Storage Shelf front panel components
The 2U12 Storage Shelf contains 12 disk drive storage bays that are populated with 8 TB 7200 rpm SAS hard disk drives. The available backup storage capacity of the storage shelf equals 65 TiB. One of the disk drives is reserved as a hot spare. All disk drives are accessible from the front panel of the storage shelf after you remove the storage shelf bezel.
The following figure shows the front panel disk drive slot assignments within the 2U12 Storage Shelf.
The storage shelf uses the drive that is located in slot 11 as a hot-spare drive.
Each storage shelf hard drive is housed in a disk drive carrier. Each disk drive carrier uses a locking mechanism that secures the disk drive within the storage shelf.
The following table describes the disk drive carrier LEDs. Note that the combination of both LEDs provides the status.
