Description
Technical Field
The invention relates to the field of small-sized computers, in particular to a method for realizing multiple redundancies of a flexible disk array (RAID) and a small-sized computer system thereof.
Background
A disk Array (RAID) is a technology that combines a plurality of Independent Disks (physical hard Disks) in an Array manner to form a disk group, so as to provide higher storage performance and data redundancy than a single disk. A large amount of data can be conveniently stored on the hard disk by using RAID. RAID combines a plurality of small-capacity physical disks into one large-capacity virtual storage device, and can improve physical storage efficiency (i.e., data read/write) or enhance the security of data storage by redundancy (a redundancy method in which the same data is stored in different places of a plurality of hard disks).
RAID is divided into hardware RAID and software RAID in practical applications. The hardware RAID aggregates a plurality of disks with the same capacity into a large virtual storage device through a RAID card according to different use modes; when the capacities of the magnetic disks are inconsistent, the magnetic disk group is formed on the basis of the magnetic disk with the minimum capacity; the soft RAID is a large virtual storage device which is formed by aggregating a plurality of disks or partitions with the same capacity and size into a large virtual storage device through software according to different use modes; when the capacities of the magnetic disks are inconsistent, the magnetic disk group is formed on the basis of the magnetic disk with the minimum capacity;
in order to meet the requirements of different application scenes of different customers, the existing small computer system mainly adopts two hard RAID multi-redundancy methods of external storage and internal hard disk for realizing redundancy when an operating system is deployed; the redundancy is realized by deploying the external storage, that is, optical fiber switch equipment needs to be added in the system, and the external storage can be used as a system installation space through the communication of the optical fiber switch equipment; the hard RAID multi-redundancy method using a built-in hard disk requires a built-in hard RAID card to be used in the system.
In the two methods, hardware equipment needs to be additionally added by deploying the redundancy method of external storage, the implementation debugging work of various equipment is involved in the redundancy process, the human resource investment of technicians of the corresponding equipment is needed, and the risk in the aspect of system stability is increased due to the increase of communication links; and a hard RAID method with a built-in hard disk is adopted, and a system redundancy cost is greatly increased by a built-in hard RAID card. When the RAID card is added, the internal structure of the machine needs to be adjusted, so that the probability of problems of hardware equipment is increased; meanwhile, the built-in hard RAID card also increases the link distance from the system hard disk to the mainboard, and reduces the overall performance of the system.
