Anyone fancy testing the 'unlimited' drive writes claim on Nimbus Data's 100TB whopper SSD?

Samsung, Toshiba sulking in 30TB tiddler territory


Nimbus Data has introduced its 100TB ExaDrive DC series SSD, the highest-capacity flash drive available.

It has some unusual characteristics but, first, let's show its size advantage by checking out the competition:

Intel, Micron and SK Hynix are basically nowhere in the very high-capacity SSD area.

Samsung talked about a 2.5-inch form factor 128TB flash drive in August last year, which would use QLC (4bits/cell) and 3D NAND technology implemented as a package of parallel accessed 32 stacked 1Tb chips.

Nimbus introduced a 50TB ExaDrive SSD in August last year, and Viking and SMART Modular Technology OEM'd it.

The 100TB ExaDrive has a 3.5-inch enclosure, a SATA interface, and is built from MLC (2bits/cell) 3D NAND. It has, Nimbus claims, the lowest power/TB rating, down to 0.1W/TB, 85 per cent lower than Micron's 5100 drive.

The random read/write IOPS performance is up to 100,000/100,000 – symmetrical – which is unusual as the majority if SSDs are skewed towards faster random read IOPS. The 100,000 level isn't "fast" as such; Toshiba's PM5 and Samsung's PM1643 do up to 400,000. This indicates that online transaction processing-type applications are not for this drive, which appears to be optimised for capacity and efficiency.

IDC Research VP Eric Burgener said: "Devices of this class will allow flash to cost-effectively penetrate a broader set of use cases outside of tier 0 and tier 1 applications."

The sequential read/write bandwidth is symmetrical too, being 500MB/sec, which seems low. The PM1643 does 2100/700MB/sec, while the PM5 offers up to 3,350/2,720MB/sec.

Savings offered by the ExaDrive over these drives are physical space and power. A theoretical 100PB constructed from 3,264 Samsung PM1643 SSDs would need 6 x 45U racks, according to Nimbus, and around 50kW of power.

The same ExaDrive-sourced capacity would need one rack, 990 drives and draw about 16kW. Nimbus suggests the ExaDrive DC 100 will cost cost 42 per cent less per terabyte over a five-year period than existing enterprise SSDs because of its greater endurance, lower power draw and other factors.

Nimbus's 100TB drive offers unlimited write endurance for its five-year warranty period, which contrasts with the 1 to 10 full drive writes per day from the SSDs listed above. The "Unlimited" rating is almost an invitation to try and break it by writing to the drive constantly and seeing how long it would last.

The ExaDrive also has a 2.5 million hours MTBF (mean time before failure) rating, capacitor-based power loss protection, several ECC engines, encryption and secure erase.

The company suggests tier 0/1 data should be stored on NVMe SSDs, tier 3 nearline data (archive, DR copies, backup, cold data) on disk, with the ExaDrive being for the tier 1 and 2 areas.

Deep Storage chief scientist Howard Marks suggests that hyperscalers might be the main customers for the ExaDrive DC 100, possibly with fast access archives in mind. He thinks you would need distributed parity across 50-100 drives to get an acceptable rebuild time for a failed drive. A RAID scheme with 10 drives might take a long time to rebuild if one dies.

The ExaDrive DC series will be available with both a 100TB and 50TB capacity. Both are being sampled with customers and should ship in the summer. Nimbus says pricing will be similar to existing enterprise SSDs on a per terabyte basis. ®

Copper load of this: Openreach outlines 77 new locations where it'll stop selling legacy phone and broadband products

You can't buy this kind of service. No, literally

BT-owned infrastructure provider Openreach has confirmed plans to stop sales of copper-based phone and broadband services in 77 exchange locations across the UK, affecting roughly 700,000 premises.

The “stop-sell” order will come into effect on April 29, 2022. Included in the 77 locations are Ellesmere Port in Cheshire, Hayes in Greater London, Kelso in Scotland, and Coleraine in Northern Ireland.

Those clinging to their legacy-based copper phone lines won’t necessarily see any immediate changes to service. However, the “stop sell” order means that anyone who switches broadband or landline providers will only be able to choose from products delivered over fibre.

App Tracking: Apps plead for users to press allow, but 85% of Apple iOS consumers are not opting in

The data is in: most users do not opt in to third-party tracking

Mobile app analytics company Flurry is measuring how many users of iOS 14.5 are opting in to allow apps to request to track them - and so far only 15 per cent worldwide have done so.

iOS 14.5 was released on April 26 and is gradually rolling out to users with compatible iOS devices. One of its new features is enforcement of what Apple calls AppTrackingTransparency, which means that apps must request permission from the user before tracking them or accessing the Apple device identifier (IDFA).

Proposed collective action aims to take Apple to task over its 30% App Store cut on behalf of 20 million Brits

Spent money in the walled garden since October 2015?

The day ends with "y" so Apple is facing fresh legal scrutiny of its App Store policies. This time the battleground is the UK's Competition Appeal Tribunal, where a potential collective action is being launched on behalf of circa 20 million users over claims Apple's 30 per cent "tax" is excessive and unjustified.

The claim, brought by King's College academic Dr Rachel Kent, aims to pry up to £1.5bn from Apple's coffers and includes anyone who purchased paid apps, content, or subscriptions using an iPhone or iPad after 1 October 2015.

Kent alleges Apple has abused its control over the iOS platform by preventing the entrance of other app marketplaces, and forcing developers to pay onerous fees to distribute software and in-app content through the App Store.

Preliminary report on Texas Tesla crash finds Autosteer was 'not available' along road where both passengers died

Probable cause of accident and fire still under investigation

The US National Transportation Safety Board (NTSB) has published a preliminary report into last month's fatal crash involving a 2019 Tesla Model S in Texas.

The crash happened at approximately 21:07 local time on 17 April this year. Two men entered the car, one in the driver's seat and the other in the front passenger seat (according to home security camera footage).

The Tesla then drove off, travelled about 167 metres before leaving the road on a curve, driving over a curb, hitting a drainage culvert, a raised manhole and a tree, the report found.

Intel throws sand in the face of 'musclebooks' with 10nm Tiger Lake tech

11th-gen Core H has nice new touches, but pitch is usual 'a new PC will be faster and smaller and lighter than an old PC' promise

Intel is talking up a new generation of laptop and mobile workstation CPUs that it says will deliver modest performance gains and lighten laptops for power users.

The new "Tiger Lake" range – officially the 11th-generation Core H – is built on a 10nm process and employs Willow Cove [cores] and SuperFin 10nm transistors. PCIe4 and Wi-Fi 6 are omnipresent. Some models offer per-core voltage control and the kind of overclocking opportunities previously found only on CPUs destined for desktops.

Chipzilla pitched most of the new models at "enthusiasts" – a word describing folks who like gaming on their portable PCs, feel confident enough to twiddle a few nerd knobs, but aren't going to get into water cooling any time soon.

Another platform on which Java will not run – platform 1 of Newcastle's Central Station

What is Geordie for bork?

Bork!Bork!Bork! It's a blessed respite for Microsoft's wares today as it appears that it is Java's turn to disgrace itself on platform 1 of Newcastle upon Tyne's Central Station.

In this case it is the Java Platform SE binary that has fallen over. The version of Windows on which it is running looks decidedly old hat to us, and eagle-eyed Reg reader Dan who sent us the snaps said fans of obsolescence will be delighted to learn that Windows XP splash screen can also occasionally be seen on the screens of some ticket gates.

Be that as it may, the Windows shell on display looks decidedly out of date. We can only hope that the same does not apply to the Java licence, otherwise the next train might be stuffed full of lawyers of the big and red variety.

43 years and 14 billion miles later, Voyager 1 still crunching data to reveal secrets of the interstellar medium

Gazing into the void for at least a few more years yet

Nearly nine years after leaving the solar system, and decades beyond its original mission, Voyager 1 is still gathering valuable data, providing plasma readings to continuously sample the density of the interstellar medium.

Scientists at Cornell University have used data from the spacecraft, first launched in 1977, to uncover a weak signal that details interstellar plasma density over about 10 au (astronomical unit, roughly the distance from Earth to the Sun) with an average sampling distance of 0.03 au, according to a paper in Nature Astronomy.

Voyager 1, whose original mission was supposed to finish in 1980, crossed the heliopause in 2012, making it the first human-made object to do so. This gave researchers an opportunity to directly measure activity outside the solar system, or at least as much as the spacecraft's ageing arsenal of instruments would allow.

Compsci boffin publishes proof-of-concept code for 54-year-old zero-day in Universal Turing Machine

Patch your devi... oh, hang on a sec

A computer science professor from Sweden has discovered an arbitrary code execution vuln in the Universal Turing Machine, one of the earliest computer designs in history – though he admits it has "no real-world implications".

In a paper published on academic repository ArXiv, Pontus Johnson, a professor at the KTH Royal Institute of Technology in Stockholm, Sweden, cheerfully explained that his findings wouldn't be exploitable in a real-world scenario because it pertained specifically to the 1967 implementation [PDF] of the simulated Universal Turing Machine (UTM) designed by the late Marvin Minsky, who co-founded the academic discipline of artificial intelligence.

Yet what the amusing little caper really brings to the world is a philosophical point: if one of the simplest concepts of a computer is vulnerable to user meddling, where in the design process should we start trying to implement security features?

Overdue: After a 2-year £12m delay, Northern Ireland Libraries looks to close chapter on Fujitsu saga

Launches open tender for new £60m deal

Northern Ireland Libraries is launching a formal procurement of a £60m IT contract to replace incumbent supplier Fujitsu following a two-year delay costing taxpayers some £12m.

According to a tender notice, the public-sector organisation responsible for libraries in the UK territory wants to "secure a strategic partner who will deliver modern and innovative IT services."

"Initially the requirement is to manage the legacy services for a period of time whilst planning and implementing new systems and services," the notice said. "It is envisaged this will entail a combined transition and transformation phase and it is essential that continuity of day to day library services is maintained throughout."

Train operator phlunks phishing test by teasing employees with non-existent COVID bonus

Someone at West Midlands Trains approved nasty cybersecurity drill

UK rail operator West Midlands Trains sent an email to 2,500 employees to thank them for hard work during COVID and promised a one-time bonus as a reward, but that lovely news turned out to be phishing training. Needless to say, it did not go over well.

The deliberately inauthentic email first thanked staff for their hard work, then added: "We realise that a huge strain was placed upon a large number of our workforce as a result of COVID-19 ... and we would like to offer you a one-off payment to say thank you for all of your hard work over the past 12 months or so."

Readers were told to click on a link to register for their bonus, but those who followed instructions were sent news of their infosec failings and offered handy tips for the future like "be vigilant with all links and attachments" and "never click on a link that looks suspicious."

Microsoft embraces Linux kernel's eBPF super-tool, extends it for Windows

This early-stage project is not a fork, Redmond insists

Microsoft on Monday launched an open source project to make a Linux kernel tool known as eBPF, short for Extended Berkeley Packet Filter, work on Windows.

Inspired by network packet filtering and capture software dubbed Berkeley Packet Filter, eBPF is a register-based virtual machine designed to run custom 64-bit RISC-like architecture via just-in-time compilation inside the Linux kernel. As such, eBPF programs are particularly well-situated for debugging and system analysis, such as tracing file system and registry calls.

eBPF's relationship with the Linux kernel has been likened to JavaScript's relationship with web pages – it allows Linux kernel behavior to be modified by loading an eBPF program that's executed, and without changing actual kernel source code or loading a kernel module.
