Coho Data, a start-up based in Sunnyvale, California with R&D in Vancouver (Canada) and Cambridge (UK), announced $25 million Series B funding to support its new storage architecture that combines flash arrays for performance, COTS server hardware for scale-out sizing, and SDN intelligence.

The funding round was led by new investor, Ignition Partners, and included existing investor, Andreessen Horowitz. The company plans to use the money to accelerate its go-to-market efforts as the it prepares for general availability of Coho DataStream later this year.
Coho Data, which was founded by key contributors to the Xen ecosystem, is taking a software-defined approach that combines commodity hardware with software that’s tuned for the latest PCIe flash technologies. The company said its team leveraged the experience of building the virtualization layer that powers Amazon’s EC2. The goal is an on-premise storage solution for data centers that delivers twice the price/performance of all-flash arrays. OpenFlow is used to embed storage intelligence in the network. A 2U Coho DataStream appliance provides Up to 180K IOPS and can be scaled linearly.
The Coho DataStream product line is currently installed in large enterprise private cloud environments and will be general available later this year.
