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.
- HP rp7405 N4000, A7111A, A7112A and A7113A, were introduced in 2002 for $50,959
- HP rp7410 N4000, A6752A, were introduced in 2002 for $92,250
System architecture
Processors
rp7405 and rp7410 support two to eight processors, based on their system board, designated by the [-6X, -7X … -9X] suffix.

Chipset
- HP Cell controller (CC), central chipset and crossbar, provides links for four processors, two memory banks, I/O via SBA, PDH and firmware, and second cell.
- HP Master I/O controller (SBA) on I/O backplane on each cell, provides up to 32 links that connect to slave I/O controllers LBA.
- Core I/O for I/O functions on two cards MP/SCSI and LAN/SCSI:
- Two dual-channel Symbios Logic 53C1010 Ultra160 SCSI controllers
- Dual-channel Symbios Logic 53C896 Ultra2-Wide SCSI-3 (MP/SCSI)
- Gigabit Ethernet networking (LAN/SCSI)
- Fast-Ethernet (DEC 21142/43) Management LAN (MP/SCSI)
- Optional second Core I/O card, for redundancy or partitioning
- 18 Elroy PCI bridges (LBAs) convert links/ropes from the SBA to PCI bus (only 9 of these 18 LBAs are used when only one cell board is installed)
