Spirent Communication’s Holistic Testing Approach Prepares Enterprises for Dynamic, Terabit-Capacity Data Centers

Spirent Data Center Testing Solutions Deliver the Industry’s Only Unified Layer 2-7 Test Architecture for High Performance Virtualized, Eco-Friendly Networks

Las Vegas - Spirent Communications plc (LSE: SPT), a leader in networks, services and devices testing, announces the industry’s first holistic approach to validating the performance of tomorrow’s dynamic data centers. This approach offers a unified Layer 2-7 test architecture specifically designed to test the end-to-end performance of 10/40/100 Gigabit Ethernet fabrics, Fibre Channel over Ethernet (FCoE) convergence, virtualized server networking, cloud computing-based applications and security. Spirent was recently recognized by Frost & Sullivan as the leader in enterprise network test and measurement solutions for research and evaluation labs.

Tomorrow’s data centers are being designed around virtualized services and converged networks. These designs set new standards for network performance and scale, service availability, system security, application Quality of Experience (QoE) and power efficiency, which are only validated by a holistic test architecture. Trusted by the world’s leading network equipment manufactures, Spirent’s data center test architecture includes:

• Spirent TestCenter™: An award winning modular layer 2-7 performance test platform, Spirent TestCenter validates Quality of Service (QoS) and QoE of converged data center networks including FCoE with Converged Enhanced Ethernet (CEE) and Data Center Ethernet (DCE)
• Spirent TestCenter™ Virtual: A Best of Interop Finalist for 2009, Spirent TestCenter Virtual extends the capabilities of Spirent TestCenter to measure the true performance impact of virtualized servers, switches and appliances in tomorrow’s data center networks
• Spirent TestCenter Hypermetrics™: The award winning Spirent TestCenter Hypermetrics™, expands Spirent TestCenter performance to emulate the most realistic data center infrastructures with a multi-core, multi-dimensional HSE (10/40/100GbE) module that enables stateful, line-rate, layer 2-7 multi-play scalability at terabit capacities
• Spirent TestCenter™ Avalanche: The market leading Spirent TestCenter Avalanche is designed to validate network security, server load balancing and WAN acceleration while loading the data center application services including the Storage Sub System with NFS and CIFS
• Spirent TestCenter GreenPut™: An innovative approach, Spirent TestCenter GreenPut benchmarks the energy efficiency of deployed or soon-to-be deployed data center systems by measuring the throughput per watt of network elements, and calculating the power consumed under various traffic and session load
• Spirent TestCenter NoCode™: A fourth-generation visual programming environment, Spirent TestCenter NoCode, enables every test engineer to develop meaningful and repeatable test cases that more easily and more quickly finds defects with fewer test runs
• Spirent TestCenter™ OnDEMAND: By leveraging a team of testing experts working both on and off-site, Spirent TestCenter OnDEMAND validates all aspects of a data center to detect and mitigate performance, security, and scalability problems before the launch of new or advanced infrastructure and applications

“Market conditions are accelerating innovations around data center performance, scalability, security, and power efficiencies,” said Bill Burns, CEO at Spirent Communications. “Spirent’s holistic, unified test architecture enables today’s innovators to achieve their vision of building and deploying tomorrow’s dynamic data centers.”

Spirent’s holistic data center testing architecture will be on display at Interop 2009 at Spirent Booth #1051. The solutions will also be showcased at the Spirent Proof of Concept (SPoC) Labs and Collaboration Centers in Beijing, London and Sunnyvale.
