An apparatus, system, and method are disclosed for managing physical regions in a solid-state storage device. The definition module defines a physical storage region on solid-state storage media of a solid-state storage device. The physical storage region includes a subset of total physical storage capacity on the solid-state storage media. The storage controller performs memory operations within the physical storage region such that the memory operations are bounded to the physical storage region. The implementation module implements the physical storage region definition with respect to the storage controller for the solid-state storage media.

In a system comprising a first subsystem having a first plurality of nodes connected through an interconnect providing unreliably delivery (URD) of packets and a second subsystem having a second plurality of nodes connected through a packet-based interconnect offering reliable delivery of packets, a method of communicating comprising the step of transporting in both the first and second subsystem, a common packet format. The URD and packet interconnects conform with a standard. The standard is Serial RapidIO. The first subsystem places a Serial RapidIO idle sequence after each packet. The first subsystem places the Serial RapidIO idle sequence after a Multicast Event Control Symbol (MECS).

An apparatus for guiding a moving, flexible, tensed casting belt on a continuous metal casting machine along a substantially oval path. The continuous metal casting machine having an entrance-end, an exit-end and a moving-mold casting region extending from the entrance-end to the exit-end. The apparatus includes a non-rotating fluid pillow structure at the entrance end of the machine. The fluid pillow structure supports the mold-width of the casting belt. The apparatus includes two narrow shoulder-pulleys at the entrance end of the casting machine which are adjacent to opposite sides of the entrance-end fluid-pillow structure. Each pulley supports a portion of the belt outside of the moving-mold casting region. Each pulley guides the belt around the fluid-pillow structure as the belt revolves along its substantially oval path. The apparatus also facilitates the sealing, controlled-venting and recovery of pressurized fluids used to levitate the belt about a fluid-pillow structure.

Steering, tensioning and driving a revolving metallic casting belt in continuous casting machines wherein the belt travels along a generally straight casting plane P. Two two-axis robotic mechanisms are positioned at opposite ends of an exit-pulley drum, each including a "floating" housing carrying a bearing rotatably supporting a journal at the respective drum end. A drive shaft connected to one of the journals rotates the drum for revolving the belt. The robotic mechanisms adjustably position opposite ends of a rotating drum in X--X plane parallel with plane P for tensioning the belt and in Y--Y plane perpendicular to plane P for steering the revolving belt. These robotic mechanisms are controlled to operate in any of several modes: (1) "Walking-tilt" steering keeps the belt much closer to an exiting product than prior art, the belt being flatter and in better contact with the product for improving casting speed and quality. Mode (2) provides a "virtual squaring shaft" causing a drum to simulate being constrained by a rigid mechanical squaring shaft for synchronizing downstream movements of both drum ends for regularizing tension fully across a "cylindrical" casting belt. In modes (3), (4) and (5) the rigidity of the virtual squaring shaft may be "softened," or re-zeroed or eliminated, to accommodate small "frustro-conical" errors in belt manufacture. Moreover, even a small error in built-in length dimensions of a belt carriage may effectively be canceled by mode adjustments which effectively "twist" the virtual squaring shaft.

Continuous casting methods are described wherein the temperature of the flexible casting belts in twin-belt machines having two or more main rolls in each belt carriage is controllably elevated prior to contact with the molten metal to improve the casting conditions and the operation of the thin flexible casting belts; the temperature elevation preferably being relatively gradual may be carried out while the travelling belts are approaching the nip rolls or while the belts are in contact with the nip rolls, or both. Zone control of belt pre-heating is disclosed, and control of the coolant streams issuing from the curved nip roll tubes by use of fingernail-like extenders may be provided to aid in pre-heating the belts and in controlling their operation. Intensive infra-red heaters are shown directed at close range toward the casting surfaces of the belts, these heaters serving also to cure and dry any coating material on the belts. Heating by means of hot fluid, such as steam, is described, with the hot fluid being directed into the deep grooves in the nip roll beneath the rear surfaces of the casting belts. Mechanical and thermal sensors may be employed to sense the distortion of the belts and to measure their operating temperatures, these sensors being shown with automatic control of the belt pre-heating action. The methods of the invention can be applied to twin-belt casting machines regardless of whether the molten metal is supplied by open pool, closed pool or injection feeding.
