Storage:• Every file is a collection of blocks

• Content-based addressing for blocks

• Partial file transfers, deduplication, efficient syncing

• Independent of storage backend (NFS, RADOS, …)

• OpenStack Object Storage API plus extensions

• An integral part of Synnefo

• - Single store for Files, VM Images

• - Uses common backend with Archipelago
