Nexenta Object Storage for OpenStack- Nexenta

Nexenta Object Storage for OpenStack (NOST) product will add Object Storage services to NexentaStor 4th gen (4.x) servers. NOST is built upon Nexenta's Cloud Copy-on-Write (CCOW) technology that relies on ZFS data integrity while bringing ZFS design philosophy to object storage.

Unlimited scalability is easily, and frequently, claimed but rarely substantiated. This presentation will explain how CCOW basics and architecture, including: manifest (metadata) and chunk (payload) tracking subsystems that enable scaling without limits by mostly ignoring each other; cryptographic hashing that enables global deduplication; unlimited versioning which works even when during the worst possible network partitions. This presentation will further say how CCOW both relies on ZFS and extends the "copy on write" design strategy to the Cloud.
