I'm looking at Gluster for 2 purposes:
1) To host our "database" volume. This volume has copies of several
protein and gene databases (PDB, UniProt, etc). The databases
generally consist of tens of thousands of small (a few hundred KB at
most) files. Users often start array jobs with hundreds or thousands
of tasks, each task of which accesses many of these files.
From our testing we found gluster with many small files to be rather
slow (GigE). Each open() will go over the network and will effectively
kill read performance (5-7 MB/sec). We tried to serve webapps with many
small files and startup time was not tolerable.
Of course, you need to test yourself ;)
