Intel: Under attack, fighting back on many fronts

At first glance, Intel doesn’t look like a company under siege. In its last fiscal year, it recorded $77.8 billion in sales and $20 billion in profit. Its market capitalization is $220 billion as of mid-September 2021.And yet it is. When you’re the leader, all your competition is gunning for you. Intel is wrestling with a loss of leadership in manufacturing and process nodes, it’s losing share to a very resurgent AMD, an unrelenting Nvidia is challenging Intel for AI dominance, the Atom processor failed spectacularly against Arm in the mobile market, and it’s on its third CEO in three years. More about Intel: A closer look at two newly announced Intel chips Intel shifts to a multiarchitecture model Intel revises its chip terminology and branding CEO Gelsinger shakes up Intel But Intel revels in the competition. “Our success in so many markets makes us targets for lots of companies,” said Lisa Spelman, corporate vice president and general manager of the Xeon and memory group. “So it’s not a surprise that we have competitors that want a piece of that.” To read this article in full, please click here

How to add virtual-machine drive space in Microsoft Server Hyper-V

Virtualization is an essential part of modern IT infrastructure that presents many routine management tasks to sysadmins, among them increasing virtual hard-drive space when necessary. In my line of work, because of expanding log files, scaling for growing processes, and new tasks for existing servers, this is something I do at least once a month.Here’s how to do it in a Microsoft Server Hyper-V hypervisor running Windows Server 2016 using either Hyper-V Manager or Failover Cluster Manager.To read this article in full, please click here

Looking at your Linux system’s network interface with ethtool

The ethtool utility on Linux allows you to view and change some of your network-driver and interface-card settings, especially for wired devices. These include their speed, whether the interface uses auto-negotiation, and whether it runs in half- or full-duplex mode. Ethtool also provides an easy way to view or troubleshoot your network interface.More than likely, ethtool is already available on your Linux system. However, to check, you can use one or both of these commands:$ which ethtool /usr/sbin/ethtool $ sudo ethtool —version ethtool version 5.13 To get a sense of how this utility can control settings, run a command like the one below. The -h means “help”. You’ll likely find yourself looking at 10 pages or so of syntax like what is shown here.To read this article in full, please click here

Tape backup as a defense vs. ransomware

Tape is definitely not the best choice for primary recovery, but it does have features that make it a credible option for restoring systems and data that have fallen victim to ransomware without having to pay the ransom.The cloud has many more upsides than tape as a recovery tool in general, but there are circumstances where tape should be seriously considerd, and ransomware recovery is one of them.How to choose the best NVMe storage array When cloud’s not good enough Using the cloud for ransomware recovery—or not—has become somewhat of a religious discussion in many circles. Choosing the cloud offers many positive things, including cost, speed, and immediate availability—all great advantages when responding to a ransomware attack.To read this article in full, please click here

Supermicro updates one-socket server line

For the longest time, single-socket servers were the bottom of the server hierarchy, using "server" chips weaker than what you might find on a desktop. There were even servers that used the Atom processor. These were departmental servers doing the most menial of tasks, like file and print serving.But that's changing. Driven by high-core-count processors, and no doubt a desire to reduce costs, single-socket servers are getting some hefty workloads. AMD has led the way on this with its 32-core and 64-core EPYC processors that can do more with one chip than what a five-year-old dual-socket server can do. Dell has the servers available.To read this article in full, please click here

IBM ships high-density tape drives based on lastest spec

Fujifilm and Sony announced media last month, but IBM is the first with a drive.To read this article in full, please click here

Managing and monitoring swap space on Linux

Most of us don't often think about swap space unless we run into a problem on our systems that suggests we don't have enough. Even so, viewing and gauging the adequacy of swap space on a system is not overly complicated, and knowing what's normal for your system can help you spot when something is wrong. So let's check out some commands that can help you look into your swap space. But first, let's review some fundamentals.What swap space is and how it's used Swap space is disk space that acts something like an extension of memory. It gets used when the system's physical memory (RAM) is full and the system needs more memory resources. It's called "swap" because the system will move some inactive pages in memory into the swap space so that it can accommodate more data in RAM. In other words, it provides a way to free up RAM on a busy system.To read this article in full, please click here

Sleeping and waiting on Linux

The Linux sleep and wait commands allow you to run commands at a chosen pace or capture and display the exit status of a task after waiting for it to finish. Sleep simply inserts a timed pause between commands. Wait, on the other hand, waits until a process completes before notifying you that it has finished.Sleep The sleep command pauses for a specified time. It’s generally used in a script, but works on the command line as well. In the example below, sleep pauses a minute between the two date commands.$ date; sleep 60; date Wed Sep 8 12:10:40 PM EDT 2021 Wed Sep 8 12:11:40 PM EDT 2021 Summarizing your command-line usage on Linux The sleep command takes the numeric argument as the number of seconds. You can, however, ask it to sleep for various amounts of time by adding another character to the argument: 1m = 1 minute 2h = 2 hours 3d = 3 days $ date; sleep 1m; date Wed Sep 8 12:16:38 PM EDT 2021 Wed Sep 8 12:17:38 PM EDT 2021 In fact, you can sleep for less than a second if you need.To read this article in full, please click here

AWS, NetApp team up for a cloud-native file system

Amazon Web Services and NetApp have teamed up to tie NetApp’s on-prem storage and its proprietary OS for storage-disk arrays to AWS’s managed file-storage service, FSx.Called Amazon FSx for NetApp ONTAP, the service provides things like capacity scaling, maintenance, and updates so on-prem staff doesn’t have to. Performance management with automatic tiering between local storage and fully elastic AWS storage is provided by AWS as well. Learn about backup and recovery: Backup vs. archive: Why it’s important to know the difference How to pick an off-site data-backup method Tape vs. disk storage: Why isn’t tape dead yet? The correct levels of backup save time, bandwidth, space This is not a new area for AWS, which offers two similar services for Windows File Server and the Lustre HPC file-storage system. FSx for Windows File Server is a native Windows file system that offers Windows file storage in the cloud, while FSx for Lustre offers scalable, high-performance storage for HPC applications.To read this article in full, please click here

Western Digital announces a hybrid hard drive

Western Digital has announced a new disk drive architecture that combines flash memory with high-density hard-disk drives plus a small CPU to manage everything.If this sounds familiar, it is. Several years ago there was an effort by WD and other hard-disk drive (HDD) makers to build hybrid hard drives, with small flash drives acting as a cache for the hard disk, but those efforts failed, said Ravi Pendekanti, senior vice president of HDD product management and marketing at WD.Now see how AI can boost data-center availability and efficiency “There was a huge pitfall in those [drives],” he told me. The drives didn’t know what kind of data they had, so they didn’t know that hot data was frequently accessed and should be written on to the flash drive, while warm or cold that wasn’t accessed as much should be written to the disk.To read this article in full, please click here

Are Tesla’s Dojo supercomputer claims valid?

Self-driving cars must possess the ability to recognize road conditions, make decisions and take appropriate action, all in real time. This requires on-board artificial intelligence (AI) that ensures vehicles are able to “learn,” along with super-fast processing power.Tesla unveiled a custom AI chip back in 2019 and soon began manufacturing cars with it. Now Tesla has unveiled a second internally designed semiconductor to power the company’s Dojo supercomputer.Chip shortage will hit hardware buyers for months to years The D1, according to Tesla, features 362teraFLOPS of processing power. This means it can perform 362 trillion floating-point operations per second (FLOPS), Tesla says.To read this article in full, please click here

Using the Linux set command

The Linux set command allows you to change the value of shell options or to display the names and values of shell variables. Rarely used, it is a bash builtin, but is quite a bit more complicated than most builtins.If you use the command without any arguments, you will get a list of all the settings—the names and values of all shell variables and functions. Watch out though! You’ll end up with a torrent of output flowing down your screen. There are just short of 3,000 lines of output on my Fedora system:$ set | wc -l 2954 The top of the list looks like what you see below, but the output gets considerably more complicated as you move through it.To read this article in full, please click here
