6.1.5  Encrypted storage pools
Storwize V7000 supports two types of encryption: hardware encryption and software 
encryption.
Hardware encryption is implemented at an array level, whereas software encryption is 
implemented at a storage pool level. For more information about encryption and encrypted 
storage pools, see Chapter 12, “Encryption” on page 603.
6.2  Working with internal drives and arrays
An array is a type of MDisk that is made up of disk drives (or flash drive modules); these 
drives are members of the array. A Redundant Array of Independent Disks (RAID) is a 
method of configuring member drives to create high availability and high-performance groups. 
The system supports nondistributed (traditional) and distributed array configurations.
6.2.1  Working with drives
This section describes how to manage internal storage disk drives and configure them to be 
used in arrays.
Listing disk drives
The system provides an Internal Storage pane for managing all internal drives. To access the 
Internal Storage pane, navigate to Pools → Internal Storage, as shown in Figure 6-24 on 
page 208.
