Systems and methods provide a programmable or controllable infusate delivery with minimal power consumption using controllable valves and with safe and reliable operation of the delivery system. Embodiments provide programmable control without the need for implantable power sources using multi-stable valves and / or mono-stable valves which are powered externally when activated. Embodiments provide for very low power programmable control, such as by employing micro-electromechanical system valves and a flow restrictor array. An external program controller may be utilized to provide a user interface and which may communicate with the controllable infusate delivery system using wireless links. Internal controller circuitry may provide for flow control changes for different activities or times of day and / or in response to changes in pressure, temperature, etcetera. A safety valve configuration may be implemented which provides a safety flow valve configuration which responds in an opposite manner to particular events than does a corresponding primary flow valve.

An untrusted component exposing a high level storage object interface within an untrusted client virtual machine accepts application level storage object operations. Responsive to a storage object operation, the untrusted component passes a message through the underlying hypervisor to an associated trusted component. The trusted component processes the message by authenticating the client virtual machine and locating an internal mapping between the client virtual machine and an associated customer-specific set of backend storage resources to which the requested storage object operation is to be applied. The trusted component uses a trust relationship with the backend storage system to securely communicate the storage object operation to the backend storage system, and passes the operation results through the hypervisor back to the untrusted component in the source client virtual machine from which the storage object request originated.
