Reliability, availability, and serviceability

Three important server 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 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
The mini-BMC provides basic service-processor environmental monitoring
functions. If an environmental condition exceeds a threshold or if a system
component fails, the mini-BMC lights LEDs to help you diagnose the problem
and records the error in the error log.
Note: In messages and documentation, the term service processor refers to the
mini-baseboard management controller or the optional Remote Supervisor
Adapter II SlimLine.
The addition of an optional network interface card (NIC) provides a failover
capability to a redundant Ethernet connection. If a problem occurs with the
primary Ethernet connection, all Ethernet traffic that is associated with the
primary connection is automatically switched to the redundant NIC. If the
applicable device drivers are installed, this switching occurs without data loss
and without user intervention.

support
The server supports ServeRAID adapters to create redundant array of
independent disks (RAID) configurations. The server also has integrated RAID
level-0 and level-1 support in selected models. In addition, some hot-swap
models support RAID level-5 when a ServeRAID-MR10i SAS/SATA controller is
installed.
The server supports an optional Remote Supervisor Adapter II SlimLine, which
provides service-processor functions in addition to those that the mini-BMC
provides. When this adapter is used with the systems-management software that
comes with the server, you can manage the functions of the server locally and
remotely. The Remote Supervisor Adapter II SlimLine also provides system
monitoring, event recording, and dial-out alert capability.
See the documentation that comes with your systems-management software for
more information. To order an optional Remote Supervisor Adapter II SlimLine,
contact your Lenovo marketing representative or authorized reseller.
