Broadcom Tomahawk® 3 Powers Arista Networks’ New 400GbE Switching Systems
23 Octobre 2018 - 12:01PM
World’s highest-performance ethernet
switch-on-chip now shipping in production at the heart of Arista
7060X4 Series
Broadcom, Inc. (NASDAQ: AVGO), today announced that the
StrataXGS® Tomahawk
® 3 series is shipping as the
central switching chipset inside Arista Networks’ new 7060X4 Series
of 400GbE cloud networking platforms.
The new systems announced by Arista, providing 32 ports of
400GbE connectivity over OSFP or QSFP-DD optical interfaces in a
compact 1U hardware form factor, are each built using a single 12.8
Terabit/sec Tomahawk 3 BCM56980 device to provide full-duplex, line
rate switching and routing across all ports. The Tomahawk 3 Series
provides industry-leading 50G PAM-4 SerDes performance, the highest
available Ethernet I/O and packet processing bandwidth on a single
chip at 100/200/400GbE, as well as state-of-the-art buffering, load
balancing, high-availability and network telemetry capabilities,
tailored to the rigorous demands of software-defined cloud
networks. Combined with Arista’s robust, unified EOS® network
operating system and optical integration of OSFP and QSFP-DD
technologies, Tomahawk 3 enables the new 7060X4 systems to
accelerate adoption of 400GbE network infrastructure in the
cloud.
“Tomahawk 3 is an important catalyst for the build-out of 400
Gigabit Ethernet cloud networks,” said Andreas Bechtolsheim, Chief
Development Officer and Chairman of Arista Networks. “The four-fold
increase in Ethernet link speed and substantially lower power and
cost per bit enables cloud customers to build more scalable
next-generation network fabrics in a cost and power efficient
manner.”
StrataXGS Tomahawk 3 Series Product
Highlights:
- Supports line-rate, non-blocking 32 x 400GbE switching and
routing on a single chip, with fully flexible I/O configuration to
enable breakout to 64 x 200GbE ports, 128 x 100GbE ports, or any
combination thereof
- Delivers quantum leap in hyperscale network performance, CAPEX
and OPEX efficiency: 40% reduction in power per 100Gbps, and up to
75% lower cost per 100Gbps, versus alternatives
- New, state-of-the-art, integrated shared-buffer architecture
offers 3X to 5X higher incast absorption and provides the highest
performance and lowest end-to-end 99.9% latency for RoCEv2 based
workloads
- Industry-leading Broadview™ Gen 3 integrated network
instrumentation feature set and software suite, providing full
visibility to network operators into packet flow behavior, traffic
management state, and switch internal performance
- Comprehensively supports all packet processing and traffic
management requirements for cloud-scale network use cases: up to
Million-route forwarding scale, doubled ECMP scale, Dynamic Load
Balancing and Group Multipathing, In-Band Network Telemetry,
Elephant Flow detection and re-prioritization
- Robust connectivity using 256 instances of the industry’s best
performing and longest-reach 50G PAM-4 integrated SerDes core,
enabling long-reach (LR) East-West optical links and
Direct-Attached-Copper (DAC) in-rack cabling in the data center,
fully compliant to new IEEE standards for 50/100/200/400GbE
- Multiple switch device variants at 12.8 Tbps (32x400GbE /
128x100GbE), 8.0 Tbps (48x100GbE + 8x400GbE), and 6.4 Tbps
(16x400GbE / 64x100GbE), providing optimized performance, cost, and
power based on application use case
- Implemented with unparalleled silicon area and power
efficiency; qualified and shipping in volume on proven 16nm process
technology node
