Comments on: Predictions for 2008: A massive data meltdown

You think the theft of a laptop with credit card numbers is bad? You haven't seen anything yet, say Sun executives.

This is the only way

Corporations dont think in terms of right and wrong, or what is pro-consumer, but in terms of risk and liability.

If there is actual or percived risk or liability pertaining to data theft, maybe corps wont keep our our personal info, SSN, DOBs, search terms, buying habits, and mommies madien name on one flash drive on some IT dudes keychain.

Megawatt conversion ?

Could someone throw me a conversion for what we're talking about?

a 50 MW data center has ? Terabytes ?

MW Conversion

That means A LOT of 'puters working in one site. If you use a normal PC with a normal PSU like 500w, imagine the amount of servers and peripherals to reach a power consumption of 50 Mega Watts. Maybe is not the technical approach you expected, but simpler sometimes is better. I hope that helps. Good Day.

Conversion

1MW - 1 million watts, so 70MW is 70 million watts.

A typical 4 way system would likely have 2 1450W power supplies and a 2 way maybe 2 850W.

Do the math and that's alot of servers, but that's also not taking into account power requirements for environmental and lighting.

Depends...

A single HP DL-380 (dual chip, 8 HDD's internally, anywhere from 4 -32 GB of RAM) has a pair of 1000W dual-redundant power supplies built into it.

Nominally, it is built to only need one of the two (with the load balanced between them and a failed PSU causing the other to kick up to full wattage as backup). Long story short - this puppy can eat up to 1kW all by itself, and it only eats 2U of rack space (a typical full-sized rack has room for 48U).

Most datacenters charge by the kW/MW as part of their billing... (the other two factors are bandwidth and physical space used). It would take about 1,000 DL 380's to suck down a megawatt. However, we still haven't counted routers (you don't want to know what a Cisco 4k or 6k series switch, or a Quantum PX-series autoloader eats).

A typical datacenter has room for at least a couple of thousand devices, so 40-60 MW isn't all that unreasonable a figure nowadays for a larger one.

HTH,

"A massive data meltdown"; but...

... for forgetful words called - REDUNDANCY, FAIL-OVER, DISTRIBUTED COMPUTING... ya know, up and running; and, fighting back after a 9/11 style attack!

I wonder what will happen if worm will really hit computeres the next year.My name is John, and My site is http://geocities.com/whitejohn29
