About Trays and Disk Drives
Storage trays are identified by whether they contain a redundant array of independent disks (RAID) controller:
- A controller tray is a storage tray with hardware RAID management built into the controller.
- An expansion tray is a storage tray that has disks only and no controller. This type of tray is managed by a controller tray.
In the Sun StorEdge 6130 array, each tray has a minimum of 5 and a maximum of 14 disk drives, numbered 1 to 14, from left to right. With the maximum of 8 trays in a cabinet, you can have up to 112 drives. When a drive is installed, the drive and tray slot designations are set automatically.
You can use either 2 GB Fibre Channel (FC) or Serial Advanced Technology Attachment (SATA) disk drives. All drives in a tray must be of the same type.
Other characteristics of the Sun StorEdge 6130 disk drives are as follows:

Mixed drive sizes
|
Allowed but not recommended. If drives of different sizes are mixed in a storage tray, all the drives are treated as the smallest drive. For example, in a tray with a drive of 36 Gbytes and a drive of 146 Gbytes, only 36 Gbytes of the second drive is used. When the system is operating with mixed drive sizes, the hot-spare must be the size of the largest drive in the tray.
