Dynamic Disk Pools
Dynamic Disk Pool (DDPs) is new feature that provides highly redundant and scalable RAID architecture,
also known as Controlled, Scalable, Decentralized Placement of Replicated Data (CRUSH). This
technology is used in place of traditional Virtual Disks groups and must be configured on the storage
array using the MD Storage Manager.
Before creating a Virtual Disks for vSphere client, you must either select an existing disk pool with free
capacity, select an existing Virtual Disks group with free capacity, or create a new Virtual Disks group
from unconfigured capacity or create a new disk pool from unconfigured capacity.
MD vCenter Plug-in supports creation of DDPs using the Virtual Disks tab in the selected storage array.
To create a DDP, select the Disk Pool option in the RAID Level drop-down list and select the number of
drives desired for the configuration.
NOTE: A minimum of 11 physical drives must be selected for the creation of a Dynamic Disk Pool.
