The HP A3724-90006 is a 10-port Fibre Channel Arbitrated Loop (FC-AL) hub designed for connecting storage systems and servers in legacy SAN environments. This hub supports short-wave fiber optic connections at standard FC speeds, providing loop-based fabric topology for modest-scale storage deployments. Compatible with HP SureStore E-series storage systems and other FC-AL capable devices, the unit offers straightforward daisy-chain configuration typical of loop topologies. Typical applications include departmental backup, archival storage, and smaller SAN clusters where loop-based rather than switched fabric architecture is preferred or required for legacy equipment compatibility. The refurbished unit has been tested and guaranteed to meet original specifications; available via quote from G5 Network Group.
