About This Architecture

Dell SAN high availability architecture uses dual Brocade FC switches and redundant 16Gb Fibre Channel paths to eliminate single points of failure in the storage fabric. Dell PowerEdge servers connect to both Fabric A and Fabric B switches, which converge at a Dell PowerStore 1000T array via redundant storage FC paths and an ISL inter-switch link. This dual-fabric design ensures continuous I/O availability even during switch or path failures, meeting enterprise uptime requirements. Fork this diagram on Diagrams.so to customize fabric topologies, add additional servers, or adapt for your specific SAN capacity planning. The architecture demonstrates best practices for mission-critical storage infrastructure requiring zero-downtime failover.

People also ask

How do you design a high-availability SAN architecture with Dell storage and Brocade switches?

This diagram shows a dual-fabric SAN design where Dell PowerEdge servers connect to both Brocade FC Switch A and B, each with 16Gb paths to a Dell PowerStore 1000T array. The switches are linked via ISL, enabling automatic failover if either fabric fails, ensuring zero-downtime storage access for mission-critical workloads.
