The feature that allows forarray upgrades without any degradation in performanceisnon-disruptive upgrades.
Why This Matters:
Non-Disruptive Upgrades:
Pure Storage FlashArray supports rolling upgrades, enabling software updates (e.g., Purity//FA) and hardware upgrades (e.g., controllers) without interrupting operations.
During a controller upgrade, the active/active architecture ensures that one controller continues handling I/O operations while the other is upgraded, maintaining consistent performance.
Why Not the Other Options?
A. ActiveCluster:
ActiveCluster provides synchronous replication for high availability but does not directly relate to non-disruptive upgrades.
C. Right-Size Guarantee:
The Right-Size Guarantee ensures customers receive the expected effective capacity based on their workload's data reduction profile. It is unrelated to upgrades or performance.
D. Protection groups:
Protection groups are used for replication and snapshot management but do not impact the ability to perform non-disruptive upgrades.
Key Points:
Non-Disruptive Upgrades:Ensure seamless updates without impacting performance or availability.
Active/Active Architecture:Enables continuous I/O processing during upgrades.
Customer Experience:Minimizes downtime and disruption during maintenance or upgrades.
