Reliability, Availability, And Serviceability - IBM 6385 User Manual

Reliability, availability, and serviceability

Three important hardware and software design features are reliability, availability,
and serviceability (RAS). The RAS features help to ensure the integrity of the data
that is stored in the hardware, the availability of the hardware and software when
you need it, and the ease with which you can diagnose and correct problems.
The dx340 has the following RAS features:
v Advanced Configuration and Power Interface (ACPI)
v Advanced Desktop Management Interface (DMI) features
v Automatic error retry or recovery
v Automatic restart after a power failure, based on the BIOS setting
v Boot-block recovery
v Built in, menu-driven setup, system configuration, and redundant array of
v Built-in monitoring for fan, power, temperature, and voltage
v CD-based diagnostic programs
v Customer support center that is available 24 hours a day, 7 days a week
v Diagnostic support of ServeRAID adapters
v Error codes and messages
v Power-on self-test (POST) with error logging of POST failures
v Power management
v Hot-swap Serial Attached SCSI (SAS) hard disk drives (some configurations)
v Integrated Ethernet controller
v Read-only memory (ROM) checksums
v Redundant Ethernet capabilities with failover support
v Simple-swap Serial Advanced Technology Attachment (SATA) hard disk drives
v Simple-swap Serial Attached SCSI (SAS) hard disk drives (some configurations)
v Standby voltage for systems-management features and monitoring
v System-error LED on the front bezel
v Upgradeable BMC firmware
v Upgradeable microcode for POST, basic input/output system (BIOS) code, and
v Vital product data (VPD); includes firmware revision numbers, stored in
