Cisco bets on manufacturing in India amid global supply chain crisis

US networking giant Cisco Systems announced a manufacturing plant in India in an attempt to broaden its global supply chain.The factory is expected to be operational in 12 months and will generate $1 billion in total revenue including exports, said Cisco Chairman and Chief Executive Chuck Robbins.“We are announcing strategic investments in Indian manufacturing capabilities as the next step in delivering cutting-edge technologies to our customers in India and across the globe,” Robbins said in a press conference in New Delhi on Wednesday. “India is a focal point of innovation and business for Cisco, and we remain deeply committed to our partnerships here.”To read this article in full, please click here

MLAG Clusters without a Physical Peer Link

With the widespread deployment of Ethernet-over-something technologies, it became possible to build MLAG clusters without a physical peer link, replacing it with a virtual link across the core fabric. Avaya was one of the first vendors to implement virtual peer links with Provider Backbone Bridging (PBB) transport, and some data center switching vendors (example: Cisco) offer similar functionality with VXLAN transport.

Dell pushes security, devops integration in storage updates

Dell’s storage product lineup is set to receive a wide range of updates, including  devops integrations with the Ansible and Terraform tools, compliance with the latest US government security standards, zero trust readiness and more.PowerStore, Dell’s flash-based storage array line, is receiving the lion’s share of the security updates, according to a Dell announcement on Wednesday. Dell said that PowerStore now boasts STIG hardening, meaning that it is compliant with the federal government’s stanadards for its own networks. PowerStore also received secure and immutable snapshot technology, which should make for more reliable and harder-to-compromise recoveries. Multifactor authentication, streamlined file resiliency (which adds more mounted snapshots per system) and direct management of file permissions from within PowerStore are also being added.To read this article in full, please click here

Cisco Viptela drops the ball

In 2012, we saw the launch of Viptela, a pioneer in SDWAN network solutions. While they weren’t the first in SDWAN, I believe that badge goes to Talari; Viptela was the first company that caught my interest. I first saw what they were doing in 2015 on the Packet Pushers Podcast. Back then, the networking world was on fire with SDWAN offerings.

Sadly in 2017, Cisco purchased Viptela. I’m sure the leadership at Viptela was excited to be acquired by such a large networking company and hoped to develop Viptela to the pinnacle of their vision. But – despite calling themselves, and being repeatedly lamented for doing so, “a software company”, Cisco did what they so often do. They stopped platform development and tried to lower costs by integrating the vEdge software into their own. While I haven’t personally used the hybrid code, I haven’t heard good things from my coworkers. Eventually, we got the ISR1100 platform running Viptela code, but that was only a substitute for the vEdge 100 and 1000. We have still yet to see a replacement for the vEdge 2000.

US data center market nears full capacity

The North American data center market is at near capacity, which means that enterprises looking for colocation services may not be able to get the space they need at the data center they want, or they may have to pay a premium for it.Market researcher datacenterHawk, which helps companies search for colocation and cloud service providers, says that the North American data center market is facing record-high demand, although the rate of growth has slowed somewhat due to economic headwinds.High demand and low inventory (available space) have resulted in a vacancy rate in major North American markets of just 2.88%, according to datacenterHawk's 1Q 2023 Data Center Market Recap. In the secondary markets, it’s 5%.To read this article in full, please click here

How the coronation of King Charles III affected Internet traffic

How the coronation of King Charles III affected Internet traffic
How the coronation of King Charles III affected Internet traffic

When major events in a country happen Internet traffic patterns are often impacted, depending on the type of event. But what about the coronation of a king or queen? There’s no similar precedent, with a worldwide impact, in the Internet age, except maybe the coronation of the king of Thailand, in 2019. The last time it happened in the United Kingdom was 70 years ago (June 2, 1953), with Queen Elizabeth II; it was the first British coronation to be fully televised. Neither the Internet nor ARPANET were around at the time.

Imagine a grand royal event (if you saw the broadcast or the news, there’s no need), filled with pomp and pageantry, that's so captivating it impacts Internet traffic. That's what happened during the coronation of Charles III and Camilla, the newly crowned king and queen of the United Kingdom and other Commonwealth realms. As the coronation ceremony unfolded, on Saturday morning, May 6, 2023, there were clear spikes and dips in traffic, each coinciding with key moments of the ceremony.

Then came Sunday, and with it, the Coronation Big Lunch event. As the nation sat down to enjoy a communal meal throughout the country, Internet traffic took a Continue reading

Cisco warns of certificate problem that takes down SD-WANs

Cisco is warning customers that an expired certificate bug in a number of its Viptella SD-WAN devices can take down the boxes and consequently their attached SD-WAN environments.In a tweeted alert and a Tech Note Wednesday morning, Cisco said it is actively working to address a device failure problem that's impacting a number of Viptela SD-WAN platforms including the vEdge 100, 1000, 2000. It defined the problem as “an expired certificate affecting control plane connections, which eventually impacts data plane connections resulting in loss of service.”To read this article in full, please click here

Upcoming Course: Data Center Fabrics

On the 19th and 22nd (Friday and Monday) I’m teaching the two-part series on Data Center Fabrics and Control Planes over at Safari Books Online. This is six hours total training covering everything from Clos fabrics to eVPN.

Register here.

If you register for the course you can access a recording at a later date. From Safari:

This class consists of two three-hour sessions. The first session will focus on the physical topology, including a short history of spine-and-leaf fabrics, the characteristics of fabrics (versus the broader characteristics of a network), and laying out a spine-and-leaf network to support fabric lifecycle and scaling the network out. The first session will also consider the positive and negative aspects of using single- and multi-forwarding engine (FE) devices to build a fabric, and various aspects of fabric resilience. The second session will begin with transport considerations and quality of experience. The session will then consider underlay control planes, including BGP and IS-IS, and the positive and negative aspects of each. Routing to the host and the interaction between the control plane and automation will be considered in this session, as well. EVPN as an overlay control plane will be considered next, and finally Continue reading
