Network codes designed specifically for distributed storage systems have the potential to provide dramatically higher storage efficiency for the same availability. One main challenge in the design of such codes is the exact repair problem: if a node storing encoded information fails, in order to maintain the same level of reliability we need to create encoded information at a new node. One of the main open problems in this emerging area has been the design of simple coding schemes that allow exact and low cost repair of failed nodes and have high data rates. In particular, all prior known explicit constructions have data rates bounded by 1/2. In this paper we introduce the first family of distributed storage codes that have simple look-up repair and can achieve rates up to 2/3. Our constructions are very simple to implement and perform exact repair by simple XORing of packets. We experimentally evaluate the proposed codes in a realistic cloud storage simulator and show significant benefits in both performance and reliability compared to replication and standard Reed-Solomon codes. © 2012 IEEE.

Nowadays Decision is a matter of information (related to the data), knowledge (related to people & processes) and timing (capacity to decide, act and react in the right timing). The huge increase of the data volume, velocity but also format (unstructured data like: blogs, logs, video…) generated by the “digitalization” of our world modifies radically our relationship to the space (in motion) and time (all the time) dimension and by capillarity, the enterprise vision of the performances monitoring and optimization. This paper introduces via three use cases, how the closed loop between Big Data & Smart Data embedded into the business processes can help the enterprises facing this new challenge. © Springer International Publishing Switzerland 2014.

NEW YORK---Rock band U2 were dozens of USB flash drives and a stolen backpack away from being screwed in 2011. Now, U2 is packing a flash storage array designed for small businesses, and a decent amount of abuse. U2 is winding up its first leg of its North America iNNOCENCE + eXPERIENCE Tour 2015 with eight shows at Madison Square Garden. The shows are creating multiple terabytes of video and archive material that used to be delivered on USB drives. Now U2 has traded up to EMC's VNXe3200, an all flash array that will run about $25,000 and is typically designed for smaller enterprises. The VNXe3200 can store up to 450TB of data. For U2's increasingly video-heavy tour---the band has a massive screen that has current footage, archive material, animations and a walkway for band members to walk through, play in, and create special effects---there's a need to store and call up data on the fly. U2 has deployed 2 PRG Nocturne V-Thru LED Screens, each measuring 29m by 7m for the tour. EMC has coupled the VNXe3200 with its Data Domain backup technology. Christopher Ratcliffe, senior vice president of EMC's core technologies unit, said U2 called him while he was grocery shopping for tour help. Ratcliffe has worked on a few special events and knows Stefaan "Smasher" Desmedt, who runs video for U2 and other acts, through a partnership with LiveNation. The storage requirements for U2 roughly went like this: EMC's flash array is connected to Macs and PCs, and content is rendered on network attached storage. Most of the content is large and uncompressed. The kinks in the system were worked out in a 6 week tech run through, where an arena in an undisclosed location was rented for stage setup. From there, the band played for about four weeks to prep set lists. U2's business case for collecting data and archiving it is simple. The band makes little money on selling albums. In fact, U2 is likely to collect more from T-shirts than songs. Today, musicians make their money via tours and collecting video and other data that may be monetized at some point. "If there's a blue screen behind Bono someone is losing his job," quipped Ratcliffe. One notable point from U2's storage strategy is that there isn't a cloud plan yet. U2 needs on-premise storage due to latency. Information needs to be called up on the fly given the band may call an audible quickly. As U2 starts its European leg of its tour, Ratcliffe said EMC will likely add capacity to the storage system. Traditional disk will likely be added to keep costs down and hold data that doesn't need to be accessed quickly. There is also talk of a cloud option at some point for archiving.

After Fred Luddy founded ServiceNow in 2003, he was still a little shell-shocked from his experience as the CTO of San Diego’s Peregrine Systems. Luddy had spent 13 years developing Peregrine’s asset management product before the high-flying enterprise software giant collapsed in a corporate accounting scandal in 2002. When a new management team finally calculated the extent of the fraud as part of Peregrine’s bankruptcy reorganization, Luddy said his Peregrine fortune was “zero.” He estimated that his stake in the company had amounted to $35 million just a few years earlier, when he was 40. Now Luddy is 60, and he has a pretty good comeback story—which he told last week in a special presentation to the San Diego Venture Group. It was a relatively rare public appearance for Luddy, and was billed as “a fireside chat” with Paul Barber, the San Diego-based managing general partner of JMI Equity, the investment firm (and related entitites) that provided the initial $9.3 million in startup funding to ServiceNow. In the 13 years since Luddy started ServiceNow, the company has grown into a software industry juggernaut, with roughly 3,400 employees and a current market valuation of nearly $12 billion. At the time of ServiceNow’s initial public offering in 2012, Luddy owned a 9 percent stake in the company (about 13.4 million shares), and Forbes estimated his net worth at $400 million. ServiceNow’s software, like Peregrine’s, helps big companies and organizations manage their help desk and IT services. But where Peregrine installed its enterprise software on its customers’ internal networks, ServiceNow was among the software companies pioneering cloud-based, software-as-a-service. The company has expanded over time into more of a platform-as-a-service, and now provides Web-based software used by big organizations to manage their human resources, legal, and financial services. The company also enables customers to easily develop their own forms-based workflow applications. Much of that growth has occurred since 2011, when ServiceNow named ex-Data Domain CEO Frank Slootman to succeed Luddy as CEO—and Luddy shifted into a more familiar role as chief product officer. But Luddy said that making the transition was one of the most stressful periods of his life. Before Slootman joined the company, Luddy said he was initially unsure whether he should continue as CEO, or shift to a more familiar role in software development. He recalled that Sequoia Capital partner and ServiceNow board member Doug Leone took him on a tour of several Silicon Valley software companies, so he could meet CEOs and talk with them about their jobs. The process helped him realize that he didn’t have the kind of CEO skills that ServiceNow needed, “and I had no interest in acquiring them.” It may sound funny, Luddy told the audience, but “I wake up every morning, and all I want to do is write code.” Nevertheless, it was still hard to hand over control of the company to Slootman. “When Frank came in, we had some famous fights,” Luddy said. Yet he conceded that the corporate culture at ServiceNow “had to become Frank’s culture. Our culture was very collegial, but it wasn’t really a culture of excellence and execution.” Making that transition was a fractious and … Next Page » Bruce V.
