MTPDK144 Switch PDK

Overview

The MTPDK24 and MTPDK144 Production Development Kits (PDK) are complete sets of files that enable OEMs to rapidly manufacture and deliver high-performance InfiniBand switches with a number of different configurations.

The modular switch design specified in the MTPDK144 is based on multiple InfiniScale III switch ICs and a mid-plane chassis design with two spine boards and up to twelve leaf boards.

The 10U chassis design can be mounted in the back of a 19” rack with the InfiniBand ports facing outward. Twelve switch leaf boards (either 12-port 4X or 4-port 12X) plug into the chassis for InfiniBand fabric connectivity. Air flow enters from the spine board/fan tray side and exits through the I/O ports. The chassis includes integrated fan modules and dual -48VDC power feeds from two hot swap 1+1 redundant power supplies (optional).

The MTPDK144 also includes design information necessary to build any configuration of 4X or 12X leaf boards which connect to either a 4X or 12X spine. The 4X spine boards provide switching between multiple 4X leaf boards for 12, 24, 36...144 4X port switch configurations. The 12X spine boards provide switching between multiple 12X leaf boards for 4, 8, 12...48 12X port switch configurations. The 12X spine boards are also capable of supporting 4X leaf boards. The backplane passively connects them all together in a Full Bi-Sectional Bandwidth topology.
