Exhibitcontrollers of a Pure Storage FlashArray, specifically labeled asCT1(top) andCT2(bottom). This labeling is consistent with Pure Storage's naming convention for its controllers.

Why This Matters:

Controller Identification:

Pure Storage FlashArray controllers are typically labeled asCT1andCT2to distinguish between the two controllers in an active/active architecture.

Both controllers work together to provide high availability and redundancy, ensuring seamless operation even if one controller is offline for maintenance or upgrades.

Active/Active Architecture:

In an active/active design, both controllers share the workload equally. If one controller is taken offline, the other seamlessly handles all I/O operations without impacting performance or availability.

Why Not the Other Options?

B. Top: Primary, Bottom: Secondary:

Pure Storage does not use "Primary" and "Secondary" labels for its controllers. Instead, it uses specific identifiers like CT1 and CT2 to refer to the controllers.

C. Top: CTO, Bottom: CT1:

The label "CTO" is not a valid designation for FlashArray controllers. Pure Storage consistently uses CT1 and CT2 to identify the controllers.

Key Points:

Controller Labels:Pure Storage FlashArray controllers are labeled as CT1 and CT2.

Active/Active Design:Both controllers operate simultaneously to ensure high availability and performance.

Redundancy:The dual-controller architecture provides fault tolerance and minimizes downtime during maintenance or failures.
