Purity//Assure is resiliency that never quits. Proven 99.9999% availability means your data is always available, always performing, and always protected – with no performance loss.
Non-disruptive maintenance, expansion, and upgrading of everything – all without performance impact. Hello weekends.
Designed for 99.9999% availability, FlashArray has no single point of failure, and all components are hot-swappable.
Adaptive dual-parity RAID-3D, always-on encryption, and end-to-end data integrity fabric mean zero data loss, ever.
Clustered controller design allows for the complete failure of a controller or any controller component without impacting operations.
Write IOs are persisted to NV-RAM modules, ensuring in-flight writes are protected against power loss and device failure.
Flash Modules, NV-RAM Modules, and controllers are hot-swappable for continuous operation, even when recovering from a failure.
Simply unplug a failed controller, cable up a new one, and the FlashArray is back to full-availability, all without any performance loss.
Non-Disruptive Capacity Expansion – Flash capacity can be added online and becomes instantly available.
Non-Disruptive Controller Upgrades – Performance can be expanded, even across generations, with no downtime.
Non-Disruptive Hardware Replacement – Maintenance or replacement of any failed component is performed online.
Non-Disruptive Software Upgrades – New features and flash technology advancements are easily enabled with software upgrades that are not only non-disruptive to availability, but also to the performance of applications.
And Only We Do It With 100% Performance – Although the IO handling of the FlashArray is active/active from all ports on both controllers, we reserve the performance of one controller on the backend. This enables all maintenance operations to be performed with zero performance loss.
RAID-3D protects against concurrent dual-drive failure, and re-builds around failures automatically within minutes.
Flash is more vulnerable to bit errors than hard drives. RAID-3D uses independent checksums and dedicated parity to detect and heal around bit error issues.
RAID-3D treats performance variability just like a failure, and uses parity to work around potential bottlenecks to deliver consistent latency.
Data is always secure via encryption, with no key management or performance loss.
100% of the data at rest is encrypted, protecting against drive theft or loss in transit or maintenance.
Encryption is always-on, inline, and has no impact on performance.
Patent-pending internal key management provides security without user intervention.
Multiple account types, directory-based authentication, and secure management connectivity enable secure administration.
