Abstract
An information handling system includes a plurality of physical disks, a memory to store metadata for the physical disks, and a controller. The controller is configured to communicate with the physical disks and with the memory. The controller to receive a request to enable a redundant array of independent disks (RAID) mode on the physical disks, to allocate a portion of the memory to store the metadata while in the RAID mode, to store the metadata for the physical disks in each of the physical disks and in the portion of the memory, and to update and synchronize the metadata in response to a configuration change of the physical disks.
