Binary compatibility across PA-RISC
You can continue to rely on binary compatibility across the PA-RISC family, enabling seamless interoperability with legacy applications on HP systems. Binary compatibility protects your investments, enabling rapid growth and adoption of new technology infrastructures. For performance improvements, you can use existing applications and operating systems with new or more advanced processor technology as it develops.
Binary compatibility for the Intel Itanium Processor Family
HP will continue to support binary compatibility through the introduction of Itanium-based systems. As a result of HP’s work with Intel on Explicitly Parallel Instruction Computing (EPIC) architecture—the technology foundation for the Intel Itanium architecture—today’s HP-UX, Windows, and Linux applications from their PA-RISC and x86 heritage will run unchanged on Itanium-based systems. To provide the best performance, you can recompile applications without source changes.
Upgrading an HP Integrity Superdome with Intel Itanium 2 processors to take advantage of the HP mx2 Dual-Processor Module
Upgrading an existing Integrity Superdome is quick and easy:
Remove the cell boards.
Replace the existing processors with new mx2 Dual-Processor Modules.
Plug the cell boards back into the cabinet.
The Intel Itanium 2 processors and mx2 Dual-Processor Modules can coexist in the same complex in different partitions. As such, processor upgrades can occur on a cell-board basis and can be performed one nPartition at a time in order to decrease downtime for the entire complex.
Upgrading an HP 9000 Superdome
Upgrading an existing HP 9000 Superdome is simple:
Remove the cell boards.
Transfer all memory to the new cell board.
Plug the cell board and the separate power board into the cabinet.
Replace existing cell blockers if the upgraded system requires cell blockers.
Replace side panels on the system cabinet if the upgraded system is going to be used with an I/O
Change system cabinet skins and I/O expansion cabinet skins to the graphite color.
Note: The original HP 9000 Superdome cells and HP Integrity Superdome cells cannot coexist in the same system, even in different partitions.
Processor upgrades occur on a cell board basis and can be performed one nPartition at a time in order to decrease downtime for the entire complex. You can upgrade PA-8600, 750 MHz PA-8700, and 875 MHz PA-8700 processors in this manner. (Mixing PA-RISC and Intel Itanium processors in one system is currently not supported.)
Today’s HP Integrity Superdome line is already prepared for the next generation of processors, ensuring that it will stay ahead of tomorrow’s performance demands. Integrity Superdome servers deliver investment protection through in-chassis upgrades.
