The E9000 server management module MM910 implements central management of the hardware devices in the chassis. Each E9000 chassis is configured with two MM910s in active/standby mode.

The MM910s support active/standby switchovers and hot swap. It supports the following protocols:

  • Intelligent Platform Management Interface 2.0 (IPMI 2.0)
  • Simple Network Management Protocol Version 3 (SNMPv3), SNMPv1 trap, SNMPv2c trap, and SNMPv3 trap
  • Secure Sockets Layer (SSL)
  • Secure Shell (SSH)
  • Secure File Transfer Protocol (SFTP)
  • Hypertext Transfer Protocol Secure (HTTPS)
  • Network Time Protocol (NTP)
  • Domain Name Service (DNS)
  • Lightweight Directory Access Protocol (LDAP)
  • Simple Mail Transfer Protocol (SMTP)
  • For security purposes, the SNMPv1, SNMPv2c, and Telnet protocols are disabled by default.
  • The MM910 only supports Linux NTP servers.

The MM910 supports the following features:

  • Centralized management of the components in the chassis
    • Monitors the status of the components in the chassis.
    • Receives alarms sent from each component and reports them to the upper-layer network management system.
    • Supports remote startup, shutdown, reset, and power-on and power-off operations for compute nodes.
    • Records and provides logs.
    • Manages users, including the MM910 administrators and baseboard management controller (BMC) users of compute nodes.
  • Stateless computing

    The MM910 provides stateless computing to simplify configuration and maintenance of the compute nodes in an E9000 chassis. Stateless computing allows the compute node hardware configuration to be extracted and saved as a profile. The profile can be configured offline, migrated, remotely deployed in batches, exported, or imported.

  • Local KVM

    The local keyboard, video, and mouse (KVM) feature allows users to:

    • Access the MM910 command-line interface (CLI) and the OS of a compute node.
    • Mount the DVD drive on the active MM910 to a compute node.
    • Connect a compute node to a switch module using serial over LAN (SOL).
  • KVM over IP

    The KVM over IP function allows users to use the local KVM to access and manage a compute node in real time.

    Table 2-1 lists the browser and Java Runtime Environment (JRE) versions that support the KVM over IP function on a client.

  • Virtual media

    The virtual media feature allows users to:

    • Mount the local DVD drive or FDD to the OS of a compute node.
    • Mount the *.iso or *.img file from the local PC to the OS of a compute node by using the virtual DVD drive or virtual FDD.
  • SOL

    The SOL sets up a serial data transmission channel between a remote client and the serial port of a compute node or a switch or pass-through module. Maintenance engineers can manage the compute node or switch module remotely from the client.

  • Unified upgrade

    The MM910 supports self-upgrade and upgrade of components in the chassis. Table 2-2 lists the components and firmware that can be upgraded through the MM910.

Table 2-2 Supported components and firmware for upgrades





  • Firmware
  • Complex programmable logical device (CPLD)
  • Online help

The active and standby MM910s can be upgraded at the same time.

Compute node

  • CPLD
  • Baseboard management controller (BMC)
  • Basic input/output system (BIOS)

Compute nodes of the same model can be upgraded at the same time.

Switch module

  • CPLD
  • BMC
  • Base
  • Fabric

Switch modules of the same model can be upgraded at the same time.

The switch module has the following planes:

  • Base: LOM GE switching plane
  • Fabric: 10GE switching plane

Fan module


Fans of the same model must be upgraded one by one.

Chassis intelligent display

  • Firmware
  • Configuration data

The chassis intelligent display can be upgraded only using the MM910 CLI.


The power supply units (PSUs) cannot be upgraded through the MM910.

  • Offline configuration of switch modules

    The MM910 stores the switch module configuration files (profiles). When a switch module starts, it automatically loads the profile from the MM910. This feature simplifies switch module deployment.

  • Configuration inheritance of switch modules

    After a switch module is replaced, the OS of the new switch module loads the profile of the original switch module from the MM910. If the MM910 does not have the profile, the OS of the new switch module loads the default profile.

  • Power capping for the entire chassis.

    A power cap value can be set on the MM910 for the entire chassis based on the actual power consumption requirements.
