Lenovo 3823, 3821, 3822, 3719 manual Features and technologies, UEFI-compliant server firmware

Chapter 3. General information

This chapter provides general information that applies to all machine types supported by this publication.

Features and technologies

The TD200x server offers the following features and technologies:

vUEFI-compliant server firmware

The server firmware offers several features, including Unified Extensible Firmware Interface (UEFI) 2.1 compliance, enhanced RAS capabilities, and BIOS compatibility support. UEFI replaces the basic input/output system (BIOS) and defines a standard interface between the operating system, platform firmware, and external devices. UEFI-compliant servers are capable of starting UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.

Note: The server does not support DOS.

vIntegrated Management Module

The integrated management module (IMM) combines service processor functions, video controller, and remote presence function in a single chip. The IMM provides advanced service-processor control, monitoring, and alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. The IMM also provides a virtual presence capability for remote server management capabilities. The IMM provides remote server management through industry-standard interfaces:

–Intelligent Platform Management Interface (IPMI) version 2.0

–Simple Network Management Protocol (SNMP) version 3

–Common Information Model (CIM)

–Web browser

vRemote presence capability and blue-screen capture

The remote presence feature provides the following functions:

–Remotely viewing video with graphics resolutions up to 1600 x 1200 at 85 Hz, regardless of the system state

–Remotely accessing the server, using the keyboard and mouse from a remote client

–Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server

–Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the IMM restarts the server when the IMM detects an operating-system hang condition. A system administrator can use the blue-screen capture to assist in determining the cause of the hang condition.

vPreboot diagnostics programs

The preboot diagnostics programs are stored on the integrated USB memory. It collects and analyzes system information to aid in diagnosing server problems. The diagnostics programs collect the following information about the server:
