David F. Carr atInformation Weekcovers the keynote panel at Interop and their conversation regarding the future of SDN and network admin.
The point of SDN is to make networks easy to configure and reconfigure in software rather than hardware, with many more networking functions migrating from being embedded capabilities of a network appliance to being defined in software. Network systems are migrating incrementally in that direction as networks follow the same path toward virtualization as servers and storage, he said. Ultimately, the goal is to provide every data center with the flexibility associated with cloud computing.
Mellanox is speeding up VXLAN with an innovative hardware solution that enables large-scale cloud infrastructures.
To meet the growing demand of cloud computing services, cloud providers must be able to take full advantage of new software techniques to scale-up their cloud networks without reducing performance or efficiency of the infrastructure,” said Gilad Shainer, vice president of marketing at Mellanox Technologies. “With ConnectX-3 Pro, cloud providers will be able to easily scale and grow their business and provide new value-add services while reducing the cost of their cloud infrastructure; ushering in the age of Cloud 2.0
In this video, Mellanox CEO Eyal Waldman presents: Welcome to the Generation of Open Ethernet.
Open” is the keyword for today’s world of cloud computing and Web 2.0 applications. Open Ethernet, a new initiative led by Mellanox, will enable a new era of open data centers. It will give IT managers complete control of their networks to achieve better performance and lower costs. It will sweep away proprietary stacks, proprietary routing methods, and proprietary management software. Open Ethernet will expand open source into the data center to allow vendors and users to design the networks they want at costs they can afford. Open Ethernet means open code, access to open source management software, support for standard OpenFlow controllers, and much more. It will allow data centers to use commodity hardware and open source software to build the powerful switches, routers, and appliances they need for their purposes.
Depending on the application of the user’s system, it may be necessary to modify the default configuration of the network adapters and the system/chipset configuration. This slide deck describes common tuning parameters, settings & procedures that can improve performance of the network adapter. Different Server & NIC vendors may have different recommendations for the values to be set – but the general tuning approach should be similar. For the hands-on demo we will utilize Mellanox ConnectX adapters – thus we will implement the recommended settings issued by Mellanox.
Over at the Energy Sciences Network, Jon Bashor writes that ESnet’s FasterData.es.net is popular online repository of tips and tricks for improving network performance. Maintained by Brian Tierney for the last 15 years or so, the site comprises around 120 pages, about 50% of the page views where on the pages of that focus on tuning Linux hosts for better network performance on network paths above 1 gigabit per second.
There are a few settings that aren’t defaults and if you use them, they can gain you a lot in terms of performance,” said Tierney, cautioning that the same settings will actually downgrade the performance of slower networks or home routers. “The site contains a lot of arcane details that are hard to memorize, so users can go to a page, copy and paste the settings into their systems.”
The OFA User Workshop, April 18-19, provides opportunities to share experiences and learn from a community of OFS users.
The International Developer’s Workshop, April 21-24, will focus on the development and improvement of OFS as well as major developments in RDMA, etc. Agenda and more information is available on OpenFabrics.org.
Registration for the two events is now open. More details are available in this month’s OFA Newsletter, which features an interview with Susan Coulter, HPC Network Administrator at Los Alamos National Laboratory.
Over at the Emulex Blog, Sonny Singh writes that increasing complexity of data center environments and growth in storage have led to significant concerns about silent data corruption.
But really what it comes down to is without end-to-end protection technology, data corruption can go unnoticed until recovery is difficult and costly or even impossible to perform. Furthermore, without end-to-end integrity checking, these silent data corruptions can lead to unexpected and unexplained problems.
