Upcoming Live Training: Data Center Fabrics

I’ve rebuilt my data center fabrics live training class, adding a lot of new material across the board, and adding a few new topics. To cover all this new material, the class has been expanded from three to six hours. I’m teaching it for the first time on the 29th and 30th of this month.

From the Safari Books description—

Data centers are the foundation of the cloud, whether private, public, on the edge, or in the center of the network. This training will focus on topologies and control planes, including scale, performance, and centralization. This training is important for network designers and operators who want to understand the elements of data center design that apply across all hardware and software types.

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 Continue reading

Hedge 146: Leslie Daigle and Unwanted Traffic in the DFZ

How much of the traffic on the Internet is wasted—traffic no-one really wanted, and yet is being carried and paid for by providers and end users? In a world increasingly concerned about the waste of precious resources, this is an important topic to consider. Leslie Daigle joins Russ White and Tom Ammon on this episode of the Hedge to discuss the kinds of traffic she’s seeing hit their large-scale honey-trap, and the implications for the Internet.

From Bits to Application Data

Long long time ago, Daniel Dib started an interesting Twitter discussion with this seemingly simple question:

How does a switch/router know from the bits it has received which layer each bit belongs to? Assume a switch received 01010101, how would it know which bits belong to the data link layer, which to the network layer and so on.

As is often the case, Peter Paluch provided an excellent answer in a Twitter thread, and allowed me to save it for posterity.

IBM is leasing on-prem System i servers

IBM has jumped on the consumption/leasing bandwagon by offering a low-cost subscription for its Power 10-based System i.For $50 per user per month, IBM will place a quad-core POWER S1014-based System i server on-premises. Extra licenses can be acquired in lots of five. Leases are for three to five years, and IBM service the machne either remotely or on-site. [ Get regularly scheduled insights by signing up for Network World newsletters. ] The specs are fairly modest but aimed at SMBs. The machine will come 64GB of memory, up to 6.4TB of NVMe storage, and both Ethernet and fiber channel connectivity. However, it may come with a quad-core processor, but just one core will be active.To read this article in full, please click here
