    Table 1 Zone parameters

    Parameter

    Description

    Name

    Indicates the name of the zone.

    Zone Type

    Indicates the type of the zone. Possible options are Global and NameNode.

    Sub-domain Name

    Indicates the subdomain name of the zone. This function must be used together with the DNS function in the subnet.

    DNS Policy

    Indicates the DNS policy of the zone. Possible options 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.

    • Number of 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.

    • Port throughput

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

    Associate File System ID

    Indicates the ID of the file system associated with the zone.

    DNS

    Indicates whether to enable the DNS service.

    IP Address Failover

    Indicates 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.
