Abstract
The present invention relates to a kind of Storage Virtualization gateway New Virtual mapping method, this method is by the way that two volume mappings are recognized respectively to two Storage Virtualization gateway devices, two volumes are invented to applied host machine by a volume mapping by Storage Virtualization gateway device again, and Storage Virtualization gateway is mapped using unique virtual sequence number during mapping, so that applied host machine need to only be concerned about the volume used, the composition of rear end volume need not be concerned about, simultaneously when a Storage Virtualization gateway device or link break down, virtual sequence number can drift automatically, so that applied host machine perceives the change rolled up less than rear end, also without adjusted because of the change that rear end is rolled up configuration etc..
Description
Technical field
Patent of the present invention is related to computer field of storage.
Background technology
Storage Virtualization is a kind of through whole IT environment, for simplified underlying basis that originally may be relative complex
The technology of framework.The thought of Storage Virtualization is to separate the logical image of resource and physical store, so as to be systems and management
Member provides width simplification, seamless resource virtual view.
For a user, the storage resource of virtualization is like huge " storage pool ", and user not can be appreciated that tool
Disk, the tape of body, need not also be concerned about which specific storage device is the data of oneself lead to by which paths.
From the perspective of management, storage pool is the management for taking centralization, and according to specific demand storage
Resource is dynamically assigned to each application.It is worth it is emphasized that using virtualization technology, magnetic can be simulated with disk array
Tape pool, provides speed fast, capacity but storage resource big as tape library as disk, here it is applying now for application
More and more extensive VTL（VTL, Virtual Tape Library）, play in current enterprise storage system
More and more important role.
The same as pond using storing, memory space, can arbitrarily basis as the water in the pond of same flowing
Need to be allocated.
Storage Virtualization (Storage Virtualization) most popular understanding is exactly that storage hardware resource is carried out
Abstract is showed.By by one（Or it is multiple）Target（Target）Services or functionalities and other additional functions are integrated, unified
Useful full functionality service is provided.Typical virtualization includes the following situation：The complexity of shielding harness, increase or collection
Cheng Xin function, emulates, integrates or decomposes existing service function etc..Virtualization is to act on one or more physically
, and these entities are then for providing storage resource and/or service.
Patent of invention content
Patent of the present invention is related to a kind of Storage Virtualization gateway New Virtual mapping method, and this method is by the way that two volume mappings are given
Two Storage Virtualization gateway devices recognize respectively, then two volumes are invented into a volume by Storage Virtualization gateway device reflected
Penetrate to applied host machine, and Storage Virtualization gateway is mapped using unique virtual sequence number during mapping so that
Applied host machine need to only be concerned about the volume used, it is not necessary to the composition of rear end volume is concerned about, while in a Storage Virtualization gateway device
Or during link failure, virtual sequence number can drift automatically so that applied host machine perceives the change less than rear end volume, is also not required to
Configuration etc. is adjusted because of the change that rear end is rolled up.
Virtual sequence number and the real sequence rule that Storage Virtualization gateway is used are identicals, and virtual sequence number
It is globally unique, is created with the establishment of virtual volume, is destroyed with the destruction of virtual volume, can be in many outer Storage Virtualization gateway collection
Drift is carried out in group.
The virtual volume of Storage Virtualization gateway can by a variety of level of redundancy building form, this business to applied host machine connects
Continuous property is related to performance, but unrelated with the virtual sequence number of this method.
