Oracle unrolls tape roadmap

Three generations to 20TB reel


Details have emerged from yesterday's webcast of Oracle's tape roadmap showing three format and SL8500 library, reaching a 20TB cartridge and 2 exabyte library in 2015.

As we thought it is a three-generation job, starting off from the current T10k-B tape format with 1TB raw capacity and a 120MB/sec throughput. The current StreamLine 8500 (SL8500) library has a 100PB capacity and a 276TB/hour bandwidth.

Oracle sees a generation 3 tape - the T10k-B being the generation 2 tape and the T10k-A the generation one - so let's call it the T10k-C, with 3 - 5TB capacity and 180 - 270MB/sec throughput. We don't know if these numbers are ranges with the product fitting in there somewhere, or the upper and lower bounds of versions of the T10k-B. We're going to assume a range until Oracle tells us different.

The SL8500 at this point will have a 300-500PB capacity and a 441-621TB/hr throughput. Looking at the relationship between tape capacity and library capacity we see the latter is 100,000 times the former in both cases indicating that the library's slot count has not changed.

If we divide the 2010 SL8500's throughput of 276TB/hr by the T10k-B drive's throughput of 120MB/sec (276/120) we get a ratio of 2.3. Doing the same math for the 2011 SL8500, meaning 424/180, we get the same ratio of 2.3, indicating that the number of drives in the SL8500 hasn't changed.

If we do that division with the higher throughput numbers, meaning 621/270, we still get the same ratio. It appears that the SL8500 is getting its increase in capacity and throughput purely from faster drives and higher capacity tape, not from a greater number of slots and drives.

In 2013 we have a fourth generation tape, a T10k-D we'll say, with 6-10TB capacity and 270-400MB/sec throughput. The SL8500 now has 600-1000PB capacity and 621-920TB/hr throughput. Once again the slot count stays constant and so does the number of drives, using the same math as before.

The gen 5 tape, a T10k-E, appears in 2015 with a 12-20TB capacity and 400-600MB/sec throughput. At this point the SL8500 has a 1.2EB (1,200PB)-2EB (2,000PB) capacity and a 920-1380TB/hr throughput, the slot and drive count remaining constant again.

It seems odd that in five years Oracle does not intend refreshing the SL8500 library with a higher slot and drive count. By 2015 it will be a quite dated design.

Oracle's EVP for storage and servers, John Fowler, used the 20TB capacity in summary slides in his presentation. If the 12-20TB capacity is a range then a 12TB actual product will under-deliver on the 20TB upper bound by a considerable margin. It looks as if Oracle is running the risk of over-promising and under-delivering.

This roadmap should reassure StorageTek tape users that Oracle intends to be an active steward of their interests and does not want to see them desert and join the ranks of IBM or SpectraLogic library users. ®


Airline software super-bug: Flight loads miscalculated because women using 'Miss' were treated as children

Weight blunder led to wrong thrust used on takeoff, says UK watchdog

A programming error in the software used by UK airline TUI to check-in passengers led to miscalculated flight loads on three flights last July, a potentially serious safety issue.

The error occurred, according to a report [PDF] released on Thursday by the UK Air Accidents Investigation Branch (AAIB), because the check-in software treated travelers identified as "Miss" in the passenger list as children, and assigned them a weight of 35 kg (~77 lbs) instead of 69 kg (~152 lbs) for an adult.

The AAIB report attributes the error to cultural differences in how the term Miss is understood.

W3C Technical Architecture Group slaps down Google's proposal to treat multiple domains as same origin

First Party Sets 'harmful to the web in its current form'

A Google proposal which enables a web browser to treat a group of domains as one for privacy and security reasons has been opposed by the W3C Technical Architecture Group (TAG).

Google's First Party Sets (FPS) relates to the way web browsers determine whether a cookie or other resource comes from the same site to which the user has navigated or from another site. The browser is likely to treat these differently, an obvious example being the plan to block third-party cookies.

The proposal suggests that where multiple domains owned by the same entity – such as google.com, google.co.uk, and youtube.com – they could be grouped into sets which "allow related domain names to declare themselves as the same first-party."

South Africa's state-owned energy firm to appeal after court rules Oracle does not have to support its software

Eskom disputes results of Big Red audit

South African electric utility Eskom is set to appeal against a court decision that refused to force Oracle to support software used by the firm while a licensing and payment dispute is settled.

In a case that dates back to 2019, Johannesburg High Court dismissed an attempt by Eskom to compel the global software giant to renew support services until April 2022.

The decision leaves the state-owned electricity company reliant on an "interim risk mitigating processes... to reduce the risk of its operations being disrupted."

Xen releases a new version 4.15 after a slightly delayed development process

Teases new ‘Hyperlaunch’ tech that will allow booting of whole VM fleets

The Xen project has released another upgrade to its open source hypervisor.

Development of this new cut – version 4.15 – proved a little trickier than expected, with initial plans for three release candidates and a March 23rd release stretching to five release candidates and release today, April 8th.

Was it worth the wait? Xen’s feature list highlights the new ability to export Intel Processor Trace data from guests to tools in dom0, which means tools like Intel’s kernel fuzzer have more to work with and thus a better chance of spotting code nasties.

Website maker Wix embarks on weird WordPress-trashing campaign, sends 'influencer' users headphones from 'WP'

'Creepy' videos liken CMS giant to 'absent, drunken father' – but its market share is only rising

Hosting company Wix is apparently running a bizarre campaign in an attempt to win over WordPress customers, causing WordPress founder Matt Mullenweg to accuse Wix of "dirty tricks."

WordPress is the content management system giant, with a 64.7 per cent market share and used in some measure by 40.9 per cent of active websites, according to W3Techs. Wix by contrast has a 2.4 per cent market share, though that is enough to place it fifth, behind Squarespace but above Drupal.

Wix kicked off its new campaign by apparently sending expensive Bose noise-cancelling headphones to selected people they considered to be influencers – the odd thing being that the gift was marked "Yours WP," though the sender was Wix.

Beloved pixel pusher Paint prepares to join Notepad for updates from Microsoft Store

You cannot kill what does not die

Microsoft Paint has followed its long-lived chum Notepad into the howling wilderness of the Microsoft Store.

It has been a while coming, but last night's Dev Channel Insider build of Windows 10 (21354) has made the MSPaint app updateable via the Microsoft Store.

The change, which was accompanied by a whizzy new icon for the aged bitmap editor, will allow Microsoft to tinker with the app without requiring a full-on Windows update. The same fate has already befallen the Notepad text editor, although we fervently hope those within the walls of Redmond fight the urge to fiddle with it too much.

Gitpod ditches Eclipse Theia for Visual Studio Code under redesign, sponsors new dev experience event

'Allowing everyone to use their favourite IDE just makes a lot of sense'

Gitpod, which provides remote environments for testing and debugging code, has shifted to Visual Studio Code from Eclipse Theia and is sponsoring a new event called DevX Conf, focused on the developer experience.

The idea behind the open-source Gitpod platform is that developers code, build, test, and debug in a remote workspace implemented as a Docker container, running on Kubernetes, and accessed via a web browser.

There are integrations with GitLab, GitHub, and Bitbucket, and the official IDE is Eclipse Theia – or was. "The IDE you get is now the original VS Code," co-founder Sven Efftinge told us.

Apple extends Find My support to third-party vendors including Belkin, Dutch bike maker VanMoof, and Chipolo

Expensive bike, earpods can now be tracked from inside the walled garden

An upgrade to Apple's Find My app has added support for devices from third-party manufacturers including gadget-tracking startup Chipolo, Belkin, and niche Dutch bike maker VanMoof.

Find My is a service that allows iPhone, iPad, Mac, and AirPod owners to locate their missing devices through a dedicated application or website. Until now, Apple had refused to support third-party vendors, forcing careless punters to rely on other services, such as Tile or (ironically) Chipolo.

That's changed with the launch of the Find My Network Accessory Program, which will allow independent firms to piggyback off Apple's tech, provided they meet Cupertino's stringent privacy and security rules.

UK reseller sues Microsoft for £270m in damages claiming prohibitive contracts choke off surplus Office licence supplies

ValueLicensing also calls for action to 'restore and maintain competition and choice in the market'

Updated Microsoft is being sued by UK reseller ValueLicensing for £270m in damages over claims of restrictive contractual practices and abuse of dominance.

The claim, filed in the UK's High Court in London, asserts that Microsoft stifled the supply of preowned Microsoft licences in the UK and EEA and added clauses into contracts that restrict customers reselling their licences (in return for a discount).

"The net result," alleges the Derby-based software reseller, "has been higher prices and less choice for customers, who have been steered into cloud-based Office365 and Azure subscriptions."

Belgian police seize 28 tons of cocaine after 'cracking' Sky ECC's chat app encryption

Euro cops take $1.65bn of blow off the streets after poring over messages

The Belgian plod says it seized 27.64 tons of cocaine worth €1.4bn (£1.2bn, $1.65bn) from shipments into Antwerp in the past six weeks after defeating the encryption in the Sky ECC chat app to read drug smugglers' messages.

"During a judicial investigation into a potential service criminal organization suspected of knowingly providing encrypted telephones to the criminal environment, police specialists managed to crack the encrypted messages from Sky ECC," the Belgian police claimed, CNN reports.

"This data provides elements in current files, but also opened up new criminal offenses. The international smuggling of cocaine batches plays a prominent role in intercepted reports."

Ex-Geeks staff lose legal bid to claw back withheld training costs from final paycheques

Company acted fairly and reasonably, rules judge

Two men who quit software development firm Geeks Ltd failed to prove the company unlawfully withheld more than £2,000 from each of them to claw back its training costs, a tribunal has ruled.

The duo, named by the London South Employment Tribunal as Mr Bennett and Mr Day, both left the South London firm in 2019 after spending about two years working there.

Both claimed, in echoes of another tribunal case against Sparta Global, that Geeks had unlawfully withheld thousands from their final paycheques for unjustifiable training costs – but Employment Judge Corinna Ferguson ruled that the company acted correctly.
