ProLiant DL rack mount server models support only physical serial numbers, MAC addresses, and WWN addresses.

Description

Serial number/UUID

Determines whether the server profiles created from the server profile template uses virtual or physical serial number and UUIDs.

  • Virtual serial numbers and UUIDs are generated by the appliance and enable flexibility.

    The benefit of virtual serial numbers is that when you use a virtual serial in a server profile template and assign the template to a server bay, any server that is inserted in that server bay uses the same serial number.

  • Physical serial numbers are reported by the server BIOS and associate a serial number to the server.

MAC addresses

Determines whether the server profiles created from the server profile template uses virtual or physical MAC addresses.

  • Virtual MAC addresses are generated by the appliance and are used by the servers.

    The benefit of specifying virtual MAC addresses in a server profile template is that when you assign the template to a server, any server that is inserted in that server bay uses the same MAC addresses.

    Thus, a server replacement does not affect the data center interconnects because they do not detect any change in MAC address.

  • Physical MAC addresses are reported by the server BIOS and associate a MAC address to the server.

    Physical MAC addresses are burned in on the server NICs. If you replace a server, the physical MAC changes and you must update the data center interconnects.

WWN addresses

Determines whether the server profiles created from the server profile template uses physical or virtual World Wide Name (WWN) addresses (for Fibre Channel networks).

  • WWN addresses are generated by the appliance and are used by the servers.

    The benefit of specifying virtual WWN addresses in a server profile is that when you assign the template to a server, any server that is inserted in that server bay uses the same WWN addresses.

    Thus, a server replacement does not affect the data center interconnects because they do not detect any change in WWN address.

  • Physical WWN addresses are reported by the server BIOS and associate a WWN address to the server.

    Physical WWN addresses are burned in on the server NICs. If you replace a server, the physical WWN changes and you must update the data center interconnects.

Hide unused FlexNICs

This setting provides the ability to hide unused FlexNICs from the operating system.

If Hide Unused FlexNICs is selected (enabled), FlexNICs that do not map to any server profile connections are not presented to the operating system. For example, if you have a full complement of eight FlexNICs defined in your server profile but map only four, your operating system will see only the four mapped FlexNICs instead of eight.

If Hide Unused FlexNICs is not selected (disabled), eight FlexNICs are enumerated in the operating system as network interfaces for each Flex-10 or FlexFabric adapter.

Configuring Fibre Channel connections on a FlexFabric adapter can enumerate two storage interfaces, reducing the number of network interfaces to six.

FlexNICs are hidden in pairs, starting with the fourth pair. For example, if the fourth FlexNIC on either physical port corresponds to a profile connection, all eight physical functions are enumerated. If a profile connection corresponds to the second FlexNIC on either physical port, but no connection corresponds to the third or fourth FlexNIC on either physical port, only the first and second physical functions are enumerated in the operating system.

By default, Hide Unused FlexNICs is enabled.
