By: Gabriel Gomane, Senior Product Marketing Manager at Aruba, a Hewlett Packard Enterprise company.For organizations coming out of government-mandated restrictions as a result of the COVID-19 crisis, they have an opportunity to reimagine their respective digital transformation journeys and become more resilient for coping with constant business change. Of course, not all businesses have survived, or thrived, during the past two-plus years. However, each must chart their own course in how they continue to digitize pieces or entire business functions. Key to that digital transformation is SD-WAN, especially as organizations rebound and climb out of the crisis, a crisis that may come roaring back considering the continued threat of new variants and outbreaks across the globe. In the meantime, here are five trends influencing SD-WAN that organizations can leverage to future-proof the business.To read this article in full, please click here

The winners of a critical FCC auction for midband spectrum that ended last November have received their official grants of license to use the airwaves for which they spent a total of $22.4 billion, the FCC announced Wednesday.A total of 4,041 licenses were issued to 23 different bidders, according to the commission. Licensees hoping to use the spectrum for 5G rollouts still have to reimburse incumbent non-federal users of the band, which had been in use for radiolocation purposes, and the FCC said that further details about those costs would be laid out in a subsequent filing.Auction 110 saw the government sell off 100MHz of spectrum in the midband — around the 3.45GHz range — divided into 10 10MHz blocks for each Partial Economic Area or PEA that the FCC adopted in 2014. (There are 416 PEAs covering the US, meaning that 119 specific licenses were not sold in the auction.)To read this article in full, please click here

Interest in deploying a private 5G network is growing among enterprises, but mainstream deployment faces a number of obstacles, including competition from less complicated and more widely available wireless options such as Wi-Fi 6/6E.Private 5G could be a game changer for some enterprises, particularly in the industrial, automotive, and energy sectors. A private 5G network can guarantee throughput and latency levels that next-generation use cases require, according to research firm Gartner. But it’s still very early in the private-5G game. It could take a decade for it to take hold, as 5G coverage needs to expand and costs for 5G subscription plans and capable devices need to come down.To read this article in full, please click here
It comes as a big surprise to many people when their restores are slower than their backups, but it should be no surprise at all. In fact, everyone should plan for this disparity and build into their backup design.There are a number of reasons why restore speeds are typically slower than backup, and here is an explanation of five of them.

Worldwide semiconductor revenue is set to increase by 13.6% this year as demand continues to exceed supply, according to a Gartner Research report.That growth will likely level off in 2023, however, with just a 3.6% increase predicted for that year, noted the report, which was released Tuesday. It's a function of overall supply and demand coming into near-balance in the future, according to Gartner.The chip shortage that has created widespread supply constraints in the recent past is beginning to ease, although some sectors — most notably the automotive industry – will still see demand outstripping supply for the foreseeable future.Alan Priestley, the report's author and a research vice president at Gartner, said that automotive semiconductor demand will grow despite flaccid overall vehicle production.To read this article in full, please click here
A storage area network (SAN) is a dedicated, high-speed network that provides access to block-level storage. SANs were adopted to improve application availability and performance by segregating storage traffic from the rest of the LAN. SANs enable enterprises to more easily allocate and manage storage resources, achieving better efficiency. “Instead of having isolated storage capacities across different servers, you can share a pool of capacity across a bunch of different workloads and carve it up as you need. It’s easier to protect, it’s easier to manage,” says Scott Sinclair, senior analyst with Enterprise Strategy Group.To read this article in full, please click here

Why is it that over 90% of enterprises tell me that they expect to spend more on security over the next three years, and almost 60% say they expect to spend less on networking? We obviously think that network technology is getting more efficient, more competitive. Why isn’t that the case for security? The short answer is that enterprises have been chasing acronyms and not solutions.Acronym-chasing comes about because by nature, security is hard to plan for. The average network expert finds out there’s an issue because some higher-up reads or hears about a breach. Maybe they do a quick search, and they find out that what they really need is SASE. Or maybe they need SSE, which we’re told is SASE without SD-WAN. In any event, what happens is that there’s pressure to add this new thing on, and that creates another layer of protection...maybe. Complication and cost? Surely.To read this article in full, please click here
