The SuperMicro chassis for our storage server prototpe has arrived. The chassis is a SuperMicro SC846E16-R1200 providing dual 1200W PSUs, 24 hot-swap 3.5″ drive bays and a 4U SAS2 expander backplane. We will be putting 1TB 7200RPM disks in the prototype but it is good to know that the chassis allows us to opt for faster disks if required.
