Web Servers Getting Naked, For Weight Savings 101

from the community-standards dept.
1sockchuck writes "Cloud computing is causing servers to get naked. HP today announced a 'skinless' server optimized for customers packing thousands of servers into cloud or HPC environments. This follow the lead of SGI/Rackable, which ditched the cover when it introduced bare bones servers for its CloudRack (previously discussed here). HP says the skinless design makes servers far lighter, which is apparently an issue when shipping them by the rackload."

    This makes sense, since the dust should already be filtered, which removes a large part of the need for a case. However, I do wonder about the airflow, since an ordinary case helps to direct the airflow through the kit rather than over the top, which might be a problem. On the other hand, without a case, the ventilation will be much better, so what is lost on the swings may be gained on the roundabouts.

    This is a nice idea though, and would make sense for rackmount routers/switches, since these usually sit in an enclosed cupboard anyway.

      Given the fact that there don't seem to be any fans pictured in the chassis itself, and given that this is targeted at very large scale customers, I'd assume that the use case for these things is "inside a specially designed rack with power and cooling, with that specially designed rack completely full" which would allow the OEM to just validate against that case.

      If you just put one of these on a table, it'd probably overheat; but, if you want to do that, HP wants to sell you a pedestal server instead.

          You might want to RTFA a little more closely: The fans in the second picture are embedded in a larger chassis, into which the module in the first picture is inserted. There are no fans in the server modules. There are fans, and power, provided by the larger enclosure into which they are inserted. I was wrong to speculate that it was full rack(the z6000 enclosure is only 2u, for reasons I can't quite fathom); but the thermal performance of the bare server does, indeed, depend quite closely on the enclosure into which it is inserted, just as I speculated.
          • Additionally, fans without some kind of enclosure wouldn't provided for proper airflow. AMD's and Intel's system design recommendations both state that a proper enclosure is necessary and even give details as to how that closure should work with regard to airflow.

      A mechanic was removing a cylinder-head from the motor of a Harley motorcycle when he spotted a well-known cardiologist in his shop. The cardiologist was there waiting for the service manager to come take a look at his bike when the mechanic shouted across the garage "Hey Doc, want to take a look at this?"

      The cardiologist walked over to where the mechanic was working on the motorcycle. The mechanic straightened up, wiped his hands on a rag and said, "So Doc, look at this engine. I open its heart, take the valves out, repair any damage, and then put them back in, and when I finish, it works just like new. So how come I make $25,000 a year and you get $160,000 when you and I are doing basically the same work?"

An external skin (i.e. case) can act as a sort of fan shroud to direct air over certain components within the chassis or force a general flow of air through the enclosed space that might not be as efficient or effective without the shrouding provided by the enclosing case.

These "naked" computers are nothing more than a pair of dual-proc computers, in a 1U-ish chassis without a lid, which needs to slide into the appropriate rack-mounted housing in order to work. This housing includes all of the cooling and power supply goodness one would expect, and (of course) includes a top panel to promote useful airflow and limit RFI.
