## About Physical Storage Elements

Consider the following physical storage elements before you decide how to distribute data across the available physical storage:

- Arrays are sets of trays.
- Trays hold the disks, or disk drives, and support their operation. Each tray holds from 7 to 14 disks.
- Disks, or disk drives, are non-volatile, randomly addressable, rewriteable data storage devices.
- Initiators are the host bus adapters (HBAs) for the data hosts.
