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; Disk controller is used for on the motherboard 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...

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 obtaining 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 driv...

Abstract

The present invention provides a kind of method and system that realizes that Windows disk letter supports large-scale disk, and method comprises the following steps: S1. Obtain disk interface information and sequence number; S2. Calculate disk interface quantity m; S3. The interface is divided into several groups, and the disk interface of each group is encapsulated and set as a virtual disk; S4. Assigning an available drive letter to each virtual disk. The system includes a disk interface acquisition module, a disk interface quantity calculation module, a disk interface grouping module and a disk letter assignment module. The invention realizes the mapping relationship between a single disk letter and multiple disks through encapsulation and virtualization technology, achieves the purpose of reading and writing data on all disks at the same time, and solves the problem of insufficient disk letters when there are more than 24 disks under 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...
