Re: Real-World file server CPU requirements

Does ZFS really have a solution besides dual parity, something you don't need ZFS for?

Re: Real-World file server CPU requirements

Pardon my ignorance, but my take was that read errors can kill the array during the rebuild , not during normal operation. Because all the data on non-failed drives has to be read to reconstruct the failed drive. If an error is reported, all the RAID array needs to do is return errors when attempti...

Re: Real-World file server CPU requirements

OK, opinion... Error probability: 1 in 10^14 bits This isn't what WD's spec says. They say <1, not 1. The actual likelyhood of error is supposed to be lower. The issue is, how much lower? It depends on how conservative WD was and on whether they're trying to sell more expensive drives as more reliab...

Re: Bay-trail motherboards

The one you linked to isn't fanless. There's a fanless version which has a -EU suffix.

These TDP figures are useless. The CPU is sure to burn less than 17W. But yeah, it should be slightly less efficient than a Bay Trail for what that's worth.

Re: Real-World file server CPU requirements

If you wanted the full picture (in this case, I'd be content with a read test), you could write exactly what was on the drive in the first place. The risk isn't zero. Doing anything is risky. But that risk ought to be very small if you're careful. crappy RAID cards have bitten many people in the ass...

Re: Real-World file server CPU requirements

Sure, if I'm not mistaken there's one NIC we haven't heard about (who knows how bad it is?) and I guess I'm a bit of a switch snob because I don't associate D-Link with quality. I'm sure some of their switches are fast but it's certainly worth testing.

I assume the OP is talking about SMB performance which has issues you won't spot by benchmarking raw network throughput. Do bechmark it just in case but you can get slow SMB on a fast network.

I don't know what CPU you have, what other software you might run and so forth... but it looks like the minimum freq is set at 3Ghz so you might have to set it lower before you do anything else.

Yes, the price is basically the same as the 847 Celeron boards, which are dated and slow. Most faster Celeron solutions are significantly more expensive unless of course you avert your eyes from the cheaper case/PSU combos, insist on using expensive drives and so forth. And of course they use a fan!...

Re: Bay-trail motherboards

Going by johnnyguru's review, the efficiency ought to be a bit higher. Even if it burned 5W, what business does this board have to consume 10.5-11W DC anyway?
There are efficient (and quiet/silent!) PSUs in regular retail channels by the way.

You don't need a fast SSD or 8G of RAM for it.

There are cheaper case/PSU combos but I wouldn't skimp on this. Get a good one like the one Ab...
