Google Cloud region planned for Warsaw

Google is looking to open a new data center region in Warsaw to better serve the enterprise market in Poland and the broader Central and Eastern Europe. The new Google Cloud region will have three zones to protect against service disruptions, and will launch with a portfolio of key products, including Compute Engine, App Engine, Google Kubernetes Engine, Cloud Bigtable, Cloud Spanner, and BigQuery.

Google has formed a strategic partnership with Poland’s Domestic Cloud Provider (DCP), which was founded jointly by PKO Bank Polski and the Polish Development Fund. DCP become a reseller of Google Cloud services.

Google Cloud customers are currently served by 20 cloud regions and 61 availability zones.

“This is an important moment for the Polish economy. We are very proud to partner with Google Cloud and to see them bring a new cloud region to Warsaw. Global enterprises are already building their competitive advantage on Google Cloud and now we will be able to offer customers in Poland the same advanced technology available worldwide,” said MichaƂ Potoczek, CEO of Domestic Cloud Provider. “We believe in a multi-cloud strategy. A Google Cloud region, together with our own infrastructure, will allow us to build hybrid services which will bring even more value to our customers.”

AT&T contributes Distributed Disaggregated Chassis white box to OCP

AT&T has contributed its specifications for a Distributed Disaggregated Chassis (DDC) white box architecture to the Open Compute Project (OCP). The contributed design aims to define a standard set of configurable building blocks to construct service provider-class routers, ranging from single line card systems, a.k.a. “pizza boxes,” to large, disaggregated chassis clusters.  AT&T said it plans to apply the design to the provider edge (PE) and core routers that comprise its global IP Common Backbone (CBB).

“The release of our DDC specifications to the OCP takes our white box strategy to the next level,” said Chris Rice, SVP of Network Infrastructure and Cloud at AT&T. “We’re entering an era where 100G simply can’t handle all of the new demands on our network. Designing a class of routers that can operate at 400G is critical to supporting the massive bandwidth demands that will come with 5G and fiber-based broadband services. We’re confident these specifications will set an industry standard for DDC white box architecture that other service providers will adopt and embrace.”

AT&T’s DDC white box design, which is based on Broadcom’s Jericho2 chipset, calls for three key building blocks:

  • A line card system that supports 40 x 100G client ports, plus 13 400G fabric-facing ports.
  • A line card system that support 10 x 400G client ports, plus 13 400G fabric-facing ports.
  • A fabric system that supports 48 x 400G ports. A smaller, 24 x 400G fabric systems is also included.

AT&T points out that the line cards and fabric cards are implemented as stand-alone white boxes, each with their own power supplies, fans and controllers, and the backplane connectivity is replaced with external cabling. This approach enables massive horizontal scale-out as the system capacity is no longer limited by the physical dimensions of the chassis or the electrical conductance of the backplane. Cooling is significantly simplified as the components can be physically distributed if required. The strict manufacturing tolerances needed to build the modular chassis and the possibility of bent pins on the backplane are completely avoided.

Four typical DDC configurations include:

  • A single line card system that supports 4 terabytes per second (Tbps) of capacity.
  • A small cluster that consists of 1 plus 1 (added reliability) fabric systems and up to 4 line card systems. This configuration would support 16 Tbps of capacity.
  • A medium cluster that consists of 7 fabric systems and up to 24 line card systems. This configuration supports 96 Tbps of capacity.
  • A large cluster that consists of 13 fabric systems and up to 48 line card systems. This configuration supports 192 Tbps of capacity.
  • The links between the line card systems and the fabric systems operate at 400G and use a cell-based protocol that distributes packets across many links. The design inherently supports redundancy in the event fabric links fail.


“We are excited to see AT&T's white box vision and leadership resulting in growing merchant silicon use across their next generation network, while influencing the entire industry,” said Ram Velaga, SVP and GM of Switch Products at Broadcom. “AT&T's work toward the standardization of the Jericho2 based DDC is an important step in the creation of a thriving eco-system for cost effective and highly scalable routers.”   

“Our early lab testing of Jericho2 DDC white boxes has been extremely encouraging,” said Michael Satterlee, vice president of Network Infrastructure and Services at AT&T. “We chose the Broadcom Jericho2 chip because it has the deep buffers, route scale, and port density service providers require. The Ramon fabric chip enables the flexible horizontal scale-out of the DDC design. We anticipate extensive applications in our network for this very modular hardware design.”
