Selecting VC-assigned MAC address ranges
When using VC-assigned MAC addresses, you can choose between using an HP pre-defined MAC address
range or using a user-defined MAC address range.
• HP pre-defined MAC address range (recommended). These pre-defined ranges are reserved and are
not the factory default on any hardware. There are 64 ranges of 1024 unique addresses to choose
from. Be sure to use each range only once within a data center.
1024 unique addresses might not be enough for a large configuration (multiple enclosures with many
Flex-10 NICs). If you plan a domain of this type, determine the number of MAC addresses you are likely
to use, and then select an option that provides the domain with sufficient MAC addresses.
• User-defined MAC address range. To avoid potential conflict with other hardware MAC addresses in
the environment, consider using a subrange of MAC addresses reserved by the IEEE for
locally-administered MAC addresses. Ensure that the range does not conflict with any Ethernet device
already deployed within the enterprise.
IMPORTANT: If you plan to use Insight Control Server Deployment for RedHat Linux installation
and also plan to use User- or HP-defined MAC addresses, you must import the enclosure and
assign profiles before running Insight Control Server Deployment.
NOTE: After any server profiles are deployed using a selected MAC address range, that range
cannot be changed until all server profiles are deleted.
