Ceph is a free-software storage platform, implements object storage on a single distributed computer cluster, and provides interfaces for object-, block- and file-level storage. Ceph aims primarily for completely distributed operation without a single point of failure, scalable to the exabyte level, and freely available.

NOTE: Ceph does not do backups. If you need backup, one alternative is mount the Ceph project as a network drive and use Crashplan to backup contents in your Ceph project. Users are responsible for their data. Ceph will not lose data due to mechanical failure, but we cannot protect against user error.

Groups that use Ceph as home directory have access to their projects when they login to Sol. All others can access their Ceph projects at /share/ceph/projectname
