Systems-management capabilities | Lenovo RD120 instruction

vSystems-management capabilities

The server supports an optional IBM Remote Supervisor Adapter II SlimLine. When you use this adapter, 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.

vTCP/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 microprocessors 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: As of the date of this document, the Linux operating system does not support TOE.

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:

vAutomatic error retry and recovery

vAutomatic restart after a power failure

vBackup basic input/output system (BIOS) switching under the control of the baseboard management controller

vBaseboard management controller (service processor)

vBuilt-in monitoring for fan, power, temperature, voltage, and power-supply redundancy

vCable-presence detection on most connectors

vAdvanced ECC memory protection

vError codes and messages

vError correcting code (ECC) L2 cache and system memory

vFully-buffered DIMMs (FBD) support

vHot-swap cooling fans with speed-sensing capability

vHot-swap hard disk drives

vHot-spare memory

vInformation and diagnostics LED panels

vMemory mirroring

vMenu-driven setup, system configuration, and redundant array of independent disks (RAID) configuration programs

vParity checking or CRC checking on the serially-attached SCSI (SAS) bus and PCI buses

vPower management: compliance with Advanced Configuration and Power Interface (ACPI)

vPower-on self-test (POST)

vRedundant Ethernet capabilities with failover support

vRedundant power supplies and redundant hot-swap fans (ac power supplies are hot-swap)

vRemind button to temporarily turn off the system-error LED

vRemote system problem-determination support

vStandby voltage for systems-management features and monitoring

vStartup (boot) from LAN through Preboot Execution Environment (PXE) boot agent utility or dynamic host configuration protocol/boot protocol (DHCP/BOOTP)
