2013 2013-09 2013-09-30 ZFS Solaris (operating system)

shared by Graham Perrin on 09 Oct 13 - No Cached
  • August 16, 2013
  • What's New in OpenZFS
  • new features in Open (Illumos) ZFS. Some of the performance improvements
  • ...13 more annotations...
  • equivalents in Solaris 11 for some time
  • arc doesn't always need to make a copy
  • SUNBT6913905 IMPLEMENT ATA TRIM, SCSI WRITE SAME / UNMAP , THIN RECLAMATION
  • ZFS I/O priority inversion
  • Dedup of null blocks could use special treatment
  • L2ARC in memory overhead should be reduced
  • ARC metadata limit can have serious adverse effect on dedup performance
  • arc_meta_limit modernization
  • encryption, up-to 1MB recordsize, RAID-Z/mirror hybrid allocator, it does support 4k sector
  • good to see though that both Illumos and Oracle are innovating
  • LZ4 support in Illumos which is not in Solaris 11
  • they do not actively share code
  • competition might be good

  • Welcome OpenZFS

  • ...27 more annotations...
  • Ten years ago this month, I started my professional career at Sun Microsystems
  • unique environment
  • I knew we were building something special
  • local filesystems were considered a solved problem
  • pursue that dream
  • discarding those that impeded innovation
  • it was clear that ZFS would drastically alter the filesystem landscape
  • open our eyes to the power of open source
  • “Tonic” was the code name for what would become OpenSolaris
  • led me to Delphix
  • sliced through the constraints
  • into our engineering culture
  • Every technology company today owes its existence in some part to open source
  • ZFS is decidedly not
  • crossed technical and business boundaries beyond what the original ZFS team ever dreamed of
  • capture that potential and build something we are all proud to be a part of
  • building something bigger and better than anything that could ever be built within the closed walls of Oracle
  • OpenZFS is
  • a name to what we have already been doing
  • magnitude of features and improvements that can be made within our loose knit community
  • accomplish so much more
  • opportunity to build the most innovative and successful filesystem in history
  • raise awareness of the quality, utility, and availability
  • open communication
  • consistent reliability, functionality, and performance of all distributions
  • illumos (and its predecessor OpenSolaris) are relatively niche
  • create, embrace, and evolve open source communities that build platforms for the greater benefit of the industry

  • 18. September 2013
  • OpenZFS startet
  • Die Lizenz ist zwar frei, was die direkte Verwendung von ZFS in FreeBSD, Illumos und Mac OS X ermöglicht
  • ...2 more annotations...
  • ZFS für Linux kann jedoch als Modul außerhalb des Kernels bereitgestellt werden, wofür bereits das Projekt ZFS on Linux sorgt.
  • Das Ziel von OpenZFS ist es, das seit über einem Jahrzehnt entwickelte ZFS in offener Weise weiterzuentwickeln
