Fujitsu flasher pleases data-intensive divas – SPC-1 benchmark

Cheap storage array IOPS and lots of them


If you need cheap storage array IOPS and lots of them, Fujitsu's DX600 S3 array can deliver those goods – at least according to an SPC-1 benchmark.

The Storage Performance Council (SPC) is an industry group dedicated to producing objective and vendor-neutral benchmarks to enable meaningful performance comparisons to be made between arrays. Its SPC-1 test simulates business-critical applications processing many complex transactions.

According to the tests, Fujitsu's ETERNUS DX600 S3 array trounced mid-range array competition in the sheer IOPS stakes, recording 320,206.35, and coming second to a 3PAR 7400 with its $1.54/IOPS cost - based on list pricing. The HP number was $0.58, though the difference might well be lost once street and/or bid pricing gets to work.

The DX600 S3 was fitted with 18TB of flash, that's 45 x 400GB MLC SSDs, and you can check out the config details here. We stuck them in a spreadsheet along with others and graphed 'em:

Mid_range_SPC_1_IOPS

What this chart doesn't show is that the average response time of the DX600 S3 at 100 per cent load was 0.61 millisecs. The 3PAR 7400's equivalent number was 0.86 – the DX600 S3 is fast.

Interestingly, although the DX600 S3 came eleventh in the overall SPC-1 rankings, it was number 1 in average response time at the 100 per cent load level – being the fastest-ever responding box in the SPC-1 lists we maintain.

Here is the cost/IOPS chart:

Mid-range storage array SPC-1 $/IOPS

The "net net" of the result is that all-flash systems fly on SPC-1 benchmark runs and disk-based systems haven't a prayer of competing in the IOPS and $/IOPS comparisons.

The DX600 S3 can support a mix of disks and SSDs, so Fujitsu classes it as a hybrid array. Get the all-flash version if you want a mid-range storage racehorse. ®

  • Robotics and 5G to spur growth of SoC industry – report
    Big OEMs hogging production and COVID causing supply issues

    The system-on-chip (SoC) side of the semiconductor industry is poised for growth between now and 2026, when it's predicted to be worth $6.85 billion, according to an analyst's report. 

    Chances are good that there's an SoC-powered device within arm's reach of you: the tiny integrated circuits contain everything needed for a basic computer, leading to their proliferation in mobile, IoT and smart devices. 

    The report predicting the growth comes from advisory biz Technavio, which looked at a long list of companies in the SoC market. Vendors it analyzed include Apple, Broadcom, Intel, Nvidia, TSMC, Toshiba, and more. The company predicts that much of the growth between now and 2026 will stem primarily from robotics and 5G.

  • Deepfake attacks can easily trick live facial recognition systems online
    Plus: Next PyTorch release will support Apple GPUs so devs can train neural networks on their own laptops

    In brief Miscreants can easily steal someone else's identity by tricking live facial recognition software using deepfakes, according to a new report.

    Sensity AI, a startup focused on tackling identity fraud, carried out a series of pretend attacks. Engineers scanned the image of someone from an ID card, and mapped their likeness onto another person's face. Sensity then tested whether they could breach live facial recognition systems by tricking them into believing the pretend attacker is a real user.

    So-called "liveness tests" try to authenticate identities in real-time, relying on images or video streams from cameras like face recognition used to unlock mobile phones, for example. Nine out of ten vendors failed Sensity's live deepfake attacks.

    How? Founder tells The Register 'Robots… lots of robots'

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."
