that array is a POS. Changing failed drives in that would be a major pain in the ass… and the way it doesn’t disapate heat, those drives probably failed pretty regularly.
JBODS like those are actually pretty common in data centers though and are popular with cold storage configs that don’t keep drives spun up unless needed.
For the cooling, they usually use the pressure gradient between what’re called cold and hot aisles to force air through the server racks. The pressure also tends to be strong enough that passive cooling can be used and any fans on the hardware would be more used to just direct the airflow.
If you’re paying per U of rack space for colocation then maximizing the storage density is going to be a bigger priority than ease of maintenance, especially since there should be multiple layers of redundancy involved here.
you still have to replace failed drives, this design is poor.
I work in a datacenter that has many drive arrays, my main storage space direct array has 900TB with redundancy. I have been pulling old arrays out and even some of the older ones are better then this if they have front loading drives cages.
there is no airflow gaps in that thing… I bet the heat it generates is massive

They probably wait for like 20%of the drives in an array to fail before taking it offline and swapping them all out.
Also, this doesn’t sound like the architects problem, sounds like the techs problem 🤷
I work in a datacenter as the system admin and waiting after one drive fails for a second to fail is asking for disaster
