Abstract: An embodiment of the invention provides a method comprising: permitting an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device. The cache comprises a solid state device and the permanent storage device comprises a disk or a memory. In yet another embodiment of the invention, an apparatus comprises: a caching application program interface configured to permit an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device. A caching application program interface is configured to determine an input/output strategy to consume the data based on the distribution of the data.

Abstract: In an embodiment of the invention, an apparatus comprises: a hard disk drive input/output (HDD I/O) optimizer configured to receive a primary input/output (I/O) operation stream for a given cylinder in a permanent storage device, configured to schedule a secondary input/output (I/O) operation stream that is pending on the same given cylinder or that is pending on an adjacent cylinder that is adjacent to the given cylinder, and configured to allocate free space from the same given cylinder or from the adjacent cylinder for the secondary I/O operation stream that is pending.

Abstract: In an embodiment of the invention, an apparatus comprises: a physical server; a guest operating system (OS) instance that runs on the physical server; a cache communicatively coupled to the guest OS instance via the physical server and allocated the guest OS; a plurality of storage units; wherein the guest OS instance is configured to access data in the plurality of storage units via a network; and wherein the cache is configured to boost a performance of a guest OS machine of the guest OS instance. In another embodiment of the invention, a method comprises: accessing, by a guest operating system (OS) instance, data in a plurality of storage units via a network; and boosting, by a cache, a performance of a guest OS of the guest OS instance.
