The Department of Energy has awarded $40 million to 15 vendors and university labs as part of a government program that aims to reduce the portion of data centers' power usage that's used for cooling to just 5% of their total energy consumption.The DOE's Advanced Research Projects Agency–Energy (ARPA-E) is providing the funding to jumpstart a program called COOLERCHIPS, an acronym for Cooling Operations Optimized for Leaps in Energy, Reliability, and Carbon Hyperefficiency for Information Processing Systems.For chip cooling to account for just 5% of total energy consumption, that would translate to a PUE of 1.05. (Power usage effectiveness, or PUE, is a metric to measure data center efficiency. It’s the ratio of the total amount of energy used by a data center facility to the energy delivered to computing equipment.)To read this article in full, please click here

System memory is a complex problem. More memory means more performance, especially in a virtualized environment. But more memory also requires more power, and that can add up as you start to get into thousands of memory sticks.Plus, you can only put so many memory sticks in a server, depending on the number of slots available. So how do you increase memory capacity? By increasing memory density on the chips, which is easier said than done. However, a startup called NEO Semiconductor is claiming it will be able to increase memory density by up to eight times over standard memory with a breakthrough 3D design.It’s not a new concept; 3D memory stacking has been used in NAND flash to increase capacity for a decade now. Memory transistors can only be so large to fit in the confines of a DRAM chip. Rather than an increase the number of transistors laid out side by side, memory makers began stacking it on top of each other, thus increasing capacity in the same physical space. In the 10 years since 3D stacking began, NAND flash DRAM has reached the 170-layer mark, and SSDs have seen a significant increase in capacity without Continue reading
For online auction powerhouse eBay, customer service is everything. Or, as Parantap Lahiri, vice president of network and data center engineering, puts it, “We want to make the network more like air or water, so our people don’t have to worry about network resources when creating magical services for our users.”The demands on the eBay infrastructure are staggering: 1.8 billion active listings; 133 million active buyers. It’s main landing page gets 250 million visits per day. Unlike a static storefront site like Amazon, an eBay auction can entail multiple bidders from all over the world competing against each other as the clock ticks down to the end of the auction. And the eBay platform supports direct communication between sellers and buyers, with offers and counteroffers flying back and forth.To read this article in full, please click here

The grep command makes it easy to find strings in text files on Linux systems, but that's just a start. It can be used to search through these files for multiple strings or regular expressions at the same time. It can also ignore case when needed, and it can count the lines in the resulting output for you. This post shows how to use grep in all these ways.Basic grep
The simplest grep command looks like the one shown below. This "find string in file" command will show all the lines in the file that contain the string, even when that string is only part of a longer one.$ grep word story
The wording suggests there was more to the story than anyone wanted to admit.
The sword had been left behind the shed. It was several days before it was
Finding multiple strings
There are a number of ways to search for a group of strings in a single command. In the command below, the '|' character serves as an "or" function. The command will display any lines in the file that contain the word "xray", the word "tape" or both.To read this article in full, Continue reading
In this Linux tip, we’re going to look at the netstat -s command that displays network statistics. The numbers reflect activity since the system’s last boot so some counts will change fairly frequently.
Dell’s storage product lineup is set to receive a wide range of updates, including devops integrations with the Ansible and Terraform tools, compliance with the latest US government security standards, zero trust readiness and more.PowerStore, Dell’s flash-based storage array line, is receiving the lion’s share of the security updates, according to a Dell announcement on Wednesday. Dell said that PowerStore now boasts STIG hardening, meaning that it is compliant with the federal government’s stanadards for its own networks. PowerStore also received secure and immutable snapshot technology, which should make for more reliable and harder-to-compromise recoveries. Multifactor authentication, streamlined file resiliency (which adds more mounted snapshots per system) and direct management of file permissions from within PowerStore are also being added.To read this article in full, please click here
The North American data center market is at near capacity, which means that enterprises looking for colocation services may not be able to get the space they need at the data center they want, or they may have to pay a premium for it.Market researcher datacenterHawk, which helps companies search for colocation and cloud service providers, says that the North American data center market is facing record-high demand, although the rate of growth has slowed somewhat due to economic headwinds.High demand and low inventory (available space) have resulted in a vacancy rate in major North American markets of just 2.88%, according to datacenterHawk's 1Q 2023 Data Center Market Recap. In the secondary markets, it’s 5%.To read this article in full, please click here

There are a number of ways to view files on Linux, because, after all, files on Linux are multifaceted. They have names, they have content, they have access permissions, and they have dates and times associated with their "birth" (when they were initially added to the file system) as well as when they were last changed and last accessed. This post covers the commands that allow you to view all these details.Listing files
The easiest and most obvious way to list files is with the ls command. By default, ls will list files in the current directory in name order, but you can reverse that by adding the -r option.To read this article in full, please click here
Broadcom said it will spend $2 billion a year to accelerate research and development for VMware products and services.In making the investment assurance, Broadcom CEO Hock Tan wrote in a blog post: “By extending our multi-cloud strategy, we will invest in extending VMware’s software stack to run and manage workloads across private and public clouds, which means any enterprise can run application workloads easily, securely, and seamlessly on-prem, or in any cloud platform they prefer.”“If companies can run VMware as a private cloud on-prem, they should be able to take their same application workloads to the public cloud without needing to re-engineer that application or worry about being locked into the public cloud providers that they choose,” Tan stated.To read this article in full, please click here

Today’s enterprise networks span on-premises and cloud environments, and it has become a lot harder for IT teams to maintain performance, reliability and security when some parts of the network are unknown or off-limits to traditional performance monitoring tools.“If you cannot get visibility into all the components comprising the digital experience, everything that is between the end user clicking the mouse to the deepest part of a cloud or data center network, then you are flying blind, you are incurring a lot of risk, and you could be overspending, too,” says Mark Leary, research director for network analytics and automation at research firm IDC.To read this article in full, please click here
You probably use some bash builtins fairly often whether or not you think of them as builtins or simply as commands. After all, bash builtins are commands, but not implemented as separate executables. Instead, they are part of the bash executable. In other words, they are "built into" bash, thus the term "bash builtins".If you're looking for a particular builtin, the which command isn't going to find it for you because it only looks through a collection of executables. This includes system commands like /bin/echo as well as scripts for which you have execute permission. Here's an example of which not finding anything:To read this article in full, please click here
IBM is now offering bare metal instances in the cloud powered by its LinuxONE hardware with a pitch that enterprises can consolidate workloads and reduce energy consumption compared to x86 servers under similar conditions.The LinuxONE servers feature the Telum processor that IBM uses in its z16 mainframe, but they're designed to run multiple flavors of enterprise Linux rather than the mainframe z/OS.IBM shipped the fourth generation of its LinuxONE product line last September, dubbed LinuxONE Emperor, promising both scale-out and scale-up performance and requiring a lot less hardware than standard x86 servers. More recently, it introduced LinuxONE Rockhopper, a smaller-scale system for more modest deployments.To read this article in full, please click here
