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

DHCP: How to work with user classes on Windows

Whether in an existing network or a new one, there is an aspect of design that cannot be skipped: deciding if handing out IP addresses will be dynamic (automatic) or manual (one-by-one) or—the most common—a combination of the two.By choosing to distribute them dynamically you are choosing to use a dynamic host configuration protocol (DHCP) service somewhere on your network, and there can be some tricks to that regardless of what server you use. For this discussion, I will describe how to use user classes on a Windows DCHP Server to specify a range of IP addresses and to assign range-specific DHCP options.To read this article in full, please click here

What to expect from SASE certifications

Secure access service edge (SASE) is a network architecture that rolls SD-WAN and security into a single, centrally managed cloud service that promises simplified WAN deployment, improved security, and better performance.According to Gartner, SASE’s benefits are transformational because it can speed deployment time for new users, locations, applications and devices as well as reduce attack surfaces and shorten remediation times by as much as 95%.With the pandemic, adoption of SASE  has been on an upward swing. A June report from Sapio Research, commissioned by Versa Networks, finds 34% of companies are already using SASE, and another 30% plan to in the next six to 12 months.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
