Oracle reveals 32-core, 10 BEEELLION-transistor SPARC M7

Joke

Though

that's assuming there's an entity on earth wealthly enough to licence 1,024 cores of Oracle Enterprise software with all the optional trimmings in the first place.

Dr Evil Ellison gets it for free obviously...

Cisco says network virtualisation won't pay off everywhere

Tokoloshe

Re: Cisco are probably right...for now at least.

FWIW, my future view of SDN is of a hardware independent, white-with-rainbows box networking utopia :)

I was questioning VMware's approach of NFV on x86 for east-west workloads, which looks great on a marketing slide, but would seem compromised by performance and/or cost, to my jaded, though admittedly myopic, eyes. To that end, and based on what *supported* SDN technology is available currently to the mere mortal sys admins, I would say that the article title is correct, but won't be continue to be so.

In summary, I don't think either VMware or Cisco's SDN land grab will succeed...both will get disrupted into IT history.

Cisco are probably right...for now at least.

Like any true commentard I haven't read the Cisco whitepaper, but having seen VMware's CTO present on NSX a couple of times recently, I do have reservations.

VMware would say that you simply move all your network workloads like firewalls onto NSX (so called NFV) and use cheaper 'white box' switches to tie it all together. Now some NSX supported virtualisation targets, Palo Alto Networks FWs for example, use expensive custom silicon like FPGAs (as well as x86 chips) in their appliances to deliver multi-gig FW/IPS throughput. The best that seems to be available in ESX/NSX for Palo Alto FWs is 1 gig FW with only 600Mbps of IPS, and that's using 4 cores.

In short, if Palo Alto, or for that matter, any vendor using non-x86 silicon, could do multi-gig or 10G firewalling, IPS etc on commodity x86, rather than presumably more expensive custom ASICs/FPGAs, then wouldn't they be doing it already*? How many x86 cores (and corresponding ESX and NSX licences) will need to be thrown at network services that non-x86 silicon can do better, and maybe more cheaply?

I don't care enough to do the maths...but there's presumably someone out there that has (thanks in advance!)

*Check Point are tied to x86 and that (plus a large dose of incumbent complacency) is why the FPGA-based PAN FWs have been kicking their arse over the last few years.

Re: FAB!

"The torus shaped building was called 'the roundhouse'. Quite what you use such an unusually shaped building for, I don't know."

The Fusion Reactor (probably).

Perhaps Musk's eggheads can get to work on that unsolved problem after completing the full set of TB craft.

Re: I'd like to see numbers on that.

According to TFA;

802.11ac?

No mention by Richard of .11n's successor, which among other things, substantially reduces device-side power requirements.

The IT industry doesn't do the looking back thing well, so there's unlikely to be much effort put in to making .11n more efficient when Cisco et al can sell you shiny new .11ac things.

Re: BYOD more like MDM

It's a fair point that MDM suppliers' focus on mobile operating systems (rather than all mobile devices including laptops) means that they don't yet cover the plethora of devices that could fall into the BYOD category.

From my contact with the main MDM vendors for a recent project, some support OS X (e.g. Mobile Iron and Airwatch), but in reality all of them are waiting for PC/Mobile OS 'convergence'. This has started wth Windows 8 ( I have to say 'started' due to the fundamental differences that remain among Win 8 Pro, RT and Phone variants) though presumably MS will get there in the end, with Win 9 probably. Re Apple, one vendor said that they expect iOS and OS X to fully merge in 18 months. I reckon they might run an iOS VM on OS X, though that would really require a touch screen on Macs and Tim Cook to remove and eat humble pie from his fridge-toaster.

Re: 100% availability?

Lots of service providers will give a contracted 100% SLA, but the penalty for it being breached is sometimes only a refund of the pro-rated service cost e.g. your £1m/yr cloud service is down an hour so you get £114.15 back.

First Samsung Galaxy S4 review leak: Stop FONDLING, start FINGERING

Something useful for those 8 cores

Samsung could get Folding@home ported, especially since Sony have ended support on the PS3. All that silicon could do some good overnight, after the phone has fully charged and is still connected to the mains.

New MPEG format paves the way for UHDTV

Tokoloshe

Re: Increase in spatial, but what about temporal?

Good point,

I'd prefer to get 1080p rather than 'i' from Sky HD right now so I can 'sweat' my current set, rather than upgrading to a 4k set which is similiarly hobbled by Sky's technology (possibly) and desire to dial down the bandwidth to support more channels (definitely)

Are Sky going to push a 4k signal for 3D at 1080P or another bunch of shopping channels?

Sky F1 channel 'free' for HD subscribers...

and as HD costs £10/mth, it's cheaper than buying the sports package either on its own (£20/mth) or in addition to Sky Movies (£12/mth).

It's worth mentioning that

The unmarked police vehicle was actually a lorry, though the police driving it were in uniform, and he failed a breath 'test' not 'text', though to be honest he would have failed anything breath related given the number of empty special brew cans in his cab.

I think he should have had his HGV licence revoked, livelihood or not.

Console Vs. PC

While I haven't been reading this nonsense as long as I've been playing computer games (since Blitz on the VIC20), it seems to have gathered some sort of assumed truth over the last decade or so.

The inevitable 'argument' is used: console shooters are easy because the controller makes them hard to play, hence everyone *must* be using auto-aim.

Very few games have auto-aim on by default (I always check) and it can also be turned off.

So as I play without auto-aim can I assume that you're the pussy for using a more accurate control system?

And what system do I play games on? All of them. So I can get on and enjoy playing whatever I want on any platform I want.

Costing everything in the real world

Actually you describe the non-accountant approach, as accountants (and more business minded IT professionals) are aware of the concept of marginal cost.

Graphing server costs against DC capacity would demonstrate the rather obvious spike in the cost of the server that exceeds the datacentre space (the marginal cost will equal the server + another datacentre, or perhaps more 'real world', the cost to host it elsewhere). It's high marginal costs like this that are front and centre when decisions on IT strategy are made.

Also, it's odd that you focus on what are long term capital costs that tend to be depreciated over a long period (whatever the useful life of a DC is), rather than the costs that are more directly affected by the server population, like power and server hardware maintenance. Even a DC's equipment (a/c, fire suppression, power generation/backup etc) will usually last 5-7 years, so through a server refresh.
