Over the years Hewlett-Packard has developed a highly successful RISC processor line - the PA-RISC (Precision Architecture Reduced Instruction Set Computing) family, in addition to a highly robust and functional, Unix operating system - HP-UX. PA-RISC and HP-UX have been inseparable in Hewlett-Packard's award-winning, Unix workstations and high-end Unix servers (N-class, V-class, L-class, A-class). Hewlett-Packard's commitment and execution have been stellar.PA-RISC processors can be used in a myriad of configurations from uni-processor to 64 way multi-processors. Hewlett-Packard's enterprise solutions allow customers to configure their systems in SMP (Symmetric Multi-Processor) or ccNUMA (Non-Uniform Memory Access) formats, providing scalability and flexibility to customers.
