Description
Technical field
The present invention relates to cloud platform network attached storage technical field, more particularly to a kind of attached storage of distributed network
(Network Attached Storage, referred to as NAS) method and system.
Background technology
Increasing cloud platform provider provides NAS services, the NAS service modes of cloud platform in its cloud platform at present
It is predominantly following two：
(1) list NAS virtual machines (Virtual Machine, referred to as VM) pattern
Fig. 1 is the Organization Chart of single NAS VM patterns of prior art, as shown in figure 1, under this architecture, user provides itself
One user of virtual router 12 of project creates NAS virtual machines 13；System is that NAS virtual machines 13 create a Microsoft Loopback Adapter,
It is bound with the port of the virtual router 12 of user, is made user virtual machine 11 and the intercommunication of NAS virtual machines 13；System is
NAS virtual machines 13 create another Microsoft Loopback Adapter, and it is bound with the port of routing device 14 of storage inside network, make NAS
Virtual machine 13 is connected with rear end storage cluster；NAS virtual machines by the carry of rear end storage file system 15 to local, as network text
Part system (Network File System, referred to as NFS) server or universal network file system (Common
Internet File System, referred to as CIFS) server, externally provide service by NFS or CIFS.
There is following drawback in the cloud platform NAS patterns shown in Fig. 1：NAS virtual machines connection rear end is created inside cloud platform
Storage, and externally provide NAS services using rear end storage as nfs server or CIFS servers.Under this pattern, only at certain
One NAS virtual machine, when user carries out a large amount of big file read-writes, the network in other calculate nodes are provided in one calculate node
Resource is now in idle condition, underuses effective Internet resources, and the network performance of NAS virtual machines just becomes bottle
Neck.It is this to be provided under the pattern that NAS is serviced using inside NAS virtual machines, it is impossible to make full use of effective Internet resources, cause interior
Portion's virtual machine own net performance turns into bottleneck, it is impossible at utmost meet user writable bandwidth demand, and optimization of network performance
Space is little.
(2) without NAS VM patterns
Fig. 2 is the Organization Chart without NAS VM patterns of prior art, as shown in Fig. 2 under this architecture, user provides itself
Virtual router 22 under project；System is by the port of routing device 23 of storage inside network and the port of user's virtual router 22
Interconnection, makes user virtual machine 21 be directly connected to storage inside network；By the direct carry rear end storage file of user virtual machine 21
System 24 is used.
There is following drawback in the cloud platform NAS patterns shown in Fig. 2：NAS virtual machines are not provided inside cloud platform, directly by after
End storage is exposed to user, is used by the direct carry of user.Under this pattern for directly providing storage service, due to will be internal
Memory node is directly exposed to user, can cause than more serious potential safety hazard.
The content of the invention
Internet resources cannot be made full use of in order to solve existing NAS services, it is impossible at utmost meet user writable bandwidth

The same rear end storage file system directory of the carry of virtual machine 40 is local to NAS virtual machines, is serviced as nfs server or CIFS
Device, service is externally provided by NFS or CIFS.All NAS virtual machines 40 provide service using public IP to user, feel user
Know less than there are many NAS virtual machines inside distributed NAS system.
Agency service is run on the upper strata of NAS virtual machines 40, user virtual machine 10 initiates carry request, and proxy server 30 connects
It is scheduled after receiving carry request, the carry request of different clients is distributed to different NAS virtual machines 40, by what is selected
NAS virtual machines provide storage or download service to the user belonging to corresponding client.Ideally, distributed NAS system
The all NAS virtual machines maximum bandwidth sums in the external a width of inside of maximum service band.
The embodiment of the present invention additionally provides a kind of distributed NAS methods, applies in cloud platform and based on said system reality
It is existing, as shown in figure 5, the method is comprised the following steps：
Step S501, proxy server receives the carry request that client is initiated, wherein, proxy server is connected to multiple
NAS virtual machines multiple NAS virtual machines are connected with client virtual machine, and are connected by routing device and rear end storage file system
Connect.In this step, multiple NAS virtual machines can be that cloud platform is created in multiple calculate nodes respectively.
The carry request of different clients is distributed to different NAS virtual machines by step S502, proxy server, by selecting
NAS virtual machines as file system server to corresponding client provide storage or download service.In the present embodiment, text
Part system server can be nfs server or CIFS servers, and proxy server uses poll or the mode pair of load balancing
Carry request is distributed.
In the method for above-described embodiment, based on the rear end sharable characteristic of storage file system, in different calculate nodes
On be respectively created NAS virtual machines, and be connected to same rear end storage file system, multiple NAS virtual machines are provided user simultaneously
Service, an external expose portion serve port, so as to ensure internet security.Meanwhile, in NAS virtual machines upper strata operation agency's clothes
Business, the request of user's carry is distributed on different NAS virtual machines, carries out distributed treatment, can make full use of Internet resources,
At utmost meet user writable bandwidth demand.Ideally, all NAS virtual machine services bandwidth sums are cloud platform point
The external maximum service bandwidth of cloth NAS system.
Specifically, NAS virtual machines provide NFS service using public IP to corresponding client, feel user
Know less than there are many NAS virtual machines inside distributed NAS system.System service in the present embodiment can include storage, under
Load, inquiry, rights management etc. are serviced.
Multiple equal carry rear end storage file system directories of NAS virtual machines are local to NAS virtual machines, are achieved in multiple
NAS virtual machines are connected by routing device with rear end storage file system, and NAS virtual machines can provide the user service, storage
File is to rear end storage file system or from rear end storage file system downloads file.
Client includes：User virtual machine and user's virtual router, user's virtual router are connected to user virtual machine.
Accordingly, proxy server receives the carry request that user virtual machine is initiated by user's virtual router.
Before proxy server receives the carry request that client is initiated, the above method also includes：Cloud platform is NAS empty
Plan machine creates the first Microsoft Loopback Adapter, and by the port binding of the first Microsoft Loopback Adapter and user's virtual router, make NAS virtual machines with
User virtual machine is connected；Cloud platform is the Microsoft Loopback Adapter of NAS virtual machine creatings second, and by the second Microsoft Loopback Adapter and routing device
Port binding, makes NAS virtual machines be connected with rear end storage file system.
In sum, above-mentioned distributed NAS method and system are optimized to the network performance of cloud platform NAS, are improve
NAS services maximum bandwidth.
