EMC eyeing XtremIO ... just a rumble on the jungle drums?

Or it might be the sound of back-end Thunder


Is EMC eyeing up flash array startup XtremIO, the one that's making extreme I/O claims about the all-flash array its developing?

El Reg heard a rumble from the storage jungle drums that this was so, but our source went deep into the bamboo as soon as we asked for more. So we asked ourselves why EMC should bother.

Let's start by pointing out that EMC has a scale-out filesystem/big data array in the shape of the peer-scaling, InfiniBand-using Isilon kit. Let's also note that EMC has added an SLC-based VFCache to its product armoury to get hot data as close as possible to individual servers.

This is getting enhancement in two ways. Firstly (according to EMC flash storage CTO Daniel Cobb, courtesy of a note from Piper Jaffray analyst Andrew Nowinski) by adding:

- automated vMotion
- deduplication
- policy-managed caching similar to the way FAST VP tiering software with automated data movement
- probable addition of cheaper but higher capacity MLC flash option

The next version of VFCache should see these features.

The second boost for hot data server-closeness is by adding a sharable flash array between the back-end storage arrays, such as VMAX, VNX, and Isilon, with its Thunder project connected to servers by a high-speed interconnect like InfiniBand.

The idea is that Thunder is fed data both by the front-end VFCache-enabled servers and the back-end arrays, and makes it sharable at high-speed between the servers with, maybe, FAST VP tiering data automatically between the back-end arrays, Thunder, and individual server VFCaches.

Let's remember this while casting our eye over XtremIO which is developing an all-flash array with these characteristics:

- combination of extreme performance, extreme efficiency, and an extremely strong business case
- scale-out with peer nodes
- high-availability enterprise storage array
- innovative architecture and storage algorithms
- simplifies provisioning
- a tremendous leap forward in I/O and latency performance to the market
- has unique new capabilities that hard drive-based storage cannot match
- eliminates the complexity that has traditionally plagued SAN storage configuration and tuning
- eliminates complex tuning procedures for a wide range of use cases

Deployed in a data centre, XtremIO's all-flash arrays will, it's claimed:

- dramatically improve performance
- accelerate applications
- support higher workloads at a competitive price to traditional disk arrays

The use cases include virtual server and virtual desktop infrastructure, database consolidation, analytics and business intelligence.

It's not hard to see the fit here is it? The XtremIO box could be Thunder spec-wise. Scale-out with peer nodes sounds almost like Isilon in flash. In fact we could see EMC eyeing up this great little startup and thinking Thunder could use its technology and so could Isilon. With XtremIO technology in its Thunder and Isilon products it could then provide a ginormously great platform for Greenplum analytics to run on. We could see EMC exec's saliva glands going into production overload over the prospects.

Of course this could be the demented imaginings of a bunch of pot-smoking Reg geeks. On the other hand…..

XtremIO is VC-funded to the tune of around $25 million. Assume a 5X premium and EMC would pay $125 million. It's a feasible deal wouldn't you think? ®

  • Will Lenovo ever think beyond hardware?
    Then again, why develop your own software à la HPE GreenLake when you can use someone else's?

    Analysis Lenovo fancies its TruScale anything-as-a-service (XaaS) platform as a more flexible competitor to HPE GreenLake or Dell Apex. Unlike its rivals, Lenovo doesn't believe it needs to mimic all aspects of the cloud to be successful.

    While subscription services are nothing new for Lenovo, the company only recently consolidated its offerings into a unified XaaS service called TruScale.

    On the surface TruScale ticks most of the XaaS boxes — cloud-like consumption model, subscription pricing — and it works just like you'd expect. Sign up for a certain amount of compute capacity and a short time later a rack full of pre-plumbed compute, storage, and network boxes are delivered to your place of choosing, whether that's a private datacenter, colo, or edge location.

  • Intel is running rings around AMD and Arm at the edge
    What will it take to loosen the x86 giant's edge stranglehold?

    Analysis Supermicro launched a wave of edge appliances using Intel's newly refreshed Xeon-D processors last week. The launch itself was nothing to write home about, but a thought occurred: with all the hype surrounding the outer reaches of computing that we call the edge, you'd think there would be more competition from chipmakers in this arena.

    So where are all the AMD and Arm-based edge appliances?

    A glance through the catalogs of the major OEMs – Dell, HPE, Lenovo, Inspur, Supermicro – returned plenty of results for AMD servers, but few, if any, validated for edge deployments. In fact, Supermicro was the only one of the five vendors that even offered an AMD-based edge appliance – which used an ageing Epyc processor. Hardly a great showing from AMD. Meanwhile, just one appliance from Inspur used an Arm-based chip from Nvidia.

    Sadly for NASA's mission to take samples from the asteroid Psyche, software problems mean the spacecraft is going to miss its 2022 launch window.

    The US space agency made the announcement on Friday: "Due to the late delivery of the spacecraft's flight software and testing equipment, NASA does not have sufficient time to complete the testing needed ahead of its remaining launch period this year, which ends on October 11."

    While it appears the software and testbeds are now working, there just isn't enough time to get everything done before a SpaceX Falcon Heavy sends the spacecraft to study a metallic-rich asteroid of the same name.

  • Rise in Taiwanese energy prices may hit global chip production
    National provider considering cost increase of 8%, which could be passed on to tech customers

    Taiwan's state-owned energy company is looking to raise prices for industrial users, a move likely to impact chipmakers such as TSMC, which may well have a knock-on effect on the semiconductor supply chain.

    According to Bloomberg, the Taiwan Power Company, which produces electricity for the island nation, has proposed increasing electricity costs by at least 8 percent for industrial users, the first increase in four years.

    The power company has itself been hit by the rising costs of fuel, including the imported coal and natural gas it uses to generate electricity. At the same time, the country is experiencing record demand for power because of increasing industrial requirements and because of high temperatures driving the use of air conditioning, as reported by the local Taipei Times.

  • Tech companies ready public stances on Roe v. Wade
    Some providing out-of-state medical expenses, others spout general pro-choice statements

    Several US tech companies have taken a stance or issued statements promising healthcare-related support for employees following the Supreme Court's ruling to overturn Roe v Wade last Friday.

    A Supreme Court draft opinion that was leaked in February provided advanced warning of the legal eventuality, giving companies plenty of time to prepare official positions and related policies for employees.

    Without proper policies in place, tech companies could put themselves at risk of "brain drain" as employees become tempted to relocate to states where abortion access is readily available or to companies that better support potential needs as healthcare in the US is more often tied to an employer than not.
