Pure Storage initially developed the FlashArray 400 series using standard servers and device enclosures
and followed it with the second generation hardware FlashArray//m and updated //X with custom packaging for a purpose built system and a custom designed NVRAM module. Later, the FlashArray//C was added to introduce a capacity-oriented system. The FlashArray is a modern design which was purpose built for solid state technology, and is comprised of entry-level, mid-range, and larger capacity arrays, ranging from 73 TB to 3.3 PB in effective capacity for the //X systems up to 5.5 for //XL models and up to 7.3 PB for their //C systems. Pure Storage FlashArrays are all solid-state systems, and offer both FC and iSCSI block storage access as well as NVMe-oF via RoCE. The company’s proprietary software system – the Purity Operating Environment (OE), offers 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. Active-active stretched clusters, portable snapshots including snapshots to clouds, and the ability to run VMs or containers on the storage system were added with Purity 5.
Pure Storage FlashArray systems compete against HPE Alletra, Dell EMC PowerStore, NetApp All Flash
FAS, IBM FlashSystem, Hitachi VSP E-Series, and other leading all solid state systems.
