Maximum number of network interfaces

Beginning with Data ONTAP 7.3, storage system can contain 256 to 1,024 network interfaces per system, depending on the storage system model, system memory, and whether they are in an HA pair.

The number of physical interfaces depends on the storage system model. Each storage system can support up to 16 interface groups.

You should run the sysconfig command and check the Memory size field displayed for the slot 0 system board of the storage system to determine the storage system memory.

The maximum number of network interfaces that each system can support is shown in the following table. The total number of interfaces can include physical, interface group, VLAN, vh, and loopback interfaces.

Storage system memory Maximum number of network interfaces
2 GB or less 128
2 GB or less in an HA pair 256
6 GB or less 256
6 GB or less in an HA pair 512
More than 6 GB 512
More than 6 GB in an HA pair 1,024
