Blade Chassis to End of Row Swithces Connectivity & High Availability Options

Spanning Tree Protocol (STP) free network inside Data Centre is main focus for network vendors and many technologies have been introduced in recent past to resolve STP issues in data centre and ensure optimal link utilization. Advent of switching modules inside blade enclosures coupled with the requirements for optimal link utilization starting right from blade server has made today’s Data Centre network more complex.

In this blog , we will discuss how traditional model of network switches placement (End of Row) can be coupled with blade chassis with different options available for end to end connectivity / high availability.

Network Switches are placed in End of Row and in order to remove STP Multi-Chassis Link Aggregation (MC-LAG) is deployed. Please see one of my earlier blog for understanding of MC-LAG.

Option 1: Rack mounted servers for computing machines, servers have installed multiple NICs in Pass-Though module and Virtual Machines hosted inside servers require Active/Active NIC Teaming.

Option 2 : Blade Chassis has multiple blade servers and each blade servers has more than 1 NIC (which are connected with blade chassis switches through internal fabric link). Virtul Machines hosted inside blade servers require active/active NIC teaming.

The time travel paradox of artificial intelligence

Kurt Vonnegut’s novel Slaughterhouse Five and J.K.Rowling’s series of Harry Potter novels describe the time travel paradox. Traveling through time changes the future from the point in time where the traveler arrived. The personal assistant that will arrive at some time in the future will change humans from that point in time forward, but in a more impactful way than GPS.Artificially intelligent personal assistants will be part of our lives Google and Facebook have recruited the best artificial intelligence (AI) and machine learning talent in the world to build personal assistants in small increments.To read this article in full or to leave a comment, please click here

Docker Distributed System Summit videos & podcast episodes

Following LinuxCon Europe in Berlin last week, we organized a first of its kind Docker event called Docker Distributed Systems Summit. This two day event was an opportunity for core Docker engineers and Docker experts from the community to learn, collaborate, problem-solve and hack around the next generation of distributed systems in areas such as orchestration, networking, security and storage.

More specifically, the goal of the summit was to dive deep into Docker’s infrastructure plumbing tools and internals: SwarmKit, InfraKit, Hyperkit, Notary, libnetwork, IPVS, Raft, TUF and provide attendees with the working knowledge of how to leverage these tools while building their own systems.

We’re happy to share with you all the videos recordings, slides and audio files available as #dockercast episodes!

All the slides from the summit are available on the official Docker slideshare account.

Please join us in giving a big shout out to our awesome speakers for creating and presenting the following projects:

Worth Reading: Limitations of Current Branch Office WAN

A key characteristic of the traditional branch office WAN architecture is to have T1/E1-based access to a service provider’s MPLS network at each branch office and to have one or more high speed links at each data center. In this architecture it is common to backhaul some or all of a company’s Internet traffic to a data center before handing that traffic off to the Internet. In order to understand how common this architectural approach is, the survey respondents were asked to indicate how much of their Internet traffic that is generated in branch offices is backhauled to a data center before being handed off to the Internet. —ECI
