Disk Devices provide the underlying storage for SoftNAS and Storage Pools. Disk devices are attached to SoftNAS at the virtualization platform layer, often as virtual hard disks (e.g., VMDK in VMware, EBS volumes in EC2).
When a new disk device is attached, it usually starts out in a raw, unpartitioned state. Before it can be used, the disk device must be partitioned. The Disk Devices panel provides a list of disk devices, their status and the ability to manage the devices.
