  • Page 3: Introduction

    DATA CENTER BEST PRACTICES GUIDE NTRODUCTION The lack of good cable management impacts serviceability and availability of the SAN. A good cable management solution provides customers with the ability to dynamically scale and adapt to changes in their IT infrastructure while minimizing required service time. This document provides customers deploying high density solutions with general guidelines for proper cable management.

  • Page 4: Overview Of The Fc8-64 Fc Port Blade

    DATA CENTER BEST PRACTICES GUIDE Overview of the FC8-64 FC port blade The Brocade FC8-64 high density 64-port Fibre Channel blade (Figure 1) for the DCX Backbone family ® ® combines industry leading port density, performance, scalability, and reliability to maximize the benefits of SAN and server consolidation.
  • Page 5 DATA CENTER BEST PRACTICES GUIDE As an industry leader and innovator in high availability SAN solutions, Brocade developed a space efficient version of the standard Small Form Factor Pluggable (SFP+) media that enables high density port configurations as well as improved serviceability (Figure 2). These new “mini” SFPs (mSFP) retain all of the performance and functionality of the standard SFP+ and include individual port isolation for improved serviceability and availability.

  • Page 6: Planning

    DATA CENTER BEST PRACTICES GUIDE Figure 3. mSFP cable types LANNING As port density per a director and a rack increase, having an appropriate cable management plan is key especially during servicing or scaling out the fabric. The cable management plan should include current and future SAN design requirements.

  • Page 7: Using A Structured Approach

    DATA CENTER BEST PRACTICES GUIDE This inefficient approach also contributes to the over-heating of data centers—particularly within raised flooring and around the racks where cable clutter primarily occurs—requiring additional resources to cool the systems. Figure 4. Cable clutter Using a Structured Approach Cable management solutions designed specifically for Brocade SAN infrastructures (utilizing the Brocade DCX Backbone family) enable a reliable, flexible, and highly efficient cable infrastructure throughout the data center.

  • Page 9 DATA CENTER BEST PRACTICES GUIDE Extensive Cable Connection Mgmt Required: LC-LC single cables require more cable management. 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: •...

  • Page 10: Trusting The Standards

    DATA CENTER BEST PRACTICES GUIDE Trusting the Standards Industry cabling standards are designed to protect the end user. Whether these standards are in draft or ratified state, they provide a firm foundation for establishing a coherent infrastructure, and guidelines for maintaining high levels of cable performance. Cabling standards define cabling specifications looking out to the next several years, thus supporting future desires for higher speed transmissions.

    DATA CENTER BEST PRACTICES GUIDE (You can exclude Building and Room if there is only one instance of this entity in your environment.) Once the naming scheme is approved, you can start labeling the components. Be sure to create a reference document that will become part of the training for new data center administrators.
  • Page 12 DATA CENTER BEST PRACTICES GUIDE Cabling Installation (Front Side, Director Ports to Patch Panel): Start cabling from the top ports (e.g. port 31). Bundle the cables with Velcro in groups of eight to match the ASIC or trunk boundaries. This will facilitate servicing of the system through easy identification of the cable path.

This methodology provides for an attractive environment that facilitates cooler equipment, troubleshooting, and manageable growth or changes. Figure 7. Completed cabling Cabling Installation (Back Side, From Devices to Patch Panel): When connecting cables from outside devices to the backside of the patch panel, the cables should be routed through the patch panel’s backside punch-out holes.

  • Page 18: Summary

    DATA CENTER BEST PRACTICES GUIDE √ Use horizontal and vertical cable guides to route cables within and between racks. Use “cable spool” devices in cable managers to avoid kinks and sharp bends in the cable. Do not wrap patch cords around these spools like a hose on a hose reel.
