AMD Finishes Out The Zen4 Server CPUs With Edgy “Siena”

Different workloads need different mixes of price, performance, thermals, and longevity in the field out there on the edge and in the datacenter, and that is why server CPU makers for years have had a mix of processors that deliver on these vectors that are different from each other. …

VMware NSX Bare Metal Edge Performance

Every cloud environment is rooted in virtualization and is defined by three pillars: network virtualization, server virtualization, and storage virtualization. The VMware NSX Edge Node plays an essential role in virtualizing networking and security services. The throughput supported by the NSX Edge Node is critical for the entire ecosystem and network services running on it.

In this blog, we outline NSX Bare Metal Edge performance for customers implementing Bare Metal Edge for their virtual networking infrastructure.  Using NSX Bare Metal Edge (with no services running) with 4x100Gbp interfaces, RFC2544 performance tests yielded a North-South throughput of up to 388 Gbps (97%-line rate) and up to 3 Tbps for the entire cluster (when using 8 Edge Nodes), providing significant throughput for North-South traffic in the virtual network infrastructure.

Please refer to VMware NSX Bare Metal Edge Performance white paper for more information on test and settings used to achieve these results.

Key Hardware Considerations for NSX Bare Metal Edge

The choice of hardware for the NSX Bare Metal Edge is driven by bandwidth requirements and the throughput you want to achieve. Key considerations include:

• Physical NIC: Consider the bandwidth, connectivity, and resiliency requirements for the Bare Metal Edge.
• CPU: NSX Continue reading

IoT startups fill security gaps

As the volume of IoT devices connecting to enterprise networks continues to climb, the number of security threats has been increasing in lockstep. Cybersecurity threats, alongside supply chain issues, chip shortages and geopolitical instability, are a major reason that IoT growth has been slower than many analysts had predicted.Even so, the scale of the IoT security problem is great enough that 52 IoT startups raised a total of $840 million in the latest quarter, and even cautious analysts believe the IoT market will grow steadily in the coming years. In fact, research firm IDC predicts that the IoT market will expand to 55.7 billion connected IoT devices by 2025, with those devices generating 80B zettabytes (ZB) of data.To read this article in full, please click here

Dataplane MAC Learning with EVPN

Johannes Resch submitted the following comment to the Is Dynamic MAC Learning Better Than EVPN? blog post:

I’ve also recently noticed some vendors claiming that dataplane MAC learning is so much better because it reduces the number of BGP updates in large scale SP EVPN deployments. Apparently, some of them are working on IETF drafts to bring dataplane MAC learning “back” to EVPN. Not sure if this is really a relevant point - we know that BGP scales nicely, and its relatively easy to deploy virtualized RR with sufficient VPU resources.

While he’s absolutely correct that BGP scales nicely, the questions to ask is “what is the optimal way to deliver a Carrier Ethernet service?”

On the ‘net: Network Models at Packet Pushers

I’ve just started a new series on network models over at Packet Pushers. The first two installments are here:

I learned the Open Systems Interconnect (OSI) model way back in the mid-1980s, as a part of my basic networking education. Ever since then, I’ve used the OSI model in my day-to-day work as a network engineer.

First, models are not sacrosanct. A model is just a tool. If the model you are using is not working for you, feel free to modify it.

On the ‘Net: The IETF at Packet Pushers

I’ve been writing a series about working within the IETF to publish a new standard over at Packet Pushers. The most recent installments are:

There are other seemingly mystical concepts in the IETF process as well—for instance, what is a “document stream,” and what is a document’s “status?”

You’re almost ready to submit a shiny new document to the IETF for consideration, right? Not quite yet—we still need to deal with mandatory sections and language.
