CHAPTER 25
Configuring WWN Pools
This chapter includes the following sections:
• WWN Pools, page 345
• Configuring WWNN Pools, page 346
• Configuring WWPN Pools, page 350
WWN Pools
A WWN pool is a collection of WWNs for use by the Fibre Channel vHBAs in a Cisco UCS domain. You
create separate pools for the following:
• WW node names assigned to the server
• WW port names assigned to the vHBA
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. To ensure the uniqueness of the Cisco UCS WWNNs and WWPNs in the SAN
fabric, we recommend that you use the following WWN prefix for all blocks in a pool:
20:00:00:25:B5:XX:XX:XX
Important
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.
