System Design

System Design

The iBMC uses the Huawei proprietary Hi1710 chip, which is developed for board-level management. The Hi1710 chip consists of a single-core A9 CPU with a maximum frequency of 800 MHz, an 8051 single-chip microcomputer, and a co-processor with a frequency of 200 MHz. The Hi1710 chip supports remote KVM, IPMI, and PCIe for receiving and transmitting MCTP packets. It provides the local VGA, GE, and RMII ports, and a wide variety of board management ports and peripheral ports.

Figure 2-1 shows the iBMC system architecture.

Figure 2-1  System architecture

  • The KVM module implements remote keyboard and mouse control. When the KVM module receives video data from the operating system over the Peripheral Component Interconnect Express (PCIe) interface, it compresses the video data and sends the compressed data to a remote KVM client over the network. When the KVM module receives keyboard and mouse data from the remote KVM client, it transmits the data to the operating system by using a simulated USB keyboard and mouse device.
  • The iBMC receives the system running track information from the operating system over a PCIe interface and provides an interface for exporting the system running information.
  • The iBMC communicates with the operating system through a local PC (LPC) interface to implement IPMI management.
  • The iBMC provides GE interfaces to facilitate remote management over IPMI and HTTPS.
  • The iBMC uses sensors to monitor the server temperature and voltage. It also intelligently manages the fan modules and power supply units (PSUs) of the server.
  • The iBMC supports the network controller sideband interface (NC-SI) technology and VLAN function, allowing more flexible management networking.
    NOTE:
    Only the G560 V5 supports NC-SI.
