In Dell UnityOS 4.2 and later, changes have been made to the System Settings > Storage Configuration section for all-flash systems. Drives is the only section under Storage Configuration in all-flash systems. As shown in Figure 14, this section displays all available drives within the system, along with other useful information. This figure displays many drives of varying sizes for demonstration purposes only. It is unlikely that a single all-flash system would have this many different drive types and sizes. The Drives page shows the available drives in the Drive Type column, with each entry shown by drive size. The Total column shows the number of drives of that size and type in the system currently.

The Unconfigured column has two sub-columns below it: Available and Traditional Spare. The Available column shows how many free drives are currently within the system. These drives can be used to create a dynamic pool. The Traditional Spare column shows how many drives are needed for traditional pool hot spares. In the example in Figure 14, one 15.36 TB SAS flash 4 drive needs to be reserved on the system as Traditional Spare, as denoted by the 1 in the 15.36 TB SAS flash 4 row within the Traditional Spare column.
The Configured column is also subdivided into two sub-columns: Dynamic Pool and Traditional Pool. These sub-columns show how many drives are currently configured within Dynamic Pools and traditional pools. In this example, a number of 15.36 TB SAS flash 4 drives have been placed into a traditional pool, and no other pools or drives have been configured on the system. Traditional pool information is not displayed in the Drives page if no traditional pools exist on the system.
For each non-zero number listed under the Unconfigured column, a clickable link is present. As shown in Figure 15, when the link for the 74 unconfigured 7.68 TB SAS flash 4 drives are selected in the Unconfigured column, a drive list is displayed. This list shows the drive locations for the free drives within the system, along with other information. This table can be used to easily determine the locations of the free drives within the system.
