The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter contains the following sections:
You can define global VSANs in the domain group root, or a domain group below the root. Global VSANs are fabric-interconnect specific and can be created for either Fabric A or Fabric B. A global VSAN cannot be a common VSAN.
Resolution of global VSANs takes place prior to the deployment of global service profiles. If a global service profile references a global VSAN, and that VSAN does not exist, deployment of the global service profile fails due to insufficient resources. All global VSANs created in a Cisco UCS Central account must be resolved before deploying the global service profile.
A global VSAN is not deleted when you delete a global service profile that references it. Delete the global VSAN from the Cisco UCS Central account.
A global VSAN is visible to a Cisco UCS Manager account only if you deploy a global service profile that references the VSANs. Once a VSAN that is deployed with a global service profile becomes available in a Cisco UCS Manager account, you can include it in a local service profile and policy. You cannot turn a global VSAN into a local VSAN.
You can create a global VSAN with IDs from 1 to 4093, except for those in the following reserved ranges:
If you plan to use FC switch mode in a Cisco UCS domain, do not configure VSANs with an ID in the range from 3040 to 4078.
If you plan to use FC end-host mode in a Cisco UCS domain, do not configure VSANs with an ID in the range from 3840 to 4079.
Note | FCoE VLANs in the SAN cloud and VLANs in the LAN cloud must have different IDs. Using the same ID for an FCoE VLAN in a VSAN and for a VLAN results in a critical fault and traffic disruption for all vNICs and uplink ports using that VLAN. Ethernet traffic is dropped on any VLAN which has an ID that overlaps with an FCoE VLAN ID. |
WWN Pools
A WWNN (World Wide Node Name) pool is a WWN (World Wide Name) pool that contains only WW (World Wide) node names. If you include a pool of WWNNs in a service profile, the associated server is assigned a WWNN from that pool. You can view the WWN blocks and initiators in a WWNN pool by double-clicking the pool in the WWNN Pools tab.
A WWXN pool is a WWN pool that contains both WW node names and WW port names.

An IQN pool is a collection of iSCSI Qualified Names (IQNs) for use as initiator identifiers by iSCSI vNICs in a Cisco UCS domain. IQN pools created in Cisco UCS Central can be shared between Cisco UCS domains. IQN pool members are of the form prefix:suffix:number, where you can specify the prefix, suffix, and a block (range) of numbers. An IQN pool can contain more than one IQN block, with different number ranges and different suffixes, but sharing the same prefix

This template is a policy that defines how a vHBA (virtual Host Bus Adapter) on a server connects to the SAN. It is also referred to as a vHBA SAN connectivity template.
You need to include this policy in a service profile for it to take effect.
One or more of the following resources must already exist:

SAN connectivity policies determine the connections and the network communication resources between the server and the LAN on the network. These policies use pools to assign WWNs and WWPNs to servers and to identify the vHBAs that the servers use to communicate with the network.
Note | We do not recommend that you use static IDs in connectivity policies, because these policies are included in service profiles and service profile templates and can be used to configure multiple servers. |

The storage policy is a Cisco UCS Director policy that configures the connections between a server and SAN storage, including the World Wide Node Name (WWNN) assigned to the server and the virtual host bus adapters (vHBAs) used by the server. Depending upon the configuration you choose, this policy can be used to configure two or more vHBAs for the server. You can choose to create the vHBAs in this policy or use a SAN connectivity policy to determine the vHBA configuration.
You must include this policy in a service profile and that service profile must be associated with a server for it to take effect.

ID range qualification policies allow you to create policies and assign them to qualified domain groups and domain IP addresses. The ID range qualification policy is then visible to those domain groups and domain IP addresses. You can also create ID range qualification policies without assigning qualified domain groups or IP addresses. If you do not set qualifiers, the policy is available to all domain groups. ID resolution occurs hierarchically in the organization structure in the same manner as other global policies.
The ID Range Qualification Policy can be associated to:
