DATA NETWORKING Data Center Challenges |

The heartbeat of any organization is in the data center. Employees, partners, and customers rely on data and resources in the Data Center to effectively create, collaborate, and interact. Over the last decade, the rise of Internet and Web-based technologies has made the data center more strategic than ever, improving productivity, enhancing business processes, and accelerating change. Data centers are the strategic focus of IT efforts to protect, optimize and grow the business. Data center managers face several challenges in fulfilling these goals. Most enterprise data centers grew rapidly to meet the explosive economic growth of the previous decade. Consequently, applications commonly stand alone in underutilized, isolated infrastructure silos. Each infrastructure silo is designed based on the inclination of the specific application being deployed, so that a typical data center supports a broad assortment of operating systems, computing platforms, and storage systems. The disparate infrastructures supporting different application "islands" are difficult to change or expand and expensive to manage, integrate, secure, and back up.
According to industry estimates, more than 70 percent of IT budgets are dedicated to sustaining existing application environments. Therefore, IT organizations must improve operational efficiency, optimize utilization of data center resources, and release funds for innovative new IT projects that help generate revenue. Data center managers need a resilient infrastructure that consistently protects diverse applications and services against disruptions and security attacks.
The ultimate goal is an agile infrastructure that can incorporate ongoing improvements in computer, storage, networking and application technologies, and empowers IT to support changing business processes. Using consolidation and virtualization technologies, Cisco Data Center solutions enable IT organizations to turn computing and storage resources from monolithic systems into a "service-centric" shared pool of resources consisting standardized components that can be dynamically aggregated, tiered, provisioned, and accessed through an intelligent network.

Elements of the Cisco Data Center Network
Architecture |
|
| |
Based on SONA, the Cisco Data Center Network Architecture comprises the following layers
- Networked Infrastructure Layer—Meets all the bandwidth, latency and protocol requirements for user to server, server to server and server to storage connectivity and communications.
- Interactive Services Layer—Provides the Infrastructure Enhancing Services which ensure the fast and secure alignment of resources with application requirements and Application Networking Services that optimize application integration and the delivery of applications to end users.
These services are integrated into the Cisco networking platforms that comprise the Networked Infrastructure Layer for enhanced, scalability, manageability and transparency.
This architecture supports the deployment of business applications and collaboration applications, whether deployed with traditional application architectures or emerging service oriented architectures.
