I certainly wouldn't go with 3Par for a 250 user implementation. Something like Purestorage, Equallogic SSD or Atlantis would be more in line with that size solution, and even those are stretching it a bit.

The difference is that disk doesn't need a meat bag to load and change tapes slowly over a period of months, the data on disks is all online which is where the cost savings come from. As long as power requirements don't outweigh that cost then disk is starting to be the winner until you get to the extremely large capacities of systems like the LHC.

recyclling in this instance means rewriting to the same tape every 5 years rather than replacing the tape. If the data is valuable enough to archive this is a necessary step. Disk can do this online as part of normal maintenance.

Any chance of seeing tests with full size IOs? Modern Windows uses 8KB by default, and you ought to get a bit more throughput by increasing them. Given what you'd need the throughput for (video editing for instance), larger IOs make more sense anyway. I would expect this drive to be able to saturate the SATA connector.

EDIT - sorry hadn't noticed the ATTO pic. A little disappointing for flash performance to not be able to saturate a SATA link.

Re: Does your software require Windows? @lusty

Sorry Roland, I didn't mean that in a bad way, just that you were saying IBM had better support while also saying you'd not used the MS equivalent. I can fully believe they have great support, but I know from experience that it's not better than MS.

My statement asking for commercially supported OSs still stands - you pointed out a currently supported OS which was not available when 2003 was released and this is equivalent to Server 2012 being supported. As you said, the workloads are supported but the old OS is not, and that is identical to the MS policy which people here are bashing despite 2003 being one of the longest supported OS versions of all time from any vendor.

Re: Does your software require Windows?

"Oh, it's you. Hello shill. Kindly stop spreading incorrect information."

ANONYMOUS, please point us to your sources showing well conducted tests to back this up. I have personally run benchmarks with various hypervisors and have found that the MS one perfumes generally better due to superior driver support which allows it to get more from the hardware. Linux drivers tend to work but often lack the enhancements to really drive the hardware features.

Re: Does your software require Windows? @lusty

"I've not had the the same conversation with MS."

Perhaps you should try before commenting then. Microsoft spend enormous effort working with customers on this, and have architected it into the OS as well. Occasionally apps do something which blocks them from working but usually there is a way. In either case, third party software is ultimately out of the hands of your OS vendor and there is only so far they can go to help. In this respect, IBM and Microsoft are pretty much the same.

" IBM do fully support you running your 5L workloads on AIX 7.2L ..."

Microsoft fully support running Windows 3.x workloads on Windows Server 2012. That's not a guarantee they will work, just that the OS won't be hosed by the attempt, same as IBM are saying. Whoever supports the workload is responsible for making it work...

Re: Does your software require Windows?

"If you aren't running something wedded to Windows (e.g. SQL Server) then now would be a good time to consider using an alternative."

Point me to one alternative system released before 2003 which is still commercially supported and I'll consider it. RHEL 2.1 support ended in 2009 and 3 this year so with Red Hat I'd have had 2 extra migrations so far.

SLES 8 doesn't appear to be supported so that would need to have been upgraded already.

Ubuntu didn't exist back then and their oldest product currently under support wasn't released for another 7 years in 2010, meaning several upgrade cycles would have been required by now.

Re: Virtualisation

The quoted number of systems out there in the article is based on 2013 server sales. Given that 99% of 2013 server sales will be virtualisation hosts and 2003 era systems would not be I'd say there is potential for at least 10 times that number!

Re: What story?

"As I recall it, that story was about a DEC VAX/VMS machine. Unlike modern stuff, they did not need patching every week."

As I recall, Windows didn't need patching every week back then either. The patches are a response to bugs which have been found - the Internet has meant that more bugs get found in the more popular operating systems. This has literally nothing to do with code quality, and when the NT code was leaked the majority of coders actually credited MS with having very good code.

Re: Yup, as usual Apple were first with an earth-shattering innovation.

"Also, you realise that "clock speed, memory, megapixels and pixel density" are where "functionality and usefulness" come from, don't you? "

no they don't. Functionality and usefulness come from imagining a use-case for the device. Clock speed, memory etc. are enablers of these ideas, and occasionally more are necessary to implement the new use-case or to speed up poor user experience. If the user experience isn't currently crappy and slow then benchmark figures like these can be left alone and other areas improved with the exception of where new functionality requires a boost. Beyond retina type resolutions there is little benefit to more dots since almost nobody can see the difference. Beyond about 5MP a small camera sensor actually starts to produce worse pictures (for Physics reasons). Phone storage doesn't need to be large enough to hold every bit of data you have, as long as that data is easily accessible (cloud for instance). As long as functionality is improving then these other things are nice, but usually other areas are not improving and phone manufacturers are relying on benchmarks to sell new phones which are needlessly faster. Perhaps I'm wrong and more performance is required but I've not had a slow phone for a good 6 years.

Re: Pixel wars

" If I want to Bluetooth a file to a PC"

If I want to send a file to my PC I use one of the many, many better solutions than Bluetooth. iPhone was designed as a well connected device where email and cloud technologies were given priority. In fact whenever I've needed a picture from my phone I just go to iCloud.com and download a copy from there, no transfer required from the phone because it's already been done. Well done you for thinking of something the iPhone can't do, but the example I gave was one where the only alternative open to many Android phones is to replace the phone. The purpose of a designer was traditionally to determine useful features and to leave everything else out, and it seems only Apple are willing to leave things out on purpose while any feature lacking in the Android world is on the to-do list regardless of it's merit.

Re: Pixel wars

There are not loads more since that's the list of approved devices. My point was that this adds functionality while increasing pixel density just to make a number larger adds very little to the user experience. If you read back you'll notice that I did point out NFC was added to Android first and is still not in the iPhone. I also pointed out that unlike Bluetooth which has a huge list of uses people are asking for, NFC has yet to deliver a useful function. I'm sure Android itself adds great new features but the device manufacturers in that ecosystem choose to compete on pointless metrics and benchmarks rather than functionality and user requirements. It's nice that the Galaxy s5 and HTC one mate are twice as fast as last years models but as a user who wasn't experiencing performance issues last year and still not it won't change anything in my life. I used Bluetooth LE as an example because using heart monitors and other sensors through a phone does change my life, as did the camera improvements other than pixel count.

Re: Pixel wars

New phones from a shop? Perhaps it's now changed but a month or two ago several vendors specifically said only a couple of Samsung handsets were supported. Perhaps you could name a couple of phones which have full support for Bluetooth 4LE fitness profiles such as heart rate straps or cadence and speed sensors - the people making the sensors don't seem to be able to when their potential customers ask, and you'd think they would be motivated to find a solution to sell products. Perhaps when you post you could use your user name rather than AC too to show a little confidence in your assertions?

Edit to add a link to http://www.bluetooth.com/Pages/Bluetooth-Smart-Devices-List.aspx which shows what devices have official support. There were more than I thought but considerably fewer than you suggest.

Re: Pixel wars

And which currently shipping phone models include that software without cocking about with them? When I said support, I meant the phone, as it comes from the manufacturer. Other vendors quite rightly won't support a phone you have put different software on, and hence it appears to only be Samsung at the moment (according to the bluetooth device makers) supported for the third party hardware using Bluetooth 4.

As an aside, the iPhone 4S had this at launch in October 2011. Ignoring proper support for a moment, your comment about Android 4.3 puts you at the very earliest in late July 2013, probably later by the time it's tested and integrated with actual available phones. In the mean time, all of the Android handsets got larger memory, multi core CPUs, more storage, more megapixels yet didn't get noticably faster or produce better pictures. The iPhone 4S in the meantime continued to have sufficient performance and a good enough retina quality screen and camera for the user base who to this day find the phone adequate while also including support for this new useful technology. Samsung also added the shiny shiny NFC which has yet to see a real world use-case.

All I'm saying is that upping numbers without a good reason to do so is pointless unless you're also adding the other technology people will find useful. As I said earlier, my preference is to have the two tone flash, scratch resistant lens, Bluetooth 4 support and other tech rather than a faster processor which I would rarely notice. I don't run benchmarking software on my phone though so you should feel free to choose the bigger numbers if that's your use-case.

Re: Pixel wars

"the view could also be taken that they simply rebadged the same tired old crap every year"

But they didn't. Just because you are unaware of the changes doesn't mean there weren't any. As I have said twice, they added Bluetooth 4LE support which still isn't in stock Android and only Samsung support and only on 2-3 of their high end models. There are various other improvements they made such as the two tone flash and saphire lens which also fixed genuine problems and which have also not been adopted by other manufacturers. They also added the thumb scanner which is now being badly copied by others. Each of these is a minor improvement, and not necessarily original but they did make a big difference to the usability and usefulness of the phone. My point was that other manufacturers increase clock speed, memory, megapixels and pixel density but the functionality and usefulness of the device has stayed pretty much static.

Re: Pixel wars

"you realize it was apple that started the whole pixels per inch thing right? "retina" displays?"

Yes I do realise that. My point though, was that Apple changed to Retina because there was a need to change from the blocky old resolutions to something smoother, they then left it alone albeit with screen size increasing a little. Contrast that with the other manufacturers who made the change and are now needlessly increasing the numbers again and again. As another poster said, camera sensors over 5MP don't offer anything in terms of image quality yet compact camera makers and phone manufacturers have been increasing those too. Apple in their defence held off the camera sensor until they had a lens able to make a difference and instead added genuinely useful things like Bluetooth 4 support.

Re: Pixel wars

Unfortunately this is the only way Samsung and the Android ecosystem compete. Apple and its fans are far less prone to the numbers (other than iPhone generations, where bigger is better!). Apple tend to only increase things when there is a genuine need or strong demand. An example is how long they held off increasing the screen sizes and memory. They worked out what you can store in 16GB or 32GB and decided it was generally unnecessary to go bigger, so instead put in proper Bluetooth 4 support on the iPhone 4S - something only 2-3 Android phones can do to this day despite their having bigger/better/more of the numbers people look at. As a consequence, there are loads of devices unsupported by most Android phone such as fitness sensors or home scales and people moaning on other vendors forums about lack of Android support.

Another good example is the camera - Apple ignored the megapixels and added a better flash, a better non scratch lens etc.

I agree that Apple should also be increasing the other numbers in what is a premium phone but if it's a choice between genuine enhancements and simple number boasts I'll take the functionality every time.

Re: Replaceable battery

Transistor radios didn't need the battery to be shaped around the other components in order to make them smaller. I've had various mobile phones since the mid 90s and I've never needed to replace a battery before I replaced the phone. Usually my mobiles stay with me for 2-3 years and then a family member uses them for a year or two. I've no idea what you're doing to your phone to break the battery but in normal use you should get at least 3 years out of it if not more. You're right, it would be slightly simpler to put a flap on the back, but then the iPhone would look just as cheap and plasticky as the competition. A trip to the store to swap out the battery every 4 years or so wouldn't be the end of the world for me even if I ever do need a battery change. Of course, it might just be that Apple uses better batteries in the first place so they are less likely to need replacing, I guess that might be why our experience differs?

I'm curious though Boltar how many times have you personally replaced the battery on your phone? I rather suspect it's none but you'll probably post 5 or 6 on here to try and make your pointless point.

Re: Replaceable battery

"An easily replaceable battery would be a big step forward."

It's not difficult to change the battery, you just like to think it is. There is a simple link and pricing on the Apple website which explains everything.

"And easy replacement would extend handset life."

No it wouldn't. Handset life has nothing to do with battery life. Handsets are thrown away either at the end of a contract or when they are destroyed as a general rule. I have an iPhone 4s which still lasts 2 days on a charge which was bought on launch day, and my old 3GS was still going a year ago until my little brother smashed it.

The real question being ignored by el Reg is how recyclable is a Samsung handset? We can be certain that all handsets will be discarded at some point, and Apple using highly recyclable components is to be applauded. As has been said many times on these forums, the now common industry practice of gluing together is to allow easy recycling - serviceability works against this unfortunately and ultimately is worse for the environment.

Re: Nice improvement, but ...

I agree it's a nice to have, but having one or two larger boxes increases the cost significantly more than just buying the hardware. The people swapping out components will have instruction sheets for example on the standard model in their floors of the data centre (or in their "appliances" in the Azure cloud). New spares would need adding to the stores, possibly then requiring a new store. New drivers, firmware and images would also be needed. I'd have thought each model introduced globally will cost many millions in total, making it hard to justify on the off chance someone will require a large vm or two.

Re: Nice improvement, but ...

"Dell sell a machine with 6TB of RAM, why can you only rent one with a 24th of that?"

Simple economics. Almost nobody needs a machine that size, and those who genuinely do probably don't want it in the cloud. Those same people who need that memory footprint will also be spending most of their time trying to distribute the workload to avoid a bottleneck too.

It's cheaper for a cloud provider to buy commodity parts, so probably 2 socket boxes and even then they probably only fill them to 512GB memory because that's about as high as the vCPU/pCPU ratio will allow them to push in normal workloads.

Cloud isn't about what's possible, it's about mass production. Ford don't make a car that can beat a McLaren but McLaren cars are desirable by a few and affordable by fewer. Ford could probably make something to compete but it's not their business model.

Re: RAID

The problem here is that you'd then need to transfer the data over Ethernet or more likely the WAN which would take even longer. If your second NAS is local then there is far more benefit to be had with RAID 60 than with RAID 51 (effectively what you suggested with rsync). Realistically you'd need to do some maths to work out how long each recovery will take but once NAS 1 fails you'd be right back in the situation of having a RAID 5 array waiting to die - almost certainly using disks from the same batch as the failed ones, and Google's study into disk failures suggested that batch number was a bigger influence on failure than heat, humidity, vibration, or any other traditional ally recognised cause of failure, with those others being statistically insignificant.
