Purity Is Built for Cloud Era Flash

Purity Operating Environment is the software that powers every Pure all-flash array.

Software That’s Generations Ahead

Purity delivers comprehensive, Tier 1 data services to all workloads – even as it provides global flash management to your arrays. Moreover, Purity enables consistent low latency, data protection, and non-disruptive “everything” – and it’s resilience means full performance through array maintenance and failures. Need more proof of it’s power? Purity’s industry-leading data reduction is typically 2x better than the competition.


A next-generation AFA like FlashArray//X would not be possible without the breakthrough performance and resiliency of Purity for FlashArray. The microsecond latency, unprecedented density, and GBs of bandwidth //X offers are powered by Purity//FA 5.


Now every enterprise can achieve zero RPO and zero RTO across racks, data centers, or metro regions, effortlessly and affordably. Purity//FA 5 introduces multi-site stretch cluster with Purity ActiveCluster – always-on, Active/Active protection that’s built-in and a snap to setup. No additional cost, and no external controllers or third site required – Purity ActiveCluster is a simple Evergreen software upgrade.

Purity//FA 5 Unveils Purity//Run

Purity//FA 5 rounds out FlashArray with Purity//Run – an open platform for running applications on Purity that’s ideally suited to lightweight, data services-oriented processes requiring maximum high availability. Now you can run VMs and containers on FlashArray! Windows Storage Server is the first data service built on Purity//Run, adding NFS and SMB support to FlashArray. 

Purity Reduce:
Unbeatable Data Reduction

Purity delivers the industry’s most granular and comprehensive data reduction – typically 2x better than the competition. And unlike other vendors, it’s built-in, always on, and requires no tuning. You’ll buy less storage now, and less storage in the future!

: 1 AVERAGE TOTAL REDUCTION RATE (Deduplication, Compression and Thin Provisioning)

Purity Assure: Goodbye Downtime

With proven 99.9999% availability over two years, inclusive of generational upgrades, Purity keeps your data and applications safe, secure, and available at all times – without performance loss. In addition, Purity features QoS, giving you effortless control over your workloads. No more noisy neighbors, maintenance windows, and long weekends in the data center!


Data within FlashArray is continuously protected with FIPS 140-2 validated AES-256 data-at-rest encryption and is the only all all flash array to achieve NIAP / Common Criteria Certification. Additionally, Pure’s Rapid Data Lock, a smart card-based instant locking protects against emergency data center breaches.

Purity Protect: Never Be Without Your Data

Purity ActiveCluster is just one part of the data protection delivered by Purity. For added peace of mind, Purity offers space-efficient disaster recovery and protection – both locally and globally. Snapshots and replication are built-in, data reduction-aware, and a snap to set up. Get protected within minutes with complete policy-based automation.

We're Prepared for Anything

Recover instantly from anywhere. FlashRecover delivers built-in, space-efficient disaster recovery and protection – both locally and globally. Set up and get protected within minutes with complete policy-based automation.


We believe in open platforms. Purity’s available cloud connections, integrations, and REST APIs ensure that our cloud era flash will integrate with what matters in your data center. VMware vCenter, vRealize, OpenStack, and many more. Best of all, Purity’s simplicity means that FlashArray and FlashBlade™ are fully automatable.

The Power Behind FlashBlade Scale

FlashBlade is the industry’s first cloud-era flash purpose-built for modern analytics, delivering unprecedented performance for big data applications. Its massively distributed architecture enables consistent performance for all analytics applications using NFS, S3/Object, SMB, and HTTP protocols. FlashBlade is as simple as it is powerful, and all driven by Purity//FB2.

Purity Delivers Scale-Out Storage

FlashBlade is built on scale-out metadata architecture, capable of handling 10s of billions of files and objects while delivering maximum performance. Storage services at every layer are elastic, thanks to the distributed transaction database built into the core of Purity for FlashBlade. As with //X, Purity provides global flash management and effortless scale: simply adding additional blades grows system capacity and performance, instantly.

Object Store is now Fast Store

Archive. Cold Storage. Object systems today are built for cheap and deep storage. With the emergence of modern data analytics like Spark and deep learning, organisations can finally unlock the potential hidden in their data. Purity//FB 2 now supports S3 protocol, delivering ultra-fast performance for objects.

FlashBlade – Now with Snapshots

Delivering rapid innovation is part of who we are. Purity//FB 2 introduces a wave of new enterprise features, like snapshots, SMB, LDAP, network lock management (NLM), and IPv6, to extend FlashBlade into new use cases. In particular, snapshots bring ultra-fast performance for data protection and recovery, accelerating workflows in enterprise deployments like software development and databases.


What if storage software could talk directly to raw flash? With DirectFlash™, now Purity can. Purity interfaces directly with flash media via PCIe/NVMe, providing global flash management, I/O scheduling and optimisation, and end-to-end garbage collection. In effect, we’ve eliminated the performance challenges inherent in a “black box” SSD – by redefining the SSD. DirectFlash means faster, more efficient storage from the same raw flash!
