occurs with one of the power supplies, Active Energy Manager can act to<br />

minimize the load somewhat so that the server can function with the remaining<br />

power supply.<br />

Note: You cannot mix high-efficiency <strong>and</strong> non-high-efficiency power supplies in<br />

the server.<br />

v RAID support<br />

Depending on the model, your IBM <strong>System</strong> <strong>x3630</strong> <strong>M3</strong> server implements<br />

redundant array of independent disks (RAID) through software or hardware.<br />

A ServeRAID adapter provides hardware RAID support to create configurations.<br />

Depending on the server model, your server may come with a st<strong>and</strong>ard RAID<br />

adapter that provides RAID levels 0, 1, 1E, or above. An optional RAID adapter<br />

is available for purchase.<br />

v <strong>System</strong>s-management capabilities<br />

The server contains an integrated management module (IMM) which enables you<br />

to manage the functions of the server locally <strong>and</strong> remotely. The addition of the<br />

optional IBM Virtual Media Key provides remote presence <strong>and</strong> blue-screen<br />

capture capability. The IMM also provides system monitoring, event recording,<br />

<strong>and</strong> dial-out alert capability.<br />

Reliability, availability, <strong>and</strong> serviceability features<br />

Three important computer design features are reliability, availability, <strong>and</strong><br />

serviceability (RAS). The RAS features help to ensure the integrity of the data that<br />

is stored in the server, the availability of the server when you need it, <strong>and</strong> the ease<br />

with which you can diagnose <strong>and</strong> repair problems.<br />

The server has the following RAS features:<br />

v Automatic error retry <strong>and</strong> recovery<br />

v Automatic restart after a power failure<br />

v Built-in monitoring for fan, power, temperature, voltage, <strong>and</strong> power-supply<br />

redundancy<br />

v Cable-presence detection on most connectors<br />

v Chipkill memory protection<br />

v Dual redundant UEFI server firmware images<br />

v Error codes <strong>and</strong> messages<br />

v Error correcting code (ECC) L2 cache <strong>and</strong> system memory<br />

v Cooling fans with speed-sensing capability<br />

v Hot-swap hard disk drives<br />

v Information <strong>and</strong> light path diagnostics LED panels<br />

v Integrated management module (service processor)<br />

v Memory mirroring<br />

v Menu-driven setup, system configuration, <strong>and</strong> redundant array of independent<br />

disks (RAID) configuration programs<br />

v Parity checking or CRC checking on the serially-attached SCSI (SAS) bus <strong>and</strong><br />

PCI buses<br />

v Power management: compliance with Advanced Configuration <strong>and</strong> Power<br />

Interface (ACPI)<br />

v Power-on self-test (POST)<br />

v Predictive Failure Analysis (PFA) alerts on memory, SAS/SATA hard disk drives,<br />

fans, <strong>and</strong> power supplies<br />

v Redundant Ethernet capabilities with failover support<br />

v Redundant hot-swap power supplies<br />

v Remote system problem-determination support<br />

v St<strong>and</strong>by voltage for systems-management features <strong>and</strong> monitoring<br />
