Integrated Management Module (Imm); Uefi - IBM System x3850 X5 Implementation Manual

3.13.3 Integrated Management Module (IMM)

The System x3850 X5 includes an IMM that provides industry-standard Intelligent Platform
Management Interface (IPMI) 2.0-compliant systems management. You access the IMM
through software that is compatible with IPMI 2.0 (xCAT, for example). You implement the IMM
using industry-leading firmware from OSA and applications in conjunction with the Integrated
Management Module.
The IMM delivers advanced control and monitoring features to manage your IBM System
x3850 X5 server at virtually any time, from virtually anywhere. IMM enables easy console
redirection with text and graphics, and keyboard and mouse support (operating system must
support USB) over the system management LAN connections.
With video compression now built into the adapter hardware, it is designed to allow greater
panel sizes and refresh rates that are becoming standard in the marketplace. This feature
allows the user to display server activities from power-on to full operation remotely, with
remote user interaction at virtually any time.
IMM monitors the following components:
System voltages
System temperatures
Fan speed control
Fan tachometer monitor
Good Power signal monitor
System ID and planar version detection
System power and reset control
Non-maskable interrupt (NMI) detection (system interrupts)
SMI detection and generation (system interrupts)
Serial port text console redirection
System LED control (power, HDD, activity, alerts, and heartbeat)
IMM provides these features:
An embedded web server, which gives you remote control from any standard web
browser. No additional software is required on the remote administrator's workstation.
A command-line interface (CLI), which the administrator can use from a Telnet session.
Secure Sockets Layer (SSL) and Lightweight Directory Access Protocol (LDAP).
Built-in LAN and serial connectivity that support virtually any network infrastructure.
Multiple alerting functions to warn systems administrators of potential problems through
email, IPMI platform event traps (PETs), and Simple Network Management Protocol
(SNMP).

3.13.4 UEFI

The x3850 X5 uses an integrated Unified Extensible Firmware Interface (UEFI)
next-generation BIOS.
UEFI includes the following capabilities:
Human-readable event logs; no more beep codes
Complete setup solution by allowing adapter configuration function to be moved to UEFI
Complete out-of-band coverage by Advanced Settings Utility to simplify remote setup
