Break the IT and resource-limiting cycle of traditional legacy storage offerings. Pure’s Evergreen architecture delivers IT agility and breaks the painful legacy storage process of buy, replace, repeat. Pure’s approach has been part of our DNA from the start and was designed to enable continuous upgrades of storage without disruption or performance impact.
Forklift Upgrades/Limitations of Legacy Storage
Forklift upgrades are complete overhauls of the IT infrastructure: Old and outdated storage systems are ripped out and replaced with newly purchased technology. The process is complex, wasteful, and time-consuming. Forklift upgrades are driven by architectural incompatibilities between storage generations or limitations in scale-out architectures that can’t add new nodes to existing arrays or clusters.
How does Pure’s Evergreen architecture provide non-disruptive upgrades?
Our core design philosophy delivers a modular, software-driven, stateless architecture that was built to be upgraded non-disruptively. Controllers and blades are upgradeable to deliver performance needed to meet modern workloads, with zero impact to operations. With cross-generational compatibility built in, different flash geometries can be mixed within an array, and newer controllers can work seamlessly with older flash modules. This technology is customer-proven across eight hardware generations, over 10 years, and with more than 10,000 controller upgrades.
How is Evergreen architecture different from other storage technologies?
Everything in our system was designed to be upgraded from the bottom up. All systems are tested for backwards compatibility and the ability to upgrade non-disruptively before release. For example, older SAS-based systems (serial attached SCSI) with legacy NVMe flash drives can be mixed with newer generation drives on the same array. Similarly newer controllers are tested to work with older flash drives. This means no “surprises” when it’s time to upgrade controllers, and only controllers need to be upgraded—nothing else needs to be replaced or repurchased.
What Evergreen Architecture Delivers to Customers
Something magical happens when you know you can upgrade your existing data storage infrastructure indefinitely, without downtime or disruption—in other words, with peace of mind.
