HPE StoreFabric SN6700B
The HPE StoreFabric SN6700B Fibre Channel Switch is an ultra-dense 1U Gen 7 SAN switch built on OEM Brocade G720 hardware running Fabric OS 9.x. Optimized for flash storage and NVMe over Fibre Channel fabrics, it delivers fifty-six 64 Gb/s line-rate ports with port-to-port switching latency under 460 nanoseconds. It features autonomous SAN traffic monitoring with automated congestion mitigation to prevent slow-drain conditions. Used hardware buyers must check active port licensing counts (base models provide 24 enabled ports) and verify serial management connectivity.
