1 Overview

The HP Integrity rx6600 server is a high performance, high availability server that provides the
following features:
Form factor - 7U rack- or pedestal installed
Internal peripherals - serial-attached SCSI (SAS) hard drives and a DVD or DVD+RW drive
High availability components - hot-swappable dual-rotor N+1 fans, 1+1 hot-swappable power
supplies, and hot-pluggable PCI-X or PCIe cards and SAS drives
Processors - up to four dual-core Intel® Itanium® processors
Memory - up to 384 GB of memory

Server Subsystems

I/O

The server may contain either a 10-slot PCI/PCI-X IOBP or a 10-slot PCI/PCI-X/PCIe IOBP. The
PCI/PCI-X/PCIe interfaces are classified under two major categories: public and private.
Public interfaces
Public interfaces are PCI slot connectors that are left available to the customer for the I/O-card
adapters which they wish to install, based on their application needs, provided the adapter is
supported in the slot. All public slots support HP server traditional OL* hot-plug operations.
Private interfaces
Private interfaces are interfaces dedicated to meeting the core I/O system requirements. There are
two types of core-I/O: fast-core and slow-core, also known as the UCIO (Unified Core-I/O). The
Private slots and UCIO are not hot-pluggable.
Hot-plug
PCI/PCI-X/PCIe hot-pluggable operations enable you to add or remove a PCI/PCI-X/PCIe card
while the server is powered on. Each slot is physically separated with a divider that contains a
card extraction mechanism and a mechanical retention latch (MRL). Slots 3 - 10 on the 10 slot
PCI/PCI-X IOBP and slots 5 - 10 on the 10 slot PCI/PCI-X/PCIe IOBP support HP-server traditional
OL* "hot-plug" operations. PDHP slots rely on the facilities of DHPC (Dual Hot-plug Controller)
FPGAs to enable OL* hot-plug functionality. See
LEDs
Attention LEDs, doorbell buttons, and power LEDs for each hot-pluggable PCI/PCI-X/PCIe slot are
located on the PCI bulkhead at the rear of the server chassis.
Wake on LAN
Wake on LAN, a hardware feature that enables the remote power on of computers through special
network packets, is enabled in core PCI/PCI-X slots one and two.
Ropes
Ropes is an HP-proprietary, custom bus interface. It clocks data packets across long-length nets
using source synchronous clocking schemes. There are eighteen signals bundled per Ropes group,
of which there are a total of 16 in the server. Each group is capable of 0.5GB/s peak bandwidth.
