I can tell you I manage 2 data centres totalling 14,000 sq foot. first is 8k sqf and has 950kw, (completely utilised) and the second is 6k sq foot and has around 900kw (80% utilised).
I guess your figured are there or thereabouts.
This doesn't include cooling which is powered separately and managed by the host.
So i'g guess your figures are reasoably there or thereabouts. Worth noting that in our larger smaller DC, we have loads of power and no usable space, and in our bigger DC we have loads of usable space and no power.
its worth bearing in mind that although some devices are becoming more power efficient, the majority of kit is only ever utilised at 10% tops. so if all the kit was running full throttle, temperature might become an issue.
Alos, bear in mind that old, inefficent kit is still a bugger to remove when the unix guys love its reliability (i/m looking at you, RS/6000)
you including the Blizzard side, of Activision?
Re: Why is the Intel NUC passively cooled?
it isn't passively cooled
"Yet the NUC’s CPU is actively cooled: there’s a small fan unit venting out to the back of the box"
Re: Yet the NUC’s CPU is actively cooled
*IS* actively cooled. it has a fan. If only you hadn't stopped it would confirm:

Re: lovely, until the price
Maybe your work has the celeron barebones version which seems to retail for around £130 a pop?
quick google and look on the main retailers suggests the pricing is pretty similar around the £240-£250 mark

lovely, until the price
Decent size, reasonable spec. But whoa, the price man. £225 barebones? thats a big premium for a reasonably small box.
I had a PI running XMBC and now an ebay acer revo thin client doing the same thing (£40). Who would want to spent £300+ on this solely to stream media to the telly?
Nive to see some lower wattage gear becoming a bit more mainstream, but wheres the niche? teach a kid to code x86 on this, or get them an old celeron off ebay for a 10th of the price? its not going to replace a laptop, and isn't powerful enough to be my main rig.
I'm sure this has a place, i'm just not sure where. Shame as i like the idea.
Just realised, would be mighty handy if the tablet of choice could have a kensington lock slot.
got my figures wrong on option 2
the ebook is even more expensive, forgot to add the ebook licences
would be £273,000 over 10 years, or £27,300 p/a
£183,000 over 6 years, or £30,500 p/a
Re: Completely right on all accounts
There seems to be a few arguments here for using tablets / ereaders at textbook replacements. Seems a worthy idea in principle. As I child, I would much prefer walking a nexus to 5 textbooks a day a but I would love to know the figures on books costs vs ebook costs. The publishers make a *mint* on selling text books, often upwards of £30 a pop. University books even more of a killing. The print cost is bugger all of the sale price. I can’t see why they would cannibalise their own margins to sell ebooks cheaply. Its a pretty closed market too, not like another publisher has a volume of GCSE/ SATs accredited levels of study material.
Secondly, textbooks last ages. I’m sure we all remember getting a naff 20th hand textbook and looking in the front cover to see what student it was previously lent to. I started secondary school in 1994. I distinctly remember being given a text book that was printed in 1983, the year I was born. So that book lasted at least 11 years. That wasn’t unusual. You find me any tablet that’ll last typical kids usage for more than 2 years. I can’t see it. I‘m not arguing that we should never update teaching materials, but I’m not yet convinced an ebook is the answer to integrating tech into schools.
***The below numbers are estimates. If you know better, feel free to correct. I’d love to see some proper maths***
Lets say a small secondary school has 5 year groups, 2 classes per Year group (30 per class). Thats a total of 60 students per year, and 300 students in all. Each student needs 8 textbooks per year for a variety of subjects.
Working to the assumption that a text book costs £30 and an e version costs £20. (go on amazon, even chart retail books are usually barely discounted)
Also assuming the school avoids a £300 iPad and buys a £150 budget jobbie
School buys old style text book. Each book lasts a decade.
School buys £30 text book x 8 per student x 300 students = £72,000
Total cost of Paper text books is £72000. Lifespans of 10 years, Thats £7,200 per year.
Lets say the books only last 6 years, thats £12,000 per year
School buys cheap 10” tablet per student and 1e licence per student per subject. The e licence is permanent and therefore is transferrable to subsequent students.
Licence cost is £20 licence x 8 per student x 300 students = £48,000
Hardware cost is £150 per tablet x 300 students = £45000. Hardware lasts 2 years (MAX) so over a decade will need to buy 5 times = £225,000
Total cost of electronic text books is £225,000 over 10 years. Thats £22,500 per year.
Lets say the project lasts 6 years, Thats still £48000 in licences. Lets just argue they get a tablet to last 3 years, albeit unlikely. Thats 2 purchases = £90,000. So a total of £138,000 for a cost of £23,000 p/a
I’ve not even mentioned the cost of charging the devices. I agree it is unlikely to be huge, but equally, it is unlikely to be negligible. 300 tablets twice a week at £0.10 a time is still £3000+ a year. I guess its just the parents who will foot that.
Again, to add, I am happy to be corrected. I currently work in tech and have previously at a publisher of educational books though. A reasonable knowledge of the print industry.
I love tech, and it makes sense to integrate the next generation. I can’t help but get the feeling tablet tech is brought into schools for the kudos rather than any defined savings or advantages. Hubris.

Re: Another in the long lone of real iPhone killers.
i really don't wanna do the whole "my android is better than your iphone/BB/Winpho" but i can't help but agree with the above statement.
Bought a 16 gig nexus for for £279, comfortably cheaper than every similar device out there. the UI is excellent even for an android virgin. If price is a factor in your purchasing decision, you seriously need to give throught to the Nexus 4. The battery easily lasts a whole day of moderate use (whereas my i4S was dead by 4-5pm). It is light, has an excellent screen and and excellent range of apps. Managed to sell my i4S too which covered 90% of the purchase price.
well given you never got to play with the dell kit, here's my view.
I’m not sure what the C6220s is about. It is definitely better than the C6100 it replaced. They were a bitch to configure (10+ mins to boot to drac config mode drac per node = hours when you have 6 chassis to rig up) The C6100s i found poor MTBF issues as well, multiple motherboard swapouts particularly.
These (well the predecessor C6100) were designed by Dell at the behest of a rich client who wanted custom gear. The point being to squeeze as many nodes into a defined space as possible. I’ve never seen that these do that. You can get 16 blades into an M1000e encolosure, or 10u of space. I rack 3 chassis in a single 42u rack leaving 12u for airflow and patch panels. Thats a total of 48 servers in a single rack Cooling is never ever an issue on these, they have plenty of on board fans and even at the top of the rack they dont surpass about 30 degrees. However, the C6220s run much hotter. I had 10 of these in a dev rack recently (i.e. for a total of 40 nodes) , and the heat they were kicking out at the back of the reack was obscene. Alarming all over the shop, and anything above halfway up the rack was particularly bad. The only way we could get these running consistently was to place the kit in the first rack by the ACU so it gets more air than most racks.
Bear in mind as well that the Blade chassis includes (in my case) 4 ethernet switches and 2 San switches. Adding the equivalent switching in the rack is at least another 6-8u. Oh, and forgot to add there’s no sfp or san ports on the C6220s so they’re out of the question too.
obviously i cant compare on the Fat kit, but for our use, the 4nodes in a 2u space just doesn’t seem to do the job unless you have loads of cooling but not loads of space.
Re: Lies, Damn LIes etc
you, sir, shall have an upvote.
Speed up UK release schedules and avoid the exclusive licences and i’m a rehabilitated freetarder
I’ve been known to dabble. I must say generally I buy the dvd when its on offer, rip it and never open it again. However, some stuff the release schedules are awful.
Game of Thrones as an example, probably the best show (in my eyes) to come out of the US in a few years. Season 3 is a few weeks away from transmission, but Season 2 is only just out this week on DVD in the UK. HBO don’t licence to Netflix or Lovefilm so there was no other way to watch it.
I’d happily just got a netflix style subscription if only there was a greater range. It feels to me like i need netflix and lovefilm just to get about half the market.
it does mention battery life...
"Google is claiming a battery life of five hours for the unit."
that's pretty clear.
I look forward to seeing the review. seems pricey but the screen res is lovely. i guess i'll hold judgement for now.

Re: The Truth
This is really an article aimed at the slightly geeky looking to expand their knowledge but not really learn anything deep about linux
Thats probably me up there. Moving from the "geek by work" to "geek by choice". Would like to learn more about Linux. would happily learn something deep about linux, but would need to know my way around the environment first.
Don't feel any further enlightened after this article., Shame. i got excited when i read the title.
been out of stock again, but checked today and they're showing in stock and 1-2 week turnaround.
Placed my order before they disappear again!
Beware Finance industry figures!
As a contractor at a big bank, I would take the figures with a pinch of salt. My bank's IT is almost all outsourced, bar the desk monkeys. Every few years the bank decides that it has become over reliant on the contractors, hires a few middle men to "refresh the contractor pool" and manage these contractors. Inevitably the productivity halves overnight and then they have to take on a good few of the contractors they just got rid of.
So your advert for a Bank IT job might not be sector growth, so much as replacing staff (forced) turnover
What happened to the link to the Hardware site?
Anyone notice the hardware link has disappeared? Up in the top right there's a link to Whitepapers and the Channel, Hardware also used to be there.
Can i assume the separate hardware page is being phased out? Recent articles like
i would usually expect to see on the hardware page.
you can fanny around with home user channel all you want, but please stay the Fuck away from my poweredge.
Have a sibling working at HMV, poor chap. Jokes aside, the threat of redundancy is horrid. Best of luck to anyone out jobhunting.
I do think there is a place for a Retail CD / DVD on the High street. I just think they need to review their range. Drop the T-Shirts / Posters / Crap bog Books. Increase the back catalogue range.
Any planned purchases I do are online. I think if HMV offer the same Online range and pricing as Amazon et al, i'd happily shop there. (clearly, the in store range won't be as big, but definitely has room for improvement). In store purchases tend to be a lot more impulsive. I'll wander in for a mooch, then remember they only sell Beats Audio 'phones and Tulisa Contoshaglots albums. Then i'll wander back out.

Re: Acer W510
Just googled, you're talking about £500+ for one of those. I'm sure it is very nice indeed, but £500 buys a lot of laptop.
Half the allure of a netbook is they were usually decent value for money in an industry that often isn't.
Come back Netbook
Couldn’t agree more with most of this.
I wouldn’t be surprised if there’s a resurgence in Netbooks a few years down the line. Tablets are all well and good, they definitely have their place, but for so many applications, a keyboard and a few more ports is so mightily handy. Maybe a few years of people trying to do their accounts or proper photo editing on a tablet will remind them how handy a keyboard and trackpad can be. And I don’t need to worry about free disk space etc.
Just gotta hope my Acer Aspire does me until then.
Re: no rating?
We all know ratings are relative.
We all accept if a C64 was given 95% in 1983 then the rating isn’t true today.
We all know that nothing scores below 60%
We all know that Apple always gets the Apple 15% bonus (cue fanbois...)
I just think the rating is a reasonable indicator of the reviewer’s experience of the product. At least class it into something more subjective like BUY/Recommended/Avoid.
Its also a good talking point on the forums as to whether the score is merited etc.
My own preference would be for Reg to use the full range of ratings though. If a product isn’t fit for purpose it should be scoring considerably less than 60%, and manufacturers are still pumping out pointless shite – hence the plethora of 1366*768 kit being churned out.
Nice to see some actual hardware reviews again on the Hardware site. However, why the continuing trend for dropping The rating on the product. Its the go-to figure to see if you approve or not.
Is this for editorial reasons, or just to keep the manufacturers sweet? Or just to encourage us to click the amazon link even on crapware?
Re: So, nothing legal is getting close to ThePirateBay yet.
excellent. love the description for the queen!!
Why don't they ever compete on price?
I have a small amount of Juniper kit in my Data Centres, some 8200's and 4500s. Given their tiny market share against Cisco, I'm always bemused why they don't price more agressively. We're in the process of upgrading to 10gig and the price differential is no negligible that it's hard to persuade all the die hard Cisco lovers to try something new.
in what way is this ultra?
Shitty cpu (atom, serious!?)
shitty screen res
shitty port availability
must do better
ultra seems to just mean SSD now. i'm gonna fish out my Pentium2, whack in a £40 SSD and sell it as an ultra.
Re: The lack of Ethernet is a killer
If thats your opinion, I take it you feel you may as well just have one on board USB port and make anything run through a USB hub?
Personally, on a portable device I like it to be portable. The grief of having to carry unavoidable stuff (PSU/external HDD/optical drive/Mice, etc (delete as appropriate) doesn't need to be worsened, and the port is small and cheap enough that theres not a lot of reasoning to remove it.
So, yeah, your opinion may vary, but not having an on board eth is a factor in my decision to buy. Ethernet is a pretty standard medium in an office environment so i wouldn't want it as an extra.
Re: The lack of Ethernet is a killer
Carrying adapters everywhere kinda negates the point of having a portable device though.
No Eth, No HDMI, No sale
Fancy enough looking but these hybrids still feel like a jack of all trades gimmick.
No HDMI means no discerning media whore is gonna get it. And no ethernet port is gonna seriously affect its use as a business tool.
I'll have to stick to my £200 notebook for now...
long live the mouse
'cos all of this spaff is a stupid show off gimmick.
mind you, i'd love to see a "take your kinect to work" day. :D
There's loads of good ideas for its use in charitable environments, but even for free hardware, its the $2m a year running costs that blow it.
You got anywhere in mind for the place with plenty of solar energy? cos i'd love to the the solar panel rig that will support 861kw kit 24/7. The battery cost let alone the PV panels or the space needed etc...
Re: Home Use
yarp. i can agree there. I have a Dell T7400 Workstation with dual 3ghz quad cores and 64gig of ram. was a goodbye present from a previous company i worked for.
Complete overkill for most home use but flies though anything and I use it for the odd bit of CAD and messing around with VMware (shame the free one only supports 32gig) But the 1kw PSU kick out a right noise and a bit of a rattle. Which means I'm loathe to use it unless i have to.
As a buyer of switch gear in a data centre, i can attest to the "we like 10gig but we don't like 10gig prices" view.
A clumsy approach at the minute is teaming multiple gig connections and the switching is still the bottleneck in a lot of our vm arrays.
95% of my infrastructure is 1g switches. we'd love to upgrade the old distro / access layer 6500's but the capital outlay at the moment is crippling. Can't fault Cisco kit, but would like to see a bigger share for Juniper or any of the other minnows feeding the scraps. Hopefully this would lead to a bit of competition and a better deal for tech budgets.
Re: looks lovely. but keyboard is a no no
so you cant get a full sized bluetooth keyboard then?
I imagine if you're enough of a style slave to buy this then you wouldn't want a cable ruining the sleek look on your desk.
