Map Extensible Storage location to a Storage Volume (for integration with Storage Volume Snapshots)


Creation Date: May 28, 2011
Revision Date: September 18, 2012
Product: DS-System

Summary

This feature is enabled by the DS-System's "UseSnapshot" Parameter (See "DS-System Advanced Configuration".).

DS-System can integrate with some storage volumes (e.g. NAS) in order to use their native snapshot capability when performing the following (read-only) tasks:

When a snapshot is used, the DS-System is able to free the backup set lock on the corresponding backup set almost immediately. This can significantly improve performance in high availability environments, since the backup set can continue to receive new backup data and the activity using the snapshot can be configured to process that data on a separate network.

This article assumes you have a functioning NAS with defined storage volumes and that it is visible to your DS-System on the network.

Note: DS-System using NetApp NAS has been tested with in standalone configuration. Clustered mode (C-mode) NetApp NAS has not been tested. Although support may be possible, it has not been verified.

Mapping a DS-System Extensible Storage Location to a Storage Volume

For background information, refer to the section "Extensible Storage".

You must map each storage location in the Extensible Storage Locations list to a unique Storage Volume defined on the NAS. The snapshot will only work if all Extensible Storage Locations can successfully generate a snapshot when requested by DS-System.

1. Setup menu > Storage > Extensible Storage.

F1 Help: See "Extensible Storage Locations".

2. To edit an existing Storage Location, highlight it from the list and click Edit.

3. The New / Edit Storage Location screen appears.

F1 Help: See "New / Edit Storage Location".

4. Enter / Update the required information about the Storage Location. In the Storage Volume field, you can select from the list (if you already have Storage Volumes defined). When you select an item from this list, you are mapping this Extensible Storage Location to that NAS Storage Volume.

5. Click [...] beside the Storage Volume field to define or edit the list of Storage Volumes. The Storage Volumes screen appears.This is a list that you create to map each NAS Storage Volume to a path (mount point or UNC path) where the DS-System can read/write/delete data on that Storage Volume.

F1 Help: See "Storage Volumes".

6. To add a new Storage Volume, click Add.

To edit a Storage Volume, highlight one from the list and click Edit. The New / Edit Storage Volume screen appears.

F1 Help: See "New / Edit Storage Volume".

7. Click OK to save the mapping for this Storage Volume. The Storage Volumes screen returns. Once you have finished defining all the NAS Storage Volumes you require, click "Close" to exit this screen.
