Reliability, availability, and serviceability features

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 repair problems.
The server has the following RAS features:
v Automatic error retry and recovery
v Automatic restart after a power failure
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
v Cable-presence detection on most connectors
v Chipkill memory protection
v Dual redundant UEFI server firmware images
v Error codes and messages
v Error correcting code (ECC) L2 cache and system memory
v Cooling fans with speed-sensing capability
v Hot-swap hard disk drives (for servers that support such drives)

The IMM2 provides failover capability to a redundant Ethernet connection with
the applicable application installed. If a problem occurs with the primary Ethernet
connection, all Ethernet traffic that is associated with the primary connection is
automatically switched to the optional redundant Ethernet connection. If the
applicable device drivers are installed, this switching occurs without data loss and
without user intervention
The server supports a maximum of two 550-watt or 750-watt hot-swap power
supplies and three dual-motor non hot-swap fans, which provide redundancy 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 550-watt
or 750-watt hot-swap power supply and three non hot-swap fans.
Note: You cannot mix 550-watt and 750-watt power supplies in the server.
The ServeRAID adapter provides hardware redundant array of independent disks
(RAID) support to create configurations. The standard RAID adapter provides
RAID levels 0 and 1. An optional RAID adapter is available for purchase.
The server comes with an integrated management module II (IMM2). When the
IMM2 is used with the systems-management software that comes with the server,
you can manage the functions of the server locally and remotely. The IMM2 also
provides system monitoring, event recording, and network alert capability. The
system-management connector on the rear of the server is dedicated to the
IMM2. The dedicated system-management connector provides additional security
by 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.
