Reliability, availability, and serviceability features
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
stored on your blade server; that your blade server is available when you want to
use it; and that should a failure occur, you can easily diagnose and repair the failure
with minimal inconvenience.
The following is a list of some of the RAS features that your blade server supports:
v Advanced Configuration and Power Interface (ACPI)
v Automatic error retry or recovery
v Automatic server restart
v Built-in monitoring for temperature, voltage, and hard disk drives
v Chipkill memory
v Customer-upgradeable basic input/output system (BIOS) code
v Customer support center 24 hours per day, 7 days a week
v Diagnostic support of Ethernet controllers
v Error codes and messages
v Error correcting code (ECC) protection on the L2 cache
v ECC memory
v Failover Ethernet support
v Hot-swap drives on optional SCSI storage expansion unit
v Light Path Diagnostics feature
v Power-on self-test (POST)
v Predictive Failure Analysis (PFA) alerts
v Processor serial number access
v Service processor that communicates with the BladeCenter management module
v SDRAM with serial presence detect (SPD) and vital product data (VPD)
v System error logging
v Vital product data (VPD) (includes information stored in nonvolatile memory for
v Wake on LAN capability
2. Service availability will vary by country. Response time will vary depending on the number and nature of incoming calls.

BladeCenter HS20 Type 8678: Installation and User's Guide
automatically selects between 10BASE-T and 100/1000BASE-TX environments.
Each controller provides full-duplex (FDX) capability, which enables simultaneous
transmission and reception of data on the Ethernet local area network (LAN). The
controllers support Wake on LAN
Your blade server comes with two connectors on the system board for I/O
expansion options, such as the IBM HS20 Fibre Channel Expansion Card, for
adding more network communication capabilities to the blade server.
