Citrix Hypervisor

Changing SR Properties

The Properties dialog box allows you to modify the details of your SR and manage them effectively by organizing the resources using folders, tags, and custom fields. It also allows you to configure alerts when the storage throughput exceeds specific limits.

To view the details of a storage repository, select a server or pool in the Resources pane and then click the Storage tab. This tab displays information about the local and shared storage repositories. This information includes the name, description, storage type, usage, and size of the SR. Select an SR from the list and click Properties.


The General tab allows you to change the name and description of the SR, and manage its folder and tags:

  • To change the name of the SR, enter a new name in the Name box.
  • To change its description, enter new text in the Description box.
  • To place the SR in a folder or to move it to a different folder, click Change in the Folder box and select a folder. For more information, see Using folders.
  • To tag and untag the SR and to create and delete tags, see Using tags.

Custom fields

Custom fields allow you to define or modify any additional information about the SR. This tab helps you to search and effectively organize your storage repositories. For more information, see Using custom fields.


The Alerts tab allows you to configure alerts when the total read and write storage throughput activity on a Physical Block Device (PBD) exceeds the specified limit. Check Generate storage throughput alerts and set the storage throughput and time threshold that triggers the alert.


Physical Block Devices (PBD) represent the interface between a specific Citrix Hypervisor host and an attached SR. When the total read/write SR throughput activity on a PBD exceeds the threshold you have specified, alerts are generated on the host connected to the PBD. Unlike other host alerts, this alert must be configured on the relevant SR.

Read Caching

On the Read Caching tab, you can choose to enable or disable read caching.

Read caching improves performance on NFS, EXT3/EXT4, or SMB SRs that host multiple VMs cloned from the same source. You might want to disable read caching in the following cases:

  • You have no file-based SRs
  • You do not have any cloned VMs
  • It is not providing any performance benefits

For more information, see Storage read caching.
