Detailed Specifications
HPE Q0U55A StoreFabric SN6600B 32 Gb Fibre Channel Switch
Overview
The HPE Q0U55A is a 1-rack-unit Fibre Channel switch, designed for data-centre SAN environments and storage architects needing high-density 32 Gb FC connectivity with scalability and enterprise features. It supports up to 48 device ports (24 active ports with licensing expansion) of 32 Gb Fibre Channel SFP+ and includes 4 QSFP+ ports for breakout or high-speed ISL trunking, delivering up to 2 Tb full-duplex aggregate bandwidth. With port-to-port latency around 700 ns, this switch is suited for virtualised storage fabrics, flash-based storage systems and SAN extension scenarios. Installation fits standard 19-inch racks and the unit provides hot-swappable dual power supplies and integrated fabric-monitoring tools via the HPE Fabric OS and SANnav ecosystem. It integrates into enterprise and hyperscale fabrics, offering advanced zoning, traffic management and diagnostics, and positions itself in core SAN racks, consolidation zones and high-availability storage infrastructure.
