2: Storage Enclosures
Disk Drives
18
Each storage enclosure can contain up to 14 low-profile Fibre Channel disk drives.
Controller enclosures can be cabled to as many as seven expansion enclosures for a total
capacity of 112 disks in one storage system. Each disk is mounted in a sled for ease of
installation and removal. These drive sleds have a lever and latch mechanism that allows
you to cam the drive in and out of the enclosure. Figure 2-3 shows the drive sled and
drive bay numbering scheme for the TP9300.
Each drive has two status LEDs (see Figure 2-3) as follows:
•
Drive active LED: This LED illuminates green when a drive is in the drive bay, and
it blinks when the drive is active.
•
Drive fault LED: This LED illuminates amber when there is a problem with the
drive.
