Merkle Trees FTW, but it sounds like you've basically reimplemented ZFS. Have you tried using ZFS on one of these?

Earlier we were totally interested in ZFS, as it would replace RAID & LVM as well (and ZFS gets great reviews). But (to my understanding) native ZFS is not available on Linux and we're not really looking to switch to OpenSolaris. ANOTHER option down this line of thinking is switching to btrfs, but we haven't played with it yet. By the way, at Backblaze I've felt like we have had to implement several things that I wou…

Solaris isn't your only option. Various BSDs support ZFS quite well.

Curious, according to Intel, it the i3 doesn't do ECC: http://www.intel.com/support/processors/corei3/sb/CS-031175.... But the Supermicro board says it can: http://www.supermicro.com/xeon_3400/Motherboard/X8SIL.cfm The board also supports Xeon processors, so it might be that it only supports ECC with Xeon. However, I didn't see anything in the docs to support this, instead it says "Dual Core processors of Ci3 and Pen…

IIRC, some vendors wanted to offer super-low-end dual-core servers but rather than create a dual-core Xeon SKU Intel decided to just not disable ECC on some of the Pentiums and i3s. (As if their branding wasn't f'd enough.) So yeah, i3s support ECC when used in a server board.

We didn't think we even had a choice! From: http://www.supermicro.com/manuals/motherboard/3420/MNL-1130....

"The X8SIL/X8SIL-F/X8SIL-V supports up to 16GB of DDR3 ECC UDIMM or up to 32GB of ECC DDR3 RDIMM (1333/1066/800 MHz in 4 DIMM slots.)"

Below are what we assume are ECC errors from an i3 based Backblaze pod, when this happens it is usually bad RAM (bad enough to crash the pods, replace with fresh RAM repairs it):

We're using FreeBSD's ZFS support and haven't had any hiccups to complain about.

ZFS on FreeBSD works a charm - I was happy to switch to FreeBSD after having done OpenSolaris & Nexenta specifically for ZFS.

I actually use ZFS on Mac OS, as well, and have been happy with it there (thanks Dustin Sallings!).

FYI: Protocase ( http://www.protocase.com/ ), the company that will build you the Backblaze case, sent me an email yesterday announcing that they are now selling completed Backblase storage pods without the hard drives for $5395.00. I'm not sure if this is the new design or not but I've set up 3 of these and finding some of the parts (SATA back planes) took weeks of searching and shady dealings.

This is awesome and I hope to get our company to buy into this concept!

Feels similar to what the internet archive does.
