Pure Storage FlashArray – Product Analysis

Last updated February 19th, 2019 with added support for NVMeoF-RoCE. 12-page deep dive into the architecture and capabilities of Pure Storage FlashArray.

Pure Storage is a relatively new company that developed the FlashArray 400 series using standard servers and device enclosures and followed it with the second generation FlashArray//m with custom packaging for a purpose built system and a custom designed NVRAM module. The FlashArray is an modern design purposed built for solid state technology and is comprised of entry-level, mid-range and larger capacity arrays, ranging from to 400 TB in effective capacity. Pure Storage FlashArrays are all solid-state systems, and offer both FC and iSCSI block storage access. The company’s proprietary software system – the Purity Operating Environment (OE), is its 4th generation – offers five forms of data reduction, ensuring data is both deduplicated and compressed prior to being written. There is also additional post deduplicated processing for additional capacity optimization. Pure Storage claims there is no performance penalty for deduplicating data inline.

Pure Storage FlashArray systems compete against HP 3PAR 7450 and 7200 All-Flash Storage, EMC VNX F7000 and XtremIO, NetApp EF560, IBM FlashSystem, Violin Memory systems, Hitachi VSP G800 (populated with all SSDs), and other leading all solid state systems.

Pure Storage FlashArray//m Series arrays are general-purpose block storage systems designed for use in environments with high performance requirements, or multiple workloads running on the same storage system. Dual controllers provides HA along with incremental performance due to round-robin volume access to host volumes over multiple paths. Capacity may be scaled by adding additional storage enclosures.

Pure Storage system are designed as a general purpose, high performance storage system competing with Tier 1 storage systems. Target applications are those requiring high performance without a large capacity requirement.
