OpenZFS Performance Optimization

Description

OpenZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the OpenZFS community. This repository contains the code for running OpenZFS on Linux and FreeBSD.

OpenZFS is an open-source storage platform. It includes the functionality of both traditional file systems and volume manager. It has many advanced features including:

  • Protection against data corruption. Integrity checking for both data and metadata.

  • Continuous integrity verification and automatic “self-healing” repair

    • Data redundancy with mirroring, RAID-Z1/2/3 [and DRAID]

  • Support for high storage capacities — up to 256 trillion yobibytes (2^128 bytes)

  • Space-saving with transparent compression using LZ4, GZIP or ZSTD

  • Hardware-accelerated native encryption

  • Efficient storage with snapshots and copy-on-write clones

  • Efficient local or remote replication — send only changed blocks with ZFS send and receive

 

OpenZFS is widely used in Lustre and HPC area. It’s better for us to do the optimization and performance benchmark for it.
