About ID pools

An ID pool is a collection of one or more ranges that you can be randomly generate or specify to provide large address spaces. By default, one virtual ID pool each of contiguous MAC addresses, WWNs, and serial numbers are created automatically when you initialize the appliance. The pools are composed of address and ID ranges. You can individually enable or disable a range, or delete any unused ranges. ID pool ranges do not conflict with physical IDs, provided the virtual ranges you create exclude the physical ID ranges.

Use an IPv4 or IPv6 address pool in a variety of applications:
  • Create an IPv4 or IPv6 subnet with one or more IPv4 or IPv6 address ranges you define. To assign static IP addresses to device bays, associate these IP ranges with an enclosure group, in which case IP addresses are assigned to the iLOs of server hardware populating these bays. IP ranges are also associated with interconnect bays, in which case IP addresses are assigned to the interconnect modules. Interconnects and iLOs share the same IP address pool.

  • Associate an IPv4 or IPv6 subnet with an Ethernet network. If this is an iSCSI network used as a deployment network, Image Streamer appliances can consume an IP address from one of the ranges for management of the appliance.

NOTE:
  • You cannot use IPv4 addresses in the reserved range of 172.30.254.0 to 172.30.254.255. HPE OneView uses this range on an internal private VLAN within the enclosure domain.
  • For Image Streamer, assign IPv4 addresses as deployment addresses (iSCSI initiators) for servers to boot from their OS volumes hosted on Image Streamer appliances.

  • IPv6 does not support loopback, multicast, and link-local addresses.

Supported ID pools

ID pool

Description

IPv4 addresses

Dot-decimal notation with four octets (decimals 0-255) separated by dots, for example, 192.168.1.1

IPv6 addresses

An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets, a group sometimes also called a hextet). The groups are separated by colons (:).

Virtual MAC addresses (vMAC)

  • 6 byte quantity represented as 12 hexadecimal characters, bytes separated by a colon (:)

  • Unicast address ranges only, multicast bit must not be set

Virtual World Wide Names (vWWN)

  • 8 byte quantity represented as 16 hexadecimal characters, bytes separated by a colon (:)

Virtual Serial Numbers (vSN)

  • 10 alphanumeric characters, uppercase
