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 65)
– Hot-swap redundant power supplies to protect against significant interruption to the operation of the
system when a power supply fails (for server models that come with one power supply, you can
purchase a hot-swap redundant power supply option from Lenovo and install it into your server as the
second power supply for redundancy)
– Redundant Array of Independent Disks (RAID) configuration for improving data storage reliability and
fault tolerance (see "Configuring RAID" on page 72)
– Remote monitoring or control by an administrator to provide protection or help
– ThinkServer Trusted Platform Module (TPM), which is a security chip, to help enhance server security
Note: The TPM is only available in some models.
• Basic system management features
– Ability to store the power-on self-test (POST) hardware test results
– BIOS Setup Utility program
