PM8379 CTS 20x4G

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 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 perfor-mance.

The CTS 20x4G provides unique disk isolation 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.
