Ixia shows full 400G networking at 12.8Tbyte/s
Ixia, part of Keysight Technologies, has demonstrated the maximum performance capabilities of new 400GE, PAM4-based silicon from Marvell for the first time at 12.8Tbyte/s.

The demonstration used Ixia's AresOne-400 Gigabit Ethernet (GE) test system and the Marvell Prestera CX 8580 Ethernet switch at the Open Compute Project (OCP) Global Summit this week in the US.

"The 400GE ecosystem is rapidly maturing," said Alan Weckel, founding analyst for 650 Group. "The availability of PAM4-based silicon is critical to achieving the performance – throughput, latency and jitter – that 12.8Tbps speeds require. This demonstration illustrates the maturity of the PAM-4 based silicon market over the past 18 months."

The Prestera CX 8580 switch, a 12.8Tbps, 256x 50G device, is part of a new family of switches from Marvell that works with its Storage Aware Flow Engine (SAFE) technology and a reduction in network layers leveraging its high radix switch core technology known as FASTER.

"We are excited to showcase our newly announced Marvell Prestera CX 8500 family with a powerful RFC compliant 32x400G demonstration. This feature-rich family leverages the testing capability of Ixia's AresONE test equipment to test the scale, 12.8Tbps, and wide range of packet encapsulations that are supported by the switch pipeline," said Guy Azrad, vice president of engineering, Networking Business Unit and general manager at Marvell Israel.  "This collaboration testifies to both organizations' ability to support the design, deployment and testing of the next generation, high-speed network infrastructure that will be needed to keep pace with ever-growing data demands."

"This demonstration highlights the capabilities of the AresONE-400GE test system and the Marvell Prestera CX 8580 switch to support real-world applications in the data center," said Sunil Kalidindi, vice president of product management at Keysight's Ixia Solutions Group. "We are proud to showcase the world's first and only full-box 12.8Tbps 400GE test with Marvell and demonstrate the maturity of our solutions as 400GE rapidly becomes mainstream."

At OCP, Ixia is also demonstrating an 8-port AresOne-400GE system running a 12.8Tbps using 4 separate units chained together to perform as a single 32-port system. The Ixia AresONE-400GE test system enables network equipment providers
