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. ®

Kasten by Veeam adds ransomware detection to K10 data management platform

Catching compromise attempts before kicking off that recovery plan

Kubecon Veeam acquisition Kasten kicked off this year's Kubecon with an updated version of its K10 product, aimed at securing the Kubernetes container orchestration platform.

Now known as "Kasten by Veeam", the company told the Valencia-based conference that version 5 of the K10 Kubernetes backup and data protection suite includes extra ransomware defenses.

K10 has received a number of updates since Kasten's acquisition by Veeam. Version 4.5 added coverage for platforms including Kafka, Cassandra, and the K3s Kubernetes distribution.

Financial giant Santander: 80% of our IT infrastructure in cloud

'Most challenging element of migration likely remains' warns analyst

Spanish financial giant Santander has migrated 80 percent of its core banking IT infrastructure to the cloud as part of its $20.8 billion (€20 billion ) modernization programme, with the help of in-house software created by resident developers.

Readers hoping for a tale of disaster and woe may be sorely disappointed as the bank seems to have made steady progress in the past year compared to April 2021 when some 60 percent of its infrastructure was delivered off-premise.

The $48.3 billion (€46.4 billion) revenue financing giant has a presence across Europe, South America, Asia and North America. It made $3.17 billion (€3.053 billion) of its attributable profit of $8.44 billion (€8.124 billion) in the US last year, it said in its 2021 fy results.

Elon Musk 'violated' Twitter NDA over bot-check sample size

<5% figure was based on 100 accounts if you're wondering

Last week Elon Musk hit pause on his Twitter acquisition over the platform's "less than 5 percent" bot figure.

The Register asked the microblogging website how it made the estimate and was stonewalled, but in ensuing discussions over the weekend, Musk blurted out that the sample size was 100 accounts.

One Musk fan asked how the userbase might help uncover the "real percentage" of fake accounts and was told:

Python is getting faster: Major performance tweaks on horizon

Instagram, Microsoft responsible for lifts coming in version 3.11 and beyond

The next version of the standard Python interpreter, CPython, is expected in October. It will include significant performance improvements and support for running inside the browser.

Last week, the first Python language summit since 2019 took place in Salt Lake City. At the event, the language's development team announced various changes for the forthcoming version of the language, as well as its near future. The Reg has covered some future improvements before, and as they get closer, details are becoming clear, as well as what's coming in Python 3.12.

There are multiple editions of Python out there, including interpreters for the JVM and .NET CLR, as well as compilers, but the core implementation of the language is the CPython interpreter. This has some well-known limitations, including the Global Interpreter Lock or GIL, which prevents the language from taking full advantage of multicore processors.

EU-US Trade and Technology Council meets to coordinate on supply chains

Agenda includes warning system for disruptions, and avoiding 'subsidy race' for chip investments

The EU-US Trade and Technology Council (TTC) is meeting in Paris today to discuss coordinated approaches to global supply chain issues.

This is only the second meeting of the TTC, the agenda for which was prepared in February. That highlighted a number of priorities, including securing supply chains, technological cooperation, the coordination of measures to combat distorting practices, and approaches to the decarbonization of trade.

According to a White House pre-briefing for US reporters, the EU and US are set to announce joint approaches on technical discussions to international standard-setting bodies, an early warning system to better predict and address potential semiconductor supply chain disruptions, and a transatlantic approach to semiconductor investments aimed at ensuring security of supply.

US cops kick back against facial recognition bans

Plus: DeepMind launches new generalist AI system, and Apple boffin quits over return-to-work policy

In brief Facial recognition bans passed by US cities are being overturned as law enforcement and lobbyist groups pressure local governments to tackle rising crime rates.

In July, the state of Virginia will scrap its ban on the controversial technology after less than a year. California and New Orleans may follow suit, Reuters first reported. Vermont adjusted its bill to allow police to use facial recognition software in child sex abuse investigations.

Elsewhere, efforts are under way in New York, Colorado, and Indiana to prevent bills banning facial recognition from passing. It's not clear if some existing vetoes set to expire, like the one in California, will be renewed. Around two dozen US state or local governments passed laws prohibiting facial recognition from 2019 to 2021. Police, however, believe the tool is useful in identifying suspects and can help solve cases especially in places where crime rates have risen.

RISC-V needs more than an open architecture to compete

Arm shows us that even total domination doesn't always make stupid levels of money

Opinion Interviews with chip company CEOs are invariably enlightening. On top of the usual market-related subjects of success and failure, revenues and competition, plans and pitfalls, the highly paid victim knows that there's a large audience of unusually competent critics eager for technical details. That's you.

Take The Register's latest interview with RISC-V International CEO Calista Redmond. It moved smartly through the gears on Intel's recent Platinum Membership of the open ISA consortium ("they're not too worried about their x86 business"), the interest from autocratic regimes (roughly "there are no rules, if some come up we'll stick by them"), and what RISC-V's 2022 will look like. Laptops. Thousand-core AI chips. Google hyperscalers. Edge. The plan seems to be to do in five years what took Arm 20.

RISC-V may not be an existential risk to Intel, but Arm had better watch it.

How CXL may change the datacenter as we know it

Bye-bye bottlenecks. Hello composable infrastructure?

Interview Compute Express Link (CXL) has the potential to radically change the way systems and datacenters are built and operated. And after years of joint development spanning more than 190 companies, the open standard is nearly ready for prime time.

For those that aren’t familiar, CXL defines a common, cache-coherent interface for connecting CPUs, memory, accelerators, and other peripherals. And its implications for the datacenter are wide ranging, Jim Pappas, CXL chairman and Intel director of technology initiatives, tells The Register.

So with the first CXL-compatible systems expected to launch later this year alongside Intel’s Sapphire Rapids Xeon Scalables and AMD’s Genoa forth-gen Epycs, we ask Pappas how he expects CXL will change the industry in the near term.

Lawyers say changes to UK data law will make life harder for international businesses

Concerns raised over government drive to implement distinct post-Brexit policy

Legal experts say UK government plans to create new data protection laws will make more work and add costs for business, while also creating the possibility of challenges to data sharing between the EU and UK.

Last week, the Queen's Speech – in which the British government sets out its legislative plans – said the ruling Conservative party planned to replace the EU's General Data Protection Regulation (GDPR) to ease the burden on business with an approach to data protection that encourages innovation while retaining protection of personal data and privacy.
