IEEE chaps propose QoS for SDN across the public internet

Software-defined networking (SDN) is fine in the data centre, but rubbish across multi-domain WANs, something a group of IEEE engineers wants to solve. Their proposal, on Arxiv, is to copy the cloud notions of abstraction and orchestration into Internet connections. Sucking nourishment out of the academic prose, the IEEE …

Microsoft gets storage QoS and software-defined storage religion

Microsoft is starting to make a lot of noise about software-defined storage and the need for storage quality of service. The company's Cambridge UK lab has just released Microsoft Research Storage Toolkit, a tool said to enable “effective and accessible research in Software Defined Storage by adding I/O classification functions …

Accedian goes hybrid NFV in carrier QoS product

Rather than pull out all the stops on network function virtualisation (NFV), telcos would like to stage their implementations one piece at a time, according to Canadian vendor Accedian Networks. That's the rationale behind the approach the company announced late last week, in which it wants to offer an enterprise-to-data-centre …

Pivot3 pivots, buys NexGen

Analysis In a major pivot, all-flash and hybrid array startup NexGen is merging with hyper-converged infrastructure appliance software startup Pivot3 in a cash-free stock merger. When startups merge that’s generally a sign that the original mission is failing and/or the backing VCS are getting nervous. What makes this more surprising …

Flash and trash? You could begin with cache and trash

Comment Last year I wrote many times about object storage, flash memory, caching, and various other technologies in the storage industry. And I also coined the term “Flash and Trash” (see video here) to describe a trend of two-tier storage built on latency-sensitive, flash-based arrays on one side and capacity-driven, scale-out systems …

Sprint sprints away from no-throttle policy – punishes 'unlimited' network hoggers

Sprint has confirmed plans to once again throttle data usage of customers who go over a 23GB limit each month. The company, which is the fourth largest mobile carrier in the US with nearly 58 million subscribers on its books, said that it was "unfair" to allow such behaviour to continue unchallenged, given that 97 per cent of …

Flash is fallible. But you'd rather have an AFA than spinning rust

We tend to think of flash as a solid-state disk – like spinning rust, only more expensive, consuming less power, and much, much faster. And yes, it is true that you can use it like that, but there is a lot more that flash can offer if you start to take into consideration what makes flash different in the first place. Simply …
