The IP4700
Disk Modules
Each disk module (see Figure 1-9) consists of a Fibre Channel disk
drive in a carrier assembly. You can add or remove a disk module
while the IP4700 is powered up.

Disk Drives
The disk drives are 3.5-inch FC-AL drives that conform to the
following standards:
•
SFF-8067
•
Fibre Channel Arbitrated Loop (FC-AL)
•
FC-AL Private Loop Direct Attach (PLDA) profile
The disk module slots in the enclosure accommodate drives with
heights of either 1.0 inch or 1.6 inches. You can combine drives of
either height, and from different manufacturers, within the same
IP4700, subject to the restrictions imposed by the system software
running in the IP4700’s storage processors.
Drive Carrier
The disk-drive carrier is a plastic assembly that slides into the
enclosure slot guides and midplane connectors. It has a handle with a
latch and electrostatic discharge (ESD) clips, which connect to the
drive’s head-disk assembly. The latch holds the disk module in place
to ensure proper connection with the midplane.
