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 protect unauthorized access to the server (see “Using passwords” on page 57)

–ThinkServer Trusted Platform Module (TPM), which is a security chip, to help enhance server security Note: The TPM is only available in some models.

–Remote monitoring or control by an administrator to provide protection or help

–Hot-swap redundant power supplies to help avoid significant interruption to the operation of the system when a power supply fails

–Six hot-swap system fans with redundancy, which means that five system fans can provide adequate cooling while the extra one serves as a redundant system fan, to help you to avoid significant cooling problems when a system fan fails

•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 53.
