Which Cisco solution provides SAN slow-drain analysis?

Cisco Nexus Dashboard hosts Nexus Dashboard Fabric Controller, which provides SAN Insights and congestion-analysis capabilities for Cisco MDS Fibre Channel fabrics. Its slow-drain analysis identifies devices that consume buffer-to-buffer credits slowly and cause congestion, latency, frame drops, or reduced performance elsewhere in the fabric. Administrators can examine slow- drain statistics at switch and port levels, review metrics such as TxWait and credit-loss recovery, and analyze the affected topology. Cisco UCS Director is an infrastructure orchestration product rather than a SAN telemetry platform. Cisco Intersight focuses primarily on infrastructure lifecycle management, operations, and observability. Cisco UCS Central provides centralized management for multiple UCS domains but does not supply the required MDS SAN slow-drain analytics. Therefore, Cisco Nexus Dashboard is the applicable solution.
