Pure Storage announces all-flash array, cloud-based management and storage procurement

Pure Storage on Monday announced FlashArray//M, an all-Flash array, the Pure1 cloud-based storage management and Evergreen Storage, a new storage procurement and upgrade model.

Evergreen Storage replaces the 3-5 year rip-and-replace with a combination of FlashArray’s modular, software defined storage architecture and its maintenance program Forever Flash to ongoing upgrades and fair and pricing.

The company is also announcing Upgrade Flex Bundles, which allow enable customers who are expanding capacity to upgrade their FlashArray controller hardware.

The FlashArray//m features a 50% increase in performance, 2.6 improvement in density over previous FlashArrays. It features two Intel Haswell controllers, new NV-RAM cache modules and dual-drive flash modules in a 3U rack-mount chassis. Three choices of controllers are available: //m20, m50 and //m70. The //m20 has 120TB useable, storage; the //m50 has 250TB of usable storage and the //m70 has 400TB of usable storage. They perform at 150,000 32K IOPS to 300,000 32K IOPS.

Riding the Commodity Wave (CPU and NAND)

As with previous generations of FlashArray, Pure Storage set out to make All-Flash economically viable for Enterprises by designing Data Reduction into the core solution and riding the commodity hardware wave by standardising on x86 processor technologies leveraging Moore’s law.

With the FlashArray//m we’re building on this approach to leverage the economic benefits of Flash NAND density increases and have introduced new technologies like 12 Gb/s SAS, PCIe and NVMe enabling us to support more performant Flash technologies as they are released to market.

Modular Approach

FlashArray//m is a 3RU storage array which takes a ‘Modular’ approach to all components in the solution, we’ve moved to an all-in-one chassis ‘appliance’ design bringing together simplicity and expandability.

Introducing new NV-RAM Modules, Flash Modules and Controller Modules means you can increase storage density and storage performance independently, while retaining an ‘appliance’ like simplicity of management.

Upgrade Capacity and Performance

A single 3RU Chassis you can go from 5TB to 40TB raw (not including Data Reduction), thanks to 20 Flash Module slots which can accommodate different capacities, these are separated into 2 groups of 10 with the following configurations available with this initial release:

 

dditional external shelves can also be connected to increase storage capacity beyond these amounts.

The FlashArray//m comes with 2 NV-RAM modules as standard and can be expanded to 4 to increase performance.

This design approach enables an easy transition from previous FlashArray controller models, along with the ability to add larger capacity Flash Modules as denser NAND technologies become generally available.

This can include taking advantage of Forever Flash and upgrading your Controllers free of charge (you heard that right) without any downtime or performance impact.

Availability

As you’d come to expect with any Storage Platform there’s plenty of availability and redundancy built into the FlashArray//m with dual power supplies shared across the chassis and dual Controller modules which provide High Availability utilising a non-transparent PCIe bridge.

All Modular components are hot swappable in keeping with our ‘storage without compromise’ approach to maintaining availability without compromising performance.

Each Controller has the following interfaces: –

  • Dual Management 1GbE ethernet ports
  • 4 x 12Gb/s Mini-SAS HD ports
  • Up to 3 x PCIe Host IO Cards (2-port 8/16Gb Fibre Channel or 2-port 10GbE iSCSI)
  • Dual 10GbE Replication Ports.
