Creating a New SR

Oct 06, 2014

To create a new storage repository, click New Storage on the Toolbar.

Alternatively, do one of the following:

  • On the Storage tab for the selected pool or server, click New SR.
  • On the Storage menu, click New SR.

You select the physical storage type on the first page of the New Storage Repository wizard and then follow the steps in the wizard as it takes you through the configuration process for that storage type. The set of available settings in the wizard depends on the storage system vendor/model you select on the first page. Click the links below to find out more about creating different types of SR.

SR creation steps

The New Storage Repository wizard takes you through process of creating a new SR:

  1. On the Type page, you select the type of underlying storage:
    Option Description Read more
    NFS VHD In NFS VHD SRs, VM images are stored as thin-provisioned VHD format files on a shared NFS target. Existing NFS servers that support NFS V3 over TCP/IP can be used immediately as a storage repository for virtual disks. NFS SRs can be shared, allowing any VMs with their virtual disks in an NFS VHD storage repository to migrated between servers in the same resource pool. NFS VHD Storage
    Software iSCSI Software iSCSI SRs use a shared Logical Volume Manager (LVM) on a SAN attached LUN over iSCSI. iSCSI is supported using the open-iSCSI software iSCSI initiator or by using a supported iSCSI Host Bus Adapter (HBA). Software iSCSI Storage
    Hardware HBA Hardware HBA SRs connect to a Fibre Channel (FC), Fibre Channel over Ethernet (FCoE) or shared Serial Attached SCSI (SAS) LUNs via an HBA. You need to carry out the configuration required to expose the LUN before running the New Storage Repository wizard: the wizard will automatically probe for available LUNs and display a list of all the LUNs found. Hardware HBA Storage
    StorageLink Technology This option allows you to configure a StorageLink SR that provides native access to automated fabric/initiator and array configuration features in NetApp/IBM N Series or Dell EqualLogic PS Series arrays. The exact features available for a given StorageLink SR depend on the capabilities of the array.
    Important: StorageLink technology has been removed from XenServer version 6.5 and higher. Applications, code, or usage that depend on StorageLink technology will not function in XenServer version 6.5 and higher. For information about migrating existing virtual disks (VDIs) from a StorageLink technology SR to an iSCSI or Fibre Channel SR, see CTX141433.

    Window File Sharing (CIFS) CIFS ISO SRs handle CD images stored as files in ISO format available as a Windows (CIFS) share. This type of SR can be useful for creating shared ISO libraries, for example, VM installation images. ISO Storage
    NFS ISO NFS ISO SRs handle CD images stored as files in ISO format available as an NFS share. This type of SR can be useful for creating shared ISO libraries, for example, VM installation images. ISO Storage
  2. On the Name page, enter the name of the new SR. By default, a description of the SR will be generated automatically by the wizard, including 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.
  3. On the Location pages, you enter the location of the underlying storage array and set configuration settings. The options available on this and subsequent wizard pages will depend on the type of storage you selected on the first page of the wizard.
  4. Click Finish to create the new SR and close the wizard.
