HP Integrity rx2660 Server User Service Guide

Office Friendly Server Power
The Office Friendly server has two power supplies in the standard configuration. The server is
designed to provide high availability with 1+1 redundancy. However, the server runs more quietly
and efficiently with two power supplies installed. The AC/DC power supplies generate 12 VDC
for the server and peripherals, and a housekeeping voltage (+3.3 V standby). Each power supply
receives AC power through integrated AC inlets. The system can operate at 100 or 240 VAC.
The power supplies are power-factor corrected, and the maximum DC power output of each power
supply is 900 watts at 120 VAC, and 1000 watts at 240 VAC.
Mass Storage
The server mass storage subsystem contains the following major components:
• Small form factor (SFF), 2.5 in. serial-attached SCSI (SAS) hard drives with the following
supported capacities:
◦ 36 GB
◦ 73 GB
◦ 146 GB
• SAS cables
• SAS backplane
• SAS HP Smart Array P400 controller card, power cable, and battery (optional)
The server supports up to eight SAS hard drives. Each drive is equipped with LEDs that indicate
activity and device status.
The SAS drives connect directly into the SAS backplane. Two cables connect the SAS backplane
to the integrated SAS core I/O on the system board. Optionally, these cables connect to the SAS
Smart Array P400 controller card installed in a private PCIe slot on the system board.
Firmware
Firmware consists of many individually linked binary images that are bound together by a single
framework at run time. Internally, the firmware employs a software database called a device tree
to represent the structure of the hardware platform and to provide a means of associating software
elements with hardware functionality.
The firmware incorporates the following main interfaces:
• Processor Abstraction Layer (PAL). PAL provides a seamless firmware abstraction between the
processor and system software and platform firmware.
• System Abstraction Layer (SAL). SAL provides a uniform firmware interface and initializes and
configures the platform.
• Extensible Firmware Interface (EFI). EFI provides an interface between the operating system
and the platform firmware. EFI uses data tables that contain platform-related information, and
boot and runtime service calls that are available to the operating system and its loader to
provide a standard environment for booting.
• Advanced Configuration and Power Interface (ACPI). ACPI provides a standard environment
for configuring and managing server systems. ACPI moves system power configuration and
management from the system firmware to the operating system and abstracts the interface
between the platform hardware and the operating system software. This enables each to
evolve independently of the other.
The Data Center server firmware supports the HP-UX 11i version 3, February 2007 release, Linux,
Windows, and OpenVMS 8.3 operating systems through the Itanium processor family standards
and extensions, and has no operating system-specific functionality included.
