Was created to bridge the VPX standards to the space market.
•
•
•
SpaceVPX addresses both interoperability (as OpenVPX does) and space
application needs (not in OpenVPX).
SpaceVPX defines Payload, Switch, Controller, and Backplane module
profiles to meet needs of space applications
SpaceVPX adds features to the Utility Plane for fault tolerance
• Point-to-point not bussed to tolerate faults: failure on module does not affect
entire system.
• Space Utility Module added to provide dual-redundant source for Utility Plane
implementations.
•
SpaceVPX defines use of SpaceWire for Control Plane over Ethernet
(OpenVPX preferred solution).
Designed to promote standard components, interoperability, accelerated
development and deployment for the Space market

Fault tolerance enhancements needed for space
• No fault detection on critical configuration signals
•
Power distribution is not redundant
• Opportunity for single-point faults
•
Bused management signal distribution
• Opportunity for single-point faults
•
Individual Card level power and reset controls not addressed
• Limits ability to create architecture with standby powered-off spare modules

•
Choosing the most appropriate mechanism for introducing dualredundant Utility and Management planes was critical to meeting
SpaceVPX requirements.
• Several critical SpaceVPX requirements established a need for dualredundant Utility and Management planes in the architecture.
• Single-point failure tolerance
• Spare module support (redundancy)
• System management
• Status and diagnostic support
• The desire to maintain compatibility with existing COTS OpenVPX
modules was also a significant factor in selecting the redundancy
mechanism.

This section details how to specify a 6U Standard Chassis configuration. Additional
chassis mechanical characteristics are defined in Section 4. Due to the number of
possible chassis / backplane configurations, a 6U Standard Chassis Profile is defined
using a name constructed from the permitted options listed below.
 Rule 13.2-1: SpaceVPX 6U Standard Chassis Profiles shall be specified using the
construct per Figure 13.2-1 and associated parameters. [VM = I]
 Observation 13.2-1: The 6U Standard Chassis Profiles are based on the power
profiles.
 Observation 13.2-2: If SpaceVPX modules are plugged into standard chassis
slots with a smaller pitch, an adjacent slot will not be accessible.
 Observation 13.2-3: Smaller pitch SpaceVPX modules may be plugged into
larger pitched chassis slots.

These Backplane Profiles are intended for the development, prototyping, and
flight environment. The use of signals that are routed to the RTMs or to a
connectors is up the implementation.
Note: It is up to the RTM implementation whether it connects to these signals
and what is done with them.
Backplane Profiles include channel Gbaud rates, for the supported planes; a
system integrator needs to make sure the rated Gbaud rates, for the supported
planes, are high enough to support the Gbaud rates of the protocols of the
modules being used.
 Note: SpaceWire data rates may be higher than what is shown as each link will
negotiate the data rate.

The goal of SpaceVPX is to achieve an acceptable level of fault tolerance while
maintaining reasonable compatibility with OpenVPX components, including connector
pin assignments. For the purposes of fault tolerance, a module is considered the
minimum redundancy element. The Utility Plane and Control Plane are distributed
redundantly and in star topologies to provide fault tolerance.
For Space applications, the major fault tolerance requirements are listed below:











Dual-redundant power distribution (bussed) (Section 3.2.1) where each distribution is
supplied from an independent power source.
Dual-redundant management distribution (point-to-point cross-strapped) where each
distribution is supplied from an independent System Controller
SpaceVPX introduces the SpaceUM module that selects between the A and B Power
Supplies and the A and B System Controllers for distribution to each of the slots
controlled by the SpaceUM module.
Card-level serial management (Section 3.4.3)
Card-level reset control
Card-level power control
Timing/synchronization/clocks, matched length, low-skew differential (Section 3.4.2)
Fault tolerant Power Supply and System Controller selection (bussed) (Section 3.3)
Dual-redundant Data planes (point-to-point cross-strapped)
Dual-Redundant Control planes (point-to-point cross-strapped) (Section 3.2.3)
VITA 78 infrastructure allows for fully managed FRUs and for dumb FRUs

The Utility Plane in a SpaceVPX backplane differs from the OpenVPX Utility
Plane.
The OpenVPX Utility Plane includes bused power distribution rails, bused
control/status signals, and bused reference clocks.
The SpaceVPX Utility Plane replaces the bused OpenVPX Utility Plane with
redundant (A and B) utility planes and selects the active Utility Plane for each
individual slot.
The OpenVPX maximum number of slots is constricted by the number of 0.8”
slots in a 19 inch development chassis.
 Because SpaceVPX does not require the use of 19 inch development chassis, the
slot restrictions of OpenVPX are relaxed.

System Management Protocol




The System Management Architecture consists of three logical levels of
management: system, chassis and module.
The focus of the System Management Protocol is on the communications
between the Chassis Manager and the SpaceVPX Modules of the chassis. That
portion of the Chassis Manager that provides the lower level communications
functions within a chassis is referred to as the Chassis Management Controller
(ChMC).
The Space Utility Management (SpaceUM) Module, provides the Intelligent
Platform Management Bus (IPMB) selection and routing function for the radial
(star) topology between the ChMC and individual non-SpaceUM SpaceVPX
modules.
The collection of resources dedicated to module management is called the
Intelligent Platform Management Controller (IPMC). The communications bus
used by the ChMC to communicate with the IPMCs within a chassis is the
Intelligent Platform Management Bus (IPMB).
7/17/2015
37





The SpaceVPX IPMB has a radial topology, meaning that it forms a point-to-point
communications link between the ChMC and each IPMC.
The Management Plane Fan-out and Hub functions located on the SpaceUM
module support the connection of each redundant bus to the multiple IPMBs for
communications to each IPMC.
The management communications protocol supported by an IPMC may be one
of two possible protocols: Intelligent Platform Management Interface (IPMI)
Protocol or Direct Access Protocol.
The IPMI command structure is a multi-master I2C communications protocol
defined in [IPMI1D5]. The Direct Access command structure is a single-master,
address mapped communications protocol defined specifically by SpaceVPX.
Both of these protocols provide the same data structures from using different
communications protocols.
7/17/2015
38
Direct Access Protocol
The Direct Access Protocol offers an alternate communications protocol for
SpaceVPX modules. It is based on a set of registers that are mapped into the
Management Space accessible using a local address. The base address of the
register set is defined in Section 3.8.1.3.1 of the specification. The Management
Space Registers contain the same information available using the IPMI Protocol.
 The Direct Access Protocol allows communication between SpaceVPX modules
over the IPMB using the I2C Protocol defined in [I2C]. Data transfers involve a
master performing requests and a slave responding to the request.

Space Utility Management (SpaceUM) Module
The SpaceVPX SpaceUM module provides the selection function for the dualredundant Utility Plane distribution. By incorporating these functions in the
SpaceUM module, SpaceVPX provides compatibility with existing OpenVPX
capabilities and implementations.
 Note that although the SpaceUM module is an integral part of the SpaceVPX
power distribution system, it is not a power supply and does not include power
isolation capability. Implementers that choose to provide power isolation in the
SpaceUM module are exceeding the scope of this specification.

A fourth candidate is under development (IEH Corp.); however, the
product is nascent.
The SpaceVPX (VITA 78) did not make a connector recommendation.
Insufficient information largely the reason for a “No Go” on a
recommendation.

Configurations limited by either switch, controller or payload considerations
Direct backplane to external data or control connections will reduce payload slots
Direct switch to switch across the backplane will reduce payload slots

Each of the interconnect planes defined by OpenVPX are
supported by SpaceVPX as fully cross-strapped single-fault
tolerant capable
• Control, Data and Expansion plane redundancy is provided
using the existing OpenVPX connectivity
• Ability to utilize M-of-N payload module redundancy to
support either higher reliability or degraded modes of
operation
• The SpaceVPX Utility plane redundancy is a major departure
from OpenVPX
• OpenVPX uses single-source, bused power distribution
• OpenVPX uses single-source, bused clock, reset and
management distribution
• Each interconnect plane can be implemented with reduced fault
tolerance when desired
7/17/2015
59
•
Three concepts developed
• Concept 1 – Redefine an existing OpenVPX connector block as a second Utility
plane block (similar to P0/P1)
• Incompatible with existing OpenVPX modules
• Concept 2 – Extend the existing Open VPX connector by adding a second
Utility plane block (P7/P8 similar to P0/P1)
• Extends module height from 6U to 6U+TBD
• Partially compatible with existing OpenVPX modules
• Concept 3 – Add one or more Space Utility Management (SpaceUM) modules
with independent support for each OpenVPX module
• The SpaceUM module receives redundant Utility Plane signals through the
backplane and selects one set to be forwarded to the OpenVPX module
Utility Plane signals
• Allows use of existing OpenVPX modules in appropriate flight applications
7/17/2015
60
•
Architecture
• Provides single-fault-tolerance with limited increase in SWaP
• One SpaceUM module supports eight VPX slots
• Scalable to very large units
• Maximum of 31 VPX slots and 4 SpaceUM slots
• Dual-redundant power distribution
• Allows traditional space methods
• Dual-redundant management distribution
• Traditional capability using improved methods
• Accommodates supplier-preferred methods for implementing
•
interoperable products
Topology
• Traditional tree-topology is familiar to space suppliers
• Flexible command/status interface options allow tailoring to customer
needs

•
Leverages the VITA 46.11 industry standard
• Limited subset to minimize complexity
Defines an alternative light-weight protocol for less complex systems
Basic functions supported
• Individual module power on-off control
• Individual module reset control
• Individual module status monitoring
Advanced capabilities
• Module-level telemetry acquisition
• Voltage, temperature, digital state, etc.
• Module-level functional control
• Sub-function power control, register access, memory access, etc.

Infrastructure – power and management
• Dual-redundant with cross-strapping
• Single-string is a trivial subset
Backplane interconnect
• At least dual-redundant with cross-strapping
• Higher levels of redundancy are feasible
