Some requests for the DropBox Diskotech tech blog series: For which datacenter cooling system are the Diskotech storage pods designed? Hot aisle cold aisle? How evenly can the disks inside the Diskotech be cooled? With this question I try to ask, how good is it in keeping all drives cool? For example for the theoretical case where all disks in the Diskotech are dissipating identical heat, how much variation is there in drive temperature at roughly 25ºC intake temperature? How much power is consumed for cooling (despite that it will be fractionally low compared to what the disks will consume)? Is there any drive idle optimization done or is the expectance that not any disk will reach its idle (non-rotating) state ever? Is there any optimization done inside a Diskotech to reduce the (inrush) current surge when connecting the machine to power?
