Explanation

Dell Unity XT and DR Design: For disaster recovery (DR) within a metro distance and zero Recovery Point Objective (RPO), synchronous replication is the preferred method. Synchronous replication ensures that data is written to both the source and target volumes simultaneously, which requires high performance to minimize latency. Best Practices for Minimizing Impact on Performance: Multiple Ports per Controller: While this can improve throughput, it does not directly minimize the latency impact of synchronous replication. Flash Tier in Hybrid Pool: Including a flash tier in a hybrid pool enhances performance significantly because flash drives offer lower latency and higher IOPS compared to traditional spinning disks. This is critical for synchronous replication scenarios where performance impact needs to be minimized. Thick Volumes: Using thick volumes can provide consistent performance, but they do not inherently minimize the impact of synchronous replication. Synchronous Replication Session: Creating the replication session before filling the source storage object with data is a procedural step and does not address performance during active
