PICMG 3.2 R1.0P

The PICMG 3.2 Specification is a member of the PICMG 3.0 AdvancedTCA™ series of specifications. The base specification in the family, PICMG 3.0, defines a Board and Shelf architecture for modular computing and communications components. The Boards share a common Backplane for point-to-point differential connectivity that supports many common high-speed switched fabric technologies. PICMG 3.2 specifies the usage of InfiniBand® over this backplane fabric.
Objectives

The specification in this document is wholly derived from, and is dependent upon, the PICMG 3.0 Base Specification. It is not intended to stand alone or to be used separately from the Base Specification.
PICMG 3.2 builds upon the PICMG 3.0 Base Specification and the InfiniBand Specifications to meet the following objectives:
• Define how InfiniBand signaling is to be used over the Fabric Interface defined in the PICMG 3.0 Specification.
• Provide guidelines for the use of 1X, 4X, and 12X InfiniBand links
• Provide guidelines for the use of InfiniBand in-band management
• Provide recommendations and guidelines for utilization of advanced InfiniBand features that increase performance and interoperability

The guidelines and design rules set forth in this specification shall be consistent with the applicable sections of the InfiniBand Specification version as referenced in Section 1.3 of this document. PICMG 3.2 products will comply with InfiniBand Signal, Link, Transport, and Management layers in order to maximize interoperability with other InfiniBand hardware and software products.
