CEPH STORAGE
Ceph
• Distributed storage system
• Run‘s on commodity hardware
• Selfhealing
• OpenSource
• CloudStack integration (by Wido den Hollander)
• Lessons learned:
• previous storage system was too unflexible

change later

• installation takes time
• XML file based unattended automation replace wizard
• Adaption of XML with hostname, SID, …
