Collection of useful, relevant or just fun places on the Internets for 31st July 2013 and a bit commentary about what I’ve found interesting about them:
Ethernet Is the Right Way to Network Microserver Clusters – Thought provoking article from intel that discusses using Ethernet on microserver motherboard as a way of connecting servers. Although Cisco does this already in the UCS, the microserver approach would be signficantly different and mainstream.
Ethernet never seems to stop evolving to meet the needs of the computing world. First it was a shared medium, then computers need more bandwidth and multi-port bridges became switches. Over time, Ethernet speeds increased by four orders of magnitude. The protocol was updated for the telecom network, then for data centers.
IETF 87 Meeting Agenda – IETF 87 Session Agenda. Lots of great content about the happenings in the IETF. I’m downloading a number of PDF files for reading.
Cisco onePK: Now I Get It | packetmischief.ca – Joel Knight talks about his understanding of how onePK will impact his network and operations. Really good article on the journey from CLI to API.
The geek in me is pretty excited by onePK. Having the ability to program the network is going to open up a whole new set of possibilities. I’m no stranger to hacking code to automate tasks in the network or pull telemetry from the network. But, I’ve always been relegated to SNMP or scraping the output from the CLI. Being able to write software against a standard API is really exciting! No more modifying the script to understand different OS versions/families or dealing with parsing CLI prompts
Intel’s Data Center Plan: More Than Chips – Network Computing – Kurt Marko has a very good article on Intel and how it plans to change the data centre of the future. I’m particulary interested in ti idea of pools of CPU and memory that can be dynamically pooled (and suspect that this is what Insieme is doing).
Waxman said future generations of rack-scale systems will use the optical network backplane to connect pools of compute, memory (i.e. high-speed system memory shared among compute nodes) and storage chassis within a single rack. Dahlen said the goal of integrated fabrics is to eliminate network bottlenecks between high-density servers while reducing the number of cables in a rack by a factor of three.
The OpenFlow Overlay | NetworkStatic | Brent Salisbury’s Blog – Brent Salisbury talks about technical details of using OpenFlow to build an Overlay Network.
Former Nicira VP Alan Cohen Joins Stealthy Security Startup Illumio – Arik Hesseldahl – News – AllThingsD – This is an interesting development and confirms my view that Security is ripe for disruption. Note: A startup is not very stealthy when you are on the front page of All Things D website. A failure of OpSec perhaps 🙂
Alan Cohen, one of the early executives of the software-defined networking company Nicira, has joined the stealthy security startup Illumio.
Mac App Store – JPEGmini Lite – Dramatically reduces the size of JPEG files. This is the free version (crippleware to 20 iages per day). If you run a blog you should have this software.
Mac App Store – Progressive Downloader – I need a Download Manager because I have limited Internet bandwidth but they are useful for many tasks. Since Speed Download seems to be end of life it is time to look for more software.
Progressive Downloader is a powerful and flexible download manager.
Pinterest adds personalization features based on your web-browsing history — Tech News and Analysis – This GigaOm article about about The Pinterest buttons on ANY website will be used to profile your web activities EVEN if you don’t have an account. Justification: they want the data just in case in you ever sign up they can give you a better experience.
The new personalization feature mean that if you visit a site that has the “Pin It” button installed (which is nearly every major U.S. retailer, from Target to Amazon), and then you go to Pinterest, the social media site will be able to make suggestions for content based on what you’ve browsed on those other sites.
That’s Facebook creepy ( who do the same thing ).
Software-Defined Networking: SR-IOV: A Tr… | Brocade Communities – I thought this was a very good simple outline of what SR-IOV is. I still don’t feel I have a complete grasp of the technology but I have a better idea of why I should learn about it.
These layers generally consists of the hypervisor’s virtual switches, system level drivers, hypervisor OS drivers, and so on. I/O techniques such as Peripheral Component Interconnect passthrough (PCI passthrough) and Single-Root I/O Virtualization (SR-IOV) are ways to bypass these components and tie the NIC directly to the interfaces of the virtual machine for higher throughput and performance.
