In this video from the LAD’15 Conference, Daniel Kobras from science+computing presents: Operational Characteristics of a ZFS-backed Lustre Filesystem.
“Historically, Lustre has only supported ext4/ldiskfs servers and while those servers have performed well they do suffer from a number of well known limitations. Extending Lustre to use a next generation filesystem like ZFS allows it to achieve greater levels of scalability and introduces new functionality.”
