Reliability, availability, and serviceability
Reliability, availability, and serviceability (hereinafter referred to as RAS) are three important server design
features. The RAS features help you to ensure the integrity of the data stored on the server, the availability of
the server when you need it, and the ease with which you can diagnose and correct problems.
Your server has the following RAS features:
• Security features
– Administrator password and user password to help you protect unauthorized access to the server
(see “Using passwords” on page 41)
– ThinkServer Trusted Platform Module (TPM), which is a security chip, to help enhance server security
Note: The TPM is only available in some models.
– Redundant Array of Independent Disks (RAID) configuration for improving data storage reliability and
fault tolerance (see “Configuring RAID” on page 47)
– Remote monitoring or control by an administrator to provide protection or help
• Basic system management features
– Ability to store the power-on self-test (POST) hardware test results
– BIOS Setup Utility program
The BIOS Setup Utility program helps you view the server information and configure the server in the
pre-operating system environment. See “Using the Setup Utility program” on page 37.
– Preboot Execution Environment (PXE)
The Intel PXE technology enables you to start your computers, load an operating system, or deploy
executable images from a remote server by using a network interface. The operation can be done
independently of local data storage devices (such as hard disk drives) or operating systems.
