Identity Pools in OpenManage Enterprise
24 Advanced Server Configuration in Dell EMC OpenManage Enterprise 3.0
Identity range addresses specified in one Identity Pool cannot overlap identity range addresses in another
Identity Pool (or even in the same Identity Pool), irrespective of protocol.
This rule applies based on address type. For example, MAC addresses. MAC address ranges are
specified for Ethernet identities, iSCSI Initiator identities, and FCoE identities. A MAC address range in
one Identity Pool (regardless of the protocol) cannot overlap with any other MAC address range, either in
the same Identity Pool or in a different Identity Pool.
When any identities in a sub-pool of an Identity Pool are Reserved or Assigned, the only change allowed
to those sub-pools is to increase their size. The starting address cannot be changed and the count cannot
be reduced.
Each Identity Pool definition should include a sub-pool for each type of virtual identity expected to be enabled
in the Templates with which the Identity Pool will be associated.
Most Identity Pools will need an Ethernet sub-pool, for use as virtual MAC addresses for network
communications. Each NIC port usually requires a virtual MAC address. If partitioning is enabled, each
partition could require a virtual MAC address (unless Ethernet is disabled on the partition).
If an Identity Pool will be associated with templates where iSCSI could be enabled, either for connections
or for booting, then an iSCSI identity range for MAC addresses should be specified. If iSCSI may be
enabled for booting, then an IQN prefix and an IP range should also be specified (unless it is known for
certain that every template to be used for deployment will specify that iSCSI Initiator settings be obtained
from a DHCP server).
If an Identity Pool will be associated with templates where FCoE could be enabled, then an FCoE identity
range should be specified.
If an Identity Pool will be associated with templates that may have Fibre Channel host bus adapter, then a
range should be specified for Fibre Channel (FC) identities.
Each installation should determine the number of identity pools, sub-pools per Identity Pool, and sub-pool
sizes that best fit their needs.
