HP rp7405/rp7410 N4000 N-Class servers are up to 8-way multiprocessing servers which could be hardware-partitioned into logical servers, two nPartitions. Based on the same 10U rack chassis as rp7400/N4000, these newer rp7405 and rp7410 have a completely overhauled system and I/O architecture.

The Core Electronic Complex is a modified HP Superdome cell system architecture for two cells with each up to four processors, sixteen RAM slots and central chipset.

rp7405 were apparently an entry-level version of rp7410, based on the same hardware with the same capabilities but shipped in smaller configurations. Upgrades to a full rp7410 were possible, probably with a modified firmware for unlocking.

System architecture

Processors

rp7405 and rp7410 support two to eight processors, based on their system board, designated by the [-6X, -7X … -9X] suffix.

System buses

Memory

Expansion slots

There are up to 16 PCI 64-bit/66 MHz slots in the I/O cage, which can be fully accessed when using a system with two cells. With one cell board only seven slots are available. One PCI slot is dedicated to Core I/O card set.
