Automatic Reconfiguration of CacheCade Virtual Disks

There are two methods to reconfigure CacheCade virtual disks:

•Automatic reconfiguration of cachecade virtual disks

•Manual reconfiguration of cachecade virtual disks

Automatic Reconfiguration of CacheCade Virtual Disks

A CacheCade virtual disk that is made up of more than one SSD is automatically reconfigured upon a removal or failure of a member SSD. The virtual disk retains an Optimal state and adjusts its size to reflect the remaining number of member disks. If auto-rebuild is enabled on the controller, when a previously removed SSD is inserted back into the system or replaced with a new compatible SSD, the CacheCade automatically reconfigures and adjusts its size to reflect the addition of the member SSD. The number of SSDs to be removed from a CacheCade virtual disk cannot equal the total number of SSDs currently in the CacheCade virtual disk.

After the automatic reconfiguration and resizing of a CacheCade virtual disk, the new virtual disk size is displayed in both the BIOS configuration utility as well as in the OpenManage storage management application.

CAUTION: If a disk is removed from a CacheCade virtual disk, the associated slot for that disk is a hot slot for the CacheCade volume. Any compatible disk inserted into that slot is automatically added to the CacheCade virtual disk. Any pre- existing data on that drive is lost.

NOTE: Disks inserted into a CacheCade hot slot must be equal to or greater than the smallest contributing disk in the virtual disk.
