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
v Operator information panel
v Integrated management module (service processor)
v Memory mirroring
v Menu-driven setup, system configuration, and redundant array of independent
v Parity checking or CRC checking on the serially-attached SCSI (SAS) bus and
v Power management: compliance with Advanced Configuration and Power
v Power-on self-test (POST)

System x3620 M3 Type 7376: Installation and User's Guide
Note: You cannot mix 460-watt and 675-watt power supplies, or high-efficiency
and non-high-efficiency power supplies in the server.
Depending on the model, your IBM System x3620 M3 server implements
redundant array of independent disks (RAID) through software or hardware.
A ServeRAID adapter provides hardware RAID support to create configurations.
Depending on the server model, your server may come with a standard RAID
adapter that provides RAID levels 0, 1, 1E, or above. An optional RAID adapter
is available for purchase.
For server models that come with simple-swap hard disk drives, the servers
support software RAID levels 0 and 1 via the system firmware.
Note: When you enable software RAID on simple-swap models of the server,
you will no longer be able use the IBM Director, Dynamic System Analysis (DSA),
and ServerGuide tools to configure, diagnose, or update hard drives on
simple-swap models. However, you will still be able use these tools to configure
or diagnose other simple-swap server model features and components.
The server contains an integrated management module (IMM) which enables you
to manage the functions of the server locally and remotely. The addition of the
optional IBM Virtual Media Key provides remote presence and blue-screen
capture capability. The IMM also provides system monitoring, event recording,
and dial-out alert capability.
