摘要： Disclosed is a storage virtualization subsystem (SVS) architecture comprising a plurality of SVSs, each SVS comprising at least one storage virtualization controller (SVC), and, in some cases, a physical storage disk (PSD) array attached to the SVC. A first and a second data access path is configured passing through the SVSs to form the SVS architecture such that when one path is failed, the other can be taken as a substitution. The SVSs in the first path are connected in a first sequence and the SVSs in the second path are connected in a second sequence different from the first one. In another embodiment, each SVS comprises a plurality of redundantly-configured SVCs rather than one SVC. The first path is formed passing through a first set of SVCs and the second path is formed passing through a different second set of SVCs.

摘要： An image transformation method to reduce the number of the gray levels is disclosed. Error diffusion, error bias and a programmable integer C are utilized. For the focus pixel, the value Gi of the original gray scale is read. The related errors Ej previously obtained from some chosen pixels are loaded in. The respective corresponding weighting coefficient Wj for each errors Ej are determined. Then, a resultant gray value Ri of the focus pixel is calculated by Ri=Gi+&Sgr;Wj(Ej−C), wherein C is a programmable integer. Thereafter, the gray value Ri is dividing into most significant part Mi and least significant part Li, wherein Mi is a K-bit integer, Li is an (N−K)-bit integer, Mi×2N−K+Li=Ri, and −2N−K/2≦Li

The JBOD subsystem contains at least one external JBOD emulation controller coupled to the host entity for emulating IO operations in response to the IO requests and a set of at least one physical storage device coupled to the JBOD emulation controller for providing storage to the host entity through the JBOD emulation controller.
