Abstract
The present invention relates to a kind of memory virtualization system data processing implementation method, this method is applied in the storage device that memory virtualization system rear end has multiple performances different, can promote memory virtualization system overall performance responding ability.When this method initiates write request by data from business host, the metadata information of the first storage device is stored by memory virtualization system record data, when later stage is migrated due to data-triggered to the second storage device, it is the second storage device that memory virtualization system, which updates metadata information, when business host initiates data read request, metadata information is directed toward the second storage device and provides in memory virtualization system.
Description
Technical field
The invention patent relates to computer field of storage, especially Storage Virtualization field.
Background technology
Storage Virtualization (Storage Virtualization) most popular understanding is exactly to be carried out to storage hardware resource
Abstract performance.By by one（Or it is multiple）Target（Target）Services or functionalities are integrated with other additional functions, unified
Useful full functionality service is provided.Typical virtualization includes the following situation：The complexity of shielding harness increases or collects
The function of Cheng Xin 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.
Storage Virtualization be it is a kind of through entire IT environment, for simplify originally may be relative complex underlying basis
The technology of framework.The thought of Storage Virtualization is to separate the logical image of resource and physical store, to be systems and management
Member provides width simplification, seamless resource virtual view.For a user, the storage resource of virtualization is like one huge
" storage pool ", user not can be appreciated that specific disk, tape, need not be concerned about that the data of oneself are led to by which paths yet
Which specific storage device.From the perspective of management, storage pool is to take the management of 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 being used
Disk array analog tape library, provides that speed is fast as disk, capacity but storage resource big as tape library for application, this
It is exactly to apply more and more extensive Virtual Tape Library now（VTL, Virtual Tape Library）, stored in current enterprise
It is played an increasingly important role in system.
Storage is the same as pond, and memory space, can arbitrarily basis as the water in the pond of the same flowing
It needs to be allocated.By by one（Or it is multiple）Target（Target）Services or functionalities are integrated with other additional functions, system
One provides useful full functionality service.Typical virtualization includes the following situation：The complexity of shielding harness, increase or
Integrated new 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 service.
Patent of invention content
The invention patent relates to a kind of memory virtualization system data processing implementation method, this method is applied to Storage Virtualization system
In the storage device that system rear end there are multiple performances different, memory virtualization system overall performance responding ability can be promoted.The party
When method initiates write request by data from business host, the member of the first storage device is stored by memory virtualization system record data
Data information, when the later stage is migrated due to data-triggered to the second storage device, memory virtualization system update metadata information is
Second storage device, when business host initiates data read request, metadata information is directed toward second in memory virtualization system
Storage device provides.
