Dell PowerFlex 4.5.x Technical Overview

Volumes

You must add and configure volumes before enabling applications to access them.

The adding and mapping volume process is necessary, as part of the getting started process, before applications can access the volumes. In addition, you may create additional volumes and map them as part of the maintenance of the virtualization layer.

You can configure the caching option when creating the volumes, or you can change the Read RAM Cache feature later. If you want to enable the caching feature, ensure that the feature is also enabled in the backend of the system, for the corresponding storage pool and SDSs.

Define volume names according to the following rules:

• Contains less than 32 characters
• Contains only alphanumeric and punctuation characters
• Is unique within the object type

PowerFlex objects are assigned a unique ID that can be used to identify the object in CLI commands. You can retrieve the ID via a query, or via the property sheet for the object in PowerFlex Manager. It is highly recommended to give each volume a meaningful name associated with its operational role.
