v Systems-management capabilities
The server comes with an Integrated management module 2.1 (IMM2.1). When
the IMM is used with the systems-management software that comes with the
server, you can manage the functions of the server locally and remotely. The
IMM also provides system monitoring, event recording, and network alert
capability. The systems-management connector on the rear of the server is
dedicated to the IMM. The dedicated systems-management connector provides
additional security by physically separating the management network traffic
from the production network. You can use the Setup utility to configure the
server to use a dedicated systems-management network or a shared network.
v UEFI-compliant server firmware
IBM System x Server Firmware (server firmware) offers several features,
including Unified Extensible Firmware Interface (UEFI) 2.1 compliance; Active
Energy Manager 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. UEFI-compliant System x
servers are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
Note: The server does not support DOS (Disk Operating System).
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. The USB
embedded hypervisor flash device can be installed in the internal USB connector
on the system board. For more information about using the embedded
hypervisor, see “Using the embedded hypervisor” on page 51.
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 5463)
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 Back up 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 Double-device data correction (DDDC) 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
v Error codes and messages
v Error correcting code (ECC) L3 cache and system memory
