back to article Dell lends Apache ARM software efforts a hand

The hardware engineers at Dell's Data Center Solutions custom server unit have bent some metal around Calxeda's EnergyCore ARM server processors and donated a box to the Apache Software Foundation so it can tweak and tune the Apache web server as well as the Hadoop data munching stack and the Cassandra NoSQL data store to run on …

Why wait 'til Windows Server 2012 R2

The Windows Server 2012 kernel is shared with Windows-8 which has already been ported to ARM.. I'd be pretty sure that Dell & HP have a skunkworks Windows Server build for testing

Rumor is Microsoft explicitly said 2012 (R1) would not be ported to ARM. Since it has not been ruled out (yet) for 2012 R2 the hope is it might show up then.

Fascinating article and really shows how much datacentres have changed over the last decade or so. Great to see ARM instrumental in this change too - I just hope they continue to take on Intel and AMD and don't sell out.

The Copper server is based on the 3U C5000 server sled enclosure, and each Copper sled has room for a dozen sleds.

That sentence makes no sense. Do you mean each copper server has room for a dozen sleds?

Nope. It was supposed to say "each Copper enclosure has room for a dozen sleds." Apologies.

Dell has a higher density per rack U than HP

One correction is needed from the author of this article. The SL6500 chassis from HP is 4U in height and this means a density of 72 servers per rack unit, as it is written in this previous article on the Redstone servers http://www.theregister.co.uk/2011/11/01/hp_redstone_calxeda_servers/ . This means Dell achieves a much higher density with 90 servers per rack unit. The article presents HP as having the greatest density. You should revise the article and insert the corrected information.

Re: Dell has a higher density per rack U than HP

Absolutely correct. Read my own story wrong as noted elsewhere. Dell has the advantage density wise, packing 5 sleds in 4Us compared to HP's 4 sleds in 4Us

That's 25% more density than HP Redstone, not just "a little" more :).
