Video: Bridging Beyond Spanning Tree

In this week’s update of the Data Center Infrastructure for Networking Engineers webinar we talked about VLANs, VRFs, and modern data center fabrics.

Those videos are available with Standard or Expert ipSpace.net Subscription; if you’re still sitting on the fence, you might want to watch the how networks really work version of the same topic that’s available with Free Subscription – it describes the principles-of-operation of bridging fabrics that don’t use STP (TRILL, SPBM, VXLAN, EVPN)

Dell launches mini HCI system for Azure Stack

Dell Technologies has aggressively promoted Azure Stack, Microsoft’s software package that allows enterprises to run a complete copy of the Azure cloud service within their own data center.Now it has introduced a  hyperconverged infrastructure (HCI) system designed to support Azure Stack: a 1U server that allows organizations to start small with their deployment and grow.Formally known as Dell Integrated System for Microsoft Azure Stack HCI, the single-node system is designed for customers with smaller data-center footprints, but is expandable to support AI/ML workloads.To read this article in full, please click here

EVPN VLAN-Aware Bundle Service

In the EVPN/MPLS Bridging Forwarding Model blog post I mentioned numerous services defined in RFC 7432. That blog post focused on VLAN-Based Service Interface that mirrors the Carrier Ethernet VLAN mode.

RFC 7432 defines two other VLAN services that can be used to implement Carrier Ethernet services:

  • Port-based service – whatever is received on the ingress port is sent to the egress port(s)
  • VLAN bundle service – multiple VLANs sharing the same bridging table, effectively emulating single outer VLAN in Q-in-Q bridging.

And then there’s the VLAN-Aware Bundle Service, where a bunch of VLANs share the same MPLS pseudowires while having separate bridging tables.

Google launches VMs powered by newest Intel Xeon

Google Cloud announced new virtual machines as part of its cloud platform based on Intel’s newest Xeon Scalable processors.In addition to the new C3 virtual machine series, Google also announced it is deploying Infrastructure Processing Units (IPU), which are designed to intelligently route network traffic and take the load of network data processing off the CPU. The  company made the announcements at its Google Cloud Next ’22 conference held virtually.The IPU chip, formally known as the E2000, was co-designed by Google and Intel together and features 16 Arm Neoverse cores and 200GbE networking.C3 machine instances deliver performance gains of up to 20% over previous generation of C2 instances. They also benefit from a recent product launch called Hyperdisk, a block storage system that offers 80% higher IOPS per vCPU for data analytics and DBMS workloads when compared to other hyperscalers,To read this article in full, please click here

Hedge 150: Micah Beck and Universal Broadband

What would the Internet look like—or what kinds of services would need to be developed and deployed—to make boradband class service available to every user? What could this kind of development do to drive entire societies forward? Micah Beck, from the University of Tennessee, joins Tom Ammon and Russ White to discuss universal broadband on this episode of the Hedge.
