The 2.5-inch hard disk drive bays in front of the server can mount up to 16 hard disk drives with the 2.5 inch

The operation is executed on the created mirror volume with installed hard disk drive pairs such as slot 0 on
CPU/IO module 0/1, slot 1 on CPU/IO module 0/1, slot 2 on CPU/IO module 0/1. (The OS is installed on the
mirror volumes that consist of the hard disks in the slot 0.)

Empty slots in the 2.5-inch hard disk drive bay contain dummy trays. The dummy trays are inserted to improve
the cooling effect in the server. Always insert the dummy trays in the slots with no hard disks drive installed.
