Nvidia launches new hardware and software for on-prem and cloud providers

Published on 21st March, 2019, 12:00 PM

Nvidia used its GPU Technology Conference in San Jose to introduce new blade servers for on-premises use and announce new cloud AI acceleration.

The RTX Blade Server packs up to 40 Turing-generation GPUs into an 8U enclosure, and multiple enclosures can be combined into a "pod" with up to 1,280 GPUs working as a single system and using Mellanox technology as the storage and networking interconnect. Which likely explains why Nvidia is paying close to $7 billion for Mellanox.

Instead of AI, where Nvidia has become a leader, the RTX Blade Server is positioned for 3D rendering, ray tracing and cloud gaming. The company said this setup will enable the rendering of realistic-looking 3D images in real time for VR and AR.

Data center fiber to jump to 800 gigabits in 2019

Published on 20th March, 2019, 6:32 PM

The upper limits on fiber capacity haven't been reached just yet. Two announcements made around an optical-fiber conference and trade show in San Diego recently indicate continued progress in squeezing more data into fiber.

In the first announcement, researchers say they’ve obtained 26.2 terabits per second over the roughly 4,000 mile-long trans-Atlantic MAREA cable, in an experiment; and in the second, networking company Ciena says it will start deliveries of an 800 gigabit-per-second, single wavelength light throughput system in Q3 2019.

High-speed laser

MAREA, translated as “tide” in Spanish, is the Telefónica-operated cable running between Virginia Beach, Va., and Bilbao in Spain. The fiber cable, initiated a year ago, is designed to handle 160 terabits of data per second through its eight 20-terabit pairs. Each one of those pairs is thus big enough to carry 4 million high-definition videos at the same time, network-provider Infinera explains in an Optical Fiber Conference and Exhibition published press release.

Startups introduce new liquid cooling designs

Published on 20th March, 2019, 6:24 PM

With the increase in compute density making air cooling less and less feasible, liquid cooling is going mainstream. For data centers. Overclockers have been doing it for years.

For the most part, liquid cooling involves piping in cooled water to a heat sink attached to the CPU. The water then cools the heat sink, and is pumped away to be circulated and cooled down.

But there are some cases where immersion is used. That is where the entire motherboard is submerged in a nonvolatile liquid. Immersion is used in only the most extreme of cases, with the highest compute density and performance. For a variety of reasons, it isn’t widely used.

One startup that hopes to change that showed its wares at the Open Compute Project Summit 2019, which ran last week in San Jose. The OCP has a special project called Advanced Cooling Solutions to promote liquid cooling and other advanced cooling approaches.
