DATA CENTER BEST PRACTICES GUIDE Extensive Cable Connection Mgmt Required: 1. LC-LC single cables require more cable management. 2. MPO trunk cables require less cable management. Selecting the appropriate cable management solution is dependent on your unique environment. The following flow chart is designed to assist you in determining the appropriate structured cable management solution for your environment based on key items to consider: • Is the SAN static or dynamic during its operational life cycle? • Are the devices near the directors or is there a central distribution panel? • Is there a trunked cable infrastructure already in place? • Is an individual fibre cable a requirement for fault isolation?

Selecting the appropriate cable management solution is dependent on your unique environment. The following flow
chart is designed to assist you in determining the appropriate structured cable management solution for your
environment based on key items to consider:
•
Is the SAN static or dynamic during its operational life cycle?
•
Are the devices near the directors or is there a central distribution panel?
•
Is there a trunked cable infrastructure already in place?
•
Is an individual fibre cable a requirement for fault isolation?
With proper cabling and patch panel labeling, both solutions (LC & MPO/MTP) provide flexibility in terms of
servicing and managing cables. With MPO/MTP, users have reduced cable density and since ports are in
groups of six, they also have a faster ability to identify a port for servicing if necessary but required expertise
in replacing individual connections within the trunk.
