Abstract

Network Introduction

Figure 1-1 illustrates the networking of FusionStorage.

Figure 1-1 FusionStorage networking
  • Management network

    Used for managing and maintaining the system.

  • Service network (iSCSI)

    Allows communication between compute nodes and Volume Backup Service (VBS) through the iSCSI protocol.

  • Storage network

    Allows data communication between Object Storage Devices (OSDs) as well as between VBS and OSDs.

    The storage network can be deployed in two modes, depending on whether data communication between OSDs is isolated from that between VBS and OSDs:

    • Converged deployment: If data communication is not isolated, data communication between OSDs as well as between VBS and OSDs uses the same storage network.
    • Independent deployment: If data communication is isolated, the storage network is separated into the front-end storage network and the back-end storage network — the former is for communication between VBS and OSDs and the latter is for communication between OSDs.
  • BMC network

    Used to remotely manage hardware by connecting to the Mgmt ports of FusionStorage nodes.

Basic Concepts

Management node: a server that runs the FusionStorage Manager (FSM) process and provides operation and maintenance (O&M) functions, including alarm reporting, monitoring, logging, and configuration of FusionStorage.

NOTE:

Management nodes can be deployed on VMs, storage nodes, and external physical servers.

Management nodes can be deployed in active/standby (recommended) or standalone mode.

Storage node: a server that provides storage resources

Compute node: a server that runs application systems

Control Virtual Machine (CVM): When VMware vSphere or Microsoft Hyper-V is used as the virtualization environment, additional hosts or virtual machines (VMs) are needed to deploy VBS, because ESXi and Hyper-V hosts do not support VBS. Linux ESXi or Hyper-V VMs on which VBS is deployed are called CVMs.

Networking Schemes

If third-party servers are used as nodes, see Typical Networking Schemes.

If Huawei servers are used as nodes, see Typical Networking Schemes when Huawei Servers Are Used.

For details about replication network schemes, see the FusionStorage HyperMetro Feature Guide and FusionStorage HyperReplication Feature Guide.
