What is Pure Evergreen?

Pure Evergreen is a storage modernisation model for Everpure / Pure Storage FlashArray and FlashBlade platforms running Purity OS. It enables organisations to keep enterprise storage infrastructure current over time through modular upgrades to hardware, software and storage media, rather than replacing the entire array during each refresh cycle.

How it works

Evergreen separates the storage platform into components that can be updated independently, so controllers, capacity and software can be modernised within the existing system. Non-disruptive Purity OS updates and eligible controller upgrades are delivered while systems remain online, allowing performance, functionality and security to improve without data migration.

The challenge it addresses

Traditional storage refreshes often force organisations into disruptive replacement projects, capital outlay and operational risk every few years. Evergreen addresses the need to expand capacity, improve performance and adopt newer technology without downtime, forklift upgrades or shortening the useful life of existing storage investments.

FAQ

What is Pure Evergreen?

Pure Evergreen is Pure Storage’s approach to continuously modernising enterprise storage without relying on repeated disruptive hardware replacement and data migration cycles.

The Evergreen portfolio combines ongoing software innovation, eligible hardware upgrades, capacity expansion and flexible commercial models while organisations continue using their Pure Storage platform. This can extend infrastructure lifecycles, reduce migration complexity and protect long-term storage investment.

How is Pure Evergreen different from a traditional storage refresh?

Pure Evergreen modernises eligible storage components incrementally rather than replacing the complete storage platform through periodic hardware refresh and data migration projects.

Eligible controllers, software and capacity can be upgraded while the platform remains operational. This allows organisations to introduce newer technology without repeatedly purchasing replacement arrays, planning large migration projects or accepting the disruption commonly associated with conventional storage refresh cycles.

What is the difference between Evergreen//One, Evergreen//Forever and Evergreen//Flex?

Evergreen//One provides Storage as a Service, Evergreen//Forever supports continuous modernisation of purchased storage, and Evergreen//Flex provides a more flexible subscription-based consumption approach.

Evergreen//One uses a consumption-based STaaS model. Evergreen//Forever focuses on ongoing software innovation and eligible technology refreshes for traditionally purchased Pure Storage infrastructure, while Evergreen//Flex separates aspects of storage consumption from conventional fixed hardware ownership.

What are non-disruptive upgrades in Pure Evergreen?

Non-disruptive upgrades allow eligible Pure Storage hardware and software components to be modernised without taking the storage environment offline or performing a traditional data migration.

Software updates and eligible controller upgrades can take place while applications continue accessing their data. This can reduce planned downtime, migration risk and the operational complexity normally associated with replacing enterprise storage platforms.

Does Pure Evergreen mean we never need to replace our storage infrastructure?

No, Pure Evergreen reduces the need for complete platform replacements, but individual controllers, capacity components and other eligible technologies can still change over time.

The distinction is that infrastructure can be modernised incrementally while the wider storage platform and its data remain in place. This reduces reliance on repeated full-platform replacements and large migration projects rather than eliminating physical hardware changes entirely.

Can Pure Evergreen scale as our data requirements grow?

Yes, Pure Evergreen supports eligible capacity expansion and technology upgrades as application requirements and enterprise data volumes increase over time.

Organisations can expand capacity without replacing the complete storage platform, allowing infrastructure to evolve alongside analytics, AI, virtualisation and other data-intensive workloads. This approach can maintain availability while protecting previous investment in the Pure Storage environment.

How does Pure Evergreen reduce storage lifecycle costs?

Pure Evergreen can lower lifecycle costs by reducing repeated platform replacements, complex data migrations and planned disruption associated with conventional storage refresh projects.

Continuous software innovation, eligible technology upgrades and incremental capacity expansion allow organisations to gain more value from existing infrastructure over time. Available subscription approaches can also improve cost predictability and make longer-term storage planning more manageable.

What Pure Storage platforms can use Evergreen?

Pure Evergreen is associated with Pure Storage’s enterprise portfolio, including FlashArray™ and FlashBlade®, with specific services and entitlements varying by platform and subscription.

Upgrade rights, commercial options and available Evergreen services depend on the storage platform and programme selected. Organisations should therefore assess the relevant Evergreen offering alongside their existing Pure Storage estate, storage architecture and workload requirements.

Is Pure Evergreen suitable for business-critical and disaster recovery environments?

Yes, Pure Evergreen can support business-critical and disaster recovery environments where storage availability, continuity and reduced disruption during infrastructure modernisation are important.

Non-disruptive upgrades can reduce planned downtime while ongoing software and platform improvements help keep storage environments current. This is particularly valuable where lengthy migrations or disruptive refresh projects could introduce unacceptable operational risk to critical applications.

Who should consider Pure Evergreen?

Pure Evergreen is suited to organisations seeking continuous storage modernisation, reduced migration complexity and more predictable lifecycle management instead of periodic disruptive refresh projects.

It is particularly relevant for organisations experiencing rapid data growth, operating business-critical applications or planning long-term Pure Storage investment. Existing and prospective Pure Storage customers can use Evergreen to modernise infrastructure progressively while protecting previous platform investment.
