Coho Data has a Cinder driver for its DataStream product.
The Coho Cinder driver is part of OpenStack Mitaka, released earlier this month. Coho says that, with its DataStream Cinder API, organisations can build OpenStack block storage infrastructure that dynamically scales both performance and capacity as application needs change. It claims Coho DataStream meets OpenStack’s primary design requirements by offering horizontal scalability, shared-nothing architecture and the ability to distribute everything. ®
