Which is really the bane of all cluster file systems, isn't it? Meta
data accesses kill performance.
Ceph is a new distributed file system with an interesting way of handling
metadata.
"Ceph maximizes the separation between data and metadata management by
replacing allocation tables with a pseudo-random data distribution
function (CRUSH) designed for heterogeneous and dynamic clusters of
unreliable object storage devices (OSDs)."
They've got a prototype and quite a few research papers on their site.
