Be stored into again in corresponding memory device after the data content that operation system will store is encrypted.
Based on the virtualized storage device of above-mentioned virtualization storage method, it is characterized in that: its interface comprises business end and stores end; Described business end is connected with each operation system, provides virtual NAS and SAN stores service to operation system; Described storage end is connected with each memory device, provides actual SAN stores service by memory device; Also comprise,
Memory device Attribute Recognition module, identifies the memory attribute of each memory device connected;
Data acquisition module, intercepts and captures the data that each operation system will store;
Data storage attribute identification module, identifies that the data that will store need the stores service attribute provided;
Storage device allocation module, needs the stores service Attributions selection provided to meet the memory device of stores service attribute according to the data that will store of current identification;
Data transmission blocks, the data that will store are sent to the memory device that will deposit;
Described memory attribute comprises capacity and the speed of memory device.
Also comprise configuration data library module, need the stores service property store provided in configuration database each operation system.
Also comprise encrypting module, the data that will store that data interception module is intercepted and captured are encrypted.
Described business end is connected with each operation system by switch; Described storage end is connected with each memory device by mutual machine.
Based on the virtualization storage method of above-mentioned virtualized storage device, it is characterized in that: the memory attribute service that each memory device can provide according to it provides to virtualized storage device with the form of COS; Described virtualized storage device provides virtual LUN to operation system, operation system connects the virtual LUN provided, data are written in virtual LUN by standard agreement, virtualized storage device identification will store the stores service attribute that data need to provide, and the data that will store are stored in actual memory device.
Virtualized storage device identifies by the configuration database that self stores the stores service attribute that this operation system needs to provide, and the data that will store are stored in actual memory device.
Described method also comprises: virtualized storage device is stored into physical storage devices after being encrypted the data content that will store after intercepting the data that operation system will store again.
For field of data storage, cryptographic technique and storage virtualization technology is used to be stored in memory device by after operation system data encryption; To the memory device of the various framework in business shielding rear end, storage resources is carried out Chi Huahou to provide with service form simultaneously.
Compared with prior art, the invention has the beneficial effects as follows:
1, by the expansion to NAS, SAN agreement, form virtual memory facilities and be supplied to front-end business, adapter stores service.Whole process is completely transparent to business, and business is without the need to changing.
2, use storage virtualization technology, abstract integration is carried out to back-end physical storage volume, can require to distribute according to (capacity, speed etc.) physical storage volume according to user.
3, allow dynamically to increase memory device when business is online.Business is to the adjustment unaware of storage hardware equipment.
4, allow to use the memory device of variety classes different manufacturers as unified physical storage medium, avoid the adaptive multiple heterogeneous storage devices of operation system.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the present invention's wherein embodiment.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Arbitrary feature disclosed in this instructions (comprise summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Virtualized storage device as shown in Figure 1, is characterized in that: its interface comprises business end and stores end; Described business end is connected with each operation system, provides virtual NAS and SAN stores service to operation system; Described storage end is connected with each memory device, provides actual SAN stores service by memory device; Also comprise,
Memory device Attribute Recognition module, identifies the memory attribute of each memory device connected;
Data acquisition module, intercepts and captures the data that each operation system will store;
Data storage attribute identification module, identifies that the data that will store need the stores service attribute provided;
Storage device allocation module, needs the stores service Attributions selection provided to meet the memory device of stores service attribute according to the data that will store of current identification;
Data transmission blocks, the data that will store are sent to the memory device that will deposit;
Described memory attribute comprises capacity and the speed of memory device.
Also comprise configuration data library module, need the stores service property store provided in configuration database each operation system.
Also comprise encrypting module, the data that will store that data interception module is intercepted and captured are encrypted.
Described business end is connected with each operation system by switch; Described storage end is connected with each memory device by mutual machine.
Operation system A requires high speed storing service, and business B requires Large Copacity and high speed storing, and business C requires that storing data needs backup.Storage characteristics is as follows: store A, B be high speed storing but the less and data of capacity without backup, store C belong to low speed storage but data backup function is provided, conventional coupling arrangement needs business A to connect storage A or B, business B and connects storage A and B, business C connection storage C simultaneously.First all business must consider the agreement storing A, B, C use when connecting and storing, speed, capacity etc., to service management require higher and when separate unit storages cannot meet the demands (as business B) cannot connect when not changing business configuration multiple stage storage.
