If you really want to keep the heat generation to a minimum, consider a PicoPSU: http://www.mini-box.com/s.nl/sc.8/category.13/.f This moves the voltage conversion electronics outside the case, and the PSU itself is tiny and very efficient. They make them up to 160 Watt. I bought an 80...

Not that monitoring HDD temps is not a good idea, but the Google HDD failure paper indicates that a drive's operating temperature has very little effect on its life.

Something else you may want to consider is if you want the system/boot drives to be in a RAID, I didn't use FreeNAS because it cannot have redundant ZFS system drives, whereas NexentaStor can, not sure about Eon.

This really does depend on what you are doing with it, I'm running a D525 Atom and I have never seen it over 25% running NexentaStor, might be more with FreeNAS, but if you just using it as a NAS then an Atom should be fine.

Last I checked, the boot drive for FreeNAS cannot be ZFS so you can't create a ZFS "syspool" mirror. This was the reason I didn't choose FreeNAS for mine. You probably don't need a lifetime warranty, it will either fail or you will voluntarily replace it before 5 years, but I have found that...

I run Nexenta from a USB flash drive, three actually, I have a 3x mirror. I have been running it for about 14 months now, one drive has run perfectly fine the whole time, two failed after 1 month, three more failed after about 2-3 months, and one other has been running fine for about 8 months...

There's EON too: http://eonstorage.blogspot.com/ And Windows I guess... if you're into that sort of thing. :)

It was generally good for the price at the time, but the firmware had a few problems and it only ran BusyBox so even though you could get shell access there was only so much it could do, other than serving files. The biggest problem a lot of users had was its annoying tendency to wipe the...

IMO the main reason you DIY is for flexibility and performance. Most consumer-level NASs are very limited in their scope, they have a web front-end that protects the user from the complicated stuff, but that also means that they are very specific in what they can do. I used to have a DLink...

Yes, as long as the new OS supports the same or higher ZFS version. It's actually very simple, you just tell the OS you want to export a file system, and it will make sure everything is written to disk then remove all references of it from the current OS. Then you pull the disks and put them...

I subcontract for a government department with about 23 servers around the state, I have been here for 5 years and we've only had a single instance of a server reporting a single bit error in memory. I was never clear about whether modern, non-ECC memory can actually detect errors.

The only symptom of a bitflip will be either a file that doesn't work at all or does work, but isn't quite right, the system may also crash altogether. I just tried with a PNG image, flipping a bit about halfway through the file corrupts everything from that point onwards: the bottom half of the...

I presume you mean RAID-Z2 (equivalent to RAID6). Yes, 512e (512 byte emulation) as opposed to 4kn (4 kilobyte native) is the issue here. As GregN said though, these Hitachis are 512 byte native disks, so the only issue you will have is with addressing more than 2.19TB in the partition table...

Once you run ZFS inside a VM you will lose ALL its advantages and features, as the hypervisor controls the disks. You can ADD to a zpool containing a RAIDZ2 vdev, but you cannot EXPAND the vdev itself (this is actually the most requested feature for ZFS). If you initially create a zpool...

NexentaStor does not have a local GUI, it does use a user-friendly console system though, called Nexenta Management Console (NMC). Typing "help" will bring up the list of commands available. These commands can be used to show a cursor-navigable list of available options, you just navigate...
