A SATA-compatible storage controller that can be configured to allow computers assigned to multiple different computer domains connected by at least one switch fabric to share resources of a common set of storage devices. The compositions are especially suitable for topical ophthalmic administration. The combination of a core, preferably soft core, with a thick, relatively hard multi-layer cover results in a ball having better distance than conventional golf balls having a comparable coefficient of restitution. A steam injection apparatus may be in communication with the interior of the reservoir device to inject steam into the interior to heat fluid located in the interior of the reservoir. Each IO device has an interface for communicatively linking the IO device with the bus, and includes a device processor which, upon detection of a potential IO device fault, severs the communication link provided by the interface with the bus to thereby remove the IO device from the bus and to prevent the IO device from keeping other IO devices on the bus from communicating over the bus. A control system is provided for managing power production and energy storage to maintain continuity of environmental conditions.
