Lenovo THINKSERVER 3821 - Manual (Page 23)

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:
v UEFI-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.
v Integrated 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
v Remote 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.
v Preboot 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:
