Linux "There has been work by the Lawrence Livermore National Laboratories in porting ZFS to Linux as a native Linux kernel module. This LLNL ZFS work though is incomplete but still progressing due to a US Department of Energy contract. It is though via this work that developers in India at KQ Infotech have made working a Linux kernel module for ZFS. In this article are some new details on KQ Infotech's ZFS kernel module and our results from testing out the ZFS file-system on Linux."

ZFS "benchmarked" using a single drive?

From the Phoronix article:

A 60GB OCZ Vertex 2 SSD was used for benchmarking these different file-systems. We had also ran a similar subset of these tests on a standard 7200RPM Serial ATA 2.0 hard drive and proportionally these results didn't end up being different on an HDD over an SSD.


One of the main features of ZFS is storage pooling, and getting rid of all the hassles of managing multiple disks. Testing it on a single disk without testing it on multiple disks is pretty much pointless.

Sure, some people run it on their laptops with a single disk, to get access to all the snapshots and checksumming. But that's an edge use-case, not the primary one.

Sometimes, I think Phoronix just "benchmarks" random things, throws them up on the 'net, and waits to see what sticks. There's really no statistical methodology in place.

On the flip-side, the race is now on to see who gets ZFSv28 first: FreeBSD 9.0 or Ubuntu 10.04 LTS (and whatever other distros KQI supports)

There are ZFSv28 patches available for 9-CURRENT right now, but nothing committed to the source tree as yet. And the Linux kernel is in "limited beta". Both with a release date of "early 2011".
