libgfapi and the Linux target driver (iSCSI)
Gluster blog stories provide high-level spotlights on our users all over the world This post describes modifications to the Linux Target driver to work with Gluster’s “gfapi” . It is a follow up to an earlier post on Gluster’s block IO performance over iSCSI. Those tests used FUSE, which incurred data copies and context switches.

GlusterFS replication do's and don'ts
GlusterFS spreads load using a distribute hash translation (DHT) of filenames to it’s subvolumes. Those subvolumes are usually replicated to provide fault tolerance as well as some load handling.
