The only way in which to do this is to utilize shared storage. The trade off with that is significantly reduced disk performance in terms of both latency and, usually, IOPs. We are considering adding the option to use Storm Block Storage as a backing volume for instances rather than local storage, however this will result in poorer disk performance than utilizing local storage for most use cases.

Unfortunately this is an area where the utility varies greatly from person to person. The current implementation was chosen as it actually shows the critical RAM needed by the system allowing the administrator to see at a glance whether or not their system is becoming memory bound without including items such as caching and buffers which can confuse the issue. While we do understand the other view also has uses, many customers, and administrators, appreciate being able to see at a glance if their system is approaching the point at which their workloads are becoming unable to run efficiently with the resources currently on the system.
