Ex-stealthy startup Coho Data, developer of a “flash-tuned scale-out storage architecture designed for the private cloud that delivers unparalleled performance at public cloud capacity pricing,” has collared $25m in B-round funding.
The DataStream 1000 array is a 2U dual-controller, using OEM’d commodity-based server hardware, which can be added to, scale-out fashion, with its distributed system software. The idea is to deliver public cloud pay-as-you-grow economics in a private cloud built from an on-premise set of boxes.
An 11U Coho system consists of a switch plus five MicroArrays providing 190TB of capacity and 900,000 IOPS, with a list price of $530,000. It’s not cheap. Coho asserts that you’d need to spend $1.5m at list price to get a traditional 190TB, monolithic array. It would need 50U of rackspace and deliver only 250,000 IOPS.
