CacheCade 119
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.
Manual Resizing of CacheCade Virtual Disks
In operating system management applications, a manual resizing of a
CacheCade virtual disk occurs due to the addition or removal of drives.
Reboot is not be necessary.
• Any number of SSDs can be added to a CacheCade virtual disk.
• There is no SAS and SATA mixing allowed within a CacheCade virtual
disk, so SATA SSDs cannot be added to a SAS CacheCade virtual disk and
vice versa.
• HDDs cannot be added to a CacheCade virtual disk.
NOTE: Capacity of drives added to a CacheCade volume must be equal to or
greater than the smallest contributing drive in the virtual disk. The manual resizing
of a CacheCade virtual disk cannot be initiated in the BIOS configuration utility. It
can only be initiated in the OpenManage storage management application.
