Planning Networks

Planning Networks

Properly plan the network settings of a storage system to ensure that application servers can safely and efficiently access shared files.

NOTE:

If you want to enable IP address failover for improving reliability of links before configuring basic storage services, you must reserve at least two Ethernet, VLAN, or bond ports for IP address failover and ensure that no IP addresses are configured for the ports. When a port fails, services can be smoothly switched to the other port. For details about how to configure and manage IP address failover, see the IP address failover deployment guide specific to your product model and version.

Planning Ethernet Ports

Ethernet ports are ports physically visible on a device. They are the bases of virtual local area networks (VLANs), bond ports, and logical ports.

Planning Bond Ports

Port bonding provides more bandwidth and link redundancy. After Ethernet ports are bonded, MTU changes to the default value and you must set the link aggregation mode for the ports. On Huawei switches, you must set the ports to work in static LACP mode.

NOTE:

Port bonding has the following restrictions:

  • Only Ethernet ports with the same rate (GE or 10GE) on a same controller can be bonded. A maximum of eight Ethernet ports can be bonded as a bond port.
  • Ports on SmartIO interface modules cannot be bonded if the modules are in cluster or FC mode or run FCoE services in FCoE/iSCSI mode.
  • The MTU of bonded SmartIO ports must be the same as that of the hosts.
  • Read-only users are unable to bond Ethernet ports.
  • Each port can be added to only one bond port.
  • A bond member port cannot be added to a port group.
  • Although ports are bonded, each host still transmits data through a single port and the total bandwidth can be increased only when there are multiple hosts. Determine whether to bond ports based on site requirements.
  • The link aggregation modes vary with switch manufacturers. If a non-Huawei switch is used, contact technical support of the switch manufacturer for specific link aggregation configurations.

Planning VLANs

VLANs logically divide physical Ethernet port resources into multiple broadcast domains. In a VLAN, when service data is being sent or received, a VLAN ID is configured for the data, so that the networks and services of VLANs are isolated, further ensuring service data security and reliability.

VLANs are created based on Ethernet ports or bond ports. One physical port can belong to multiple VLANs. A bond port instead of a single member port can be used to create a VLAN.

Planning Logical Ports

Logical ports, used for NAS service operation, are created based on Ethernet ports, bond ports, or VLAN ports.

  • A physical port can be configured with logical ports on the same or different network segments.
  • Different physical ports on a controller can be configured with logical ports on the same or different network segments.
  • Logical ports can be created on Ethernet ports, bond ports, or VLAN ports only if these ports are not configured with any IP addresses.
  • An Ethernet port, bond port, or VLAN port configured with logical ports can only be used for either the block or file storage service.
  • You must specify a home port for logical ports. If the home port fails, services will fail over to a functional port.
  • You must activate a logical port before using it.
