Huawei: Half a million IOPS? Pah, we can do better

SPC-1 speedster now fastest ever all-flash array


Huawei has captured the SPC-1 crown for disk drive and flash arrays with a 600,000-plus IOPS result for its Dorado5100 all-flash array.

The SPC-1 benchmark tests how networked storage arrays serve data requests from servers in a business environment. IBM's StorWize V7000 headed up the SPC-1 charts with a 520,043.99 result scored in January this year: the first time a system had breached the half-million IOPS level. Its average response time was 7.39ms and the cost/IOPS was $6.92. Its total system cost was $3,598,956.00 at list price.

Kaminario topped a million IOPS a few weeks ago but that was with an all-DRAM system, so it doesn't really count unless you need stratospheric performance. Back in the real world Huawei's OceanSpace Dorado5100 array achieved 600,052.40 SPC-1 IOPS with an average response time of 1.09ms and a cost/IOPS of $0.81. The total system list price cost was $488,617.00, meaning that an all-flash system which cost less that half a million dollars was faster overall and faster to respond than a $3.6m IBM storage array based on disks.

Now that IBM has bought TMS, which also features in the SPC-1 lists, as the chart shows, we can expect IBM results to perk up.

The Dorado5100 used mirrored flash, with a raw capacity of 19.2TB, and addressable capacity of 6.44TB. It had four flash enclosures, each with 24 x 200GB SSDs and a controller. Altogether there were two active-active controllers.

Huawei, IBM and TMS are regulars in the SPC-1 benchmark tests, each over-taking the others in turn. Will IBM and TMS, now one organisation, find a chink in Huawei's armour and overtake it again?

A stray thought: with more suppliers – and mainstream suppliers at that – entering the all-flash array product space, how long must we wait for Gartner to produce an all-flash array Magic Quadrant diagram? Won't that be fun to look at? ®

  • How ICE became a $2.8b domestic surveillance agency
    Your US tax dollars at work

    The US Immigration and Customs Enforcement (ICE) agency has spent about $2.8 billion over the past 14 years on a massive surveillance "dragnet" that uses big data and facial-recognition technology to secretly spy on most Americans, according to a report from Georgetown Law's Center on Privacy and Technology.

    The research took two years and included "hundreds" of Freedom of Information Act requests, along with reviews of ICE's contracting and procurement records. It details how ICE surveillance spending jumped from about $71 million annually in 2008 to about $388 million per year as of 2021. The network it has purchased with this $2.8 billion means that "ICE now operates as a domestic surveillance agency" and its methods cross "legal and ethical lines," the report concludes.

    ICE did not respond to The Register's request for comment.

  • Fully automated AI networks less than 5 years away, reckons Juniper CEO
    You robot kids, get off my LAN

    AI will completely automate the network within five years, Juniper CEO Rami Rahim boasted during the company’s Global Summit this week.

    “I truly believe that just as there is this need today for a self-driving automobile, the future is around a self-driving network where humans literally have to do nothing,” he said. “It's probably weird for people to hear the CEO of a networking company say that… but that's exactly what we should be wishing for.”

    Rahim believes AI-driven automation is the latest phase in computer networking’s evolution, which began with the rise of TCP/IP and the internet, was accelerated by faster and more efficient silicon, and then made manageable by advances in software.

  • Pictured: Sagittarius A*, the supermassive black hole at the center of the Milky Way
    We speak to scientists involved in historic first snap – and no, this isn't the M87*

    Astronomers have captured a clear image of the gigantic supermassive black hole at the center of our galaxy for the first time.

    Sagittarius A*, or Sgr A* for short, is 27,000 light-years from Earth. Scientists knew for a while there was a mysterious object in the constellation of Sagittarius emitting strong radio waves, though it wasn't really discovered until the 1970s. Although astronomers managed to characterize some of the object's properties, experts weren't quite sure what exactly they were looking at.

    Years later, in 2020, the Nobel Prize in physics was awarded to a pair of scientists, who mathematically proved the object must be a supermassive black hole. Now, their work has been experimentally verified in the form of the first-ever snap of Sgr A*, captured by more than 300 researchers working across 80 institutions in the Event Horizon Telescope Collaboration.

  • Shopping for malware: $260 gets you a password stealer. $90 for a crypto-miner...
    We take a look at low, low subscription prices – not that we want to give anyone any ideas

    A Tor-hidden website dubbed the Eternity Project is offering a toolkit of malware, including ransomware, worms, and – coming soon – distributed denial-of-service programs, at low prices.

    According to researchers at cyber-intelligence outfit Cyble, the Eternity site's operators also have a channel on Telegram, where they provide videos detailing features and functions of the Windows malware. Once bought, it's up to the buyer how victims' computers are infected; we'll leave that to your imagination.

    The Telegram channel has about 500 subscribers, Team Cyble documented this week. Once someone decides to purchase of one or more of Eternity's malware components, they have the option to customize the final binary executable for whatever crimes they want to commit.

  • Ukrainian crook jailed in US for selling thousands of stolen login credentials
    Touting info on 6,700 compromised systems will get you four years behind bars

    A Ukrainian man has been sentenced to four years in a US federal prison for selling on a dark-web marketplace stolen login credentials for more than 6,700 compromised servers.

    Glib Oleksandr Ivanov-Tolpintsev, 28, was arrested by Polish authorities in Korczowa, Poland, on October 3, 2020, and extradited to America. He pleaded guilty on February 22, and was sentenced on Thursday in a Florida federal district court. The court also ordered Ivanov-Tolpintsev, of Chernivtsi, Ukraine, to forfeit his ill-gotten gains of $82,648 from the credential theft scheme.

    The prosecution's documents [PDF] detail an unnamed, dark-web marketplace on which usernames and passwords along with personal data, including more than 330,000 dates of birth and social security numbers belonging to US residents, were bought and sold illegally.
