OpenSolaris ZFS vs. Linux ext3 RAID5
,----[ Quote ]
| Few overarching conclusions can be drawn from the limited results of this
| study. Certainly, there are situations in which the Solaris/RAID-Z1
| configuration appears to outperform the Ubuntu/RAID-5 configuration. Many
| questions remain regarding the large discrepancy in CPU usage for small-file
| operations. Likewise, the Ubuntu/RAID-5 configuration appears to perform
| slightly better in certain situations, though not overwhelmingly so. At best,
| under these default configurations, one can say that overall the Solaris
| configuration performs no worse, and indicates that it might perform better
| under live operating conditions. The latter, though, is largely speculation.

ZFS on Linux: It's alive
,----[ Quote ]
| The project is working, with several users running and even booting from a
| ZFS volume. Correia has not undertaken any performance tuning yet, and
| one sysadmin, Chris Samuel, has posted benchmarks that clock only about
| half the speed of another Linux filesystem, XFS.

ZFS Filesystem for FUSE/Linux
,----[ Quote ]
| ZFS is an advanced modern general-purpose filesystem from Sun
| Microsystems, originally designed for Solaris/OpenSolaris.
|
| This project is a port of ZFS to the FUSE framework for the
| Linux operating system.
|
| It was sponsored by Google, as part of the Google Summer of
| Code 2006 program.

Linux: Btrfs, File Data and Metadata Checksums
,----[ Quote ]
| Chris Mason announced an early alpha release of his new Btrfs
| filesystem, "after the last FS summit, I started working on a new
| filesystem that maintains checksums of all file data and metadata." He
| listed the following features as "mostly implemented": "extent based file
| storage (2^64 max file size), space efficient packing of small files,
| space efficient indexed directories, dynamic inode allocation, writable
| snapshots, subvolumes (separate internal filesystem roots), checksums on
| data and metadata (multiple algorithms available), very fast offline
| filesystem check".

Rampant layering syndrome
,----[ Quote ]
| It's another post from a ZFS developer's blog. This time, it's Jeff
| Bonwick responding to Andrew Morton's claim that ZFS is a "rampant
| layering violation" because it cuts across the traditionally
| separate worlds of the filesystem, volume manager, and RAID controller.
