UCS Storage policies Explained
I- vHBA Template
This template is a policy that defines how a vHBA on a server connects to the SAN. It is also referred to as a vHBA SAN connectivity template.
You must include this policy in a service profile for it to take effect.
Creating a vHBA Template
This policy requires that one or more of the following resources already exist in the system:
- Named VSAN
- WWNN pool or WWPN pool
- SAN pin group
- Statistics threshold policy
|tep 1||In the Navigation pane, click SAN.|
|Step 2||Expand SAN > Policies.|
|Step 3||Expand the node for the organization where you want to create the policy.If the system does not include multitenancy, expand the root node.|
|Step 4||Right-click the vHBA Templates node and choose Create vHBA Template.|
|Step 5||In the Create vHBA Template dialog box, complete the asked fields|
Binding a vHBA to a vHBA Template:
You can bind a vHBA associated with a service profile to a vHBA template. When you bind the vHBA to a vHBA template, Cisco UCS Manager configures the vHBA with the values defined in the vHBA template. If the existing vHBA configuration does not match the vHBA template, Cisco UCS Manager reconfigures the vHBA. You can only change the configuration of a bound vHBA through the associated vHBA template. You cannot bind a vHBA to a vHBA template if the service profile that includes the vHBA is already bound to a service profile template.
II- SAN Connectivity Policy:
SAN connectivity policies determine the connections and the network communication resources between the server and the SAN 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||These policies are included in service profiles and service profile templates, and can be used to configure multiple servers. So, using static IDs in connectivity policies is not recommended.|
Creating or Editing a SAN Connectivity Policy:
|Step 1||In the Actions bar, type Create SAN Connectivity Policy and press Enter.|
|Step 2||In the SAN Connectivity Policy dialog box, click Basic and choose the Organization in which you want to create the policy.|
|Step 3||Enter the Name and optional Description.The name is case sensitive.|
|Step 4||In Identifiers, choose the WWNN pool.For more information|
|Step 5||In vHBAs, create one or more vHBAs and select the properties. You can manually create the vHBA, use a vHBA template, or create a redundancy template pair.|
|Step 6||Click Create.|
III- Fibre Channel Adapter Policies
These policies govern the host-side behavior of the adapter, including how the adapter handles traffic. For example, you can use these policies to change default settings for the following:
- Interrupt handling
- Performance enhancement
- RSS hash
- Failover in an cluster configuration with two fabric interconnects
reating or Editing a Fibre Channel Adapter Policy
|Step 1||In the Actions bar, type Create Fibre Channel Adapter Policy and press Enter.|
|Step 2||In the Fibre Channel Adapter Policy dialog box, click Basic and choose the Organization in which you want to create this policy.|
|Step 3||Enter a Name and optional DescriptionThe policy name is case sensitive.|
|Step 4||In Resources, complete the fields as necessary.|
|Step 5||In Settings, complete the fields as necessary.|
|Step 6||Click Create.|
IV- Storage Connection Policy
The storage connection policy contains a collection of target storage ports on storage array that you use to configure fibre channel zoning.
From Cisco UCS Central you can create a storage connection policy in an organization.
