Description

Name

A unique name for the network. Follow best practices for network naming conventions, if you have them.

NOTE:

If you are creating multiple tagged networks at the same time (creating networks in bulk), this name is automatically appended with an underscore (_) and the VLAN ID. For example, Dev_101.

Data type:

A maximum of 255 alphanumeric characters, spaces, and special characters with no leading spaces

Examples:
  • esx mgmt
  • vm601
  • SAN A
  • SAN_B
  • Dev_101
Type

(Create only)

Specifies the type of network you are creating.

Ethernet

An Ethernet network carries data traffic.

Fibre Channel

A Fibre Channel network carries storage traffic.

FCoE

An FCoE network carries storage traffic using a dedicated Ethernet VLAN.

VLAN

(Ethernet networks only)

(Create only)

The type of Ethernet network you are creating:

Tagged

A tagged Ethernet network contains multiple networks on a single uplink set which allows you to share uplinks with those networks.

When editing a tagged network, the VLAN ID is shown.

Untagged

An untagged Ethernet network is a single network with a dedicated set of uplink ports used to pass traffic without VLAN tags.

Tunnel

A tunnel network is a single network with a dedicated set of uplink ports used to pass a group of VLANs without changing the VLAN tags.

NOTE:

These networks can be used in internal networks or in uplink sets.

VLAN ID

(Tagged Ethernet or FCoE networks only)

(Create only)

The Virtual LAN identification number assigned to a network, entered as a single value

For tagged Ethernet networks, you can enter a combination of values or ranges to add networks in bulk, for example: 113, 114, 200-300.

When creating multiple tagged networks, the VLAN ID is appended to the Name. For example, if you entered Dev for the Name and 100–102 for the VLAN ID, the system creates networks Dev_100, Dev_101, and Dev_102.

NOTE:

When using a tunnel network for iSCSI boot, setting the VLAN ID is supported using the iSCSI function, however, when using the Ethernet function, HPE OneView 3.0 or greater will not allow you to set a VLAN ID. Therefore, if using a tunnel network for the Ethernet function, the network must be untagged or use the default VLAN ID on the top-of-rack (ToR) switch.

If you do not know which VLAN IDs have been assigned, contact your network administrator.

NOTE:

You cannot add FCoE networks in bulk.

Data type:

An integer greater than or equal to 1 and less than or equal to 4094

Associate with subnet ID

(Ethernet networks only)

For both tagged and untagged Ethernet networks, lists all subnets not currently associated with any VLAN. If the selected VLAN ID is already used by another network and there is an associated subnet, it lists only the configured subnet.

Subnet IDs cannot be assigned when a valid VLAN ID is not specified or when creating networks in bulk. When editing a network with an associated subnet, if the associated subnet is changed, validation will fail if any IP addresses are in use in the current subnet.

Purpose

(Ethernet networks only)

A description to attach to a network to help categorize the purpose of the network: General, Management, VM Migration, iSCSI, and Fault Tolerance.

The description does not affect the behavior of the network.

Fabric type

(Fibre Channel networks only)

(Create only)

The type of Fibre Channel connection the network uses to attach to external storage systems.

Fabric attach

Connects to external storage through SAN switches.

Direct attach

Connects directly to a 3PAR Storage system.

For more information about Fibre Channel connection types, see About Fibre Channel networks.

Associate with SAN

(Fabric-attach and FCoE)

The managed SAN to associate with this network. If selected, automatic zoning occurs as well as end-to-end connectivity verification. Automatic zoning connects a server profile on this network to its storage.

For more information about zoning, see About SAN zoning.

If you edit the network and change the association to a different SAN, you must confirm the change.

Preferred bandwidth

The preferred bandwidth, in Gb/s, for the network when the preferred bandwidth is configured on a port in a server profile. You can override this setting in a server profile.

This value cannot be greater than the maximum bandwidth. For Flex-10 or Flex-20 environments, up to four connections can share a single 10 or 20 Gb link.

For Fibre Channel networks, this value is not applicable. The connection speed will default to Auto.

Data type:

A number between 0.1 Gb/s and 20 Gb/s; a decimal point is not required.

Default value:

2.5

If you create multiple networks in one session, the default value is set to the value used for the last network you created. For example, if you specify 5 for the preferred bandwidth, the default value for this session is 5.

Examples:
  • 3.5
  • 5
Maximum bandwidth

The maximum bandwidth for a connection to the selected network, in Gb/s, when the selected network is configured on a port in a server profile. The maximum bandwidth defines the upper limit for the requested bandwidth allocation setting when the network is associated with a server profile.

This value cannot be less than the preferred bandwidth. The maximum bandwidth for a single physical port cannot exceed 10 Gb for 10-Gb adapters or 20 Gb for 20-Gb adapters.

For Fibre Channel networks, the maximum bandwidth is not applicable.

Data type:

A number between 0.1 Gb/s and 20 Gb/s; a decimal point is not required.

If you create multiple networks in the same session, the default value is set to the value used for the last network that you created. For example, if you set a value of 9.5 for the maximum bandwidth, the default for this session is 9.5.

Examples:
  • 8.5
  • 9
Smart link

(Ethernet networks only)

Smart Link causes the operating system to detect a failure and direct traffic to an alternative path.

NOTE:

Smart link must be selected for active/active configurations.

Private network

(Ethernet networks only)

This option provides additional network security by limiting traffic flow for the given network. When selected, all server ports connected to the network cannot communicate with each other within the logical interconnect. All server packets are sent through the logical interconnect and out the uplink ports.

Login redistribution

(Fibre Channel, fabric-attach networks only)

Used for login balancing when logins are not distributed evenly over the Fibre Channel links (for example, when an uplink that was down becomes available).

Auto

Login redistribution is initiated automatically when the link stability time expires.

Manual

Login redistribution must be initiated manually.

Link stability interval

(Fibre Channel, fabric-attach networks only)

This feature is enabled when Login redistribution is set to Auto.

The time in seconds that the module waits before reconnecting to a link that was previously offline (login redistribution). This interval prevents connection loss due to reconnecting to a link that is unstable (going online and offline repeatedly).

Data type:

A number from 1 to 1800, inclusive

HPE Virtual Connect FC Modules support a range of 5 to 1,800 seconds.

Default value:

30 seconds
