IBM System x3750 M4 Type 8733, Installation And Service Manual

Page: 29 / 694

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.

UEFI-compliant server firmware
The UEFI firmware offers several features, including Unified Extensible
Firmware Interface (UEFI) version 2.1 compliance, Active Energy Management
(AEM) technology, enhanced reliability, availability, and serviceability (RAS)
capabilities, and basic input/output system (BIOS) compatibility support. UEFI
replaces the BIOS and defines a standard interface between the operating
system, platform firmware, and external devices. The server is capable of
booting UEFI-compliant operating systems, BIOS-based operating systems, and
BIOS-based adapters as well as UEFI-compliant adapters. For more information
about UEFI-compliant firmware, go to http://www.ibm.com/systems/support/
supportsite.wss/docdisplay?lndocid=MIGR-5083207&brandind=5000008.
Note: The server does not support DOS.
v
VMware ESXi embedded hypervisor
An optional USB flash device with VMware ESXi embedded hypervisor software
is available for purchase. Hypervisor is virtualization software that enables
multiple operating systems to run on a host system at the same time. Install the
USB flash device in the USB embedded hypervisor flash device connectors on
the system board (see “System-board internal connectors” on page 26). See
“Using the embedded hypervisor” on page 138 for additional information.
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
3-year parts and 3-year labor limited warranty (Machine Type 8722)
v
24-hour support center
v
Automatic error retry and recovery
v
Automatic restart on nonmaskable interrupt (NMI)
v
Automatic restart after a power failure
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
redundancy
v
Cable-presence detection on most connectors
v
Chipkill memory protection
v
Single-device data correction (SDDC) for x4 DRAM technology DIMMs
(available on 16 GB DIMMs only). Ensures that data is available on a single x4
DRAM DIMM after a hard failure of up to two DRAM DIMMs. One x4 DRAM
DIMM in each rank is reserved as a space device.
v
Diagnostic support for ServeRAID and Ethernet adapters
