Re: As a lesser mortal...
databases don't need much memory at all if you do the storage right, and big data certainly doesn't need lots of RAM, that's the whole point of the field!
Violin have a lot of really very good IP and patents. Customers have lost trust in the company so the obvious way forward is licensing the awesome tech to others. We've had people tell us that Violin came out best on every metric who then bought something else because of trust in the brand.
Re: Apple covering you breaking your iphone for 1 year...
Yes they do, take your broken cables to an Apple store and they will swap them for you. Personally I've had iPod cables for up to 10 years and not one of the 10 or so has broken so perhaps you need to teach your son and his friends how to look after their possessions better.
It clearly stated on their website, linked from the article, that they DO give a 2 year warranty in line with the EU. That page also clearly states the extra benefits of buying the Apple warranty. As I said, before the EU law changed, the Apple warranty was only one year but offered exceptionally good terms which no other company I'm aware of offered with the possible exception of Zippo.
I don't see how this is confusing. Apple comply with the letter of EU law, and offer a paid support which offers a better warranty than the EU law requires. Before the EU law came in, Apple offered a free full 1 year warranty which was considerably better than that which is required by the EU - not many companies include the terms "defects present at or after manufacture"
There is actually considerably less innovation shown here than it seems. Most vendors have drive sleds with multiple drives deep, although I think most vendors avoid attaching that many SSDs because in normal land we use SSD for bandwidth and that many SSDs on a SAS loop would kill this PDQ. It's currently not possible to have sufficient CPUs in a box that size to allow enough SAS loops to saturate those disks either. Given that Facebook are after massive capacity and lower power they would be considerably better off manufacturing new SSD disks a few inches thick with more chips in them. Fewer SAS connections would lower the power requirements further while a 5" thick SSD would be large enough to incorporate its own cooling solution. It would also reduce their costs for engineers replacing them because they would fail less often and there would be fewer to swap out on failure. Given their desire for extremely low access speed and high capacity I'm also amazed they don't write custom firmware (maybe they do?) to utilise the spare capacity in SSDs which is usually reserved for replacing dead blocks. In enterprise drives there is double the stated capacity usually so this would be a much more worthwhile project for them than cocking about with 3D printers and quadcopters. Of course, I don't have billions of dollars to my name so clearly they are smarter than I am :)
Performance of disks
Twice as fast as previous disks? Perhaps the 12Gb SAS can go twice as fast as 6Gb SAS but this disk has similar sustained performance to older disks. That said, the SAS loop is becoming quite the bottleneck in SAN systems these days so it's good to see an improvement even if the disk isn't able to get much benefit from it.
So they taught it all about cancer and then...what, it couldn't be arsed* so it's cocking about with apps now instead? What if it gets bored of apps as well, will it just go and play flappy birds instead?
*I'm assuming here that it didn't in fact cure cancer since I'm sure I'd have seen that in the news.
Re: Make it free
"But, since MS also collects users' data to "..improve users' experience.." now, it has no right to charge (in cash) now."
Actually that data was used to drive the interface developments you've seen in Windows 7 and Windows 8. They removed the stuff people who participated didn't click on, and put stuff in that they did. Sadly for commentards on here, most geeks declined to take part so the interface is now ideal for non technical users.
Does wireless power not use Induction to transfer power between wires then?
Does anyone actually use wireless power for anything other than a toothbrush? It seems to have been supported in phones for ages but I have yet to see it in use
Re: A couple of comments
"at that time there was no concept of flash cache which is why latency was higher."
No, it was called PAM in the old days :)
Re: how different is the design?
It's gone to PCIE v3 which is a big difference in terms of available bandwidth, something you want in a SAN if you're putting oodles of high speed ports into it. They have changed from FC8Gb to CE10/16Gb ports as standard and added a few 10GbE ports as well. I think that the new models essentially require fewer add on cards to create a viable cDOT design than the older models, certainly the 32xx models.
They use considerably less power than the older models too
Awesome, now where's that Azure integration?!
I thought this too, I don't recall there being a declaration that a list of opted out folk wouldn't be kept for later examination and therefore it's actually an opt in system for porn (ab)users who will likely be investigated in due course.
Is it me, or are they just saying they implemented VLANs on a massively over specced network? I don't see where the innovation is here, surely most reasonable network guys could distribute terabits of bandwidth without much problem given an unlimited budget.
Re: Owning music on CD and vinyl
Trouble is that with movies, the DVD/Bluray sales are holding back content owners from selling content to streaming services. At least with music they have long since given up and have allowed DRM free downloads so we have a good choice.
Re: I already have a geographically based password system
I think the vast majority could just email a one time token to you when you visit and have no password at all. The problem is that the coders who write the website often put it in because they think they should put it in.
Why would they need a new 6290 equivalent when the story is scale out now? The new boxes are clearly designed with the IO for scale out cluster mode so the requirement for a big scale up box will die with 7 mode.
That's my theory at least, they may be saving a fas8080 for the summer for all I know but I don't see how it would help fill any reasonable needs.
Re: I struggle to see how Office could be useful on a tablet
" I have a feeling Microsoft is going to try to charge the same price as desktop Office."
Office isn't sold like that any more with even business licences going Office365 only this year. These days you buy a user licence which gives you rights on up to 5 devices. If your company licences you for office on your company PC under Office 365 you should get this iPad version included in that along with your home PC and laptop. All you need to do is enter your email address.
I imagine it will be a free app in the App Store with in app activation although not sure how Apple will cope with that.
If you're consistently high on IO the SSD write caching won't help either you'll need to go to an SSD only setup otherwise just like the cache you'd run out of SSD. 3Par certainly performs better than NetApp in tests I've done so if your only requirement is performance then it's a great choice. The trouble is that HP then try to sell you legacy backup to go with it rather than trust the array and snapshots and that's where NetApp shine. HP have a similar feature set but they would rather sell a store once setup to you than let you anywhere near the future and integrated backup. They also love selling tape drives and backup servers with HP backup software. NetApp sell you two identical boxes, one for primary one for DR and you're done. They don't have the performance but they do have "future" in spades :)
Per controller, so you'd have double that in each cluster. You may need to research how FAS works if you don't already know, cache is completely different to other SANs. All writes are sequential to the spinning disk so that 16GB NVRAM is plenty to cache writes while the several TB of flash card is plenty for read cache which stops the spindles being interrupted for read operations. Sequential writes allow around 3x the IOPS of random writes in the real world, although if you test a laptop hard disk you'll find the physical disk manages around 10x sequential if that's all it's doing.
Re: What is the point of defining channel bonding?
At that speed your cache will only last a second or so before disk is a bottleneck, so presently Violin type setups are the only ones where this issue is not present.
As for the latency, you're using vendor marketing figures rather than testing. Again though, solutions like Violin make these differences painfully obvious where the SAN does give near zero latency and suddenly your FCoE latency looks immense compared to native FC.
Re: What is the point of defining channel bonding?
As long as you're defining speed only in terms of throughput then yes. Until arrays deliver more throughput though you're far better off going for latency and that currently means fibre channel without the Ethernet gunking it up. Considering the back end disk loops on most modern SAN is 6Gbps SAS you'd need an awful lot of loops to require these kinds of bandwidths. Unless we go back to FC loops of course...
Re: You nailed it Trevor
I wasn't suggesting there were cost savings I was responding directly about small companies not wanting to manage the IT which Azure helps a lot with. It's certainly not cheaper and can be more expensive but I think it will start to take off one way or another.
Re: You nailed it Trevor
I think in a very few years those customers will be on Azure and Office365 for the most part. This year MS will be binning the full Office install and licence so they will be forced to Office365 and the rest will probably follow in short order.
Re: Shouldn't there really be a disclaimer...
Not sure I'd call that an advert. To me it reads that most IT guys will bring you a tried and tested solution based on common hardware while Big Trev will randomly pick from an assortment of new toys he's found and put together a unique design based on assumptions about how the technology will perform. He will then make it complex enough that you can't possibly replace him.
Perhaps I read it wrong though :)
I should add that for once I kind of agree with Mr Pott. It takes a completely different mentality to deal with smaller customers and I hate being asked to work in that kind of environment because it just feels like chaos after an enterprise customer.
"typically in our industry it is 12 months as minimum"
Maybe in America but in the EU it's 2 years and UK it's 6. Hardware breaking has nothing to do with this though, this is about HP refusing to give fixes which were previously freely available to fix the software bugs they put in.
I think this is illegal in the UK. They are obliged to support for 6 years from date of purchase for warranty. Since they agree to give security patches, and they are obliged to fix defects present at manufacture there really isn't much left other than feature improvements but then they will need to produce a vast array of firmwares, some with just fixes and some with just features.
Re: I hate to say it...
Re: @Oliver Mayes @Corinne
"In my experience, change control is never applied to requirements. It would be good if it could, but generally, it's not, especially on something with a duration measured in a few weeks."
Perhaps that's because you aren't applying it? Those of us who don't get this apparent stream of crap coming down seem to the the same group who understand how to deal with change control properly. Just saying :)
Re: Few CIOs or VP ITs can code
"You just get told "we've promised X to dept Y in timeframe Z"
No, I get asked. If you're getting told it means that either you are not senior enough to be consulted (in which case, you're not senior enough to be told off) or you're not considered worth consulting. Either way, if you genuinely are senior enough to be part of the discussion, the above message is the point at which you professionally disagree with them and say no, giving reasons.
I hate to say it...
Coders are the new factory workers and this is setting up that exact scenario. The country needs a large number of people who can write code to fulfil a design done by someone else. They don't need to know about web design, they don't need to know how to write an algorithm, they just need to be able to write and debug code having followed what someone higher up has produced.
Unfortunately for these education people, they will need to read and write. Judging by the school output I've seen this would appear to also need some work.
Re: Few CIOs or VP ITs can code
"why didn't you deliver?"
If they are asking you this, it's likely that you agreed earlier you could deliver it so the fault is not with them. If they ask you to deliver something and you can't, you need to explicitly tell them you can't, and why you or anyone else won't be able to. It's the same when ordering from Amazon, if they say an item is in stock and will deliver on Thursday I have the right to moan if they don't. If I order something which isn't in print and they don't have stock and then complain they will laugh at me, just as you should with your boss if you set the situation up correctly.
When you say "close the gap" I assume you mean EMC already had a way to instantly convert between virtual disk formats and storage types. Could you please point us in the direction of this EMC technology?
I was under the impression that EMC's "unified" storage was just two boxes plugged together in a chassis so they can't even ODX between fibre channel LUNs and CIFs shares but I've not done much with EMC so could be wrong.
Missed a bit...
They can also move disks from virtual format to direct attach LUNs with the same process, so customers for instance who used VMDK for Exchange data can migrate to direct attach for proper VSS snapshot backups. This can also be useful when going from virtual to physical too and between NFS, CIFS and SAN protocols (they don't differentiate between FC and iSCSI and you can multipath between the two if you really want to.
Project shift is on Youtube at http://www.youtube.com/watch?v=OE2JCkVgv38 which is pretty cool.
The other thing is that they always mention easy migrations to cloud platforms - wouldn't it be cool if you had a NetApp in Azure and could just convert and snapmirror the machines up into the cloud? They already integrate with AWS so it's a logical next step even if they won't admit they are working on it.
I find it odd that the mainstream news continually tells us the financial crisis/recession/depression is over and things are improving yet we are continually being shown evidence to the contrary on the Reg where hundreds of thousands of people are being laid off in IT. Lay off 10000 IT people and you won't need as many HR staff, accounts staff, managers, coffee shop workers, caterers. Once their redundancy cash is gone they will stop employing plumbers and electricians and builders.
Have I missed something or is this still the downslope of a recession regardless of the upward bumps in house prices caused by people desperate to "kick start" the economy?
Re: In 12 months
At least 50% of them will have had broken screens replaced through Applecare.
There, corrected that for you.
Re: Good riddance. @Crusty
Or perhaps I'm just too busy to care about the details when posting on a news forum. I'm still baffled by your aggression and name calling though if you are the grown up professional you claim to be.
Re: Good riddance. @Crusty
Sorry we have both and I chose the wrong one but well done on your Google-foo. I assume you're talking to me and just have some kind of dyslexia issue (or you're an asshole) because I couldn't see any users called Crusty who you'd be replying to.
Re: Good riddance. @rm
Most businesses YOU deal with may not care, but then they are being advised by someone who doesn't seem to understand these things himself so hardly surprising. ISO27001 is the international standard for quality control, I suggest you look it up after your GCSEs are over because real companies do care quite deeply about these things.
Office 365 is not being marketed in that way at all. If you want what you describe then Skydrive is what is being sold while Sharepoint even in the cloud is designed as a content control solution. Your disappointment in the product is entirely down to the implementations you have used. As with most things in IT, if implemented properly you'll find it works as advertised and can deliver significant business benefit even to smaller organisations. In IT, sadly, things are rarely implemented properly since we have no real way to eject the less useful members of the profession until the BCS pull their fingers out.
Re: Good riddance.
If you'd care to read the manual perhaps you wouldn't call it sharepointless. It's not a web based file server but a document control and management solution. It needs setting up for your document flow and control and is designed around scenarios such as ISO27001 or project management at which it can excel if the person who implements it knows more about IT and business than just fixing servers.
Re: Good riddance.
Blimey, someone left you in charge even though you can't spell Windows and couldn't work out how to support Hyper-v with a reliable patch testing routine? Hopefully you've stopped giving our profession a bad name now and have moved on to some kind of open source position to help the Windows cause even more.
Watch out for HP's low power claims, they always said that for their blade chassis too but using their own tools it turns out the blades use more power than similar rack systems.
"why keep showing them to me."
Because something about your profile is telling them that gambling ads are appropriate for you. I've never seen a single gambling ad on my profile, and dating ads only show up when I'm single. Even when I'm dating and have yet to change my status to being in a relationship they don't show me dating ads. Presumably they see the pictures and posts about a girl. Of course, I'm not cool enough to leave my profile blank and let them wildly guess what I like either. I filled in my profile and chat with friends and acquaintances on there about things that matter to me so they have a little more to go on.
Re: Bad investment opportunity
Yup, that must be right. After all, Microsoft and Apple have always been famous for dividends too. FB, like Google will only grow ad revenue as advertisers catch on to the new and better ways of advertising. They made over a billion dollars a year for the first couple of years after they floated, how is your company doing? Oh, you're not as smart as Zuck after all?
"a few recent studies and experiments have shown Facebook, gives no returns to the advertiser?"
What are you babbling about? The return for the advertiser is advertising. Facebook ads are some of the most effective advertising available and has Google wishing it could target so effectively. With Google, you search for a mountain bike and you get cycling ads until you search for something else. With Facebook, you mention 5 or 6 hobbies, tell them your age, sex, location and who your peers are and they serve you up things which may be of interest. They can even tell roughly what income bracket you fit into based on your posts. So now an advertiser doesn't need to show a million people an advert to make a sale, they show 30 people the ad because they know those 30 people are interested already. It's like a psychic Yellow Pages which doesn't need you to ask.
Obviously Facebook also offers passive ads for when there are no specific targeted ones to show you, and these are for brand recognition like Microsoft or Coca-Cola where they are not necessarily trying to sell you something, they just want to make sure that when you buy it's their name on your lips. Passive ads are orders of magnitude cheaper than targeted ones on Facebook. I believe when I looked it was about 1000 times cheaper per impression than targeting.
"because FLOSS is always chasing MS' own ever-changing file formats."
ever changing extremely well documented open file formats you mean? The ones which are "ever changing" every 2-3 years when a new version is released?
As opposed to the open source formats which seem to have changed on a very similar schedule according to wikipedia.
"Yes but you don't need Adobe to read PDF."
And what happened the first time MS tried to write PDFs from Office? Adobe said no and it was pulled last minute. I think you'll find that editing PDFs is still fairly limited because of this sort of behaviour which is probably what leads to the nonsense of PDF being a read only format in the article. It's no more read only than a Word doc file, it's just that the software to modify them is rare as rocking horse poo because Adobe are ass-hats.
"I'm puzzled by the babble about in-browser editing is preferred as if this is intrinsically connected to openness. Is this some Google infiltration trying to push Google Docs, or something?"
It's clearly government speak for some dodgy deal about to happen. It might be that they are about to renew the MS SA or that Google helped them write this. Even more clear since they chose PDF as the "non editable" format after all the BS about open standards and preventing lock in despite Adobes history with PDF.
