NOTE:
LC connectors are small form-factor, fiber-optic connectors based on a
1.25-mm ceramic ferrule with a latching mechanism.
Other beneficial features of a typical SFP transceiver include a single power
supply, low power dissipation, and hot-swap capability. It is also important
that any transceiver you use meets the FC performance and reliability
specifications.
NOTE:
SFP transceiver modules must be purchased separately. You may also
purchase the SFP transceivers (GAL-9270CSFP4GA01) from your Galaxy
subsystem vendor/distributor.

Configuration
Rules
When you are cabling your subsystem, the following are some basic rules
that should be followed.
When selecting the number of hard drives that will be configured into a
logical configuration, the mechanical performance of the hard disks
should be considered.
