Reliability, Availability, And Serviceability - Lenovo System x3630 M4 Installation And Service Manual

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.
• ServeRAID support 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.
• Systems-management capabilities 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.

Reliability, availability, and serviceability

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 correct problems.
The server has the following RAS features:
• Automatic error retry and recovery
• Automatic restart after a power failure
• Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy
• Cable-presence detection on most connectors
• Chipkill memory protection
• Dual redundant UEFI server firmware images
• Error codes and messages
• Error correcting code (ECC) L2 cache and system memory
• Cooling fans with speed-sensing capability
• Hot-swap hard disk drives (for servers that support such drives)
• Information and light path diagnostics LED panels
• Integrated management module (service processor)
• Memory mirroring
• Menu-driven setup, system configuration, and redundant array of independent disks (RAID) configuration
programs
• Parity checking or CRC checking on the serially-attached SCSI (SAS) bus and PCI buses
• Power management: compliance with Advanced Configuration and Power Interface (ACPI)
• Power-on self-test (POST)
• Predictive Failure Analysis (PFA) alerts on memory, SAS/SATA hard disk drives, fans, and power supplies
• Redundant Ethernet capabilities with failover support
• Redundant hot-swap power supplies
• Remote system problem-determination support
• Standby voltage for systems-management features and monitoring
• Startup (boot) from LAN through Preboot Execution Environment (PXE) boot agent utility or Dynamic Host
Configuration Protocol/Boot Protocol (DHCP/BOOTP)
• System auto-configuring from the configuration menu
• System error logging (POST and service processor)
• Systems-management monitoring through the Inter-Integrated Circuit (I
• Upgradeable POST, UEFI, diagnostics, service processor microcode, and read-only memory (ROM)
resident code, locally or over the LAN
• Vital product data (VPD) on microprocessors, system board, power supplies, and SAS (hot-swap-drive)
