In Pure Storage, what is a 'pod' in the context of ActiveCluster replication?

Answer: A container object that holds volumes and snapshots that replicate synchronously between arrays

A pod is a logical container for volumes and snapshots that is stretched across two arrays in ActiveCluster, ensuring all contents replicate synchronously.

What Pure Storage feature sends FlashArray snapshots to public cloud storage (AWS, Azure, GCP) for long-term retention?

Answer: CloudSnap

CloudSnap replicates FlashArray snapshots to object storage in AWS, Azure, or GCP, enabling offsite, cloud-based data retention.

What is the maximum synchronous replication distance typically supported by Pure Storage ActiveCluster?

Answer: Limited by round-trip latency (generally ≤5 ms RTT)

ActiveCluster's synchronous replication is constrained by the round-trip latency requirement (typically ≤5 ms), which translates to roughly 50–100 km depending on fiber path.

Which CLI command is used to promote a replicated pod to read/write state during a Pure Storage ActiveDR failover?

Answer: purepod promote

The 'purepod promote' command promotes a demoted or DR pod on the target array to an active, read/write state during failover.

What happens to an ActiveCluster pod automatically when the primary site loses connectivity and the Mediator grants quorum to the secondary site?

Answer: The pod is promoted at the secondary site and becomes read/write without manual intervention

When ActiveCluster detects a site failure and the Mediator grants quorum, the surviving site automatically promotes the pod, allowing hosts to continue I/O with no manual steps.

What is the typical minimum RPO achievable with Pure Storage ActiveDR asynchronous replication?

Answer: Seconds (as low as ~30 seconds)

ActiveDR can be configured with replication intervals as low as approximately 30 seconds, providing near-continuous data protection for asynchronous DR.
