BrandPost: What do music and SD-WAN have in common?

By: Nav Chander, Head of Service Provider SD-WAN/SASE Product Marketing at HPE Aruba Networking.This is part 2 of a 3-part blog series on SD-WAN, SSE, and multi-cloud networking (MCN), where we will highlight how these 3 technology areas are analogous to 3 different musical instruments that can be played separately. The first blog focused on MCN, and this blog focuses on SD-WAN technology.So, let’s first explore our second instrument the guitar, an instrument which will symbolize SD-WAN, an important foundation for building a modern enterprise WAN network that supports secure connectivity and high performance for business applications. The macro driver of SD-WAN is the digital transformation effort worldwide which is manifested by enabling an efficient, cloud-first IT strategy.To read this article in full, please click here

Are HDDs greener than SSDs?

Here’s a wrinkle in corporate environmental efforts. Futurum Research is backing a recently published academic paper that suggests hard disk drives (HDD) could be greener than solid state drives (SSD) when taking into consideration the manufacturing process.The paper in question is called “The Dirty Secret of SSDs: Embodied Carbon” and was published last year by Swamit Tannu, computer science professor at the University of Wisconsin-Madison, and Prashant J. Nair, an assistant computer science professor at the University of British Columbia.The paper states that the biggest carbon emissions happen at the time of manufacture, with production of SSDs generating much more carbon than disk drives of equal capacity.To read this article in full, please click here

HS055 Cloud Is Not The Only Future ?

A special guest today, Keith Townsend joins Johna Greg to discuss the advantages and disadvantages of cloud computing compared to on-premises infrastructure. We start by clarifying the definition of cloud and emphasizing the significance of software-defined infrastructure and automation in on-premises data centers. Keith shares his perspective on hybrid infrastructure and making the case for a combination of on-premises and off-premises resources as the future of enterprise IT.

Intel partners with former acquisition target Tower Semiconductor

Weeks after Intel’s proposed $5.4 billion acquisition of Israel-based Tower Semiconductor fell apart, the two firms announced plans for Intel to provide foundry services to its former acquisition target.As part of the deal, Tower will invest up to $300 million to acquire and own equipment and other fixed assets at Intel’s New Mexico fabrication plant. Tower will eventually have a capacity of over 600,000 photo layers per month to manufacture its analog CMOS chips.Tower already owns fabs in Israel, the U.S., and Japan, and it plans to launch in Italy soon. But the existing fabs create 200 mm wafers. The New Mexico facility will create 300 mm wafers, increasing production quantity.To read this article in full, please click here

Using the comm command to compare files or directories on Linux

The comm command on Linux systems can compare file or directory contents and display the differences in a clear and useful way. Think of “comm” not so much as a reference to “compare” as to “common,” since the command writes to standard output both the lines that are common and the lines that are unique in each of the files or directories.One key requirement when using comm is that the content to be compared must be in sorted order. However, there are ways that you can get away with comparing content that isn’t sorted. Some examples of how to do this will be presented in this post.Comparing files Normally, when using the comm command, you would compare two sorted text files to see their shared and unique lines. Here’s an example in which a list of friends and a list of neighbors are compared.To read this article in full, please click here

Enterprise DPU advances are spurred by AI, security, networking apps

The use of data processing units (DPU) is beginning to grow in large enterprises as AI, security and networking applications demand greater system performance.Much DPU development to date has been aimed at hyperscalers. Looking ahead, DPU use in the data center and elsewhere in the enterprise network is expected to grow. One way that could happen is the melding of DPU technology with networking switches – a technology combination AMD Pensando calls a “smartswitch.”An early entrant in that category is HPE Aruba’s CX 10000, which combines DPU technology from AMD Pensando with high-end switching capabilities. Available since early 2022, the CX 10000 is a top-of-rack, L2/3 data-center box with 3.6Tbps of switching capacity. The box eliminates the need for separate appliances to handle low latency traffic, security and load balancing, for example.To read this article in full, please click here
