DATA CENTER BEST PRACTICES GUIDE INTRODUCTION 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. The demand for high density solutions are increasing as the need for the following grows: • Reduced footprint, energy efficiency (minimize cable impact on air flow) • Server consolidation and virtualization • Storage consolidation and virtualization The demands are resulting in: • Highly utilized racks minimizing the foot print • Increased cables per rack This guide describes: • Overview of the FC8-64 high density FC port blade • Challenges with unstructured high density port solutions • Structured high density cable management solutions based on LC and MPO/MTP® patch panels • Reference configuration for 256 port LC and 512 port MPO/MTP solutions • Part numbers for cables and patch panels and vendor contact information NOTE: For complete details on data center cabling practices, refer to the Best Practices Guide: Cabling the Data Center (PN: GA-BP-036-01). For additional FC8-64 and mSFP hardware details, refer to the Brocade DCX Backbone Hardware Reference Manual or the Brocade DCX-4S Backbone Hardware Reference Manual. Terminology Here are some common terms used in this best practices guide. Term Description mSFP Transceiver mSFP Cable LC MPO/MTP Patch Cord RU A narrower version of the standard 8Gb transceiver. A fiber cable with a narrower LC connector. Lucent Coupler Industry acronym for Multi-fiber Push-On connector; MTP is a trademarked name and is synonymous with MPO. Trunked cable with multiple fiber cables; commonly found in 12 or 24 fiber versions Rack Unit (4.4 centimeters/1.75 inches) NOTE: In this document, the terms MPO and MTP are used interchangeably and represent MPO and MTP connections.
