SHB Express

• Why SHB Express?
• Parallel bus architectures are causing data
  bottlenecks in high-performance systems
• Faster processors
• Faster option cards
• Faster chipsets and system busses
• Chipsets no longer offer native support for ISA
• Chipsets are migrating toward PCI Express
• Need a faster way to get option card data to and
  from the system host board
• Need better host board power management and
  simplified I/O cabling
• Must support PCI Express, PCI and PCI-X option
  cards
• Need seamless support of existing system software
  and device drivers

SHB Express

• SHB Express Improves Upon Previous PICMG 1.0
  and PICMG 1.2 specifications
• Same basic mechanical dimensions are maintained
  to minimize chassis redesign expense
• PCI Express SHB-to-backplane serial interfaces
  replace the PICMG 1.0 1.2 parallel interfaces
• Full PCI and PCI-X option card support is
  maintained with limited ISA card support possible
• Enables a fast, simple and cost-effective
  transition to SHB Express
• Additional power pins added to the edge
  connectors eliminate the need for auxiliary power
  connectors
• SHB hold down area is defined for full-size
  system host boards
• Newer power supply functions such as wake/sleep
  modes, soft system starts, etc. are now supported
• Optional I/O routings to the backplane are
  available to help reduce the number of cable
  connections to the SHB

Spec. also provides PCI Express Gen 2 and
Advanced Switching support
