Last updated September 27th, 2019 to reflect the acquisition of IntelliFlash by DDN from Western Digital. 10-page unbiased deep-dive into the product architecture and advanced features of Western Digital IntelliFlash. Part of new Evaluator Group research on solid state.

IntelliFlash is a storage product, formerly owned by Western Digital, that evolved from the Tegile systems. In september 2019, Western Digitial’s IntelliFlash business was purchased by DDN.

The system design leverages common hardware platforms with systems utilizing standard bridge-bay controllers and storage in a single 2U enclosure. Storage controller features are delivered through a combination of open source ZFS, combined with Western Digital developed features, CLI and GUI.

IntelliFlash systems are designed as general purpose, high performance storage systems competing with other midrange storage systems. The IntelliFlash systems compete against HP 3PAR 9450 and 8200 All-Flash Storage, EMC Unity, NetApp EF570, IBM FlashSystem, EMC XtremIO, Hitachi VSP F-Series and other leading all-flash and hybrid storage systems.

IntelliFlash storage systems provide multi-protocol storage with both spinning media and NAND flash solid state disks as cache in the hybrid models. In some configurations, an all-flash system is possible with all data residing on flash.

Target applications are those requiring high performance, particularly those with large capacity requirements. IntelliFlash systems are designed as general purpose, high performance storage systems competing with other midrange storage systems. Target applications are those requiring high performance, particularly those with large capacity requirement. Effective capacity with compression and deduplication is listed as 4X the raw capacity.
