Technical Overview of HPE’s Acquisition of Nimble Storage and Its All‑Flash Solutions

HPE’s recent acquisition of Nimble Storage is examined as a strategic move to strengthen its flash‑based storage offerings, complementing existing 3PAR solutions and addressing gaps in Original AFA products and SDS controller technologies.

Nimble’s CS product line—CS2000, CS400, and CS7000—targets hybrid storage scenarios such as Exchange, SQL, and virtual machines, employing RAID‑6 and Triple Parity for data protection and leveraging InfoSight for management; the CS7000 series also introduces an All‑Flash chassis with Scale‑Out support.

The storage architecture relies on the proprietary CASL (Cache‑Accelerated Sequential Layout) algorithm built on a multi‑core CPU foundation, a log‑structured file system, online data compression, sequential striping, and efficient garbage collection, converting random writes to sequential writes and performing LZ4 block compression.

Nimble’s All‑Flash AF series (AF1000, AF3000, AF5000, AF7000, AF9000) delivers high performance—up to 30 0000 IOPS per node and 1.2 M IOPS for a four‑node system—using Samsung 2.5‑inch 3D TLC V‑NAND SSDs ranging from 240 GB to 3.84 TB, with optional 10 GbE connectivity and scalable rack configurations.

The Multicloud Flash Fabric enables seamless data movement across private and public clouds, integrates with OpenStack services (Cinder, Swift, Glance), and utilizes Nimble Cloud Ready Flash arrays and InfoSight’s predictive analytics to simplify data‑center and cloud operations.

The piece also places Nimble within the competitive landscape, noting head‑to‑head positioning against EMC XtremIO, HDS, HPE StoreServ, IBM FlashSystems, NetApp AFF, SolidFire, Tegile, Tintri, and Violin Memory, while reflecting on the broader consolidation trends among flash‑focused startups.
