Embodiment 1

[0047] Such as figure 1 As shown, the present invention provides a kind of method that realizes Windows drive letter supports large-scale disk, comprises the steps:

[0048] S1. Obtain disk interface information and serial number; Obtain disk interface information and serial number by disk controller; Described disk interface adopts SAS interface or SATA interface; SAS interface and SATA interface are disk interfaces commonly used at present; Control the hard disk, allocate resources, and adjust data input and output;

[0049] S2. Calculate the number m of disk interfaces;

[0050] S3. Divide the disk interface into several groups according to the number of available drive letters, and encapsulate the disk interface of each group and set it as a virtual disk;

[0051] S4. Assign an available drive letter to each virtual disk, and mount all virtual disks; the number of available drive letters is 24, A and B are used by the system, and the available drive letters are C-Z; the ...

Embodiment 2

[0060] Such as figure 2 As shown, the present invention provides a kind of system that realizes that Windows disk letter supports large-scale disk, comprises disk interface acquisition module 1, is used to obtain disk interface information and serial number; Obtain disk interface information and serial number by disk controller; Disk interface adopts SAS Interface or SATA interface; SAS interface and SATA interface are currently commonly used disk interfaces; the disk controller is used to control the hard disk on the motherboard, allocate resources, and adjust data input and output;

[0061] The disk interface quantity calculation module 2 is used to calculate the disk interface quantity;

[0062] The disk interface grouping module 3 is used to divide the disk interface into several groups according to the number of available drive letters, and encapsulate and set the disk interfaces of each group as a virtual disk; the disk interface grouping module 3 includes: available dr...

Abstract

The invention provides a method and a system for realizing large-scale disk supported by Windows drive letter. The method comprises the following steps: 1, acquiring disk interface information and serial number; 2, calculating that number m of disk interface; 3, dividing that disk interface into several groups accord to the number of usable drive letters, encapsulating the disk interface of each group and setting the disk interface as a virtual disk; 4. Assigning a usable letter to each virtual disk. The system includes a disk interface acquisition module, a disk interface quantity calculationmodule, a disk interface grouping module and a drive letter allocation module. The invention realizes the mapping relationship between a single disk character and multiple disks through encapsulationand virtualization technology, achieves the purpose of simultaneously reading and writing data of all disks, and solves the problem of insufficient disk characters when the number of disks exceeds 24under Windows.

Description

technical field [0001] The invention belongs to the field of virtual disks, and in particular relates to a method and system for realizing Windows disk letters supporting large-scale disks. Background technique [0002] As the functions of server products are updated day by day, the number of disks included in the server is also constantly increasing. The support from a few disks to more than one hundred disks highlights the strength of server products. But at the same time, limited by the limitations of the Windows system, the disk can be recognized by the Windows system, but the system drive letter can only use a limited 24 (C-Z, A, B drive letter system is bound to a special device by default), so when more than 24 When the function of each disk is developed, the disk without a drive letter cannot be fully used. This is a disadvantage of the Windows system. [0003] This is the deficiency of the prior art. Therefore, aiming at the above-mentioned defects in the prior art...
