  2. 2. Copyright 2014 Juniper Networks, Inc.2 DATA CENTER ASSESSMENT What is it? A review of a customers existing networking environment in light of their business and technical goals. It enables customers to evaluate technology options and plan their networking/security journey whilst providing insight as to how a Juniper solution can potentially help meet their business goals. The need for an assessment is usually determined during a technical workshop near the start of the sales cycle. Juniper assessments are available for all product categories (DC, security, core, etc.) and are based on a common delivery methodology

  13. 13. Copyright 2014 Juniper Networks, Inc.13 EXAMPLE: A MAJOR INTERNATIONAL BANK Challenges to scale, host new services, or add resources because existing DCs were reaching limits of Power, Cooling and Space. Legacy Multi-tier design was complex to manage, causing outages, human errors, and bugs. Complexity/Heterogeneity of legacy infrastructures with too many DC sites, contributed to High Capex and Opex. Challenge Solution Results Redesign and overhaul of legacy switching infrastructure, in favor of a high-performance flat DC-Fabric deployment option. Homogeneous redesign of traffic-flows across sites / business-units / and functional segments. Leverage existing WAN MPLS network to provide DC Interconnect capabilities, in order to promote flexibility, scale, and business continuity capabilities. The solution proposed delivers 50+ differentiations and improvements in the previously defined network characteristics, enabling the Business Drivers. This includes: Increase 10G-enabled access rate from 1% to 100% 93% reduction in maximum East-West oversubscription Simplification of the main workflows by 70% 100% multi-homed and converged server connectivity Global, multi- site, large scale deployment with stringent availability and performance constraints
