First, a method for allocating storage resources provided in the embodiment of the present application is described below.
Fig. 1 is a flowchart illustrating a method for allocating storage resources according to an embodiment of the present application, where the method may be applied to a storage server, such as a cloud host. As shown in fig. 1, the method may include the steps of:
s110, receiving a storage space allocation application request sent by user equipment.
The storage space allocation application request comprises the service type of the service to be stored, and the storage space allocation application request sent by the user equipment can be received through communication connection with the user equipment.
S120, determining storage resource use information of a storage pool corresponding to the service type of the service to be stored according to the service type of the service to be stored.
The storage pool corresponding to the database type service can be a Solid State Disk (SSD) pool, for example, the performance of a magnetic disk required by the database type service is higher; the performance of a disk required by the web application type service of the world wide web is general, and the storage pool corresponding to the web application type service can be a Serial Attached SCSI (SAS) pool; and if the performance of the magnetic disk required by the program backup service is lower, the storage pool corresponding to the program backup service can be a serial port hard disk SATA pool.
S130, when the storage resource use information meets the preset storage resource index information of the storage pool, the storage resources are allocated to the service to be stored.
When the storage resource use information meets the preset storage resource index information of the storage pool, the storage space of the storage pool can meet the storage requirement of the service to be stored, and therefore the storage resource is allocated to the service to be stored. And when the storage resource use information does not meet the preset storage resource index information of the storage pool, indicating that the storage space of the storage pool cannot meet the storage requirement of the service to be stored, and sending notification information which cannot be stored to the user equipment.
According to the method and the device, the storage resources are allocated to the services to be stored based on the storage space allocation application request sent by the user equipment, the storage resource use information of the storage pool corresponding to the service type of the services to be stored is determined according to the service type of the services to be stored in the storage space allocation application request, and different storage requirements of different services to be stored are fully considered; when the storage resource usage information meets the preset storage resource index information of the storage pool, the storage resources are allocated to the service to be stored, whether the storage resource usage information of the storage pool is matched with the preset storage resource index information or not is fully considered, and the storage resource allocation is performed only under the condition of matching, so that the allocated storage space is matched with the service to be stored, the condition that the storage space resource is idle due to the fact that a small service to be stored is stored in a large storage space resource is avoided, the condition that the large service to be stored is stored in a small storage space is also avoided, the storage failure due to the fact that the large service to be stored is stored in the small storage space is avoided, and the application rate of the storage space resource is high.
In one embodiment, the presetting of the storage resource indicator information may include: storing a first upper limit value of the occupied ratio of a front port corresponding to the logic unit and a second upper limit value of the occupied ratio of the logic unit; a storage pool may include multiple storage logical units; the storage resource usage information may include: the occupied ratio of the front port corresponding to the storage logic unit and the occupied space ratio of the storage logic unit S130 may include:
and when the occupied ratio of the front port corresponding to the storage logic unit is smaller than a first upper limit value and the occupied space ratio of the storage logic unit is smaller than a second upper limit value, allocating storage resources for the service to be stored.
The first upper limit value is a preset index used for controlling the upper limit of the front port occupation corresponding to the storage logic unit, and may be set to 50% for example; the second upper limit value is a preset index for controlling the upper limit of the occupied space ratio of the storage logic unit, and may be set to 90%, for example. And when the occupied ratio of the front port corresponding to the storage logic unit is smaller than the first upper limit value and the occupied ratio of the storage logic unit is smaller than the second upper limit value, indicating that the storage pool still has resources and performing service storage.
In one embodiment, the method may further comprise:
and S140, comparing the storage resource use information with preset storage resource index information to obtain a comparison result representing the storage use degree of the storage pool.
S150, when the comparison result meets the preset storage pool adjusting condition, adjusting the storage pool.
Because the required storage resources may be different even for the same type of service to be stored, and the storage resources in the same type of storage pool may also be different, in order to make the correspondence between the service to be stored and the service pool more accurate, the storage pool is adjusted by comparing the storage resource usage information with the preset storage resource index information.
According to the embodiment of the application, the storage pool is adjusted by comparing the storage resource use information with the preset storage resource index information, so that the corresponding relation between the service to be stored and the storage pool is more accurate, and a more appropriate storage pool can be allocated for the service to be stored.
In an embodiment, the preset storage resource indicator information may include a first upper limit and a first lower limit of a front port occupied ratio corresponding to the storage logic unit, and the storage resource usage information may include the front port occupied ratio corresponding to the storage logic unit, S150 may include:
when the occupied ratio of the front port corresponding to the storage logic unit is less than a first lower limit value continuously in a preset time period, recovering the unoccupied front port; and adding the front port when the occupied ratio of the front port corresponding to the storage logic unit is larger than the first upper limit value continuously within a preset time period.
The first lower limit is a preset index used for controlling the lower limit of the front port occupation corresponding to the storage logic unit, and may be set to 20% for example; when the occupied ratio of the front port corresponding to the storage logic unit is smaller than the first lower limit value continuously within a preset time period, the fact that the front port corresponding to the storage logic unit is too much idle is indicated, storage resource waste exists, and therefore the unoccupied front port is recycled; when the occupation ratio of the front port corresponding to the storage logic unit is larger than the first upper limit value continuously within the preset time period, it indicates that the front port corresponding to the storage logic unit is busy in service, and the storage resource is deficient, so that the capacity expansion of the storage resource is performed, for example, the front port is added.
According to the embodiment of the application, the storage pool is adjusted by comparing the occupied ratio of the front port with the first upper limit value and the first lower limit value of the occupied ratio of the front port, so that the front port of the storage pool is more matched with the service to be stored, and the storage pool can store the service to be stored.
In one embodiment, the presetting of the storage resource index information may include: storing a second upper limit value and a second lower limit value of occupied space ratio of the logic unit; the storage resource usage information may include: storing occupied space ratio of the logic unit; the storage pool may include a plurality of storage logical units, and S150 may include:
when the occupied space ratio of the storage logic unit is smaller than a second lower limit value continuously in a preset time period, recovering the unoccupied storage space of the storage pool; and when the occupied space ratio of the storage logic unit is larger than the second upper limit value continuously in the preset time period, expanding the storage space of the storage pool.
Wherein, the second lower limit value is a preset index for controlling the lower limit of the occupied space ratio of the storage logic unit, and may be set to 20% for example; when the occupied space ratio of the storage logic unit is less than a second lower limit value continuously in a preset time period, indicating that the storage space of the storage pool is idle, and recovering the unoccupied storage space of the storage pool; when the occupied space ratio of the storage logic unit is larger than the second upper limit value continuously within the preset time period, the storage space of the storage pool is indicated to be deficient, and therefore the storage space of the storage pool is expanded.
According to the embodiment of the application, the storage pool is adjusted by comparing the occupied space ratio of the storage logic unit with the second upper limit value and the second lower limit value of the occupied space ratio of the storage logic unit, so that the storage space of the storage pool is more matched with the service to be stored, and the storage pool can store the service to be stored.
In one embodiment, the presetting of the storage resource indicator information may include: storing a third upper limit value and a third lower limit value of a busy index of the logic unit; the storage resource usage information may include: storing a busy indicator of the logic unit; the storage pool may include a plurality of storage logical units, and S150 may include:
and acquiring the performance information of the storage resource pool corresponding to each service type.

The third upper limit value and the third lower limit value are preset indexes used for controlling the upper limit and the lower limit of a busy index of the storage logic unit. When the busy index of the storage logic unit is continuously smaller than a third lower limit value within a preset time period, the fact that a large storage resource is idle when the storage pool corresponding to the service type of the current service to be stored is used for storing the current service to be stored is indicated, and therefore the storage pool corresponding to the service type of the service to be stored is replaced by other storage pools with lower performance according to the performance information; when the busy index of the storage logic unit is continuously greater than the third upper limit value within the preset time period, it indicates that the storage pool corresponding to the service type of the current service to be stored cannot meet the storage requirement of the current service to be stored, and therefore, according to the performance information, the storage pool corresponding to the service type of the service to be stored is replaced by another storage pool with higher performance.
According to the embodiment of the application, the storage pool corresponding to the service type of the service to be stored is updated by comparing the busy index of the storage logic unit with the third upper limit value and the third lower limit value of the busy index of the storage logic unit, so that the storage space of the updated storage pool is more matched with the service to be stored, and the storage pool can store the service to be stored.
According to the method and the device, the storage resources are allocated to the services to be stored based on the storage space allocation application request sent by the user equipment, the storage resource use information of the storage pool corresponding to the service type of the services to be stored is determined according to the service type of the services to be stored in the storage space allocation application request, and different storage requirements of different services to be stored are fully considered; when the storage resource usage information meets the preset storage resource index information of the storage pool, the storage resources are allocated to the service to be stored, whether the storage resource usage information of the storage pool is matched with the preset storage resource index information or not is fully considered, and the storage resource allocation is performed only under the condition of matching, so that the allocated storage space is matched with the service to be stored, the condition that the storage space resource is idle due to the fact that a small service to be stored is stored in a large storage space resource is avoided, the condition that the large service to be stored is stored in a small storage space is also avoided, the storage failure due to the fact that the large service to be stored is stored in the small storage space is avoided, and the application rate of the storage space resource is high.
