- an embodiment of the present invention provides a resource allocation method. As shown in FIG. 1, the method specifically includes the following steps:
- the number of required resources is first determined. If it is determined that the number of required resources is not greater than the number of available rack groups established based on TOR, then the available rack group with the same number of required resources is selected from the available rack group. Resources are allocated.
- the available rack group here refers to the rack group with available resources in the rack group.
- a resource request message When the resource demander needs resources, a resource request message will be issued.
- the resource request message will carry the required resources and the number of required resources, such as DCN, Appdomain, SystemId, Image, physical zone, machine model, number of instances, etc. , And then determine the required resources and the number of required resources from the resource request information.
- the physical area refers to the divided physical area, such as the management area, the external area, the server group area, etc.; the machine model can be created according to the needs of the business, and the corresponding resources can be created according to the needs of the business. Corresponding requirements.
- resources may be physical host resources, virtual host resources, or a combination of physical host resources and virtual host resources.
- the resource demander A issues a resource request message
- the resource determined in the resource request message is 5 physical host resources and 3 virtual host resources.
- the number of required resources After determining the number of required resources, compare the number of required resources with the number of available rack groups established based on TOR. If the number of required resources is not greater than the number of available rack groups, select and Available resources with the same number of required resources are allocated, and the available rack group here is a rack group with available resources in the rack group.
- the number of required resources here is the same as the number of subsequent instances, and both represent the number of resources required by the resource demander.
- the conventional rack is 42U and has 21 seats.
- the conventional physical host is 2U, so a rack can hold up to 21 physical hosts and one rack group. There can be up to 42 physical hosts.
- the physical host can no longer be allocated. If there are 42 physical hosts in a rack group and at least one physical host is not occupied, it means that the rack group is an available rack group.
- the available resources are allocated.
- the following describes the required resources as physical host resources and the required resources as virtual host resources.
- Case 1 The required resources are physical host resources.
- the resource usage rate of the available rack group that is, the ratio of the number of unoccupied physical hosts under the rack group to the total number of physical hosts, and the result is the resource usage rate of the available rack group.
- the resource utilization rate of rack group 1 is 50%.
- the resource usage rate of available rack group is 10%
- the resource usage rate of available rack group 2 is 15%
- the resource usage rate of available rack group 3 is 30%
- the resource usage rate of available rack group 4 The resource utilization rate of the available rack group 5 is 35%
- the resource utilization rate of the available rack group 5 is 50
- the number of resources required is 2, then select 2 available rack groups with low resource utilization from the 5 available rack groups, namely Available rack group 1 and available rack group 2.
- the selection method can be random selection or selection through preset rules. This application is not limited.
- available rack group 1 and available rack group 2 For example, two available rack groups with low resource usage are selected, available rack group 1 and available rack group 2, and available rack group 1 has 2 unoccupied physical hosts, physical host 1 and physical host 2. There are 3 unoccupied physical hosts in the available rack group 2, physical host 3, physical host 4 and physical host 5.
- the selected physical host SN and IP address are returned to the terminal where the user is located.
- Case 2 The required resources are virtual host resources.
- Select an available rack group with the same amount of resources as the required resource from the available rack group select an IP address with the same number of resources as the required resource from the available rack group with a small resource usage, and use the resource Select the resource name from the available rack group with low rate, determine the parent machine SN and virtual host IP address corresponding to the virtual host according to the IP address and resource name; send the parent machine SN and virtual host IP address to the user's terminal.
- IP address pool is allocated the same number of IP addresses as the required resources, and the physical host name is incrementally allocated according to the CMDB, and the allocated IP address and physical host name are returned to the user.
- the host name creation rule can be: CN+city+IDC+number.
- the first host name created by the rule engine is CNSZFT05010001
- the second host name is CNSZFT05010002
- FT represents a 0501 computer room
- 0001 represents the serial number.
- the above is an explanation of resource allocation when the number of required resources is not greater than the number of available rack groups. If the number of required resources is greater than the number of available rack groups, it means that the rack group cannot meet the required resources. If the required resources are If it is a physical host resource, the available resources of at least one available rack group in the available rack group can be repeatedly allocated.
- the following is an example to illustrate that the required resources are physical host resources.
- the number of physical host resources required is 4, the available rack group is available rack group 1, available rack group 2, and available rack group 3.
- the number of physical resources required 4 is greater than the number of available rack groups 3.
- the available rack group 3 was repeatedly allocated.
- the required resource is a virtual host resource, and the number of required resources is greater than the number of available rack groups, and is not greater than the number of available physical hosts of the business system corresponding to the required resource, then from the available physical hosts of the business system The host selects the available resources that are the same as the required number of resources for allocation.
- the available resources with the same amount of resources as the required resources are selected from the available physical hosts of the business system for allocation, and the AZ of Openstack can be obtained based on the rack group, that is, the set of unoccupied physical hosts. Then, from the IP address pool of the virtual network segment, an IP address equal to the required number of resources is allocated, the physical host name is incrementally allocated according to the CMDB, and the allocated IP address and physical host name are sent to the terminal where the user is located.
- the AZ of Openstack is obtained based on the rack group, which can be defined rules created in advance when building Openstack, that is, there is a corresponding relationship between the rack group and the AZ. After the rack group is determined, the AZ can be determined according to the corresponding relationship ;
- the IP address pool of the virtual network can be a virtual network segment created in advance when Openstack is built, and the virtual network segment constitutes the IP address pool of the virtual network.
- the required resources are virtual host resources, and the number of required resources is greater than the number of available rack groups, and is greater than the number of available resources in the business system corresponding to the required resources, it means that the existing resources cannot meet the required resources. Therefore, an abnormal prompt is displayed and no resource allocation is performed.
