VITA 46.11 defines a framework for System Management in VPX systems
based on the Intelligent Platform Management Interface (IPMI)
specification developed by the Intel Corporation and others in the
VITA 46.11 leverages the work done in the development of the
AdvancedTCA® (ATCA) specification by PICMG®. Within the ATCA
specification, PICMG specified an IPMI-based implementation to aid
in the management of their next generation specifications based
module form factors and Chassis.
Where appropriate this standard discusses similarities and
differences between the VITA 46.11 and the ATCA implementations.
Readers who are familiar with the ATCA specification should find
these comparisons helpful in understanding how IPMI has been
implemented in VITA 46.11. Readers may also find it helpful, and at
times necessary, to refer to the PICMG® specification to better
understand the genesis behind an ATCA-leveraged implementation
detail or concept or to better appreciate the differences between
the two specifications based on the markets each serves.
VITA 46.11 extends the multi-plane architecture of the VITA 46.0
family of standards by defining an IPMI based management plane onto
the VITA 46.0 connector pins and defining an overarching System
Management architecture for VITA 46.0 products.
1.1 VITA 46.11 Objectives
The objectives of this standard are:
• Define a standardized System Management architecture for VPX
• Assign System Management interfaces to the VPX P0/J0 connector
• Enable System Management interoperability at FRU, Chassis, and
• Leverage existing commercial System Management solutions
• Provide System Management features that meet the VPX market needs
• Create a scalable solution space of proportional capabilities and
• Specify a separate infrastructure for the purpose of System
