How to inventory server storage with PowerShell

23:32
Making inventories of computer storage, particularly on severs, is complex due to the number of factors involved. There might be multiple physical media devices each of which contains multiple logical volumes. Volumes could span multiple disks with hardware or software-based RAID configurations. Each volume could be configured with its own drive letter, and folders throughout the file system could be shared on the network. Those inventories are important because gathering data on physical sto...

About that 'alarming' chip shortage — don't count on new fab plants to help quickly

22:13
A US Commerce Department report says the computer chip shortage is even worse than thought; at one point in 2021 there was just a five-day supply worldwide, and there's no sign the situation will improve anytime soon.

Hashing out the hash command on Linux

26.January
When you type “hash” on a Linux system, you could get one of two very different responses depending on the shell you are using. If you are using bash or a related shell such as ksh , you should see a list of the commands that you have used since your terminal session began, sometimes with a count of how many times each command was used. This can be more useful than using the history command if you just want to see your very recent command activity, but the hash command is not a single executa...

Meta plans the world’s fastest supercomputer for AI

26.January
Facebook’s parent company Meta said it is building the world's largest AI supercomputer to power machine-learning and natural language processing for building its metaverse project.

5G deployment near US airports slowed for now

24.January
5G deployments are proceeding around the country, albeit more slowly, after a partial agreement between the FCC and the FAA about the potential danger of 5G transmissions generated too strong and too close to airports on bandwidths adjacent to the spectrum used by airplane altimeters. President Biden announced that Verizon and AT&T had agreed to slow deployments of 5G around major airports after consultation with the Department of Transportation, in order to assuage concerns over air travel s...

The FCC has named 44 people to a technological advisory council tasked with exploring the possibilities of 6G wireless connectivity, a large proportion of the council’s members being drawn from the ranks of the country’s biggest networking-technology corporations. The chair of the committee will be a former Qualcomm executive, Dean Brenner. Intel, Cisco, Comcast, Microsoft, Nokia, Ericsson, and all of the major mobile operators are also represented on the commission’s Technological Advisory C...

BrandPost: FedRAMP Helps Secure Federal and Other Networks as They Transition to Cloud

21.January
By: Dolan Sullivan, Vice President of Federal at Aruba, a Hewlett Packard Enterprise company. Recently, it seems like you can’t go more than a few days without hearing about another significant cyberattack. From oil pipelines and meat producers to hospitals and city water supplies, no segment of our nation’s critical infrastructure is immune to hackers. As bad actors become more daring in their targets and more creative with their exploits, securing people, places, and things—wherever they ar...

BrandPost: Zero Trust Should Apply Everywhere

21.January
An old saying in sales is that "a confused mind does nothing." That truism certainly applies in the case of the zero-trust security model. Although a lot of people talk about zero trust, a far smaller percentage are actually doing anything about it. Because of the growing number of attacks, a philosophical shift from trusting everything on the network to not trusting anything (zero trust) makes sense. Zero-trust access ( ZTA ) operates on the assumption that threats both outside and inside th...

Edge computing in 2022: Double-digit growth

20.January
Worldwide spending on edge computing is expected to reach $176 billion in 2022, an increase of 14.8% over last year, according to new figures from analyst IDC. Edge computing started out rather modest in its use cases but has quickly expanded across industries and scope. Five years ago an edge network was a few mid-range servers in a ruggedized container. Now Nvidia and Lenovo are deploying GPU-based AI systems. “If we have learned anything over the last two years, the ability to quickly adap...

Cisco chases quantum tech

20.January
When it comes to hardcore quantum computing players Cisco might not be the first company you think of, but that could change a lot in 2022 and beyond. For starters, the company is investing in photonics development, which will enable quantum communications as well as other hardware and software technologies for quantum computing, networking, and cryptography. Developing quantum technologies was also one of the top predictions on the 2022 predictions list of Cisco’s executive vice president, g...

Backing up a database depends on how it’s delivered

20.January
How you back up your database depends three factors: how the database is delivered to you, the backup logistics of the database, and the recovery time objective (RTO) and the recovery point objective (RPO) you are attempting to meet. This article covers how the database is delivered. There are three ways databases can be delivered: as software on a server you own; as platform-as-a-service (PaaS); and as a serverless service. Let’s take a look at them. Traditional database software Until a few...

Intel sharpens focus on immersion cooling
