describes the HMM specifications.
The Integrated Baseboard Management Controller (iBMC) and the Hyper Management
Module (HMM) implement management and monitoring of the X6800. The iBMC on
each node implements node management through the Intelligent Platform Management
Interface (IPMI), KVM, or virtual DVD-ROM drive. The HMM implements chassis
management, which includes management of fan modules, PSUs, and chassis assets.
The HMM and iBMC implement converged management over the LAN switch (LSM)
chip in the chassis. The LSM provides an external GE port. You can log in to the HMM
and iBMC over the external GE port to manage the chassis and server nodes.
The HMM works with the fan switch boards to implements fan management. The fan
switch board provides five independent pulse-width modulation (PWM) control signals
to control the fan speed and ten tachometer (TACH) signals to detect the fan speed.
Based on the ambient temperature and temperature of the temperature-sensitive
components on server blades, HMM uses Huawei speed adjustment algorithms to

Specifications
Supports integration with any standard management system
through the following interfaces:
l IPMI V2.0
l CLI
Allows the faulty MM to be replaced without interrupting
system operating and restores the working mode of the MM in
short time.
Provides intelligent asset management to increase efficiency.
Uses the power capping technology to increase deployment
density and dynamic energy saving technology to lower
operating costs.
Integrates the out-of-band management of all server nodes in
the chassis, reduces the cabling of the management network,
and shortens maintenance time.
