Emerson Network Power has launched its
first 40G AdvancedTCA payload blade. The ATCA-9405 provides telecom
equipment manufacturers with up to four times performance increaseover
previous generation ATCA blades for high touch and high throughput
packet processing applications in the latest data-intensive network
evolution, including lawful interception, network security, deep packet
inspection and cloud services.
Featuring dual OCTEON II CN6880 processors from Cavium, each
with 32 cnMIPS cores running at up to 1.5GHz, the Emerson Network Power
ATCA-9405 enables the implementation of packet processing applications
at line speeds of 40Gbps in conjunction with its range of 40G ATCA
The company says the ATCA-9405 has been designed to maximize the deep
packet inspection, security application processing and raw throughput of
the OCTEON processors. In addition to two 40G ATCA data fabric
connections that can operate active/active as well as active/standby,
the ATCA-9405 provides for direct Ethernet cable terminations of up to
82Gbps via a rear transition module (RTM) giving a total maximum
throughput of 328Gbps.
To help manage this, the blade's dual-core Freescale QorIQ P2020
processor implements sophisticated Ethernet switch management as well as
local management functions. Free of such system management overhead,
the OCTEON II processors can be dedicated solely to packet processing.
The new blade supports a variety of software, including Wind River's
Linux 4.x operating system, Cavium' s packet processing software
development kit, 6WIND's 6WINDGate fast path networking stacks, and
field proven L2 and optional L3 Ethernet switch management. The
ATCA-9405 can operate with or without rear transition modules depending
on system architecture, and is designed to support NEBS/ETSI
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
