Abstract
The invention discloses a method for achieving soft redundant array of independent disc (RAID) redundancy and a microcomputer system of the method. The method comprises the following steps: partitioning a system hard disc of the microcomputer system, correspondingly partitioning a redundant hard disc according to the partitioning of the system hard disc, and performing mirror image matching on the portioning of the system hard disc and the partitioning of the redundant hard disc. By partitioning the system hard disc and the redundant hard disc, redundancy of the microcomputer system is achieved through relatively small number of hardware equipment under the condition that few personnel are engaged, and the cost of system redundancy is effectively lowered. Furthermore, by partitioning a first storage hard disc, a system start up directory file is acquired to perform redundancy, and the stability of the performance of the microcomputer system is further improved.
Description
Technical field
The present invention relates to minicomputer field, espespecially a kind of method and minicomputer system thereof that realizes the many redundancies of flexible plastic disc array (RAID).
Background technology
Disk array (Redundant Array of Independent Disks is called for short RAID), be a kind of polylith independently disk (physical hard disk) by array mode, combine and form a disk group, to provide than the technology of the higher memory property of single disk and data redundancy.By using RAID can preserve very easily mass data on hard disk.RAID forms a large capacity virtual memory facilities some low capacity physical disks, can improve physical store efficiency (being data read/write) or strengthen by redundancy (identical data being stored in to the method for the different local redundancy of a plurality of hard disks) safety that data are stored.
RAID is divided into hardware RAID and software RAID in actual applications.Hardware RAID by RAID card by the identical disk of some amount of capacity according to the difference of use-pattern, be polymerized to a large virtual memory facilities; When disk size is inconsistent, the disk of minimum capacity of take is the disk group that basis forms; Soft RAID refers to by software the disk of some equal amount of capacity or subregion according to the difference of use-pattern, is polymerized to a large virtual memory facilities; When disk size is inconsistent, the disk of minimum capacity of take is the disk group that basis forms;
In order to meet the demand of different clients' different application scene, minicomputer system is when deployment operation system, for realizing redundancy mainly by disposing two kinds of methods of the many redundancies of hard RAID of external storage and built-in hard disk at present; By disposing external storage, realize redundancy and be, need in system, increase optical fiber switch equipment, by the communication of optical fiber switch equipment, external storage can be utilized as system installing space; By the many redundancy approachs of hard RAID of built-in hard disk, need in system, adopt built-in hard RAID card.
Above-mentioned two kinds of methods, by disposing the redundancy approach of external storage, need the extra hardware device that increases, and realize the enforcement debugging work that relates to plurality of devices in redundancy process, need the technician's of relevant device human resources to drop into, and due to the increase of communication link, increased the risk of system stability aspect; And the hard RAID method of employing built-in hard disk, built-in hard RAID card has increased system redundancy cost greatly.And need to adjust the structure of machine intimate when increasing RAID card, increased the probability that hardware device goes wrong; Meanwhile, built-in hard RAID card has also increased the link range of system disk to mainboard, has reduced the performance of entire system.
Summary of the invention
