Here is a Glacier S3 rack:
3 x Servers
2 x 4U Jbod per server that contains around 90 disks or so
Disks are WD Green 4TB.
Roughly 2 PB of raw disk capacity per rack
The magic as with all AWS stuff is in the software.
I worked in AWS. OP flatters AWS arguing that they take
care to make money and assuming that they are developing
advanced technologies. That't not working as Amazon.
Glacier is S3, with the added code to S3 that waits. That
is all that needed to do. Second or third iteration could
be something else. But this is what the glacier is now.
It all makes sense.
