A SAN administrator is troubleshooting a synchronized data mirroring issue between the primary and DR datacenters. The datacenters use routed FCIP traffic over a WAN for the mirror traffic. The mirror

Using FC Ping measures latency, which is a diagnostic step, but does not directly resolve the underlying issue of insufficient WAN capacity or performance causing the breaks.

Synchronized data mirroring across a Wide Area Network (WAN) demands consistent low latency and sufficient bandwidth to ensure data integrity and prevent timeouts. When mirror relationships frequently break, it strongly suggests the WAN infrastructure, particularly its bandwidth, is unable to handle the continuous data stream required for synchronous replication, making increasing bandwidth a crucial first step to resolve performance bottlenecks.

Adding more FCIP routers primarily enhances redundancy or segment fabrics, but does not directly address a bandwidth or performance bottleneck that causes synchronous mirror relationships to break.

Stopping all mirror traffic prevents further breaks but does not resolve the root cause of the performance issue and effectively halts the critical replication process.
