Integrating gluster fs,_qemu_and_ovirt-vijay_bellur-linuxcon_eu_2013

  1. 1. Integrating GlusterFS, qemu and oVirt Vijay Bellur Gluster Workshop – LinuxCon EU 2013
  2. 2. The Future of Storage is Open for Business 2 Agenda ➢Introduction ➢GlusterFS as VM Image Store ➢Integration with QEMU ➢Integration with oVirt ➢Q&A
  3. 3. The Future of Storage is Open for Business 3 GlusterFS Global namespace Scale-out clustered storage building blocks Support thousands of clients Access using GlusterFS and NFS protocols Linear performance scaling
  4. 4. The Future of Storage is Open for Business 4 KVM and Qemu KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions. Qemu is the driver for KVM virtualization
  5. 5. The Future of Storage is Open for Business 5 ➢ Large scale, centralized management for server and desktop virtualization ➢ Open source alternative to vCenter / vSphere ➢ Focus on KVM oVirt
  6. 6. The Future of Storage is Open for Business 6 GlusterFS 3.3 ➢ Granular data self heal ➢ Pro-active self healing ➢ Online data migration with remove-brick ➢ Support for O_DIRECT in FUSE
  7. 7. The Future of Storage is Open for Business 7 GlusterFS 3.4 ➢Improved write-behind behavior ➢libgfapi with support for DVM ➢Block Device Translator ➢Support for volume/cluster management from oVirt ➢FUSE ➢ Scatter – Gather patchset ➢ gid caching ➢ Configurable fuse queue length ➢ aio support in posix translator
  8. 8. The Future of Storage is Open for Business 8 GlusterFS 3.5 ➢ fallocate() support ➢ zerofill support in libgfapi ➢ Improved block device translator ➢ File snapshots
  9. 9. The Future of Storage is Open for Business 9 QEMU & GlusterFS Integration Integration possible through: ➢ GlusterFS native client - possible with qemu 1.2 and GlusterFS 3.3 ➢ GlusterFS NFS – possible with qemu 1.2 and GlusterFS 3.3 ➢ libgfapi – possible with qemu 1.3 and GlusterFS 3.4
