For GPUs there have been requests to expose the hardware and topology information in a first class way, so that schedulers can consume it consistently. Uses cases have been: handling heterogenous gpu hardware, topology aware scheduling (critical for GPUs given NVLink vs PCI vs QPI communication path between GPUs). CPUs and disk have had similar requests.
I filed https://issues.apache.org/jira/browse/MESOS-7080 to express the need on the GPU side, feel free to file a ticket that captures the use cases you have for disks.
