In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a networking method for SDS storage domains in a virtualization system according to an embodiment of the present invention.
The networking method of the SDS storage domain in the virtualization system comprises the following steps:
step S1: and virtualizing the physical network cards corresponding to the SDS nodes for building the SDS storage domain into a storage switch.
Specifically, each server in the system is used as a carrier of each SDS node for building an SDS storage domain one by one, and each server provides a physical network card for networking the SDS storage domain, which is generally a ten-gigabit network card, for the corresponding SDS node.
In order to fully utilize the resources of the physical network cards corresponding to the SDS nodes, the physical network cards corresponding to the SDS nodes are virtualized into the storage switch, and the storage switch can uniformly manage the resources of the physical network cards to provide a basis for subsequently creating and distributing the virtual network cards to the SDS nodes according to needs, so that the resources of the physical network cards are fully utilized, and the resource waste is avoided.
Step S2: and according to the networking requirements of each SDS node, creating a virtual network card which meets the networking requirements of each SDS node on the storage switch.
Specifically, each SDS node for building the SDS storage domain has its own networking requirement, and generally, the networking requirements of each SDS node are the same, for example, each SDS node needs a virtual network card serving as a data network of the SDS node and a virtual network card for connecting the SDS storage domain for use thereof.
After the networking requirements of each SDS node for building the SDS storage domain are obtained, the virtual network card meeting the networking requirements of each SDS node is built on the storage switch according to the networking requirements of each SDS node, if each SDS node needs one virtual network card as a data network of the SDS node and one virtual network card used for connecting the SDS storage domain for the use of the SDS storage domain, namely each SDS node needs 2 virtual network cards, and the total number of the SDS nodes for building the SDS storage domain is 3, 6 virtual network cards need to be built on the storage switch, so that the networking requirements of each SDS node are met.
Step S3: and distributing a virtual network card for the target SDS node according to the networking requirement of the target SDS node, setting the networking mode of each SDS node, and building an SDS storage domain based on the SDS nodes with the set networking mode.
The target SDS node in step S3 is any one of the SDS nodes used for building the SDS storage domain.
Specifically, after a virtual network card is created on the storage switch that meets the networking requirements of each SDS node, the application allocates the virtual network card to the target SDS node according to the networking requirement of the target SDS node, if the target SDS node requires a virtual network card as the data network of the target SDS node and a virtual network card for connecting the SDS memory domain for its use, two free virtual network cards among the created virtual network cards on the storage switch are allocated to the target SDS node, one virtual network card is used as a data network of a target SDS node (specifically, the virtual network card is added into the target SDS node to be used as a network attribute of the target SDS node), and the other virtual network card is used for connecting an SDS storage domain for the use of the SDS storage domain (specifically, the virtual network card is realized through related deployment operation of the SDS storage domain), so that the networking mode of each SDS node is set.
After the networking mode of each SDS node is set, the SDS storage domain can be built based on the SDS nodes with the networking mode. Therefore, the virtual network card can be created and distributed to the SDS nodes according to needs by using the storage switch, the networking mode is flexible, and the storage performance of the SDS storage domain is improved.
The invention provides a networking method of an SDS (system for data storage) storage domain in a virtualization system, which comprises the steps of virtualizing physical network cards corresponding to SDS nodes for building the SDS storage domain into a storage switch; according to the networking requirements of each SDS node, a virtual network card meeting the networking requirements of each SDS node is established on a storage switch; and distributing a virtual network card for the target SDS node according to the networking requirement of the target SDS node, setting the networking mode of each SDS node, and building an SDS storage domain based on the SDS nodes with the set networking mode. Therefore, the physical network cards corresponding to the SDS nodes are virtualized into the storage switch, and the storage switch can uniformly provide resources of the virtual network cards to the outside, so that the resources of the physical network cards are fully utilized, and resource waste is avoided; in addition, the virtual network card can be created and distributed to the SDS nodes according to needs by using the storage switch, and the networking mode is flexible, so that the storage performance of the SDS storage domain is improved.
On the basis of the above-described embodiment:
as an alternative embodiment, the process of creating a virtual network card on the storage switch according to the networking requirement of each SDS node, includes:
on a storage switch, creating a first virtual network card of a data network as a target SDS node and a second virtual network card for connecting an SDS storage domain for the target SDS node;
correspondingly, the process of allocating the virtual network card to the target SDS node according to the networking requirement of the target SDS node includes:
and allocating the first virtual network card and the second virtual network card to the target SDS node, providing the first virtual network card to the target SDS node as a data network, and connecting the second virtual network card to the SDS storage domain for use.
Specifically, the networking requirements of each SDS node for building the SDS storage domain are the same, and the networking requirements are as follows: m virtual network cards of the data network as SDS nodes and N virtual network cards for connecting the SDS memory domain for use thereof are required (M, N are both positive integers).
Then according to the networking requirement of the target SDS node, M first virtual network cards of a data network as the target SDS node and N second virtual network cards for connecting the SDS storage domain for use are created on the storage switch for the target SDS node, and the M first virtual network cards and the N second virtual network cards are distributed to the target SDS node, so that the M first virtual network cards are provided for the target SDS node as the data network, and the N second virtual network cards are connected with the SDS storage domain for use.
As an optional embodiment, there are a plurality of first virtual network cards;
and the networking method further comprises the following steps:
binding a plurality of first virtual network cards to a logic network card in advance, and dividing the plurality of first virtual network cards into a main virtual network card and a standby virtual network card;
when the target SDS node is used, the main virtual network card is preferentially used as a data network, and until the main virtual network card fails, the standby virtual network card is used as the data network.
Furthermore, in the prior art, a data network of the SDS node is obtained by directly connecting a physical network card to the SDS node in a network card direct connection manner, and if a data network redundancy design is to be implemented, a physical network card needs to be provided for each SDS node in the network card direct connection manner to implement data network redundancy, which is relatively high in cost.
In the method of the virtual storage switch, if the data network redundancy design is to be realized, a plurality of first virtual network cards of the data network as the target SDS nodes are created for the target SDS nodes only by creating the virtual network cards on the storage switch, and additional physical network cards are not needed, so that the configuration is flexible, the cost is saved, and the network stability of the SDS storage domain is improved.
When a plurality of first virtual network cards corresponding to the target SDS node are provided, in order to implement data network redundancy design, the application needs to bind a plurality of first virtual network cards to one logical network card in advance, and a data network redundancy policy is set in advance: and determining which first virtual network cards are used as the main virtual network card and which first virtual network cards are used as the standby virtual network cards in advance, namely dividing the plurality of first virtual network cards into the main virtual network card and the standby virtual network cards in advance. When the target SDS node is used, the main virtual network card is preferentially used as the data network of the target SDS node, and when the main virtual network card fails, the standby virtual network card is used as the data network of the target SDS node.
As an optional embodiment, there are a plurality of first virtual network cards;
and the networking method further comprises the following steps:
binding a plurality of first virtual network cards to a logic network card in advance;
when the target SDS node is used, the plurality of first virtual network cards are all used as data networks, and when any one first virtual network card fails, the task on the failed first virtual network card is transferred to the first virtual network card in the normal state.
Further, when there are a plurality of first virtual network cards corresponding to the target SDS node, in addition to the data network redundancy policy provided in the above embodiment, another data network redundancy policy may be adopted: the plurality of first virtual network cards are all used as main virtual network cards, namely when the target SDS node is used, the plurality of first virtual network cards are all used as data networks, and when any one first virtual network card fails, tasks on the failed first virtual network card are transferred to the first virtual network card in a normal state.
As an optional embodiment, when any one of the first virtual network cards fails, a process of transferring a task on the failed first virtual network card to the first virtual network card currently in a normal state includes:
when any one first virtual network card fails, the tasks on the failed first virtual network card are transferred to the first virtual network card in the normal state in a balanced manner, so that the network bandwidths of the first virtual network cards in the normal state are balanced.
Specifically, when the number of the first virtual network cards corresponding to the target SDS node is two, when the target SDS node is used, both the two first virtual network cards are used as data networks, and when one of the first virtual network cards fails, a task on the failed first virtual network card is transferred to the other first virtual network card in a normal state.
When the number of the first virtual network cards corresponding to the target SDS node is larger than two, the plurality of first virtual network cards are all used as data networks when the target SDS node is used, and when any one first virtual network card fails, tasks on the failed first virtual network card are transferred to the first virtual network card in the normal state in a balanced mode, so that the network bandwidths of the first virtual network cards in the normal state are balanced, and the network performance is improved.
As an alternative embodiment, the storage switch is specifically a storage switch configured with SR-IOV function.
Specifically, the storage switch of the present application is specifically configured as a storage switch with a Single-root I/O virtualization (Single-root I/O virtualization) function, and an SR-IOV network may improve a processor utilization rate, reduce a network delay, and increase a throughput of the network, thereby providing better network performance.

For example, the physical network cards 1 and 2 belong to one server, the physical network cards 3 and 4 belong to one server, and the physical network cards 5 and 6 belong to one server. The physical network cards 1, 3 and 5 are directly communicated to three SDS nodes one by one in a network card direct communication mode to serve as a data network of the SDS nodes; the physical network cards 2, 4, 6 set up a data network switch for connecting the SDS memory domain for use thereby.

Therefore, the networking mode of the SDS storage domain is optimized in the virtualization system, the physical network cards corresponding to the SDS nodes in the SDS storage domain are unified to serve as the virtual storage switch, the virtual network cards are provided for the SDS nodes to serve as the data network, the mode that the physical network cards are directly used as the data network and the data network switch in a mixed mode is omitted, the deployment process is simplified, and meanwhile the network stability and the storage performance of the SDS storage domain are improved.
