PM8379 Description
PM8379 CTS 20x4G Advance 20-Port 4.25 Gbit/s FC-AL Cut-Through Switch The CTS 20x4G is designed to interface directly to Fibre Channel disk drives in a storage array. It can interface directly to optics or to cables at the ingress/egress .. point of an enclosure and is able to determine if an ining frame is destined for a drive within that enclosure.
