> Currently, the number of disks present on a node is not considered a factor while scheduling
containers on that node. Having large amount of memory on a node can lead to high number of
containers being launched on that node, all of which compete for I/O bandwidth. This multiplexing
of I/O across containers can lead to slower overall progress and sub-optimal resource utilization
as containers starved for I/O bandwidth hold on to other resources like cpu and memory. This
problem can be solved by considering disk as a resource and including it in deciding how many
containers can be concurrently run on a node.
