Pure Storage FlashBlade Architect Professional FAAA_004 Question # 8 Topic 1 Discussion

The customer has the following requirements:

Business-critical workload that requires sub-millisecond response times

Synchronous replication configured to their secondary site

Offload snapshots to a third location where they do not have a FlashArray

The best solution to meet these needs isFlashArray//Xs with ActiveCluster and CloudSnap.

Why This Matters:

FlashArray//Xs:

FlashArray//X is optimized forhigh-performance workloads, delivering sub-millisecond response times required for business-critical applications.

ActiveCluster:

ActiveCluster providessynchronous replicationbetween two sites within a stretched cluster, ensuring zero RPO and near-zero RTO for high availability.

CloudSnap:

CloudSnap offloads snapshots to cloud storage (e.g., AWS S3 or Azure Blob), enabling disaster recovery or archival at a third location without requiring an additional FlashArray.

Why Not the Other Options?

B. FlashArray//Cs with ActiveDR and Snapshot Replication:

FlashArray//C is designed for capacity-optimized workloads and does not provide the sub-millisecond response times required for business-critical applications.

ActiveDR provides asynchronous replication, which does not meet the requirement for synchronous replication.

C. FlashArray//Cs with ActiveCluster and Snapshot Replication:

Again, FlashArray//C is not suitable for sub-millisecond response times. Additionally, snapshot replication to a third location is less efficient than CloudSnap for offloading data to the cloud.

Key Points:

FlashArray//Xs:Delivers the high performance required for business-critical workloads.

ActiveCluster:Ensures synchronous replication for high availability across two sites.

CloudSnap:Provides cost-effective offsite protection by offloading snapshots to the cloud.
