Truth is, whether you, I, or anyone likes it – these shelves of disk that are installed by major array vendors sometimes many racks’ worth are usually supplied through a single disk vendor’s run of disks from a particular batch. Discussion in ‘ Hardware ‘ started by dave 58ghz. Or look for the ZFS references to it. So I tried a couple of things, got some advice and learned some things. According to the technical support, hot spare designated disks will spin although not being used. But seriously, now, my point is to avoid giving people advice that’s commonly understood to be bad. While it is very unlikely that a user who has a small quantity of drives in RAIDZ2 will lose enough drives to render the pool useless, the fact of the matter is that you can reduce that risk further through careful selection of hardware.

Have you updated all the firmware for your system?
3ware S-4LP Specs – CNET
3wxre, when you purchase an enterprise array and you allow the vendor to define what gets put into it, that’s what you get. I’d like to end up around 10TB. I don’t have a to test with. I wouldn’t build a software array from disks connected to various controllers.
Post as a guest Name. So, I configured the 3ware card for hardware raid 5, TB.
But out of the population of arrays that are made out of Barracudas, 3wars are likely to have an artificially high rate of data loss, because some sets of drives are statistically more prone to fail. But I’m going to advise people that this is risky, and I’m certainly going to speak up when someone actually suggests it as though it’s a best practice.
Anyways, it’s kind of unfortunate because the writeback cache on these would be nice for a little ZFS acceleration, but you’ll probably be delighted even using just a plain SATA controller. When I discuss with my customers how their arrays have been operating 95000s year to 3 years after the initial install, they have always reported that only a disk or two has failed.
If this year’s Barracuda has some bad runs, your array built out of WD Black’s isn’t going to be more unreliable because of it. Wow, makes me feel old. I suppose you hadn’t noticed that they also push really heavily for you to buy backup systems and second sets of storage and all sorts of things if you want “additional reliability.
Thanks, but no, I’d never end up doing anything meaningful with it, even if I could dig up appropriate cabling. Now, if you’re small, they may simply choose to ignore your business if you insist on heterogeneous storage.
I have a gigabyte m68mt-2sp motherboard with an AMD phenom x2 3.

Or perhaps I’m uninformed, Network Appliance’s uninformed, Google’s uninformed, FreeNAS users are uninformed, and you’re here to enlighten us as to how our ways are stupid and we’re wrong to buy a mix of drives so that it’s easier for us to.
When you get that far, that is. I just checked, and I’m running the latest motherboard bios version. Maybe it could be worth it to leave the disk unplugged, powering it only when alarms are given. May 29, Messages: I’m guessing will cause some problems later on down the road? But I don’t get paid to sit on my rear and take it easy. Your name or email address: The ‘s used to work really nicely with FreeBSD.
This is not the age of SCSI busses where you had incompatible firmware on different drives on the same bus and you’d get lockups if you mixed them. Maybe, if you find yourself on the side of being wrong. Personally, I think you’re taking a rather statistically improbable scenario and blowing it way out of proportion to sound as though you’re more informed than you actually are.
