Distributed Storage – CEPH
TT1235 - Petabyte scale out Rocks - Ceph as Replacement for Openstack's Swift and Co
8
CEPH – What?
• So-called parallel distributed cluster file system
• Started as part of PhD studies at UCSC
• Public announcement in 2006 at 7th OSDI
• File system shipped with Linux kernel since 2.6.34
• Name derived from pet octopus – cephalopods
9
Shared File Systems – Short Intro
• Multiple server access the same data
• Different approaches
‒ Network based, e.g. NFS, CIFS
‒ Clustered
‒ Shared disk, e.g. CXFS, CFS, GFS(2), OCFS2
‒ Distributed parallel, e.g. Lustre .. and CEPH
10
CEPH and Storage
• Distributed file system => distributed storage
• Does not use traditional disks or RAID arrays
• Does use so-called OSDs
‒ Object based Storage Devices
‒ Intelligent disks

CEPH Block Device
• Aka RADOS Block Device (RBD)
• Second part of the kernel code (since 2.6.37)
• RADOS storage exposed as block device (dev/rbd)
‒ qemu/KVM storage driver via librados/librdb
• Alternative to:
‒ Shared SAN/iSCSI for HA environments
‒ Storage HA solutions for qemu/KVM and Xen
• Shipped with SUSE® Cloud
