server, you can manage the functions of the server locally and remotely. The
IMM2 also provides system monitoring, event recording, and network alert
capability.
v TCP/IP offload engine (TOE) support
The Ethernet controller 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. The Windows operating system requires that the Windows
Scalable Network Pack (SNP) be installed for TOE support.
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 Advanced Configuration and Power Interface (ACPI)
v Advanced Desktop Management Interface (DMI) features
v Automatic BIOS recovery to a backup image
v Automatic error retry or recovery
v Automatic memory downsizing on error detection
v Automatic restart on nonmaskable interrupt (NMI)
v Automatic Server Restart (ASR) logic supporting a system restart when the
operating system becomes unresponsive
v Automatic server restart after a power failure, based on the UEFI setting
v Availability of microcode level
v Boot-block recovery
v Built-in, menu-driven setup, system configuration, and redundant array of
independent disks (RAID) configuration
v Built-in monitoring for fan, power, temperature, and voltage
v Cooling fans with speed-sensing capability
v Customer support center that is available 24 hours a day, 7 days a week
2
v Diagnostic support of ServeRAID adapters
v Error codes and messages
v Error correcting code (ECC) double-data-rate 3 (DDR3) synchronous dynamic
random-access memory (SDRAM) with serial presence detect (SPD)
v Error logging of POST failures
v Simple-swap Serial ATA (SATA) hard disk drives
v Integrated Ethernet controller
v Intelligent Platform Management Interface (IPMI)
v Key-lock support for physical security
v Memory change messages posted to the error log
v integrated management module II (IMM2)
v Power management
v Power-on self-test (POST)
v Read-only memory (ROM) checksums
v Redundant Ethernet capabilities (requires an optional Ethernet adapter) with
failover support
v ROM-based diagnostic programs
2. Service availability will vary by country. Response time varies; may exclude holidays.
