COVID-19: Tech giants, government agencies add supercomputing to the fight

By on • ( Leave a comment )

High-powered computer-industry players, government entities and universities are teaming up to further technology that can be used in the fight against the spread of the COVID-19 virus. The idea is to meld the high-performance computing systems supported by consortium members to let researchers run massive amounts of epidemiology, bioinformatics, and molecular modeling calculations. These experiments would take years to complete if worked by hand, or months if handled on slower, traditional computing platforms, according to IBM.

Ethernet consortium announces completion of 800GbE spec

By on • ( Leave a comment )

The Ethernet Technology Consortium has announced the completion of a specification for 800 Gigabit Ethernet technology. Based on many of the technologies used in the current top-end 400 Gigabit Ethernet protocol, the new spec is formally known as 800GBASE-R.The 800GbE spec adds new media access control (MAC) and physical coding sublayer (PCS) methods, which tweaks these functions to distribute data across eight physical lanes running at a native 106.25Gbps. The 800GBASE-R specification is built on two 400 GbE 2xClause PCSs to create a single MAC which operates at a combined 800Gbps.

Speed race: Just as 400Gb Ethernet gear rolls out, an 800GbE spec is revealed

Just as the stage is set for 400G Ethernet (GbE) to roll out in force later this year, mainly in hyperscale, telco and large data-center networks, there is a call to boost that speed to 800GbE or even higher in the coming years.The need for increased speed in data centers and cloud services speeds is driven by many things including the continued growth of hyperscale networks from players like Google, Amazon and Facebook, but also the more distributed and mobile workloads modern networks support. But the reality on the ground is that much lower speeds are what’s commonly in use.

Simplifying Data Center Network Design with Universal Fiber Cassettes

Polarity is a critical part of any fiber network. Polarity means that a fiber optic link’s transmit signal at one end of the cable must match the corresponding receiver at the other end. While this concept might seem simple, it becomes more complex with multifiber cables and MPO connectors. Leviton’s new Universal Polarity Fiber Cassettes allow for the same interchangeable cassette on both ends of a Method B trunk in a fiber channel, reducing the complexity of a fiber network, ensuring consistent polarity, and streamlining network deployment.

400GbE-LR8 QSFP-DD compact pluggable interfaces succeed in client-side services trial

Windstream Wholesale and Infinera marked an industry-first with their successful trial of LR8-based 400GbE client-side services. The trial was powered by Infinera’s Groove G30 platform. The trial leveraged Infinera’s commercially available 2x 600G Wavelength muxponder on its Groove (GX) G30 Compact Modular Platform with the CHM-2T sled, which enabled the customer-facing 400GbE service to be transmitted using a single-carrier 600G wavelength.

Designing Fiber Optic Connectivity for TOR

In today’s fast-changing data center environment, where compute performance and storage volume increase significantly every year, it is important to step back and review why top-of-rack (TOR) fabric is deployed by more than 50% of data centers worldwide.
Using a TOR architecture is more relevant than ever to keep up with these changes. TOR supports and enables change as a part of your data center infrastructure management (DCM) plan, a paramount strategy in today’s conditions.
