[Diego Parrilla Santamaría <diego.parrilla.santamaria@xxxxxxxxx>]

We have used Gluster for small deployments, but lately we have changed our
mind.  Basically we have bet on Gluster for 2013 because of:

- 10GbE everywhere, and Gluster MUST run in 10GbE (or Infiniband)
- 3.3 release fixes some issues when locking big files: Granular locking
- libgfapi reborn, no more FUSE overhead
- QEMU 1.3 comes with GlusterFS block driver
http://raobharata.wordpress.com/2012/10/29/qemu-glusterfs-native-integration/
- Success cases everywhere

Regarding our tests, NetApp and Nexenta outperforms Gluster, but let's say
we now can live with this performance penalty because cost per bit and
horizontal scalability are really good.

Cheers
Diego
