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 Server Configurations See the HP System Partitions Guide for information about proper configurations. Basic Configuration Rules Single-Cabinet System: • Two to 32 CPUs per complex with single-core processors • Four to 64 CPU cores per complex with dual-core processors Server Configurations 47
