03/06/2012 - Spirent Puts Performance and Scale of Juniper Networks QFabric Data Center Networking Solution to the Test


Any-to-Any Connectivity and Low-Latency Data Center Performance

Sunnyvale, California — (March 6, 2012) — Spirent Communications today announced that Network Test, an independent test lab, selected its solutions to complete the industry's first public 1,536 port 10G Ethernet test of QFabric™, Juniper Networks data center network fabric. Network Test worked with Spirent and Juniper Networks on an innovative methodology to test QFabric's performance at massive scale, under the most stressful yet realistic conditions. The results allow Juniper Networks to confidently address the scalability, performance and latency needs of increasingly large data centers. With a port density more than four times greater than any previous public test of its kind, this effort involved 1,536 10G Ethernet ports, measuring nanosecond latency at terabits per second.

Today's data centers are growing rapidly in scale, with increasing numbers of physical and virtual servers. This results in the need for high-density, high-speed fabric based networks with terabits of any-to-any port traffic. For these increasingly large scale data centers, it is imperative to understand how the network fabric will perform under stress, with latency-sensitive traffic running over it. This independent test of QFabric reflects real-world data center setups, with millions of application flows between any set of ports. It has important implications for cloud computing, storage and financial applications such as high-frequency trading and big data analytics.

Spirent enabled Juniper Networks to conduct the high-performance, low-latency testing necessary to assess and understand any-to-any connectivity, with the most stressful application traffic flows data center fabrics will encounter. Using the Spirent HyperMetrics dX test module, Juniper was able to scale traffic to over a trillion bytes and billion frames per second, measuring nanosecond latency on more than 2.3 million paths in full-mesh. This enables data centers deploying QFabric to fully characterize system performance and verify predictability when deployed in large mission-critical environments.

"As data center networks evolve and demand for fabrics rise this independent test demonstrates the performance scalability, and interoperability benefits a true fabric system can deliver to help customers solve the problems associated with growing data needs," said R. K. Anand, executive vice president and general manager, Data Center Business Unit, Juniper Networks. "Spirent's test equipment enabled the validation and demonstration of these benefits at large scale."

Spirent's test solutions play a key role in helping the data networking industry to address the performance and scale challenges facing data center operators. This test is just another example of why the industry continues to turn to Spirent for the most advanced and complete data center testing solutions available anywhere.

"Spirent and Network Test enabled Juniper Networks to showcase the performance of data center fabrics at massive scale, in enterprise and service provider networks," said Spirent Communications CEO Bill Burns. "Spirent has long been the leading proponent of test methodologies that validate data center performance at scale and with enhanced realism. This ground-breaking test of Juniper's QFabric system builds on that vision."
