Pure Storage has made available its second generation all-Flash enterprise storage arrays along with the 2.0 release of its Purity platform, adding high availability features, full data encryption and integration with VMware's vStorage APIs.
The FlashArray 300 Series is effectively the first publicly available product from Pure Storage, which has been working with customers under an Early Access Programme to bring its enterprise-class solid-state storage platform to market.
This is intended to compete with existing storage vendors on price, by using low-cost commodity multi-level cell (MLC) Flash components rather than more costly single-level cell (SLC) or enterprise-grade MLC, combined with software to provide de-duplication and boost reliability.
"Storage accounts for far too much latency, power, floor space and capital expenditure in the datacentre. We set out to push mechanical disk out of the performance path, and to do so by making all-Flash storage less expensive than arrays of 15,000rpm drives that do the performance heavy lifting today," said Pure Storage chief executive Scott Dietzen.
The FlashArray 300 Series is available in dual controller or single controller versions with up to 12 host I/O ports, with either 8Gbit/s Fibre Channel or 10Gbit/s Ethernet supported. The arrays offer a raw data capacity of 5.5TB up to 22TB.
One of the features of the Purity Operating Environment is always-on de-duplication, which enables the firm to claim an effective capacity of up to 100TB as well as delivering a high performance of up to 200,000 input/output operations per second (IOPS).
The major new feature in Purity version 2.0 is support for active/active high availability for mission-critical applications, while in the hardware all I/O operations are committed to mirrored non-volatile memory (NV-RAM), boosting performance by allowing all operations to be asynchronous to the host initiator.
Purity also includes a feature called FlashCare Technology to increase Flash memory cell longevity and reliability through techniques such as wear levelling and writes aligned to the block size of the Flash devices.
This enables the FlashArray to sustain years of high-throughput workloads while maintaining consistently low latency, without compromising the health of the Flash media and any data stored on it, the firm claimed.
Each FlashArray also implements its own Data Integrity Fabric to provide an extra layer of protection against bit errors via block-level and page-level checksums.
Meanwhile, Pure Storage has added support for VMware's vStorage API for Array Integration (VAAI), which allows for thin provisioning and offloading of other operations from the host to the array in virtualised environments based on vSphere 5.0.
Pricing for an entry-level high-availablity configuration of a FlashArray 300 Series with 50TB of usable data capacity is $150,000 (£94,821), which equates to a cost of $5 to $10 (£3 to £6) per gigabyte, according to Pure Storage.
