Detailed Specifications
HPE Q0U55B StoreFabric SN6600B 32 Gb Fibre Channel Switch
Overview
The HPE Q0U55B is a 1 RU enterprise class Fibre Channel switch optimized for storage area networks and engineered for high-density flash and virtualised storage environments. This model supports 32 Gbps port speeds and comes as a "48/24" configuration, meaning 24 ports enabled initially with expansion capability up to 48 active ports via licence. The "Power Pack+" edition includes advanced software features such as ISL trunking, Extended Fabric and Fabric Vision for monitoring and diagnostics. With an aggregate bandwidth of up to 2 Tbps and port-to-port latency around 700 ns, the switch supports low-latency, high-throughput block-storage traffic. Its 1 RU rack-mount form factor with redundant hot-swappable power supplies is suitable for data-centre core environments, SAN fabrics, and high-availability storage clusters. It integrates with the broader HPE StoreFabric ecosystem, allowing unified management of FC fabrics, diagnostics and zoning workflows.
