In the prior art, in order to run more services on a physical Network, a Virtual Local Area Network (VLAN) manner is generally adopted to deploy multiple Virtual networks on the same physical Network, where the Virtual networks include, for example, management networks, Virtual Machine networks, vmotions, VSANs (Virtual storage Area networks), and the like.
However, the division of the virtual network by the VLAN is limited by the number of VLAN IDs (identity numbers), which is generally 4096 as an upper limit, and thus cannot perform high-granularity differentiation on network traffic. For example, in one physical network, it is highly likely that traffic of all VMs (Virtual machines) is allocated to the same VLAN, i.e., all Virtual machines share the same Virtual network.
In addition, in the prior art, each virtual machine has a corresponding Logical Volume, and different Logical volumes corresponding to different virtual machines or different Logical volumes corresponding to the same virtual machine may use the same IP (internet protocol) address, so that at present, when allocating traffic, traffic is uniformly allocated to only one VLAN, if multiple virtual services, such as multiple virtual machines, are operated in one VLAN, the virtual machines can only obtain traffic in a contention manner, which results in increased contention among the virtual machines, and also causes severe crosstalk among the virtual machines, and a situation that a virtual machine that needs to use traffic cannot compete for traffic may occur, which affects the traffic of each virtual machine, and also causes a decrease in network quality.

Detailed Description
In the process of the infrastructure evolution from the converged infrastructure to the hyper converged infrastructure of the data center, the nodes in the infrastructure are changed from original single functional nodes of different types, such as single computing nodes or storage nodes, into unified multifunctional nodes, i.e., converged nodes. Such a fusion node generally has a homogenous structure and functions exactly the same in the infrastructure.
For example, referring to fig. 1, fig. 1 includes three nodes, which are a control node, a fusion node 1 and a fusion node 2, where the control node is used to complete a corresponding control function, and the control node and the fusion node have different functions. The functions of the fusion node 1 and the fusion node 2 are, for example, identical and are both responsible for providing a computation virtualization function and a storage virtualization function.
Or for example, referring to fig. 2, fig. 2 includes three nodes, which are a control node, a fusion node 1 and a fusion node 2, where the control node is used to complete a corresponding control function, and the control node and the fusion node have different functions. The fusion node 1 and the fusion node 2 have respective emphasis on functions, for example, the fusion node 1 is a computing weight node mainly responsible for providing a computing virtualization function, and the fusion node 2 is a storage weight node mainly responsible for providing a storage virtualization function.
Fig. 1 and fig. 2 are only examples of a small number of nodes, and in practical applications, the number, functions, and deployment of the nodes are not limited to these.
The fusion of the functions requires that a network connected to the nodes is also fused correspondingly, that is, a service network (service network) of the past separation networking, or a front end network (front end network) and a storage network (storage network) or a back end network (back end network) are changed into a unified converged network, so as to achieve the purposes of simplifying a network structure and reducing networking and operation and maintenance costs.
The technical scheme in the embodiment of the invention can be applied to a super-fusion infrastructure, and the specific deployment mode can refer to fig. 1 or fig. 2.
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.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship, unless otherwise specified.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 3, an embodiment of the present invention provides a method for creating a logical volume, where a flow of the method is described as follows.
Step 301: a first IP address is assigned to the logical volume.
The creation of the logical volume may occur at the time of creation of the virtual machine, i.e., the creation of the logical volume for the virtual machine to be created, or may occur after the creation of the virtual machine, i.e., the creation of a new logical volume for the virtual machine that has already been created.
If the virtual machine is created, first, the Hypervisor (virtualization controller) may create a profile (document) of a new virtual machine, and the Hypervisor may send a request for adding a virtual network card to the virtual network controller and send a request for creating a new logical volume from the mirror image, that is, a request for creating a new logical volume, to the virtual storage controller.
Wherein the method may be performed by a virtual storage controller.
If the method is applied to the infrastructure shown in fig. 1, the virtual storage controller may be located in any one of the fusion nodes in the infrastructure shown in fig. 1, the virtual network controller may also be located in any one of the fusion nodes in the infrastructure shown in fig. 1, and the virtual storage controller and the virtual network controller may be located in the same fusion node or may also be located in different fusion nodes. The Hypervisor may be located in the control node shown in fig. 1, or may be located in any of the fusion nodes shown in fig. 1.
If the method is applied to the infrastructure shown in fig. 2, the virtual storage controller may be located in the fusion node 2 in the infrastructure shown in fig. 2, and the virtual network controller may be located in the fusion node 1 in the infrastructure shown in fig. 2. The Hypervisor may be located in the control node shown in fig. 2, or may be located in any of the fusion nodes shown in fig. 2.
Optionally, the Hypervisor, the virtual network controller, and the virtual storage controller may be considered as three functional modules, and the three functional modules may be located in different nodes or may also be located in the same node. If the three functional modules are located in different nodes, the nodes can be considered to belong to the same system, and the architecture of the system is a super-convergence infrastructure.
The steps in the method can be considered to be performed by the three functional modules respectively.
When the virtual storage controller receives a request for creating a new logical volume, a fusion node for creating the new logical volume is selected in a system, which is referred to as a hyper-fusion infrastructure. For example, the virtual storage controller may select a fusion node for creating the new logical volume based on the node weights for storage scheduling. The selected fusion node of the virtual storage controller may be the same as the fusion node where the virtual storage controller is located, or may be a different fusion node. However, in general, the fusion node where the logical volume is located is a storage node capable of providing a storage virtualization function.
Optionally, in this embodiment of the present invention, allocating a first IP address to the logical volume includes:
a first IP address, a first target name, and TCP (Transmission Control Protocol) port information are allocated to the logical volume.
That is, after selecting the fusion node, the virtual storage controller allocates a target name to the new logical volume, in this embodiment, the target name is referred to as a first target name, and the virtual storage controller may query the virtual network controller, and allocate a first IP address and TCP port information to the new logical volume through the virtual network controller.
After the virtual storage controller queries the virtual network controller, if the virtual storage controller is rejected by the virtual network controller, the virtual storage controller ends creating the new logical volume, and if the virtual network controller assigns the first IP address and the TCP port information to the first target name, the virtual storage controller may bind the first IP address, the TCP port information, the first target name, and the port information of the corresponding virtual network card, which may be understood as setting a correspondence relationship between the first IP address, the TCP port information, the first target name, and the port information of the corresponding virtual network card.
In this embodiment of the present invention, the first target name may be, for example, an iSCSI (internet Small Computer System Interface) name, but may also be other names.
The virtual network controller learns that the next action of the virtual storage controller is to create a logical volume according to an inquiry of the virtual storage controller (i.e., inquiring that a first IP address and TCP port information are allocated to a new logical volume), and then, the virtual network controller may set a corresponding priority and a corresponding bandwidth limit for a traffic corresponding to the logical volume to be created by the virtual storage controller (i.e., a storage traffic of the virtual machine) according to a preset policy. When the device is specifically set, the device can be set according to actual requirements. For example, if the storage traffic of a virtual machine is to be guaranteed, the virtual storage controller may set the priority of the traffic of the logical volume to be created to a high priority, and its bandwidth limit to a high bandwidth (e.g., 3 Gbps). Specifically, when setting information such as the priority of traffic of different logical volumes, the virtual network controller may perform setting according to an IP address allocated to the logical volume, TCP port information, and a Media Access Control (MAC) address of a corresponding virtual network card.
In the embodiment of the present invention, although the information such as the priority and the bandwidth limit set by the virtual network controller is used, since the logical volume is located on the virtual storage controller and the virtual storage controller receives the setting of the virtual network controller, the information such as the priority and the bandwidth limit set by the virtual storage controller for the logical volume may be considered to some extent.
Step 302: and creating a logical volume, wherein the logical volume corresponds to the first IP address.
The virtual storage controller performs the operation of creating a logical volume from the image. It can be considered that an image of the new logical volume already exists, and after the new logical volume is created, all data is copied from the image, and thus it is referred to as "creating logical volume from image".
If the priority of the storage traffic of the new logical volume is set as high priority and the bandwidth limitation is set as high bandwidth, the storage traffic from the node where the mirror image is located to the node where the new logical volume is located has high priority and high bandwidth when being transmitted in the network, so that the method can be quickly completed and the virtual machine creation process is accelerated.
The new logical volume not only corresponds to the first IP address, but also corresponds to the first target name, TCP port information, and information of the corresponding virtual network card, such as port information of the virtual network card, MAC address, and the like.
Step 303: and respectively attaching the logical volumes to the virtual disk drives corresponding to the at least one virtual machine.
After the creation of the new logical volumes is completed, the new logical volumes may be respectively attached to the virtual disk drives of the at least one virtual machine. If a new logical volume is attached to the virtual disk drives of multiple virtual machines, it is equivalent to the logical volume being a logical volume shared by the multiple virtual machines.
The process of attaching the new logical volume to the virtual disk drive of the virtual machine may be performed by the Hypervisor or may be performed by the virtual storage controller.
Optionally, in this embodiment of the present invention, if the process of creating the logical volume occurs when the virtual machine is created, the method further includes:
respectively creating a virtual network card for all or part of at least one virtual machine;
and respectively allocating third IP addresses to the created virtual network cards.
For example, to set the created logical volume as a shared logical volume among virtual machine 1, virtual machine 2, and virtual machine 3, where virtual machine 1 is already created and virtual machine 2 and virtual machine 3 are being created, virtual network cards may be created for virtual machine 2 and virtual machine 3, respectively, and IP addresses may be assigned to the two created virtual network cards, respectively. In the embodiment of the present invention, the IP address allocated to the virtual network card is referred to as a third IP address, and the third IP addresses allocated to different virtual network cards are different.
Specifically, the virtual network controller may create a virtual network card for the virtual machine according to the requirement of the Hypervisor, and the virtual network card may be located at a node where a document of the new virtual machine is located.
After the virtual network card is created, the IP address of the virtual network card may be obtained, for example, the IP address of the virtual network card may be obtained through a DHCP (Dynamic Host Configuration Protocol) server.
In the embodiment of the invention, the IP addresses corresponding to the virtual network cards of the virtual machines are different, so that when the service flow is distributed to each virtual machine, the IP addresses of the different virtual network cards can be independently distributed, the competition of the service flow by a plurality of virtual machines is avoided, the normal operation of the service of each virtual machine is ensured as much as possible, and the mutual interference among the virtual machines is reduced.
Creating a virtual network card and creating a logical volume, the execution sequence of the two processes can be arbitrary.
Optionally, in this embodiment of the present invention, after creating the virtual network card for all or part of the at least one virtual machine, the method further includes:
and setting the priority of the service flow corresponding to all or part of the created virtual network cards as low priority.
The virtual network controller may set a corresponding priority and a corresponding bandwidth limit for a traffic corresponding to the virtual network card (i.e., a traffic of the virtual machine) according to a preset policy. When the device is specifically set, the device can be set according to actual requirements. For example, if the storage traffic of the virtual machine is to be guaranteed, the priority of the traffic corresponding to the virtual network card may be set as low priority, and the bandwidth limit may be set as low bandwidth (e.g., 1Gpbs), so that when the network quality is not good, the storage traffic may be guaranteed preferentially. Specifically, when setting information such as the priority of the traffic of different virtual network cards, the virtual network controller may set the traffic according to the IP address, the MAC address, and the like allocated to the virtual network cards, that is, the different virtual network cards are distinguished by the information, so that the traffic information is set for the different virtual network cards respectively.
Optionally, in the embodiment of the present invention, after the third IP addresses are respectively allocated to the created virtual network cards, specifically, after the first virtual machine is created, the method further includes:
receiving first information, wherein the first information is used for indicating service flow allocated to a first virtual machine in at least one virtual machine, and the service flow is the flow corresponding to a virtual network card of the first virtual machine.
Optionally, in the embodiment of the present invention, after the third IP addresses are respectively allocated to the created virtual network cards, specifically, after the first virtual machine is created, the method further includes:
and receiving second information, wherein the second information is used for indicating the storage flow allocated to the first virtual machine in the at least one virtual machine, and the storage flow is the flow corresponding to the logical volume.
In the embodiment of the present invention, the allocation of the service traffic and the storage traffic to the virtual machine may be performed by Hypervisor, or may be performed by other functional modules.
In the embodiment of the invention, the logical volume and the virtual network card of the virtual machine are respectively corresponding to information such as IP addresses, so that the service flow and the storage flow of the virtual machine can be independently distributed when the flow is distributed, and the corresponding flow can be ensured according to requirements. And the IP addresses of the logical volumes are different, and the IP addresses of the virtual network cards are different, so that when the flow is distributed, the corresponding flow can be distributed for the different logical volumes and the virtual network cards respectively, and the actual network requirements are met better.
In the embodiment of the present invention, the newly created logical volume may be set as a shared logical volume of a plurality of virtual machines, and in the running process of a virtual machine, there may be a case where one logical volume already in a running state needs to be set as a shared logical volume of a plurality of virtual machines, so that the logical volume may be directly attached to a virtual disk drive of a corresponding virtual machine.
For example, virtual machine 1, virtual machine 2, and virtual machine 3 are all in a running state, virtual machine 1 having logical volume 1 and logical volume 2, virtual machine 2 having logical volume 3, and virtual machine 3 having logical volume 4. In the operation process, the logical volume 2 needs to be set as a shared logical volume of the virtual machine 1, the virtual machine 2, and the virtual machine 3, and then the logical volume 2 originally attached to only the virtual disk drive of the virtual machine 1 needs to be respectively attached to the virtual disk drives of the virtual machine 2 and the virtual machine 3.
In the embodiment of the present invention, during the operation of the virtual machine, the traffic policy of the storage traffic set for the logical volume may be adjusted according to the actual situation of the virtual machine, for example, the traffic policy may include the priority and the bandwidth limitation of the storage traffic set for the logical volume. For example, the priority of the storage traffic of the logical volume may be set to a high priority at the time of creation of the logical volume, and then it may be subsequently adjusted to a low priority. And, for example, the bandwidth limit of the logical volume may be set to a high bandwidth at the time of creation of the logical volume, which may then be subsequently adjusted to a low bandwidth.
In the embodiment of the present invention, when the virtual machine runs, the traffic policy of the service traffic set for the virtual network card may be adjusted according to the actual situation of the virtual machine, for example, the traffic policy may include the priority and the bandwidth limitation of the service traffic set for the virtual network card. For example, when the virtual network card is created, the priority of the storage traffic of the virtual network card may be set to be low priority, and then the storage traffic of the virtual network card may be adjusted to be high priority subsequently. And, for example, the bandwidth limit of the virtual network card may be set to a high bandwidth at the time of creation of the virtual network card, and then it may be subsequently adjusted to a low bandwidth.
The flow strategy of the logical volume and the flow strategy of the virtual network card are adjusted in two independent processes, one of the processes can be optionally adjusted according to actual conditions, or both the processes can be adjusted, and the adjustment time can be any. How to adjust the method is not limited in the embodiments of the present invention.
Optionally, in this embodiment of the present invention, after attaching the logical volume to the virtual disk drive corresponding to the at least one virtual machine, the method further includes:
allocating a second IP address for the backup logical volume of the logical volume;
and creating a backup logical volume, wherein the backup logical volume corresponds to the second IP address.
That is, in the embodiment of the present invention, after the logical volume is created, a backup logical volume may be created for the logical volume. The process of creating a backup logical volume for a logical volume may occur just after the logical volume is created or may occur after the logical volume has already started working, and the present invention is not limited thereto.
The backup logical volume is created, that is, a completely new logical volume is created, and the node where the backup logical volume is located and the node where the original logical volume is located may be the same node or may be different nodes. Because a completely new logical volume is created, a new IP address is also allocated to the backup logical volume, and in the embodiment of the present invention, the IP address allocated to the backup logical volume is referred to as a second IP address. In addition, in addition to allocating an IP address to the backup logical volume, a unique target name (e.g., iSCSI name), TCP port information, and the like may be allocated to the backup logical volume.
After the backup logical volume is created, the backup logical volume may not be attached to the virtual disk drive of the virtual machine corresponding to the primary logical volume.
Then, if the original logical volume fails, there may be two methods for using the backup logical volume:
1. the original logical volume is only the data stored with problems, but has no hardware failure and can be continuously used. The data in the backup logical volume can be copied and the original logical volume can be continuously used;
2. the original logical volume has hardware failure and can not be used continuously. The original logical volume may be detached (detach) from the virtual disk drive of the corresponding virtual machine and the metadata corresponding to the original logical volume may be deleted, thus deleting the original logical volume. And then attaching the backup logical volume to the virtual disk drive of the virtual machine corresponding to the original logical volume, so that the original logical volume is replaced by the backup logical volume. Of course, after replacement, the backup logical volume becomes the used logical volume, and the backup logical volume may be created again for the used logical volume.
Optionally, in this embodiment of the present invention, after attaching the logical volume to the virtual disk drive corresponding to the at least one virtual machine, the method further includes:
acquiring state information of the logical volume, and storing the state information in the logical volume; the state information is used to restore the state of the logical volume.
That is, in the embodiment of the present invention, a "snapshot" function may be implemented. For example, status information of the logical volume may be periodically acquired, and the status information may include information such as operation data of the logical volume, and the acquired status information may be stored in the logical volume. Thus, when the logical volume needs to restore the previous state, the logical volume can be restored according to the stored state information.
For example, a logical volume is created on 5/1 th 2009, and state information of the logical volume is obtained on 5/24 th 2009. If the logical volume needs to be restored to the previous state on 24 th 6 th 2009, the logical volume can be restored based on the state information obtained on 24 th 5 th 2009, so that the logical volume can be restored to the operating state on 24 th 5 th 2009.
