Progress with ODSA Chiplets and Bunch-of-Wires Interface

Bapi Vinnakota, project lead for the Open Compute Project's Open Domain-Specific Architecture (ODSA) initiative, provides an update on the chipset architecture following #OCPSummit2022 in San Jose, California. Two specs have been released this year. A mechanism to describe chiplets in XML was also discussed.

There was also a session on the Bunch-of-Wires interface.

Market drivers for Active Electrical Cables

Marvell has confirmed that  that leading cable manufacturers, including Amphenol, Molex, and TE Connectivity, are sampling to cloud data center operators their 100G/lane active electrical cables (AECs) powered by Marvell Alaska A PAM4 DSPs.

 At these speeds, the physical reach achievable with passive direct attach cables (DACs) falls short of the distance requirements for server-to-ToR (top of rack) and switch-to-switch interconnects. For cloud operators to continue their routine data center bandwidth doubling, most of these interconnects must transition from DAC to AEC. 

Marvell says the new AECs enable next-generation 400G, 800G and 1.6T server-to-switch and switch-to-switch interconnects that require 100G serial I/Os.

Marvell’s Alaska A family further applies advanced DSP equalization techniques and flexible firmware-based implementation to optimally compensate for the impairments introduced by the cable on the high-speed 100G PAM4 signal. This provides the ability to deploy thin cables that address the reach and flexibility needs of next-generation data center architectures.

Here is a over of the market from Venu Balasubramonian,  VP of product marketing, High Speed Connectivity and PHY Business Unit, Marvell.

1.6Tbps OSFP-XD AECs for hyperscale spines

Credo unveiled its 1.6Tbps OSFP-XD HiWire CLOS Active Electrical Cable (AEC) supporting lengths up to 2.75m in a thin, compact, cable form factor to support the dense spine switching requirements for next generation hyperscale data centers. 

The 1.6Tbps OSFP-XD AEC supports 16 bi-directional lanes of 112Gbps communication with an industry standard Attachement Unit Interface (AUI) on each end.  It supports cable lengths up to 2.75m using a compact 32AWG cable connecting the two ends that is no larger than two Cat6e cables.  The OSFP-XD AEC consumes less than 20W of power per end and offers the most reliable, lowest power interconnect for in-rack applications such as Distributed, Disaggregated Chassis (DDCs).

Don Barnetson, Vice President of AEC Product at Credo, provides an overview.

IDC maintains +2% forecast for worldwide IT services

International Data Corporation (IDC) is maintaining its forecast for 2% growth in nominal dollar denominated revenue this year for worldwide IT and business services. This corresponds to a 5.7% growth rate if measures in constant currency.

IDC maitains the forecast even against the backdrop of a global recession. Worldwide GDP growth has worsened since March/April and is now expected to grow by only 2.7% this year and 2.4% in 2023, based on August's figures. 

"While economic conditions for major economies around the world worsened in the last few months, given the services vendors' strong revenues, bookings, and other leading indicators, the worldwide services market will likely continue on its current growth trajectory," said Xiao-Fei Zhang, program director, IDC Worldwide Services Tracker program. "Also, the real threat to vendors may be from the supply side: with book-to-bill ratios above 1.1 or 1.15, attrition 25% plus, and utilization rate pushing close to 90%, something has to give. A cooler economy may actually help vendors to convert bookings to revenue faster by easing the labor market."

The 2022 market growth represents a slight increase of 12 basis points from IDC's April 2022 forecast. The five-year compound annual growth rate (CAGR) is now projected to be 5.2%, compared to the previous forecast of 4.9%.
