Announcing the Network Break podcast – a regular look at the news in networking and cloud infrastructure in less than 30 minutes.
Big Switch Networks (BSN) launches Version 4.0 of Big Cloud Fabric for hardware-centric SDN data centre fabric. The Data Centre Fabric solution clearly shows the maturity gained from 5 years of shipping products while adding innovation in switch hardware through Switch Light operating system. At the same time, they have completed the transition from platform to product. A product that really has what you need in a hardware-centric SDN platform and addresses nearly all of the issues the competitors have not addressed. And it is shipping now.
Here is a block diagram showing the functional areas in private & public cloud that I use when working with clients. I’m often explaining the full picture of cloud building especially in relation to how the network can be orchestrated to fully accelerate the cloud process. I hope you find it useful.
The future of private infrastructure ownership is moving to a new model combines the old with the new that I describe as “dolls and babies” where the major transformation in infrastructure ownership is the transition from having babies to owning dolls. Infrastructure as Babies Enterprises buy infrastructure like people have babies. It takes months to […]
Lede: In discussions with a stealthy networking startup today, we were discussing how their overlay network technology for the SDN WAN was able to to detect network blackouts and brownouts in the physical network. Their answer was to run Bi-directional Forwarding Detection (BFD) in the overlay tunnels. Now you have effective quality and service detection in the overlay network.
Can the Internet be the “Cloud Network” ? If so, when could the transition happen (if it hasn’t started already) ?
Supposition/Hypothesis As a technology, the Internet has strikingly similar properties to sharing Compute and Storage as ‘Cloud’. A large pool of resource that can be used or shared between many parties. The total pool of resource is dynamically allocated. Internet bandwidth is shared between all users and access is determined by bandwidth purchased at the network edge
I’ve unearthed and updated a guide to creating network diagrams in Visio. I wrote the first versions in 2010 using a custom software and finally worked out how to export the data. If you ever wanted to
I doubt that anyone bought a Vblock because it was a market leading networking strategy. I’ve been a supporter of VCE but today I’m doubtful that choosing Cisco ACI is good strategy for their customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a services package of fully supported storage, compute and networking that removes customer risk around VMware deployments while reselling EMC & Cisco hardware.
TL:DR A recent project bought a low cost network for the data centre. It cost less one-third of the the market leader & half the cost of a well known merchant silicon vendors. As a result, it is planned to last for two, maybe three years before it will be replaced. From this project I learned that “fast & cheap networking” could make a big impact on new data centre designs and business attitudes. Plus it was much more satisfying as a professional project. I’m now wondering – is networking too expensive ?
Recently, Dave at DavesBlog made some rather startling observations that Verizon is throttling Netflix traffic, backed up by a comment from some low level help desk staffer that this is true. The technical capability of a person who performs front line technical support is usually set at a low level to match what most customers need. Taking a casual comment as “truth” is wildly unreasonable. Here is more on the reality of net neutrality.
