Introduction

This document lists which Lenovo System x, NeXtScale, Flex System, and BladeCenter servers support the Integrated Management Module II (IMM2) service processor and the older Integrated Management Module (IMM) service processor.

The IMM and IMM2 consolidate service processor functionality previously provided by the combination of the Baseboard Management Controller (BMC) and the Remote Supervisor Adapter II in System x and BladeCenter products.

Integrated Management Module II

Integrated Management Module II (IMM2) is the second-generation management module integrated on System x servers. IMM2 offers three levels of functionality: Basic, Standard, and Advanced.

Upgrading to Standard or Advanced will be performed using a software license key using Lenovo Features on Demand (FoD).

IMM2 Basic has the following features:

  • Industry-standard interfaces and protocols
  • Intelligent Platform Management Interface (IPMI) Version 2.0
  • Common Information Model (CIM)
  • Advanced Predictive Failure Analysis (PFA) support
  • Continuous health monitoring
  • Choice of a dedicated or shared Ethernet connection
  • Supports secure SSH text console access with optional encryption capabilities using AES cyphers
  • Domain Name System (DNS) server support
  • Dynamic Host Configuration Protocol (DHCP) support
  • Embedded Dynamic System Analysis (DSA)
  • LAN over USB for in-band communications to the IMM
  • Serial over LAN
  • Server console serial redirection
  • Remote firmware updating
  • Remote configuration through Advanced Settings Utility (ASU)

Note: IMM2 Basic does not include web browser or remote presence capabilities.

IMM2 Standard (as standard in some servers or as enabled using the Features on Demand software license key in other servers) has the following features:

  • Secure web server user interface
  • Remote power control
  • Access to server vital product data (VPD)
  • Advanced Predictive Failure Analysis (PFA) support
  • Power Management
  • Automatic notification and alerts
  • Continuous health monitoring and control
  • Choice of a dedicated or shared Ethernet connection
  • Domain Name System (DNS) server support
  • Dynamic Host Configuration Protocol (DHCP) support
  • E-mail alerts
  • Syslog logging support
  • Embedded Dynamic System Analysis (DSA)
  • Enhanced user authority levels
  • LAN over USB for in-band communications to the IMM
  • Event logs that are time stamped, saved on the IMM, and that can be attached to e-mail alerts
  • Support for Industry-standard interfaces and protocols: IPMI V2.0, CIM, and SNMP
  • OS watchdogs
  • Serial over LAN
  • Server console serial redirection
  • User authentication using a secure connection to a Lightweight Directory Access Protocol (LDAP) server

IMM2 Advanced (as enabled using the Features on Demand software license key) has the following features:

  • Remote presence, including remote control of server via a Java or ActiveX client
  • Supports up to four concurrent remote users
  • Operating system failure screen capture and display through the web interface
  • Video recorder and playback function
  • Virtual media allowing the attachment of a diskette drive, CD/DVD drive, USB flash drive, or disk image to a server. For servers with an SD Media adapter installed, you can configure volumes on those SD Cards for use by the IMM.

Note: For servers where only IMM2 Basic is installed (for example, x3100 M4, x3250 M4, nx360 M4), the use of IMM2 Advanced requires IMM2 Standard also be purchased and enabled.

The following table lists the IMM2 upgrades.

Note: The IMM2 Advanced upgrade requires the IMM2 Standard upgrade.

Integrated Management Module

In older System x servers, the Integrated Management Module (IMM) consolidates the service processor functionality, Super I/O, video controller, and remote presence capabilities in a single chip on the server system board. The IMM consolidates service processor functionality previously provided in the BMC and the Remote Supervisor Adapter II in System x and BladeCenter products.

Lenovo offers two levels of IMM, Standard and Premium. If the server has IMM Standard functionality, it can be upgraded to IMM Premium by purchasing and installing a Virtual Media Key (either part number 46C7526 or 46C7527, depending on the server) on the server system board. This key is a physical component (Figure 1). However, no new firmware is required. IMM Premium provides Remote Presence and Virtual Media capabilities. Figure 1 shows where the Virtual Media Key is installed in one of the supported servers (x3620 M3).

BladeCenter server support

The BladeCenter Management Module (MM) and Advanced Management Module (AMM) are the central points of management for the BladeCenter chassis. As such, when the AMM is not responsive, the ability to perform normal management on the chassis is significantly compromised. The AMM is Version 2 of the MM. The main differences are that the AMM is USB based (instead of PS/2) and also has a feature to save service data. The service data collects most of the useful information that is required to support the AMM.

Each BladeCenter chassis, with the exception of the BladeCenter S, supports a redundant pair of management modules. The two management modules used in a chassis must be identical.

The MM/AMM is used to monitor, manage, configure, report logs, and update firmware from BladeCenter chassis blades and I/O modules. Although the IMM is now included in some blade servers, the AMM remains the management module for systems-management functions for BladeCenter and blade servers. There is no external network access to the IMM on blade servers. The AMM must be used for remote management of blade servers. The IMM replaces the functionality of the BMC and the Concurrent Keyboard, Video, and Mouse (cKVM) option card in past blade server products:

  • The Advanced Management Module for BladeCenter S, BladeCenter E, BladeCenter H, and BladeCenter HT is part # 25R5778.
  • The Advanced Management Module for BladeCenter T is part # 32R0835.
  • The original MMs have been withdrawn but were only supported in BladeCenter E (BC-E, part # 48P7055) and BladeCenter T (BC-T, part # 90P3741).

All BladeCenter chassis models with the original MM installed can be upgraded to an AMM. In fact, most current servers require that the chassis have AMMs installed.

The following table lists the service processors that are standard and optional in each BladeCenter chassis.

Table 6. Management models standard in each BladeCenter chassis

BladeCenter chassis Management Module (MM) Advanced Management Module (AMM)
BladeCenter E, machine types 8667, 1881, 7967, 8760 Some models have the MM standard. Some models have the AMM standard.
BladeCenter T, machine types 8267, 8720, 8730 Some models have the MM standard. Some models have the AMM standard.
BladeCenter H, machine types 8852,1886, 7989 No Standard
BladeCenter HT, machine types 8740, 8750 No Standard
BladeCenter S, machine types 8886,1948, 7779 No Standard

The following table lists the service processors that are standard for each of the currently available BladeCenter servers. For older servers, see the Lenovo Press document, Service Processors Supported in System x Servers, available from:
