[Server-devel] [XSCE] Re: Cubox Solidrun Prototype Packaging

this is a nice idea.  the input says 5V 1A max and we want to supply 5V 2A for 7.5 hours.  does this mean we need another 15 hrs for charging?  how do we supply the 5V input, from AC or 12V.

of course it would be nice if we could sense the charge level in the charger device and shutdown when it is low.  I know that is one of George’s pet projects.

are there low power states we can put the drive (spin down) and the cubox (sleep) into?

A quick look on NewEgg and this looks just about perfect.

1 5volt 2.1 amp output for the cubox-i and then a second 1amp 5volt output for the drive.  

Or for super large

That is a 15000mAh battery.  

That means that we can run at 2 amps for about 7.5 hours on battery.  Not too bad.

  All we need is 5volt DC in, preferably 2amps minimum.  If the drives aren't too power hungry then they should be able to be powered by the eSATAp connector, although I haven't tested that.  I will actually ask Rabeeh if he has tested it.  I know he has tested eSATA just don't know if it was self powered.  If we can't get eSATA to power the drive for whatever reason then a USB port should be possible.  A lot of older eSATA cases would require a usb plug for power, if they didn't support eSATAp. 

  Most of this depends on the draw of the drives.  If we want a battery backup solution then we probably want the larger case I posted a link to earlier and then a battery solution that provides two 5volt 2amp outputs.  I am pretty sure I saw one on Amazon.

  Do you guys have the models of drives you plan on using for storage?  Time to run some numbers.
