Enterprise Business Continuity for All

Data backup and disaster recovery are critically important – but with Purity ActiveCluster, we go much further. ActiveCluster is complete business continuity, built-in to every FlashArray.


Achieve new levels of availability with Purity ActiveCluster. Get worry-free business continuity – and zero RTO & RPO – across your data center, metro region, or globally, with async, across three data centers. You can set it up in minutes, and Pure1™ Cloud Mediator means you don’t need a third site. ActiveCluster is included with Purity//FA 5.

ActiveCluster – Ultra-simple and ultra-free

Business continuity that requires no third site, no extra hardware or licenses, and no more than a few minutes to set up? Check it out.

Designed to be Easy and Automatic

Managing an ActiveCluster stretch cluster is as simple as managing a single array: snapshot and clone operations can be performed from either array, and volumes and snapshots are synchronously maintained on both arrays. Failovers are transparent, and the arrays automatically resynchronize.

ActiveCluster Stretch Cluster for Business Continuity

Always-On Protection

Synchronous replication and transparent failover together deliver zero RPO and zero RTO. Get high availability across arrays, data centers, or a metro region. Or add asynchronous replication for a three data center recovery option.

Four Commands
to Deploy

Purity ActiveCluster is Active/Active, with a cloud mediator built-in to Pure1. Setup everything in minutes with just four simple steps – no outside professional services required. Then monitor your system via the Pure1 cloud.

It’s Yours at no Extra Charge

Business continuity is normally an expensive proposition. But Purity ActiveCluster is built-in, requires no additional license or fees, no external appliances, and no third backup site. It’s a simple Evergreen upgrade to Purity//FA 5.

Built with Purity Snapshots and Replication

Purity Operating Environment already offers space-efficient disaster recovery and protection: snapshots and replication are built-in, data reduction-aware, and simple to set up. ActiveCluster goes the next big step – synchronous replication and stretch-cluster enabling business continuity across metro regions for mainstream Tier 1 deployments. And still simple.

The Game Changers

What’s made us a 2017 IDC MarketScape leader?
A strategy for the future that includes being the only enterprise storage vendor today to offer stretch cluster at no additional charge. 

Lose the Cost and Complexity

To date, business continuity (and/or synchronous replication for zero RTO) has been available and affordable to only a select few organizations – and for only a few mission-critical applications – due to total costs of up to 100s of thousands of dollars, complex implementations, and the need for additional software licenses, a third site mediator, and external gateways. Not anymore – Purity ActiveCluster changes everything.

How Will You Use ActiveCluster?

Think always-on operations, zero RPO & RTO disaster recovery, data sharing (for dev/test, analytics, etc.), non-disruptive data migration, and business continuity across your data center, metro region, or globally (async 3rd site). Purity ActiveCluster is perfect for clustered apps (Oracle, SQL, etc.) and VMware VMSC.

Business Continuity for Clustered Apps

Live Migration

Move workloads at will as capacity growth and performance needs require.

DC Availability

Achieve an even higher level of availability within the data center.

Campus or Metro Availability

ActiveCluster maintains uptime even if one site should fail.

3DC Protection

Available global protection with 3 data center configuration (async 3rd site).


Multi-site, Active/Active design is fundamental to the effortless experience of Purity ActiveCluster. Unlike Active/Passive implementations, ActiveCluster serves I/O on a given volume from both sites simultaneously. You don’t have to worry about the complexity of managing VM or database instance affinity to a site, and application latency is optimized with reads served locally.

Your Applications Won’t Blink

Applications like SAP, Oracle, Microsoft SQL, VMware, or Hyper-V deployed on Purity ActiveCluster can continue running seamlessly, even if a disaster takes down an entire array, a whole data center, or an entire metro region.

Just Four Steps

Stretch cluster deployments have been intimidating from the customer’s point of view. Look at the length in pages of the manuals from some of our major competitiors: 769 pages; 1,360 pages. It doesn’t have to be that way. You can launch ActiveCluster in minutes – with just four steps.

About the time it takes to brew coffee

How easy and quick is it to set up business continuity via Purity ActiveCluster? Watch the entire process – in 7 minutes.

Pure1 Cloud Mediator Ensures Safe Failover

Purity ActiveCluster uses Pure1 Cloud Mediator, a SaaS-based quorum witness, which means there’s no need for you to have a third site. Failovers happen safely, automatically and transparently. If an array fails, the Cloud Mediator ensures your hosts simply access data on the other array.


With Purity ActiveCluster, the following types of failure are completely transparent to your applications:


Your application host can fail.


One of your arrays can go down.

Data Center

One of your data centers can go offline.


Your whole network could go down.
