Inside Lustre HSM


As Lustre has been transformed from a national lab supercomputer science project to an enterprise-quality file system, customer requirements have changed accordingly. One of the features about which the most questions have been asked is automated data movement within multi-tier storage systems. With Lustre 2.5 and the HSM functionality enabled, this goal has now been reached. Although this functionality is new to Lustre, it is important to remember that the French Atomic Energy Commission (CEA), which leads the development of HSM for Lustre, has been running HSM in production for several years within the Tera 1xx systems. Seagate plans to deliver a fully tested and supported version of Lustre 2.5.x with HSM-ready capability in our ClusterStorengineered solution for HPC and Big Data by early 2015. The exact specification cannot be described at this time, and possible back-end implementations (outside the obvious HPSS and POSIX CopyTools) will have to be defined at a later stage
