Overview

The rp7405/rp7410 N4000 servers are up to 8-way multiprocessing servers and the smallest HP systems which can be partitioned into logical servers (two nPartitions). Based upon the same 10U rack-mountable chassis as their rp7400/N4000 brethren, the newer rp7405 and rp7410 are built around a completely overhauled system and I/O architecture. The Core Electronic Complex is a modified version of the Superdome’s cell-based system architecture, limited to two cells, which each contain up to four processors, sixteen memory slots and the central chipset — the cell controller (CC). These newer N4000s feature a very large amount of system and I/O bandwidth: 16GB/s CPU, 8GB/s memory, 8GB/s cell-to-cell and 8.5GB/s I/O bandwidth (all maximum aggregate &#118alues).

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

Introduced: 1999-2000

Internals

CPU

The rp7405 and rp7410 support from two to eight processors.

They are based on different system boards with different model numbers — the same basic architecture but with differences relating to the type and number of processors.

  • A6752A (rp7410) supports 650MHz, 750MHz and 875MHz processors

Processor types are indicated with the following suffixes:

  • -7X: PA-8700 750MHz with 768/1536KB on-chip I/D L1 cache each
  • Itanium 2/IA64 processors are probably also possible on some models
  • It is unclear which models support the -8X, -9X, PA-8900 and IA64 processors

There are two CPU/memory cell boards, with each four processor sockets.

Chipset

The Cell system architecture has three main components:

1.      Cell controller (CC): the central chipset and crossbar. One sits at the centre of each cell board for a maximum of two in a complete system. The CCs provide links for:

o        Four Processors (8.0GB/s)

o        Two Memory banks (4.0GB/s peak)

o        I/O via SBA (cell to I/O communication is 2.0GB/s peak)

o        PDH (processor dependent hardware) and firmware/flash etc.

o        Second cell via XBC (cell-to-cell communication is 8.0GB/s peak)

2.      Master I/O controller (SBA): the central I/O part of the main chipset. rp7405/rp7410 have two SBAs, located on the I/O backplane. Each is linked to one cell — with one cell board only one SBA and its I/O options can be used.

o        Each SBA provides sixteen 12-bit links (ropes) — the combined 32 (2×16) links/ropes from both SBAs connect to 18 slave I/O controllers (LBAs) which in turn connect the PCI I/O slots and Core I/O subsystems

o        28 ropes link to 14 Twin-Turbo slots (via 14 LBAs)

o        Two ropes link to two Turbo (that is, normal) PCI slots (via two LBAs), from which one is reserved for the PCI Core I/O LAN/SCSI card

o        Two links/ropes (one from each SBA) are connected via two LBAs to the Core I/O MP/SCSI card(s)

3.      Core I/O card set: provides the standard I/O functions for the system. One of these sets is the required minimum in any N4000, up to two Core I/O card sets are possible. Each Core I/O card set contains two distinct cards: MP/SCSI card, installed in a separate slot, and LAN/SCSI, installed in PCI slot (specially designated, I/O chassis 1, slot 8).

o        Two dual-channel Symbios Logic 53C1010 Ultra160 SCSI controllers (on MP/SCSI and LAN/SCSI)

o        Dual-channel Symbios Logic 53C896 Ultra2-Wide SCSI-3 controller (MP/SCSI)

o        Gigabit Ethernet networking (LAN/SCSI)

o        Diva Serial [GSP] Multiport UART for console (MP/SCSI), serial and management controllers (MP/SCSI)

o        Fast-Ethernet (DEC 21142/43) Management LAN (MP/SCSI)

o        The optional second Core I/O card set can be used either for redundancy or partitioning purpuses (I/O for the second partition)

Other parts of the chipset:

  • Prelude SMC memory controllers (on each cell board)
  • 18 Elroy PCI bridges (LBAs) convert the links/ropes from the SBA into PCI bus (only 9 of these 18 LBAs are used when only one cell board is installed)

Buses

  • Runway+/Runway DDR CPU bus (CPU to cell controller), 125MHz DDR, 64-bit wide, 2.0GB/s per CPU — aggregate 8.0GB/s for each cell (four CPUs/cell) and 16.0GB/s for maximum system
  • Memory bus (memory to cell controller) 4.0GB/s for each cell — aggregate 8.0GB/s for maximum system
  • XBC cell-to-cell link (cell controller to cell controller) 8.0GB/s aggregate
  • SBA cell-to-I/O link (cell controller to I/O backplane) 2.0GB/s on each cell — aggregate 4.0GB/s for maximum system
  • 32 I/O links/ropes, 12-bit wide, 265MB/s (16 links/ropes on each cell) — 8.5GB/s I/O aggregate peak bandwidth
  • 14 PCI-64/66 I/O buses for expansion slots
  • Two PCI-64/33 I/O buses for expansion slots (for Core I/O SCSI/LAN)
  • Two PCI-64/33 I/O buses for Core I/O (MP/SCSI)
  • Two SCSI-3 Ultra160 LVD main storage I/O buses (one on each cell)
  • Ultra SCSI SE for removable media (DVD/Tape)

Memory

  • ECC DIMMs, low-voltage TTL interface, 125MHz frequency (traditional/PC-133 SDRAMs do not work)
  • 256MB, 512MB and 1GB modules supported (2GB probably later too)
  • 16 slots on each cell board (32 slots maximum in a full system configuration), installed in quads
  • 32GB maximum (in a full system configuration with two cells)
  • 64GB was given as maximum with future memory modules — probably working today

Expansion

There are in all 16 PCI 64-bit/66MHz 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 the Core I/O card set (see above) so only 15 of the 16 PCI slots are available for expansion options.

  • 14 Twin-Turbo PCI 64-bit/66MHz slots, each on an independent PCI bus, each connected via two I/O links/ropes (aggregate 530MB/s), hot-plug capable
  • Two Turbo PCI 64-bit/66MHz slots, each on an independent PCI bus, each connected via one I/O link/rope (265MB/s), hot-plug capable (one of these two Turbo slots is reserved for Core I/O LAN/SCSI)
  • Twelve slots keyed for 3.3V (support either 3.3V or universal PCI cards)
  • Four slots keyed for 5.0V (support either 5.0V or universal PCI cards)

Drives

  • Four trays for low-profile 3.5″ Ultra2-Wide LVD SCSI hard drives with 80-pin SCA connector, hot-plug (two Core I/O card sets are needed to access all four drives)
  • One tray for a half-heigth 5.25″ 50-pin Ultra-Narrow SE SCSI drive, external accessible

The two pairs of SCSI drives are each connected to a separate channel on one of the SCSI controllers of the Core I/O sets — for both pair of drives to work two Core I/O card sets are needed.

External connectors

  • 68-pin VHDCI Ultra160 LVD external SCSI (external channel from LAN/SCSI board)
  • Three DB9 male RS232C serial (local console, remote console, UPS) via a DB25 M cable (MP/SCSI board)
  • 10/100Mbit Ethernet TP/RJ45 Management LAN (MP/SCSI board)
  • Gigabit Ethernet TP/RJ45 (LAN/SCSI board)

ROM update

There is an firmware update available which contains the latest version version 6.5.

  • PF_CKEYMAT0605.txt has details about the contents and installation of the patch.
  • PF_CKEYMAT0605.tar.gz contains the patch.
