HDS kicks flash array baby out of pram

HFS A-Series given pink slip, told to walk the plank

We’re hearing HDS is retiring or downgrading its 11-month-old HFS A-Series all-flash array.

We understand this 60 x 2.5-inch slotter is an OEM’d version of a Raid Inc. box which has 30 side-mounted drives either side of a 2U tray. There are six rows of five stacked SSDs per side. Nimbus Data also uses the hardware in its ExaFlash B-Series, we believe.

The entry-level A220, costing $125,00 at street pricing, had a 16TB raw capacity rating, with the high-end 270 having 96TB.

The HFS array has a unique operating system, HFS Software, which HDS uses 2D (2bits/cell) MLC NAND SSDs in the A-Series with 1.6TB capacity. There are larger capacity TLC (3bits/cell) SSDs available, with capacities as high as 15.36TB (Samsung PM1633a).

When it was announced, the A-Series had a quarter-by-quarter roadmap for 2016, featuring replication between it and VSP arrays in the third quarter, and scale-out support in the current quarter.

Storage consultant Chris Evans said he thought that the A-Series lacked automated management, needed a scale-out capability and was a candidate for TLC drives.

The HDS US website has no good HFS A-Series info, although a PDF infographic mentions it. Ditto the Hitachi Japan site. It’s as if the A-Series has just vanished.


HDS HFS A Series all-flash array.

A channel source told us that HDS is concentrating on its all-flash VSP F-Series, an enterprise rack-level product introduced in October. It uses Hitachi’s proprietary flash modules and having a 100 per cent availability guarantee. This system runs the SVOS operating system and the entry-level F400 starts at a 14.4TB minimum capacity, rising to 256TB. Its starting (list) price is $218,200, way more than the HFS A220.

We asked HDS about this and were pointed to a blog by Nathan Moffitt, HDS' Director for Infrastructure Marketing. In it he says:

With SVOS 7 and our FMDs we are able to deduplicate and compress data, delivering capacity savings that match what every AFA product can deliver. Add in our FMDs and quality of service (QoS) technology and we can offer these savings while enabling more predictable performance than competitors. The end result is that we’ve created a power house that makes the HFS A series, unnecessary.

Moffitt explains: "Our original objective with the HFS A series was to deliver an entry, all-flash array that could serve as a “starter platform” for transitioning to an all-flash data center. It offered deduplication and QoS functions critical for the entry segment of the all-flash array market.

"This was great, but 2 things became apparent with the release of SVOS 7. First, we could meet the objectives (and price points) of HFS A series with VSP F series. Two, customers that were considering HFS A series wanted a roadmap that looked nearly identical to what we are already shipping on VSP F series!"

So "we’ve made the decision to announce the end of sales for the HFS A series."


Moffitt's message is that you can't make an omelette without breaking eggs. True 'dat, but here we see HDS doing more than breaking eggs. It's throwing away a misplanned omelette. ®

  • 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.

  • NASA's Psyche mission: 2022 launch is off after software arrives late
    Launch window slides into 2023 or 2024 for asteroid-probing project

    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.
