Click the Properties button and then click on the Multipathing tab. Select the Enable multipathing on this server check box, and click OK. There is a short delay while XenCenter saves the new storage configuration.
Citrix XenServer and NetApp Storage Best Practices 29 3. Take the server back out of Maintenance mode by right clicking on the server in the Resources pane and click Exit Maintenance Mode. 3. Repeat the above steps for all servers in the pool that multipathing needs to be enabled on.
Citrix XenServer and NetApp Storage Best Practices 30 NIC Bonding NIC bonds can improve XenServer host resiliency by using two physical NICs as if they were one. If one NIC within the bond fails the host's network traffic will automatically be routed over the second NIC. NIC bonds work in an active/active mode, with traffic balanced between the bonded NICs. As such, XenServer host NICs should be bonded for NFS traffic to the NetApp device. It is recommended to use the following diagram as a guide to configure NIC bonding.

Citrix XenServer and NetApp Storage Best Practices 31 1. From XenCenter, click on the pool in the Resources pane (or server if this is a standalone server), and click on the Network tab. 2. Click on the Add Network… button. Select the Bonded Network radio button, and click Next>.
Citrix XenServer and NetApp Storage Best Practices 32 3. Add the NICs that need to be bonded from the Available NICs pane. Click Finish . 4. This will create a new network named Bond 2 + 3. 5. Select Bond 2 + 3, and click the Properties button to give the new network a more meaningful name and description.

Citrix XenServer and NetApp Storage Best Practices 34 8. Give the new interface a name, and choose the Network created in previous steps from the drop down. Click OK.
Citrix XenServer and NetApp Storage Best Practices 35 Shared Storage using StorageLink Gateway Use of the StorageLink Gateway for shared storage is the recommended approach for deployments of XenServer with NetApp. This type of storage repository is available with Citrix Essentials for XenServer, Enterprise Edition, and requires the installation of the StorageLink Gateway service on a Windows Server virtual machine or physical server. In addition to XenServer, StorageLink Gateway also supports Hyper-V hosts and provides storage interoperability between the two platforms. As mentioned before, the StorageLink Gateway only serves as a broker, and is not part of the data path between a XenServer host and the NetApp storage infrastructure.
