Keysight Sets New Benchmark for Silicon Validation of AI Ethernet Switching at 51.2T
31 Enero 2024 - 10:00AM
Business Wire
- Validates the performance of next-generation data center
switches used in advanced AI and accelerated computing
environments
- First comprehensive test to process 51.2 Tbps of traffic across
64 x 800GE links while measuring loss, latency, and jitter
- Showcases the ability of independent vendors to maintain
connection of all 64 links on a high-speed Ethernet switch running
at line rate, a building block for AI cloud architectures
Keysight Technologies, Inc. (NYSE: KEYS) has achieved a new
milestone in validating the accelerated infrastructure necessary to
power the next-generation AI-driven cloud data center with
Keysight's AresONE-M 800GE test platform and the Marvell® Teralynx®
10 Ethernet switch chip.
AI networks require high performance, unprecedented scale, and
low-latency switching fabric to ensure seamless handling of massive
volumes of data and real-time decision-making that advanced AI
workloads demand. Keysight collaborated with Marvell Technology,
Inc. to address the unique testing needs of network equipment
manufacturers, silicon chipset vendors, and data center operators
as they equip, build, and manage high-speed 800GE and 1.6T
networks. Implementing an effective validation strategy helps
mitigate the risk of costly product re-designs, recalls, or
negatively impacting customer loyalty by assuring solutions will
perform as designed and promised in real-world environments.
The milestone testbed was comprised of Keysight’s AresONE-M
800GE, the industry’s most comprehensive multi-speed Ethernet
performance test platform and traffic generator, and the Marvell
Teralynx 10 Ethernet programmable switch device, which offers
industry-leading low latency, supporting up to 51.2 Tbps throughput
with comprehensive analytics.
Highlights from the validation include:
- High throughput and high speed – The Keysight AresONE-M
800GE generated 51.2 Tbps of traffic, sending it successfully
through the Teralynx 10 switch to test its limits. The test
validated an 800GE interface speed based on 112G SerDes, which
facilitates faster data transfer between devices and extended reach
in data center interconnects or telecommunications networks that
run data-intensive AI applications.
- Unprecedented scalability – Eight AresONE-M 8-port
chassis were chained together, providing an industry first 64 x
800GE link configuration to achieve a high scale test bed running
at 800GE line rate.
- Low latency – Low latency is critical for achieving the
shortest job completion time for AI training and other highly
distributed applications. These AI workloads depend on the
switching fabric to provide the lowest possible latency — and to do
so predictably.
- Performance analysis – Beyond the need for high
bandwidth and low latency, measuring the performance of all 64 x
800GE links was an important aspect of the testbed, providing
deeper, actionable analytics around loss, latency, and jitter at
line rate. These valuable insights will help accelerate innovation
for data centers deploying future AI applications.
Rishi Chugh, Vice President of Product Marketing, Network
Switching, Marvell, said: “To definitively measure and validate
the low-latency capabilities of Teralynx 10, Marvell turned to
Keysight and its industry-leading AresONE-M 800GE test equipment.
Their thorough evaluation and collaboration with our team made the
process smooth and ensured the integrity of the strong results we
achieved.”
Ram Periakaruppan, Vice President and General Manager,
Network Test & Security Solutions, Keysight, said: “The
switching fabric is a vital component of the back-end network
architecture used for AI training. AI training workloads trigger a
huge increase in traffic volume and compared to front-end networks,
are persistently pushing this higher traffic volume around the
clock. At these sustained rates, benchmarking low latency becomes
very critical for ensuring that the AI training algorithms achieve
the most efficient job completion time.”
