System Overview

PDSi's new SATA XMC Storage Module (XMC-SD18) offers high capacity SATA storage using compact 1.8 inch hard disk or solid state drives providing up to 160GB of storage. The on-board 4 port SATA controller provides an additional drive interface through the front connector. Two more drives can be controlled through the rear I/O (Pn4) connector.

Whether configured with an economical rotating HDD or highly shock-resistant SSD, this low profile module fits comfortably into VITA 42.3 compatible VME, CompactPCI®, AdvancedTCA®, and other processor boards with an XMC mezzanine card interface. This board meets all XMC height restrictions, especially when configured with a solid state drive.

Military applications will appreciate the high operating shock resistance (1000+ G) and high MTBF (over 1 million hours) when configuring this XMC with the latest solid state drive technology. PDSi will adapt this design for other I/O requirements and can develop compatible rear I/O boards if needed. Extended availability from PDSi is assured. PDSi can also provide integration, extended warranty, global repair and support services.
