Liquid Cooling Gains Traction In Data Centers


All electronics generate heat, and that heat must be removed to ensure those electronics don’t overheat. Moving air has been the predominant approach for decades, with liquid cooling limited to particularly intense computing workloads, largely in the supercomputing domain. With the rise in AI, data-center power density has grown to the point where liquid cooling is now seeing a larger buil... » read more

Startup Funding: October 2023


Investors are betting heavily on data center technology, with October funding going to companies developing data processing units (DPUs) to accelerate a variety of tasks, a near-memory distributed dataflow architecture for AI, and liquid cooling technology. Much of this is linked to the build-out of the edge, closer to the source of the data than the cloud but not as compute-intensive. Other ... » read more

Startup Funding: May 2023


Photonic interconnects were an area of activity in May, with two companies raising funds for what could be much faster chip-to-chip and chiplet-to-chiplet links. Microstructured optics and metasurfaces also drew investment, with four companies creating products for a range of applications from flexible LEDs to multi-wavelength spectral imaging. The large language models that power many gener... » read more
