Cutting To The Front Of The Server CPU Line

In case you haven’t figured it out yet, if you are not one of the hyperscalers or one of the biggest cloud builders, then you are a second class citizen, or maybe even third class, when it comes to the semiconductors that go into different part of the systems that run your organization. …

Hedge 153: Security Perceptions and Multicloud Roundtable

Tom, Eyvonne, and Russ hang out at the hedge on this episode. The topics of discussion include our perception of security—does the way IT professionals treat security and privacy helpful for those who aren’t involved in the IT world? Do we discourage users from taking security seriously by making it so complex and hard to use? Our second topic is whether multicloud is being oversold for the average network operator.

AMD posts operating loss, but solid growth for data center, embedded segments

AMD announced third quarter results this week, and while it posted a $64 million loss in terms of overall operating income—mainly due to its acquisition of Xilinx—but large gains in the company’s data center, embedded and gaming segments provided an encouraging note.Total revenue rose by 29% for the third quarter of 2022, to $5.56 billion from $4.31 billion one year ago. Gross profit also rose in year on year terms, from $2.08 billion in last year’s third quarter to $2.35 billion for the past three months. The decline in operating income was caused by much higher operating expenses, which more than doubled in the third quarter, rising from $1.14 billion a year ago to $2.42 billion in the most recent figures.To read this article in full, please click here

HPE launches 11th generation ProLiant servers

Hewlett Packard Enterprise has introduced the 11th generation of its ProLiant servers designed for a range of modern workloads, including AI, analytics, cloud-native applications, graphic-intensive applications, machine learning, Virtual Desktop Infrastructure (VDI), and virtualization.The new ProLiants have three processor options: AMD Epyc “Genoa” generation processors, Intel Xeon Scalable “Sapphire Rapids” generation processors, and Ampere Altra and Altra Max cloud-native processors.Compared to the previous server generation, the new HPE ProLiant Gen11 servers support twice as much I/O bandwidth and 33% more high-performance GPU density per server to support AI and graphic-intensive workloads than the prior generation.To read this article in full, please click here

Cisco, Red Hat team to streamline hybrid-cloud container management

Cisco and Red Hat have expanded their partnership to include a new combination that lets customers more easily turn-up and manage bare-metal containerized workloads.The companies have integrated Cisco’s cloud-operations management platform, Intersight, and Red Hat OpenShift Assisted Installer, which controls OpenShift clusters, to handle the complex and time-consuming process of networking a containerized environment.Nearly 80% of enterprises have adopted containers in production environments, and containers are especially effective when they are migrated across different hybrid-cloud domains—on-premises data centers, colocation facilities, network edge, and public clouds, wrote Dhritiman “DD” Dasgupta, vice president of  product management for Cisco’s Cloud and Compute team in a blog about the integration. To read this article in full, please click here

Cloudflare is not affected by the OpenSSL vulnerabilities CVE-2022-3602 and CVE-2022-3786

Cloudflare is not affected by the OpenSSL vulnerabilities CVE-2022-3602 and CVE-2022-3786
Cloudflare is not affected by the OpenSSL vulnerabilities CVE-2022-3602 and CVE-2022-3786

Yesterday, November 1, 2022, OpenSSL released version 3.0.7 to patch CVE-2022-3602 and CVE-2022-3786, two HIGH risk vulnerabilities in the OpenSSL 3.0.x cryptographic library. Cloudflare is not affected by these vulnerabilities because we use BoringSSL in our products.

These vulnerabilities are memory corruption issues, in which attackers may be able to execute arbitrary code on a victim’s machine. CVE-2022-3602 was initially announced as a CRITICAL severity vulnerability, but it was downgraded to HIGH because it was deemed difficult to exploit with remote code execution (RCE). Unlike previous situations where users of OpenSSL were almost universally vulnerable, software that is using other versions of OpenSSL (like 1.1.1) are not vulnerable to this attack.

How do these issues affect clients and servers?

These vulnerabilities reside in the code responsible for X.509 certificate verification - most often executed on the client side to authenticate the server and the certificate presented. In order to be impacted by this vulnerability the victim (client or server) needs a few conditions to be true:

  • A malicious certificate needs to be signed by a Certificate Authority that the victim trusts.
  • The victim needs to validate the malicious certificate or ignore a Continue reading

Scalability Aspects of SR-MPLS

Henk Smit left a wonderful comment discussing various scalability aspects of SR-MPLS. Let’s go through the points he made:

When you have a thousand routers in your networks, you can put all of them in one (IS-IS) area. Maybe with 2k routers as well. But when you have several thousand routers, you want to use areas, if only to limit the blast-radius.

Absolutely agree, and as RFC 3439 explained in more eloquent terms than I ever could:

Comparing QUIC and TCP

QUIC could be seen as a simple update to TCP, but I think that such a vew is missing the point of QUIC. QUIC represents a significant shift in the set of transport capabilities available to applications in terms of communication privacy, session control integrity and flexibility.

Ubuntu 20.04 image for EVE-NG – Python for Network Engineers

This is an identical copy of my Ubuntu 20.04 PFNE Docker image, developed to be imported and used on EVE-NG (works also on the Community edition because it doesn’t need Docker support). It contains all necessary tools for network engineers to test automation and learn Python. If you think a tool would be suitable to … Continue reading Ubuntu 20.04 image for EVE-NG – Python for Network Engineers

NetApp unifies its storage offerings under a new BlueXP roof

NetApp announced Tuesday that its on-premises and cloud storage offerings are now unified under the umbrella of a single platform, called BlueXP, which serves as a control plane for each of its products and simplifies the management of enterprise storage for organizations.BlueXP—which is a free upgrade for its customers—is a reaction to the reality that more and more companies’ storage environments are hybrids these days, combining cloud and on-premises storage, according to NetApp. Businesses of almost any size that have been in operation for more than a decade or so are, more often than not, involved in digital transformation efforts that move at various paces, said company senior vice president and general manager for cloud storage Ronen Schwartz.To read this article in full, please click here
