Three of the most important features in server design are
reliability, availability, and serviceability (RAS). These RAS features
help to ensure the integrity of the data that is stored in the blade
server, the availability of the blade server when you need it, and
the ease with which you can diagnose and correct problems.
The blade server has the following RAS features:
- Customer upgrade of flash ROM-resident code and diagnostics
- Power policy 24-hour support center
- Vital product data (VPD) on memory
- Processor presence detection
- Advanced Configuration and Power Interface (ACPI)
- Automatic server restart (ASR)
- Built-in diagnostics using DSA Preboot, which is
stored in integrated USB memory.
- Built in monitoring for temperature, voltage, and hard disk drives
- Customer support center 24 hours per day, 7 days a week.1
- Customer-upgradeable Unified Extensible Firmware Interface (UEFI)
