NVIDIA announced its next-generation accelerated computing platform with NVIDIA Hopper architecture, delivering an order of magnitude performance leap over its predecessor. Named for Grace Hopper, a pioneering U.S. computer scientist, the new architecture succeeds the NVIDIA Ampere architecture, launched two years ago. The company also announced its first Hopper-based GPU, the NVIDIA H100, packed with 80 […]

Data center SSD includes 176-layer NAND
Micron Technology, Inc. announced it is sampling the world’s first vertically-integrated 176-layer NAND solid-state drive (SSD) for the data center. The Micron 7450 SSD with NVMe delivers quality-of-service (QoS) latency at or below 2 milliseconds (ms),1 a wide capacity range, and the broadest set of form factors available to meet the needs of the most […]
New COM-HPC server modules target rugged environments with extended temperature ranges
congatec announces the availability of three new Server-on-Module families parallel to the launch of the brand-new Intel Xeon D processor family, formerly codenamed Ice Lake D. The new COM-HPC Server modules in Size E and Size D as well as the COM Express Type 7 modules will accelerate the next generation of real-time microserver workloads […]
Controller IC emulates ideal diode to boost reverse discharge protection
Diodes Incorporated has announced an ideal diode controller for system protection against reverse discharge. Emulating an ideal diode, by driving a P-channel MOSFET, the DZDH0401DW controller provides the high-side rail isolation necessary for reverse current blocking, in systems up to 40V. The compact size and high-performance capabilities of this arrangement mean that it is optimized […]
Gigabit Ethernet switch module hosts 26 ports
Curtiss-Wright’s Defense Solutions has introduced a new 26 port version of its popular PacStar 446 Gigabit Ethernet (GbE) switch module, the industry’s most compact solution for deploying high-density network access at the tactical edge powered by Cisco IOS-XE. The 26-Port PacStar 446, the newest addition to the PacStar Networking Systems family of tactical, battlefield, early entry, […]

How system fabric I/O interface cables and connectors are evolving
Newer fabric network input/output (I/O) cables and connectors support higher speeds, reduce latency, and support the latest interfaces — including the IEEE-802.3df Ethernet 200G per-lane specification project and modified versions, such as the RoCE and iWARP Ethernet. Other new cable and connector developments are working to include standard InfiniBand XDR 200G and modified versions, such […]
Simple double-duty: How to get one wire to do more, Part 1: The rationale
Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. It makes a lot of sense to use an individual single copper cable and its connection between two points to do more than it initially intended, especially if that additional function is aligned with the primary function […]
