Lenovo has announced a wide range of new tablets and hybrid hardware, all running either Android or Windows 8.1.Follow the links below for a detailed overview of Lenovo’s latest device announcements, all of which fall into its Yoga range of versatile hardware.The standout feature of Lenovo’s Yoga Ultrabooks has always been the clever hinge, which allows the screen to be folded over to create a tent-like stand, rotated around to keep the keyboard out of the way, or laid flat for a tablet-like experience.For the Yoga 3 Pro, Lenovo has redesigned the hinge, likening it to a metal watch band, and building it from 800 pieces of steel and aluminum.Storage is managed by a 256GB SSD, plus there is a 4-in-1 card reader on the 12.8mm chassis.It’s joined by two USB 3.0 sockets, and a Micro HDMI port.
Circuit breakers broke bad, workload moved but array flipped out under heavy loadSalesforce.com has revealed that a bug in the firmware of its storage arrays was behind last week's data loss incident.That mess took the company's NA14 instance offline, so it took steps to move it into a Chicago data centre.Once these timeout conditions began, a single database write was unable to successfully complete, which caused the file discrepancy condition to become present in the database.The data loss came about because while Our internal backup processes are designed to be near real-time, however the local copy of the database had not yet completed.Salesforce says the circuit breakers that started the mess passed March 2016 tests, but have been replaced anyway.We do know, thanks to a 2013 post by site reliability engineer Claude Johnson that Salesforce has in the past used ZFS and Solaris-powered servers for storage.
In an ideal world, computers would only have one type of data storage, but thanks to the laws of physics and businesses, we have two main types three if you count CPU L caches .Previous PCM implementations only used 1 bit per cell, basically equivalent to storing either 0 or 1 2 values ."Someday" being the operative word here.As no actual commercially available implementation has been launched yet, we can't really speculate on how viable PCM will be as a replacement for both DRAM and flash.As mentioned, it is a topic of interest in the wider computing industry, including other companies.Suffice it to say, whoever is able to come out with a wallet-friendly and reliable solution first could very well end up in the annals of computing history as the pioneers of the new age of computer memory.
The breakthrough involves phase-change memory PCM which IBM has successfully achieved storing three bits of data per cell for the first time, compared to previous demonstrations of storing one bit per cell.PCM is much more durable than flash – it can last something like 10 million write cycles compared to the average flash USB stick which endures around 3,000 write cycles – and it's way faster, coming closer to DRAM performance, but with one big difference: it doesn't lose data when switched off like DRAM.Significant cost reductionDr Haris Pozidis, manager of non-volatile memory research at IBM Research, commented: "Phase change memory is the first instantiation of a universal memory with properties of both DRAM and flash, thus answering one of the grand challenges of our industry.The new memory tech could have implications across a range of uses, including providing blazingly quick storage for cloud and IoT applications, and boosting performance of the likes of machine learning.Businesses could see entire databases stored in PCM enabling ultra-fast querying, and of course this will also make a major difference to smartphones.IBM envisions hybrid applications with PCM running alongside traditional flash storage in a phone, but with the OS stored in the PCM so when you switch your phone on, it loads almost immediately and you're staring at your home screen before you've had time to bat an eyelid.
The goal is a peer-to-peer serverless hosting, storage and serving solution that is DDOS-resistant, fault-tolerant, has zero-downtime, and is censorship-resistant.This gave way to Web 2.0 and a "Faustian bargain" which traded control of content, access and user data for scalable hosting infrastructure which is kept cheap or free by selling on their profile info to third parties for targeted advertising.Swarm lead developer Viktor Trón told IBTimes UK: "It occurred to the founders of Ethereum quite early on that this could be a very good skeleton for a new generation of the web, a vision they termed Web 3.Firstly, as a content distribution system for Dapps; secondly for certain application logic which is not consensus critical which you don't want to be replicated on every node, think the database component of web applications; and thirdly, the blockchain itself could be stored in a decentralised way."And similarly if you had a decentralised Airbnb, then you would have all the accommodation offerings with the photos of everything on Swarm.The solution proposed in the orange paper uses cryptographically verifiable proof of custody combined with erasure coding a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces and stored across a set of different locations or storage media .
In PCM cell, '0' is programmed to be written in the amorphous phase or a '1' in the crystalline phase, or vice versa while low voltage is applied to read the bits back as in re-writable Blue-ray Discs.For storing 3 bits per cell, the scientists have developed a set of drift-immune cell-state metrics and drift-tolerant coding and detection schemes.IBM Research - Zurich manager of non-volatile memory research and one of the authors of the paper Dr. Haris Pozidis said: "Phase change memory is the first instantiation of a universal memory with properties of both DRAM and flash, thus answering one of the grand challenges of our industry."Reaching 3 bits per cell is a significant milestone because at this density the cost of PCM will be significantly less than DRAM and closer to flash."With the technology, scientists are expecting that a mobile phone's operating system could be stored in PCM, which will help it launch in a few seconds.The technology could also be used in enterprise environments, as the entire databases could be stored in PCM, allowing faster query processing for time-critical online applications, such as financial transactions.
They re easy to clean and move especially if they have wheels , but don t look the best.If you have plastic storage that s an eyesore in your home, here s how to give it a facelift.You probably already have everything you need: cardboard, patterned paper like wrapping paper , glue, and scissors.Depending on your drawers, you may also need a bit of tape to secure the insert to the front of the drawer.Fold the paper over the cardboard, gluing the extra onto the back of the cardboard.If the sides of your drawers are visible too, you can make inserts for each side of the drawer using the same process.
Big Blue researchers demonstrate reliable phase-change memory PCM Scientists at IBM Research said they have for the first time reliably stored 3 bits of data per cell and retained the information at elevated temperatures , a technical advance that makes phase-change memory PCM an alternative to flash storage.Long Time ComingIBM Stand MWC 2016IBM scientists in Zurich first introduced PCM technology way back in 2011, when they presented a whitepaper at the 3rd IEEE International Memory Workshop in Monterey, California.Researchers believe this means it could be used in either standalone PCM, as well as hybrid applications that combines PCM and flash storage together, with PCM acting as an extremely fast cache.This is how re-writable Blue-ray Discs store videos, said IBM Phase change memory is the first instantiation of a universal memory with properties of both DRAM and flash, thus answering one of the grand challenges of our industry, said Dr. Haris Pozidis, an author of the paper and the manager of non-volatile memory research at IBM Research – Zurich.Reaching 3 bits per cell is a significant milestone because at this density the cost of PCM will be significantly less than DRAM and closer to flash.The chip consists of a 2 2 Mcell array with a 4- bank interleaved architecture.
Better-than-binary multi-level memoryMemory could be getting an upgrade beyond the two states used in binary, as researchers have designed a magnetic element with six stable magnetic states, according to a paper published in Applied Physics Letters.They consume less power, allow memory to be written and read at a quicker pace, and last longer."Furthermore, since MRAM is different in its nature from flash, there is no reason that it should suffer from the drawbacks of multi-level-cell flash memory."This technique, known as spin-orbit torque switching, shows that more memory can be packed over a tighter space.Researchers believe that even more magnetic states can be created by adding more layers of magnetic film – crossing four ellipses could give eight magnetic states.The researchers said they would like to "progress towards fabricating a prototype" that would help them "convince the magnetic memory industry to make a shift towards multi-level magnetic memory."
So said Ed Healy, CEO at data centre management company RF Code.He said that it is essential for a provider to understand their total capacity from a power perspective to keep customers updated of how much of it they are using and when.This capacity planning will also help data centres improve their scalability and flexibility by giving them insights into business needs.According to Paul Lewis, data centre manager at colo Aegis Data, "the growth of IoT will force colocation facilities to adopt greater flexibility".Lewis said: "In order to accommodate the sheer volume of IoT we will see clients increasingly demanding greater scalability capabilities from their providers.In the commercial data centre sector IOT is changing customer expectations.
Dell has updated its Storage Centre Operating System 7 SCOS 7 in its latest attempt to grab a piece of the expanding flash-based storage architecture market.In addition, the SCOS 7 has been designed to enhance support for virtualisation and cloud strategies, and help increase portfolio-level investment protection."One of the core capabilities of the SC architecture over the last few years it has been to mix different kinds of drives together, so we can blend the characteristics of performance, capacity and cost.According to the company, the SCOS 7 also elevates storage management control as a future-proofed capability.With Dell's new Live Migrate feature, storage administrators can now move volumes quickly and seamlessly between arrays, optimising and re-balancing the environment without interrupting workloads and without purchasing additional virtualisation hardware or software.Lastly, Dell also released the Dell Storage Manager DSM software, to help unify the storage ecosystem in the data centre.
SC, or Storage Center, is the operating system software for Dell's SC series arrays, originally branded Compellent, and generally Fibre Channel SANs.Dell SCv2000 storage arrayDedupe and compression enables SC arrays to offer all-flash storage for less than $0.45/GB, Dell claims this the lowest in the industry*, and hard drive tiers under $0.10/GB for net effective capacity**.Storage admins can move volumes non-disruptively between arrays.Quality of service features to help admins automatically ensure higher priority workloads get the resources they need from the array.AvailabilitySCOS 7 will be delivered as a free firmware upgrade for SC Series customers with a current support contract.PS 9.0 firmware, available this month at no charge with a current support contract, provides unified management and cross-platform replication capabilities across PS and SC series arrays.
With new software, Storage Center and EqualLogic systems get common management and replicationDell's sign on the show floor of Oracle OpenWorld 2015.New operating systems will help to bridge the gap between Dell s Storage Center and EqualLogic PS arrays, giving administrators a single management interface and a way to replicate data between the two systems.Only now can they be managed with one tool and carry out bi-directional replication.So with Dell about to take over EMC, customers may be in for a long wait for things like unified management, Conner said.That comes as businesses look to IT infrastructure as a competitive asset.To meet that demand, Dell has added quality-of-service features to SCOS 7.

Dell s enterprise storage operating system follows introduction of a network OS earlier this yearDell continues to round out its enterprise offerings with the official release of Storage Center Operating System 7 SCOS 7 .Dell claims that SCOS 7 will help lower acquisition costs across flash and hybrid arrays; help lower lifecycle costs elevated simplified management; and enhance support for virtualisation and cloud strategies.This allows sStorage administrators to move volumes quickly and seamlessly between arrays, optimising and re-balancing the environment without interrupting workloads and without purchasing additional virtualisation hardware or software.Dell of course is in the middle of a hugely expensive purchase of storage giant EMC, that will see the PC maker take on about $59.1bn £41bn in debt as a result of the acquisition.Last month EMC revealed its first quarter results that made for uncomfortable reading for new owner Michael Dell.Whilst it managed a modest profit increase, sales were down to $5.5bn £3.8bn from $5.6bn £3.9bn a year earlier.
Many of us never pause to consider what that means, but data is growing exponentially — with no end in sight.There are already more than a billion cellphones in the world, emitting 18 exabytes 1 billion gigabytes of data every month.And while interesting advances are being made in data storage on DNA molecules, for now, realistic data storage options are still a little less sci-fi sounding.Here are four viable solutions to our storage capacity woes.The hybrid cloudWe all understand the concept of the cloud.The refrigerator-sized box can store up to 16 petabytes of data, and co-founder John Hayes believes that amount can be doubled by 2017.
Cloud storage, at its most basic, is the storage of data online in the cloud.This means that a company's data is being stored somewhere else other than on a hard disc in the user's PC or Mac.The data is maintained, managed, backed up remotely and made available to users via the Internet and it can provide some essential benefits.In the public cloud model the data is stored in global data centres and data can be spread across multiple regions covering continues.Customers often pay on a per-use basis with the leading providers Microsoft Azure, Google Cloud Storage and Amazon Web Services.While there are multiple benefits to using cloud storage, one disadvantage is the limitations of bandwidth.
This requirement has resulted in the market being swamped with different services vying for your business.By working with Microsoft, the company has integrated closely with Office so that it can be used seamlessly.Dropbox is available via apps that can be installed on your desktop or mobile device.Apps are supported on iOS, Android, Blackberry and Windows.The service offers 5GB free, although students can get 1TB, and Office 365 subscribers also get 1TB 'free'.A free 5GBs of storage is available but this can be hiked up to 50GB for just 79pence a month, showing just how cheap cloud storage can be.
Cloud Constellation s system, called SpaceBelt, would be a one-stop shop for data storage and transport, says CEO Scott Sobhani.Need to set up a new international office?Most computer gear in space today is more expensive and less advanced than what s on the ground, satellite analyst Tim Farrar of TMF Associates said.A petabyte can already fit on a few shelves in a data-center rack, and each generation of storage gear packs more data into the same amount of space.Any advantage that financiers could gain over competitors using fiber networks, which usually have a few seconds of end-to-end latency, would help them make informed trades more quickly.Under the United Nations Outer Space Treaty of 1967, the country where a satellite is registered still has jurisdiction over it after it s in space, said Michael Listner, an attorney and founder of Space Law & Policy Solutions.
Azure Premium Storage users can now replicate their workloads onto SSDsMicrosoft is offering some Azure Site Recovery customers the option of using flash storage, rather than traditional hard drives for their backup services.Azure Site Recovery is Microsoft s flagship backup service, and now users of Microsoft s Azure Premium Storage will get access to SSDs, a move the company claims will boost the speed of cloud applications and their backup counterparts in storage.Premium If you are running I/O input/output intensive enterprise workloads on-premises, we recommend that you replicate these workloads to Premium Storage, said Poornima Natarajan, a Microsoft Cloud and Enterprise manager.CEO Satya Nadella At the time of a failover of your on-premises environment to Azure, workloads replicating to Premium storage will come up on Azure virtual machines running on high speed solid state drives SSDs and will continue to achieve high-levels of performance, both in terms of throughout and latency.EncryptionNatarajan also gave customers more information about the upcoming Azure Storage Service Encryption SSE for data at rest.SSE for Data at Rest will help customers protect their data to meet company regulations, according to Natarajan, with Storage Service Encryption encrypting data prior to persisting to storage and decrypting prior to retrieval.
