    Table 1 Zone parameters

    Parameter

    Description

    Name

    Name of a zone.

    Zone Type

    Type of a zone.

    Home Subnet

    Subnet to which a zone belongs.

    Sub-domain Name

    Sub-domain name of a zone. This function must be used together with the DNS function in the subnet.

    Network Type

    Network type of ports in a zone. Only ports of this network type can be added to the zone.

    DNS Policy

    DNS policy of a zone. Possible values are as follows:

    • Round robin

      If clients access services using domain names, nodes are selected to process service requests of clients based on the sequence recorded in the cache.

    • Node connections

      If clients access services using domains names, nodes with the fewest connections are selected to process service requests of clients.

    • CPU usage

      If clients access services using domains names, nodes with the lowest CPU usage are selected to process service requests of clients.

    • Node throughput

      If clients access services using domains names, nodes with the lowest throughput are selected to process service requests of clients.

    DNS Service

    Whether the DNS service is enabled.

    IP Address Failover

    Whether to enable IP address failover. After this parameter is enabled, when a node is faulty, its IP address can be automatically allocated to another normal node. Therefore, clients can continue to access the storage system using this IP address. After failover, the new access node takes over services of the faulty node as extra service load, which may cause the access node to be overloaded.
