening for those of us blighted by Dial up.) It causes the whole system to lock up. *Forcing*me*to*physically*unplug*the*computer*to*continue*. FreeBSD is NOT Linux, and SHOULD NOT attempt to model it. FreeBSD is BSD UNIX! Isn't that the WHOLE POINT (pardon my shouting) for our existence? Isn't this why you and me bear with minor points such as this one. BECAUSE WE ARE DIFFERENT AND PROUD OF IT! If you just start modeling Linux, we are invalidating our own existence and vindicating Linux's innumerable disparities, nay flaws. We have a fundamental design difference from Linux here. We chose this difference because we believed that it was better. Why would we go back now because the developers of a third-party interface to our systems did a clumsy job? Rather than weep in anguish at their implementation of a known faulty and legacy system. We should adjure them to implement the new and better system. This is not actually an appropriate place for this discussion. It should be directed to [EMAIL PROTECTED] and/or http://bugs.kde.org. Because it is a KDE problem and *not* a FreeBSD Problem.

Even though the 9500s are listed as 1.5G SATA parts, you'll never get better than ATA-133 speeds out of them. Which is quite irrelevant since there are no SATA-disks which actually can use more speed than that. (The fastest SATA-disks currently available -- Western Digital's Raptor series has a maximum transfer rate of just under 90 MB/s. Most disks are significantly slower than that.) The 133 MB/s one can get out of ATA-133 is quite enough for that (and not all that much less than the 150MB/s that normal SATA provides. (Some SATA devices also provide a 300MB/s transfer speed, but since no disks can keep up with that it does not make all that much of a difference in practice.)) Just about all reviews that have compared both controllers and disks with and without SATA-PATA bridges have come to the conclusion that those bridges do not cause any measurable drop in performance over their native-SATA counterparts. The only real drawback with using SATA-PATA bridges is that you cannot get support for the optional SATA features like NCQ. (But not all native-SATA solutions support those features either.) We didn't realise that when we ordered our first pair of Escalade 9500S 4-port cards. Thankfully, just after they arrived and before we put in the mass-order, the 9550SX was released and we've standardised on them. The 9550SX should be a bit faster than the 9500S and the 9650SE faster still, but that is for other reasons. (Faster processor for handling the parity calculations for RAID-5, faster memory on the card, being able to do more operations in parallell, etc.) -- Insert your favourite quote here.

The updated 3dm2 for it did make it into the Ports tree. I noticed that when I was making my reply from earlier. At some point in time I may test out the newer (twa-based) cards. It seems that 3ware is actually interested in supporting those. They never managed to get the twe driver out of what they called beta, so that's where my experience ended. Interesting thing - When I installed FreeBSD on the new system (pre-6.2 version discs) it didn't see the new Areca card. I started to get worried but quickly found out that the driver had been updated shortly before 6.2 was released. Quick update and all was well. So the kernel driver *is* being updated. Driver annoyances aside, my 9650SE is considerably faster than my 9500S (both have batteries, both have the drive's write cache off), especially on writes, and they are both much faster than my Adaptec 2410SA (which has no battery option and thus needed write caching disabled). I haven't tested the current system in speeds, but it's noticeably faster than my other (1160 PCI-X) system. Possibly due to the fact that I was using WD4000YR drives in the first which do not support the updated speeds of SATA2. The current system does and the card detects it. The newer card also has an updated processor - Intel IOP341 instead of an IOP33x series processor which I would guess makes a big difference. At least according to synthetic benchmarks going around the net. :) I've never tried Areca. I would probably like them, from the sound of things. I'm sticking with 3Ware for SATA systems for now though... but hey, personal preference and all. For my next SCSI/SAS system I may have to do some serious evaluation of what's new out there... Regardless of what you choose, there are a few decent options for FreeBSD now. Shows that people out there are actually starting to care about FreeBSD for some of these controllers. Unfortunately, I didn't have the same solid results with the mirroring (RAID1) support for onboard SATA (Supermicro X7DVL-E). I mirrored two SATA2 drives (OS) and tried pulling one drive. Placing it back in didn't automatically start a rebuild, but I could force it. Pulling it, restarting, and then removing the drive from the RAID1 array (via the BIOS) would then cause FreeBSD to panic at boot (or drive insertion) every time. I don't know if it was the fact that there was still metadata on the drive so the ataraid driver thought something differently, but it bothered me a little. I had to disable ATA RAID in the BIOS completely (and remove the ataraid device from the kernel) to get FreeBSD to boot or allow the drive back into the system at all. Since the motherboard RAID is just software RAID, I switched over to gmirror but kept AHCI on so I'd still have hotplug support. After that I wasn't able to kill the system.

The best info I could find at the time about the fan was looking at the picture on their website - it showed a small heatsink+fan with two wires (no tach). I'm certainly not trying to push people away from the Areca cards - the more FreeBSD people out there using these the better. Next time we may buy some Arecas since I now am finding some positive feedback from the FreeBSD community.
