A WWN pool is a collection of WWNs for use by the Fibre Channel vHBAs in
a
Cisco UCS
instance. You create separate pools for the following:
WW node names assigned to the server
WW port names assigned to the vHBA
Important:
A WWN pool can include only WWNNs or WWPNs in the ranges from
20:00:00:00:00:00:00:00 to 20:FF:FF:FF:FF:FF:FF:FF or from
50:00:00:00:00:00:00:00 to 5F:FF:FF:FF:FF:FF:FF:FF. All other WWN ranges are
reserved.
If you use WWN pools in
service profiles,
you do not have to manually configure the WWNs that will be used by the server
associated with the
service profile.
In a system that implements multi-tenancy, you can use a WWN pool to control
the WWNs used by each organization.
You assign WWNs to pools in blocks. For each block or individual WWN,
you can assign a boot target.
WWNN Pools
A WWNN pool is a WWN pool that contains only WW node names. If you
include a pool of WWNNs in a
service profile, the associated server is assigned a WWNN from that pool.
WWPN Pools
A WWPN pool is a WWN pool that contains only WW port names. If you
include a pool of WWPNs in a
service profile, the port on each vHBA of the associated server is assigned
a WWPN from that pool.
