Embodiments of the present invention are directed to systems and methods of controlling data transfer between a host system and a plurality of storage devices. One embodiment is directed to a virtualization controller for controlling data transfer between a host system and a plurality of storage devices. The virtualization controller comprises a plurality of first ports for connection with the plurality of storage devices each having a storage area to store data; a second port for connection with the host system; a processor; and a memory configured to store volume mapping information which correlates first identification information used by the host system to access a first storage area in one of the storage devices, with second identification information for identifying the first storage area, the correlation being used by the processor to access the first storage area. When data stored in the first storage area is transferred to a second storage area in one of the storage devices, the processor correlates the first identification information with a third identification information for identifying the second storage area and registers the first identification information and the third identification information in the volume mapping information.

Aqueous dispersions including at least one thermoplastic resin; at least one dispersing agent; and water; wherein the dispersion has a pH of less than 12 are disclosed along with dispersions including at least one thermoplastic resin; at least one dispersing agent; and water wherein the dispersion has a volume average particle size of less than about 5 μm. Some dispersions include less than about 4 percent by weight of the dispersing agent based on the weight of the thermoplastic resin. Other dispersions include at least one propylene-rich alpha-olefin interpolymer; at least one dispersing agent; and water. Methods of making such dispersions are also described.

Aqueous dispersion, its production method, and its use

This invention relates to an adhesive composition comprising a functionalized random propylene polymer (FRPP) having at least 0.1 wt% of a functional group, a heat of fusion of between 0.5 and 70 J/g, and an mm triad tacticity index of at least 75%, where the adhesive has a T-Peel adhesion on a polar substrate at 20°C of at least 175 N/m (1 lb/in) and a T-Peel adhesion on a non-polar substrate at 20°C of at least 175 N/m (1 lb/in) where the polarity of the polar substrate is at least 0.10 units higher than the polarity of the non-polar substrate. Methods to produce the adhesive and articles comprising the adhesive are also disclosed.
