Redundant array of independent disk (RAID) controlled semiconductor storage device (SSD)-based system having a high-speed non-volatile host interface

摘要

Embodiments of the invention provide a RAID controlled SSD-based system having a high-speed, non-volatile host interface. Specifically, in a typical embodiment, a RAID-controlled device is provided that comprises a high-speed host interface that is coupled to a redundant array of independent disks (RAID) controller. The RAID controller itself is coupled to a set of controlled memory units that each comprises: a main controller coupled to cache memory; and a set of SSD memory units (each having a set of blocks of memory) coupled to the main controller.

1. A redundant array of independent disks (RAID) controlled semiconductor storage device (SSD)-based system, comprising: a high-speed, non-volatile host interface; a RAID controller coupled to the high-speed, non-volatile host interface; and a set of memory units coupled to the RAID controller, each of the set of memory units comprising a main controller coupled to the RAID controller, a SSD memory disk unit coupled to the main controller, and a cache memory unit coupled to the main controller such that hit ratios are increased; wherein the RAID controller comprises a disk mount coupled to the set of memory units and a disk monitoring unit coupled to the disk mount such that the set of memory units is mounted on the disk mount and is detected and monitored by the disk monitoring unit, and a disk plug and play controller coupled to the disk monitoring unit and the disk mount for controlling the disk mount; and wherein the disk monitoring unit is directly connected with the disk mount, the disk plug and play controller, the high-speed host interface, and a disk controller that is connected with a first host interface, respectively.
