Software FCoE Storage

Software FCoE provides a standard framework that hardware vendors can plug in their FCoE offload-capable NIC into. By using this framework, they get the same benefits of a hardware-based FCoE. This feature eliminates the need for using expensive HBAs. Software FCoE can be used with Open vSwitch and Linux bridge as the network back end.

Before creating a software FCoE storage, complete the configuration required to expose a LUN to the host. This process includes configuring the FCoE fabric and allocating LUNs to your SAN’s public world wide name (PWWN). After you complete this configuration, the available LUN is mounted to the host’s CNA as a SCSI device. You can then use the SCSI device to access the LUN as if it were a locally attached SCSI device. For information about configuring the physical switch and the array to support FCoE, see the documentation provided by the vendor. For detailed information about Software FCoE, see the Storage

Note:

  • When you configure the FCoE fabric, do not use VLAN 0. The Citrix Hypervisor host cannot find traffic that is on VLAN 0.
  • Software FCoE can be used when using Open vSwitch and Linux bridge as the network back end.

To create a Software FCoE SR

  1. To open the New Storage Repository wizard, do one of the following actions:
    • On the toolbar, click New Storage.
    • On the Storage tab for the selected pool or server, click New SR.
    • On the Storage menu, click New SR.
    • In the Resources pane, select a server or pool then right-click and click New SR on the shortcut menu.
  2. Select Software FCoE as the Storage type and click Next.
  3. Enter a name for the new SR. By default, the wizard generates a description of the SR. This description includes a summary of the configuration options you select as you progress through the wizard. To enter your own description, clear the Auto-generate description check box and type in the Description box. Click Next to continue to the Location page.
  4. XenCenter probes for available LUNs and displays a list of LUNs currently exposed to the host. This page also displays detailed information about the LUN such as, the size, serial, ID, NIC. Choose the LUN (s) that you want to allocate to the SR and click Next.

    Note: If the host cannot find any LUNs, an error message is displayed. Verify your hardware configuration and retry to continue with the SR creation process.

  5. Review the summary and click Finish to complete the SR creation process.
