Lenovo 2595, 2593, 2594, 2579, 2577, 2592 manual Advanced system management features

–TMM (also known as BMC) and Intelligent Platform Management Interface (IPMI) 2.0

The system board platform management subsystem is based on the integrated TMM features. The TMM is a management chip that is integrated on the system board of your server. With the TMM, no matter what condition the server operating system is in and no matter if the server is on or off, as long as the server is connected to network and an ac power source, the interaction with the TMM-controlled servers can be achieved through system network. The user can obtain the server hardware health information and system event log (SEL), and is able to conduct the operations including turning on or off the server, restarting the server, locking the power switch on the front panel, and so on. This part of server management is independent of the operating system and is called out-of-band management.

The system board platform management subsystem consists of the integrated TMM, communication buses, sensors, the BIOS, and server management firmware. It is responsible for error reporting, system power control, thermal monitoring, system fan control, and other management features. The TMM provides system management and monitoring features based on the IPMI 2.0 specification. IPMI helps lower the overall costs of server management. You can find more information about IPMI 2.0 from the Web site of Intel. The TMM also supports some non-IPMI features, such as the Dynamic Host Configuration Protocol (DHCP) and the Platform Environment Control Interface (PECI), to provide more system management functions.

–Hot-swap feature

Your server supports hot-swap hard disk drives, hot-swap system fans, and hot-swap redundant power supplies. With the hot-swap feature, you can install, remove, or replace a hot-swap device without turning off the server.

–Preboot Execution Environment (PXE)

The Intel PXE technology enables you to boot your computers, load an operating system, or deploy executable images from a remote server by using a network interface. The operation can be done independently of local data storage devices (such as hard disk drives) or operating systems.

–Redundant Array of Independent Disks (RAID)

Your server supports advanced SATA/SAS hardware RAID if your server has a required RAID card installed. For detailed information, see “Configuring RAID” on page 64.

–Status light-emitting diodes (LEDs) and diagnostic LEDs

For more information about the LEDs for your server, refer to the related topics in “Locations” on page 14.

–Software programs

For more information about the software programs, see “Software” on page 12.

–Wake on LAN

When the Wake on LAN feature is enabled on a computer that is connected to a LAN, a network administrator can remotely turn on or wake up the computer from a management console using remote network management software. Besides, many other functions, such as data transfer and software updates, can be performed remotely without remote attendance and can be done after normal working hours and on weekends to save time and increase productivity.

•Advanced system management features

The TMM firmware supports the following advanced system management features.

Note: The advanced system management features are only available when the TMM detects the presence of a ThinkServer Management Module Premium (TMM Premium), which also is known as integrated keyboard, video, and mouse (iKVM) key. The TMM Premium is a remote management module. You can purchase a TMM Premium from Lenovo and install it on the TMM Premium connector (also known
