zfsIn this video from LUG 2015 in Denver, Gabriele Paciucci from Intel presents: ZFS as Backend File System for Lustre: the Current Status, How to Optimize, Where to Improve.

Lustre has supported ZFS as a backend filesystem since version 2.4. Lawrence Livermore National Lab has used ZFS in production for years and many sites are following their lead. At the same time, system integrators are actively evaluating inexpensive Lustre storage solution using ZFS and JBODs.

Intel supports users, system integrators, and OEMs using ZFS with Intel Lustre. In this presentation, we summarize the results of proof-of-concept (PoC) on a variety of the ZFS configurations. We cover sequential and metadata performance, data Integrity, manageability, availability and reliability. The work identifies the areas where development should be focused in order to fill gap in performance or functionality and encourage system administrator to integrate this technology with the existing high availability framework like Pacemaker/Corosync. We also cover the most important tunables for ZFS in combination with Lustre and the most notable metrics for Lustre and ZFS.”
