Data-center power consumption holds steady

By on • ( Leave a comment )

A study published in the journal Science last week, notes that while global data-center energy consumption has risen over the past decade, a predicted explosion in power consumption by data centers has not manifested thanks to advances in power efficiency and, ironically enough, the move to the cloud. Data centers accounted for about 205 terawatt-hours of electricity usage in 2018,  roughly 1% of all electricity consumption worldwide. This represents a 6% increase in total power consumption since 2010, while global data center compute instances rose by 550% over that same time period.

400G QSFP-DD DR4 module is powered by silicon photonics technology

Hengtong Rockley has released a 400G QSFP-DD DR4 optical module based on silicon photonics technology geared for cloud data center networks. The new 400G QSFP-DD module is the company’s first 400G silicon photonics optical module product and is intended for use in next generation cloud-scale data center networks for low-cost, low-power consumption optical connections between switches. The deployment of such 400G transceivers will enable data center networks to deliver a 4x increase in network speed compared to existing deployments using 100G.

Applications for singlemode fiber-optic cabling

By on • ( Leave a comment )

Singlemode fiber-optic cabling systems, once found almost exclusively in service providers’ long-haul networks or in expansive campuses, are now commonly being used in data center and enterprise networks. How deep has singlemode gotten into these networks, and how much deeper are they likely to go? That’s the topic of this month’s In-Depth discussion.In the data center and the enterprise, long-wavelength transmission supported by singlemode fiber-optic cabling systems serve today’s networking needs and hold promise for tomorrow.

Hyperscale Data Center Drives the Global Cloud Revolution

The rise of hyperscale computing has created a new paradigm in the data center business, changing the landscape for providers and customers alike. Hyperscale companies have become the largest customers for leasing wholesale and build-to-suit data center space. As a result, these customers hold huge sway over data center development, which has evolved rapidly to adapt to larger requirements. Download the special report.

Cabling considerations for CORD networks

By on • ( Leave a comment )

In the midst of edge computing and the growing role of edge data centers, a practice has emerged that frequently goes by its acronym, CORD. CORD stands for central office rearchitected as a data center. In a CORD deployment, a service provider uses an existing facility that has served as a central office. In some cases, these facilities now serve as headends for the service providers’ microwave towers or land lines.

Stop Guessing, Start Testing

For co-lo data center operators infrastructure reliability and emergency response capability is essential — downtime is not an option. In this environment, testing is a critical element in meeting customer service level agreements (SLAs) and/or internal performance objectives. In a modern data center, there are thousands of links, cables, transponders, and connections, or, to it put frankly: thousands of potential points of failure. The following is a list of common key test use cases for DCOs.
