Before I present this episode’s collection of links, articles, and thoughts on various data center technologies, allow me to first wish all of my readers a very merry and very festive holiday season. Mustafa Akin has an article on Docker’s new overlay networking functionality. Servers/Hardware. Now, on to the content!

Using 1 GbE would have required too many ports, too many cables, and too many switches; 10 GbE offered Expedient a 23% reduction in cables and ports, a 14% reduction in infrastructure costs, and offered a significant bandwidth improvement (compared to the previous 1 GbE architecture).

Welcome to Technology Short Take #25, my irregularly-published collection of links, articles, thoughts, and rants. Servers/Hardware. This is an awesome overview of the OpenStack Folsom architecture , courtesy of Ken Pepple. This article was originally posted on blog.scottlowe.org. my apologies for that. Virtualization.

According to Martin, the term SDN originally referred to a change in the network architecture to include a) decoupling the distribution model of the control plane from the data plane; and b) generalized rather than fixed function forwarding hardware. What about virtualized load balancers? What about NX-OS, JUNOS, or EOS?

Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). Recep talks about how the predominant architecture for network virtualization involves the use of overlay networks created and managed at the edge by virtual switches in the hypervisors. So how does this work?

Whether it is redundant hardware or a private hot-site, keeping an environment up and running 99.99% (insert more 9’s here) of the time is a tough job. With a well-planned deployment, and a good infrastructure, companies can efficiently load-balance their IT environment between multiple active, cloud-based, sites.

Once again this comes back to Intel’s rack-scale architecture work.) A traditional SRF architecture can be replicated with COTS hardware using multi-queue NICs and multi-core/multi-socket CPUs. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB). Gbps/watt versus 0.37

First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Not unsurprisingly, one of the key advantages of STT that’s highlighted is its improved performance due to TSO support in NIC hardware. Servers/Hardware. I needed to fill in some other knowledge gaps first.)

A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc.
