A 22 month observing campaign began in February 2017 and has so far detected over 50 lunar impact events (September 2018). The impact events are verified by an expert, characterized and made available to the scientific community and the general public via the NELIOTA website within 24 hours of discovery. We have also developed a software system, which controls both the telescope and the cameras, processes the images and automatically detects candidate NEO lunar impact flashes. The project has deployed a hardware system for recording and processing images. The twin imaging system includes a pair of identical sCMOS detectors providing simultaneous observations in two photometric bands at a rate of 30 frames-per-second. The 1.2 m Kryoneri telescope of the National Observatory of Athens was upgraded in 2016 and a prime focus, wide-field, high-speed, twin-camera Lunar imager was commissioned for this purpose. In a recently published report, "The Reality of the All Flash Datacenter," the firm estimated that, by 2020, 30 percent of all greenfield projects will adopt all-flash, and existing datacenters will follow, with all-flash accounting for 25 percent of all full storage refresh.NELIOTA (NEO Lunar Impacts and Optical TrAnsients) is an ESA-funded lunar monitoring project, which aims to determine the size-frequency distribution of small Near-Earth Objects (NEOs) via detection of impact flashes on the surface of the Moon. Market research firm Neuralytixs believes that the all-flash datacenter is gaining serious ground in enterprise and showing no signs of slowing. "That's what has the highest impact on their business. "People understand the value of the productivity of their engineers," Goldstein said. The ability to integrate production and non-production copies of the database offers productivity gains in the application development lifecycle that are driving the adoption of all-flash, Goldstein said. Because they'd all be on the same array, you could build a workflow around those copies with high performance." You could make instant copies of things that are on the array without consuming more space just by manipulating the metadata. But now here we were, designing an array that would be globally deduplicated. "Along with a production instance, they would have at least a handful of copies they were using to develop their application code and test it, to test patches before they went into production, and to provide separate copies for reporting. "Back when started thinking about how we would design the XtremIO array -we're talking 20 - customers typically had copies of the databases all over the place," Goldstein recalled. That architecture has allowed EMC to build a range of services into the XtremIO all-flash array, including a much-lauded capability called Integrated Copy Data Management (iCDM), which allows for the consolidation of primary data and copies on the same scale-out all-flash array. The performance is there, of course, but you can do a lot of things in an all-flash architecture that are not feasible in a disk or hybrid architecture." "We started with hybrid arrays many years ago, and correctly saw that all-flash was coming and going to be much more than just a performance play. "EMC got into the flash game very early," he told me. Josh Goldstein, VP of marketing and product Management in EMC's XtremIO business unit, credits "the execution piece" for his company's all-flash market dominance, but allows that timing was also a factor. XtremIO generated revenues of more than $1 billion for the year, the company says. According to IDC's recently published Quarterly Enterprise Storage System Tracker, the company snagged a 40.3% market share in Q4 2015, up 4.1% over the previous year. According to industry analysts at IDC, in 2015 EMC captured about the same market share as the next three competitors combined. ![]() EMC president of products and marketing, Jeremy Burton, declared 2016 "the year of all-flash."Īlmost certainly one of the things that has made EMC an attractive acquisition target is the sustained and rapid growth of its all-flash storage array, XtremIO, which was launched last year. A shareholder vote on the deal is set for July 19.īut last month's EMC World event in Las Vegas reflected some of that light onto the company's all-flash storage story. tech sector at an estimated $67 billion, though that estimate has fluctuated since the deal was first announced in October 2015, thanks largely to the volatile stock price of EMC's VMware organization. The acquisition will be one of the largest ever in the U.S. There's a big spotlight on Dell's pending acquisition of data storage giant EMC, and rightly so. ![]()
