    Chapter 1: About this Document

    Overview

    Introduction EMC's commitment to consistently maintain and improve quality is led by the Total Customer Experience (TCE) program, which is driven by Six Sigma methodologies. As a result, EMC has built Customer Integration Labs in its Global Solutions Centers to reflect real-world deployments in which TCE use cases are developed and executed. These use cases provide EMC with an insight into the challenges currently facing its customers. This document summarizes a series of best practices that were discovered, validated, or otherwise encountered during the validation of the EMC Infrastructure for Virtual Desktops Enabled by EMC Celerra Unified Storage (NFS), VMware vSphere 4, and Citrix XenDesktop 4 solution.
