PM8379 Datasheet 20-port 4.25 Gbit/s Fc-al Cut-through Switch

Manufacturer: PMC-Sierra

Overview: 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 www.datasheet4u.com point of an enclosure and is able to determine if an incoming frame is destined for a drive within that enclosure. After determining which port is associated with the frames recipient, a cut through operation to that port is performed thereby significantly reducing system latency and improving performance.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

that significantly increase total system availability, reliability, and serviceability.
Built-in self test capability with FC Frame Generator/Comparator.
Supports a 106.25 MHz, 40-bit (20 receive + 20 transmit) DDR parallel interface that acts as a 21st port. This flexible interface enables external functions such as enclosure management or other user-proprietary functions to be implemented using a low cost FPGA. CUT-.
