Reliability, availability, and serviceability features
Three of the most important considerations in server design are reliability, availability,
and serviceability (RAS). The RAS features help you to ensure the integrity of the
data that is stored on your server, the availability of the server when you need it, and
the ease with which you can diagnose and repair problems.
The following is an abbreviated list of the RAS features that your server supports:
• Power-on self-test (POST)
• Automatic restart after a power failure
• Low-voltage protection
• Dual hot-swap LVDS SCSI hard disk drives
• Error checking and correcting (ECC) memory
• Error codes and messages
• Menu driven setup, system configuration, and diagnostic programs
• System-management capabilities
• Redundant and hot-swap fans
• Redundant and hot-swap power supplies
• Diagnostic LEDs
