v Redundant connection
The addition of an optional Ethernet daughter card provides failover capability to
a redundant Ethernet connection with the applicable application installed. If a
problem occurs with the primary Ethernet connection and the optional Ethernet
daughter card is installed on the server, all Ethernet traffic that is associated with
the primary connection is automatically switched to the optional redundant
Ethernet daughter card connection. If the applicable device drivers are installed,
this switching occurs without data loss and without user intervention.
v Redundant cooling and optional power capabilities
The server supports a maximum of two 675-watt hot-swap power supplies and
six hot-swap fans, which provide redundancy and hot-swap capability for a typical
configuration. The redundant cooling by the fans in the server enables continued
operation if one of the fans fails. The server comes with one 675-watt hot-swap
power supply and five fans. You can order the second optional power supply with
the additional fan.
v RAID support
The RAID adapter provides hardware redundant array of independent disks
(RAID) support to create configurations. The standard RAID adapter provides
RAID levels 0, 1, and 1E. An optional RAID adapter is available for purchase that
provides RAID levels 0, 1, 5, 6, 10, 50, and 60.
v Systems-management capabilities
The servers comes with an Integrated Management Module (IMM). 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
system-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 TCP/IP offload engine (TOE) support
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: The Linux operating system does not support TOE.
v Preboot diagnostics program
The preboot diagnostics programs are stored on the integrated USB memory.
They collect and analyze system information to aid in diagnosing server
problems. The diagnostic programs collect the following information about the
server:
– System configuration
– Network interfaces and settings
– Installed hardware
– EasyLED status
– Service processor status and configuration
– Vital product data, firmware, and UEFI (formerly called BIOS) configuration
– Hard disk drive health
– RAID controller configuration
– Event logs for RAID controllers and service processors
