OpenStack Storage Overview
3
SwiftHighly available, distributed, eventually consistent object storage. Uses commodity servers.
CinderBlock storage interface layer for cloud compute. Standardizes the use of traditional block storage.

OpenStack Swift – Cloud Storage
• Object storage– http REST APIs
• Distributed– Across geographies– Scalable– Masterless
• Commodity servers• Durable
– Multiple copies– Self healing
• Simple to manage• Multi-tenant

New Interface & Behavior with Swift… but don’t be Alarmed
5
• Swift is a new type of storage– Eventually consistent behavior– http APIs – put, get, post, delete– Requires application change
• …but don’t be alarmed– Cloud gateways to convert file or
block protocol to REST– Allow existing applications to use
the cloud– Additional features e.g. caching,
WAN op, encryption, dedupe etc.– TwinStrata, Panzura, Maginatics,
Riverbed, Nasuni, Maldivica etc.

OpenStack Cinder – Storage for Cloud
• Block storage interface– Integrate traditional block storage
with OpenStack compute “Nova”
• Integrated with Nova and dashboard– Supports Linux storage, Ceph,
NetApp, Nexenta, SolidFire, Zadara, gluster, IBM
• Performance optimized• Advanced capabilities
– Snapshot capability– Highly available, – Fault-tolerant, recoverable

Private Cloud Use-Case
• Large organizations– Scale-out more complex than scale-up– Needs skilled IT staff– Needs scale
• Swift/ Cinder mutually exclusive– Swift is good for private cloud storage– Cinder goes along with Nova, cloud
compute
• Companies providing private OpenStack Swift clouds– Rackspace, IBM, CloudScaling, Nebula,
Piston, SwiftStack, Mirantis etc.

Public Cloud Use-Case
• Any size organization– Eliminates capital expenditures– Eliminates capacity planning– Eliminates technology migration– Eliminates management of
equipment– Can complement a private cloud
• Companies providing public OpenStack Swift clouds– EVault, RackSpace, IBM, HP,
Internap etc.
