5.3.1 Persistent memory
The Blade supports a persistent memory. The persistent memory (PMEM Module) is an array of
random access memory that preserves its contents during a payload reset. The memory is
mapped into the memory address range of the CPU. Persistent memory is a necessary
prerequisite for performing postmortem analysis of log data after reset and reboot of the
payload CPU.
5.4 Chipset
The Intel 5520 chipset provides access between the two processors and the I/O subsystem. The
chipset provides up to 36 PCI Express generation two lanes. The Blade makes use of 5 times four
PCIe lanes routed to the Zone 3 connector.
The chipset is connected to the ICH10R I/O Controller via the Enterprise South Bridge Interface
(ESI).
5.5 I/O Controller
The ICH10R provides extensive I/O interface support and the BOOT path to SPI Boot Flash
devices for the processor. ICH10R is connected to the system through the Enterprise
Southbridge Interface (ESI) of the Xeon 5520 chipset.
The following is a list of the main internal features and the I/O interface functions provided by
the ICH10R Southbridge.

Six x4 PCI Express 1.1 Interface

LPC interface

SPI Interface (Boot Flash): up to two devices 20 + 33 MHz

Six serial ATA (SATA) interfaces (2 used on ATCA-7360)

Twelve USB 2.0 interfaces (4 used on ATCA-7360)

Two 8259 Interrupt Controllers and I/O APIC controllers

Integrated I/O APIC

Power management support
