Overview

Overview

This chapter describes network planes and typical networking modes.

Network Planes

The overall network consists of the following planes:

  • Service plane: communicates with the user service network and provides S3 APIs externally.
  • Storage plane: enables communications among storage nodes of FusionStorage OBS.
  • Management plane: communicates with the user management network for management and maintenance of FusionStorage OBS.
  • BMC plane: connects to Mgmt ports of storage nodes to enable remote device management.
  • Control plane: maintains internal cluster information of FusionStorage OBS.

Typical Networking Modes

There are two networking modes: networking mode in which front and back ends use separate switches, and networking mode in which front and back ends share switches.

To ensure network security, you are advised to use the networking mode in which front and back ends use separate switches.

Figure 1-1 shows the networking mode in which front and back ends use separate switches.

Figure 1-1 Networking mode in which front and back ends use separate switches

Figure 1-2 shows the networking mode in which front and back ends share switches.

Figure 1-2 Networking mode in which front and back ends share switches

Based on the switch type, the networking can be classified into the following types:

  • Networking mode in which front and back ends use separate switches: front-end 25GE network + back-end 25GE network, front-end 10GE network + back-end 10GE network, and front-end GE network + back-end 10GE network
  • Networking mode in which front and back ends share switches: front-end 25GE network + back-end 25GE network, and front-end 10GE network + back-end 10GE network

The following cables are used in networking schemes:

  • Network cable
    • Connects NIC ports of storage nodes to the management switch.
    • Connects Mgmt ports of storage nodes or ETH management network ports of switches shared by the front and back ends to the BMC switch.
    • Connects SLOT ports of storage nodes to GE switches on a GE network.
  • Optical fiber
    • Connects the management switch, BMC switch, or switches shared by the front and back ends to the aggregation switches.
    • Connects SLOT ports of storage nodes to 10GE or 25GE switches on a 10GE or 25GE network.
  • High-speed cable
    • SFP+ high-speed cable: stacks 10GE optical ports between switches.
    • QSFP+ high-speed cable: stacks 40GE optical ports between switches.
    • QSFP28 high-speed cable: stacks 100GE optical ports between switches.
