Addresses and Identifiers settings screen details

Addresses and Identifiers panel overview

On the Settings screen, the Addresses and Identifiers panel displays the number of currently available IPv4 addresses, MAC addresses, WWNs, and serial numbers. Click Edit in the panel to add an IPv4 subnet and address range, to autogenerate additional ID pool ranges, or to create a custom ID range.

For more information, see the following:

IPv4 Subnets and Address Ranges

These fields apply to Add and Edit operations.

Screen component	Description
Subnet ID	IP address representing the network ID of the subnet.
Subnet Mask	Bitmask that characterizes the subnet in which the range belongs. It is used in conjunction with the subnet ID to determine the network routing prefix.
Gateway	IP address of the gateway.
Domain	Domain name.
DNS	IP addresses of the DNS servers. Up to 3 DNS servers are supported.
Associated Networks	Link to the associated networks. The association is between the subnet and the VLAN ID.
Address Ranges	List of address ranges.
Available addresses	Number of available addresses for the subnet.
Name	Unique name for the address range.
First IP address	Starting address in the range.
Last IP address	Ending address in the range.
Enabled	Enable or disable the address range. By default, IPv4 address ranges are enabled.
Start	A valid IPv4 address for the start of the range.
End	A valid IPv4 address for the ending of the range.
Count	Total number of addresses in the range.
Allocated	Number of addresses in use.
Available	Number of available addresses remaining.
	Edit the subnet and address range.
	Remove the range of addresses and make them unavailable. You cannot remove a range or subnet that is associated with other resources or has addresses in use.
Buttons	See Standard UI buttons for information about how the standard UI buttons operate.

MAC Addresses

A media access control (MAC) address is a unique identifier assigned to network devices, often referred to as the hardware or physical address. The appliance generates MAC addresses in pools of 128 to 1,048,576 elements. By default, the appliance has 1,000,000 MAC addresses.

Screen component	Description
Enable Virtual (Edit screen)	By default, virtual addresses and identifiers are enabled so server profiles will be configured with virtual addresses and identifiers.
Type	`Generated` or `Custom` `Generated` is assigned during appliance setup. For `Custom`, you define the starting and ending addresses. There can be more than one of each type of pool; multiple autogenerated and custom pools.
Enabled	If you enable one or more virtual addresses or identifiers, a newly created server profile will be able to use them. When you disable virtual addresses, server profiles can only use physical addresses and identifiers. There must be at least one enabled pool range.
Start	Starting address in the pool. When you enable virtual addresses or identifiers, the predefined range is selected. The predefined range is large and randomly generated to prevent conflicts between profiles created in different realms. Supported MAC addresses are locally administered Unicast type addresses. Therefore, you have to set the second hex digit to an even number (2, 6, A, or E) to remain locally unique. Examples: `5E:1B:6C:80:00:00 - 5E:1B:6C:80:0F:FF` to create 4096 MAC addresses `5E:1B:6C:80:00:00 - 5E:1B:6C:80:FF:FF` to create 65K MAC addresses
End	Ending address in the pool The second hexadecimal number in a MAC address custom range must be 2, 6, A, or E to remain locally unique.
Count	Total number of addresses in the pool
Allocated	Number of addresses in use
Available	Number of available addresses remaining
Remove	Click X to remove the pool of addresses and make them unavailable. The X becomes visible when Count equals Remaining.
Add auto-generated button	Generates a pool of 1 million identifiers. Button is available only when editing.
Add custom range button	Generates a user-supplied pool of identifiers. Button is available only when editing.
Buttons	See Standard UI buttons for information about how buttons operate.

World Wide Names

A World Wide Name, (WWN) is a unique identifier assigned to storage devices connected to a network. WWNs are generated in pools of 128 to 1,048,576 elements. By default, the appliance has 1,000,000 WWNs.

Screen component	Description
Enable Virtual (Edit screen)	By default, virtual addresses and identifiers are enabled so server profiles will be configured with virtual addresses and identifiers.
Type	`Generated` or `Custom` `Generated` is assigned during appliance setup. For `Custom`, you define the starting and ending addresses. There can be more than one of each type of pool; multiple autogenerated and custom pools.
Enabled	If you enable one or more virtual addresses or identifiers, a newly created server profile will be able to use them. When you disable virtual addresses, server profiles can only use physical addresses and identifiers. There must be at least one enabled pool range.
Start	Starting address in the pool. When you enable virtual addresses or identifiers, the predefined range is selected. The predefined range is large and randomly generated to prevent conflicts between profiles created in different realms. IEEE Standard WWNs are used for the WWN pool, prepending `10:00` in front of a locally-administered unicast MAC address, such that the first four hex digits of the WWN are `1000`, and the sixth hex digit is 2, 6, A, or E. Examples: `10:00:5E:1B:6C:80:00:00 – 10:00:5E:1B:6C:80:0F:FF` is a valid range of 4096 WWNs `10:00:55:1B:6C:80:00:00 – 10:00:55:1B:6C:80:0F:FF` is an invalid range of 4096 WWNs
End	Ending address in the pool The second hexadecimal number in a WWN address custom range must be 2, 6, A, or E to remain locally unique.
Count	Total number of addresses in the pool
Allocated	Number of addresses in use
Available	Number of available addresses remaining
Remove	Click X to remove the pool of addresses and make them unavailable. The X becomes visible when Count equals Remaining.
Add auto-generated button	Generates a pool of 1 million identifiers. Button is available only when editing.
Add custom range button	Generates a user-supplied pool of identifiers. Button is available only when editing.
Buttons	See Standard UI buttons for information about how buttons operate.

Serial Numbers

Serial numbers are generated in pools of 128 to 46656 elements. By default, the appliance has 46,000 serial numbers.

Screen component	Description
Enable Virtual (Edit screen)	By default, virtual addresses and identifiers are enabled so server profiles will be configured with virtual addresses and identifiers.
Type	`Generated` or `Custom` `Generated` is assigned during appliance setup. Serial numbers are prefixed with `VCG`. For `Custom`, you define the starting and ending addresses. Serial numbers are prefixed with `VCU`. There can be more than one of each type of pool; multiple autogenerated and custom pools.
Enabled	If you enable one or more virtual addresses or identifiers, a newly created server profile will be able to use them. When you disable virtual addresses, server profiles can only use physical addresses and identifiers.
Start	Starting address in the pool. When you enable virtual addresses or identifiers, the predefined range is selected. The predefined range is large and randomly generated to prevent conflicts between profiles created in different realms. You can only assign a serial number with the prefix of `VCU` in order to prevent collisions with VCM and VCEM-defined ranges. Example: `VCU97JK000 – VCU97JK35R` is a range of 4096 serial numbers.
End	Ending identifier in the pool
Count	Total number of identifiers in the pool
Allocated	Number of identifiers in use
Available	Number of available identifiers remaining
Remove	Click X to remove that pool of identifiers and make them unavailable.
Add auto-generated button	Generates a pool of 46656 identifiers. Button is available only when editing.
Add custom range button	Generates a user-supplied pool of identifiers. Button is available only when editing.
Buttons	See Standard UI buttons for information about how buttons operate.
