NetApp and Microsoft: We're 'close' to virtual ONTAP on Azure

Federated array across the cloud ... and your own bit barn


NetApp and Microsoft are close to delivering a working version of the former's storage operating system Data ONTAP as a virtual machine capable of running under Hyper-V, and therefore on Windows Azure.

Once some final issues are addressed, The Reg understands it will be possible to run a virtual NetApp array on Azure and maybe to federate it with on-premises NetApp arrays.

The seed for this approach was sown in May 2012, when Microsoft, Citrix and NetApp announced they would work together to make FreeBSD run as a guest OS under Hyper-V.

Data ONTAP is based on FreeBSD, but in mid-2012 virtual SANs were rather less interesting than they are today: NetApp's own ONTAP-v was a curiosity offered only in partnership with Fujitsu.

A lot has happened in the cloud since May 2012 and virtual SANs are now a serious challenge to many classes of array. NetApp itself suggests a virtual SAN is a fine idea for branch offices.

The company feels it is now close, according to a staffer familiar with the matter, to developing a virtual version of Data ONTAP capable of being deployed in either Hyper-V or Microsoft's Azure cloud. Drivers remain a hurdle to be overcome, but Microsoft and NetApp are working to solve the problem.

Once the virtual array emerges, it may become possible to operate it in the cloud and point it at Azure storage, or federate on-premise and cloud storage. A Microsoft-centric version of NetApp's Direct Connect deal with Amazon Web Services (AWS), which sees NetApp arrays live in AWS data centres to hasten data movements to and from the cloud, is also a prospect.

Bursting from on-premise workloads reliant on a physical array to a virtual cloudy array is another planned usage model. AWS won't be left out of that party.

Just when this will all emerge isn't known. Citrix, Microsoft and NetApp have been working on FreeBSD for nearly two years now, but Windows Server doesn't look like getting an update until 2015.

Would Redmond push out some extra Hyper-V drivers to give NetApp a leg-up before then? If it gives Microsoft a way to make Azure more attractive, and score some serious coin from long-term cloud storage customers, just maybe.

John Rollason, NetApp's EMEA director of products, solutions and alliances marketing told us: "[I c]an’t comment on specific future plans, but can say we are committed to working with leading service providers to take advantage of the value of our software, including ONTAP as a VSA. The really unique value for customers is the possibility to use Data ONTAP as the Universal Data Platform across a choice of hybrid of Private, Public and SP clouds." ®

    In brief Thieves operating for the North Korean government made off with almost $400m in digicash last year in a concerted attack to steal and launder as much currency as they could.

    A report from blockchain biz Chainalysis found that attackers were going after investment houses and currency exchanges in a bid to purloin funds and send them back to the Glorious Leader's coffers. They then use mixing software to make masses of micropayments to new wallets, before consolidating them all again into a new account and moving the funds.

    Bitcoin used to be a top target but Ether is now the most stolen currency, say the researchers, accounting for 58 per cent of the funds filched. Bitcoin accounted for just 20 per cent, a fall of more than 50 per cent since 2019 - although part of the reason might be that they are now so valuable people are taking more care with them.

    In brief California’s Department of Motor Vehicles said it’s “revisiting” its opinion of whether Tesla’s so-called Full Self-Driving feature needs more oversight after a series of videos demonstrate how the technology can be dangerous.

    “Recent software updates, videos showing dangerous use of that technology, open investigations by the National Highway Traffic Safety Administration, and the opinions of other experts in this space,” have made the DMV think twice about Tesla, according to a letter sent to California’s Senator Lena Gonzalez (D-Long Beach), chair of the Senate’s transportation committee, and first reported by the LA Times.

    Tesla isn’t required to report the number of crashes to California’s DMV unlike other self-driving car companies like Waymo or Cruise because it operates at lower levels of autonomy and requires human supervision. But that may change after videos like drivers having to take over to avoid accidentally swerving into pedestrians crossing the road or failing to detect a truck in the middle of the road continue circulating.

  • Alien life on Super-Earth can survive longer than us due to long-lasting protection from cosmic rays

    Laser experiments show their magnetic fields shielding their surfaces from radiation last longer

    Life on Super-Earths may have more time to develop and evolve, thanks to their long-lasting magnetic fields protecting them against harmful cosmic rays, according to new research published in Science.

    Space is a hazardous environment. Streams of charged particles traveling at very close to the speed of light, ejected from stars and distant galaxies, bombard planets. The intense radiation can strip atmospheres and cause oceans on planetary surfaces to dry up over time, leaving them arid and incapable of supporting habitable life. Cosmic rays, however, are deflected away from Earth, however, since it’s shielded by its magnetic field.

    Now, a team of researchers led by the Lawrence Livermore National Laboratory (LLNL) believe that Super-Earths - planets that are more massive than Earth but less than Neptune - may have magnetic fields too. Their defensive bubbles, in fact, are estimated to stay intact for longer than the one around Earth, meaning life on their surfaces will have more time to develop and survive.
