30 Product Overview
Link Controller Card (VA 7110/7400/7410 Only)
The link controller card (LCC) functions as a fiber optic transceiver for the disk
enclosure. It allows up to six disk enclosures to be connected to the controller
enclosure. Each LCC includes a Fibre Channel address switch, used to set the
Fibre Channel loop address of the card. Each disk enclosure must have a
unique address and both LCCs in a disk enclosure must be set to the same
address. For cabling connections and switch settings, see Figure 8 for the
VA 7110, Figure 9 for the VA 7400, and Figure 10 for the VA 7410.
The LCC also monitors the operation of the disk enclosure and provides status
information to the array controller. This includes what disks are present and
their status, power supply status, and notification if the enclosure operating
temperature has exceeded its limits.
Disk Drives
Up to 15 disks can be installed in each disk enclosure. The controller enclosure
and the disk enclosure both use the same disk drives. See "Disk Drives" on
page 26.
Image Disks
The image disks can be located in either the controller enclosure or the disk
enclosure. See "Image Disks" on page 27.
Disk Drive Filler Panels
The controller enclosure and the disk enclosure both use the same disk drive
filler panels. See "Disk Drive Filler Panels" on page 28.
