The Ethernet controllers in the server support TOE, which is a technology that
offloads the TCP/IP flow from the microprocessor and I/O subsystem to increase
the speed of the TCP/IP flow. When an operating system that supports TOE is
running on the server and TOE is enabled, the server supports TOE operation.
See the operating-system documentation for information about enabling TOE.
Note:
As of the date of this document, the Linux operating system does not
support TOE.
Reliability, availability, and serviceability
Three important computer design features are reliability, availability, and
serviceability (RAS). The RAS features help to ensure the integrity of the data that
is stored in 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:
v
1-year parts and 1-year labor limited warranty for machine type 4251, 3-year
parts and 3-year labor limited warranty for machine type 4252, and 4-year parts
and 4-year labor limited warranty for machine type 4261.
v
Automatic error retry and recovery
v
Automatic restart on nonmaskable interrupt (NMI)
v
Automatic restart after a power failure
v
Advanced Configuration and Power Interface (ACPI)
v
Advanced Desktop Management Interface (DMI) features
v
Intelligent Platform Management Interface (IPMI) 2.0 support that provides secure
remote power on/power off and seven standard alerts for components such as
fans, voltage, and thermals
v
Auto-restart initial program load (IPL)
v
Boot-block recovery
v
Built-in, menu-driven configuration and setup programs
v
Backup basic input/output system switching under the control of the integrated
management module (IMM)
v
Built-in monitoring for fan, power, temperature, voltage, and power supply
v
Diagnostic support for ServeRAID and Ethernet adapters
v
ECC memory
v
Error codes and messages
v
Hot-swap hard disk drives
v
Integrated management module (IMM)
v
Menu-driven setup, system configuration, and redundant array of independent
disks (RAID) configuration programs
v
Parity checking on the small computer system interface (SCSI) bus and PCI
buses
v
Power management: Compliance with Advanced Configuration and Power
Interface (ACPI)
v
Power-on self-test (POST)
v
Predictive Failure Analysis (PFA) alerts on memory, SAS/SATA hard disk drives,
fans, and power supplies
v
Remote system problem-determination support
v
Read-only memory (ROM) checksums
v
ROM-based diagnostics
v
SDRAM with serial presence detect (SPD)
v
Serial Presence Detection (SPD) on memory, VPD, power supply, and hard disk
drives backplane
v
Single-DIMM isolation of excessive correctable error or multi-bit error by the
Unified Extensible Firmware Interface (UEFI)
