HP Integrity Superdome and 9000 Superdome sx2000 Server Configurations, Basic Configuration Rules

Figure 1-16 PA-RISC Firmware Interfaces

PA-RISC System Firmware Functions

•Supports only HP-UX

•Supports mixing of PA-RISC and Itanium cell boards in the same complex but in different partitions

•Detects and rejects Itanium cell boards mixing in a partition with PA-RISC cell boards

•Support all system management tools available with sx1000 systems

•FRU isolation and event ID reporting as enabled by the hardware and manageability firmware

•Cell OLAD (COLAD) of cells with noninterleaved memory. PA-RISC I/O card OLAD support requirements and design are the same as on sx1000 systems.

•Support for link level retry with self-healing for crossbar and I/O links

•Maximum of eight processor cores per cell board, based on NVM part size of 12 MB

•Supports two processors per CPU module

•Supports mixing of specific processor versions after they are identified as being compatible by the program

•Dual-core configuration, deconfiguration. Support for 1, 2, and 4 GB DDR-II DIMMs

•Support for mixed DIMMs on a cell

•Support for nonuniform memory configurations within a partition and address parity checking on DIMMs (no address ECC)

•Support for configuring and deconfiguring DIMMs in increments of two

•Enforcement of DIMM loading order

•PCI-X 2.0 (266 MHz) based I/O attach (PCI compatible)

•Support for all PCI-X and PCI cards supported by respective sx1000 systems

•Support for I/O slot doorbells and latches

•Elimination of Superdome core I/O card for Superdome/sx2000 console
