Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Consulting shown in Fig. 1, is the applied environment figure of internal storage management system 10 preferred embodiments of the present invention.This internal storage management system 10 is applied to privately owned Cloud Server 1, and multiple cloud clients 3 are connected to this privately owned Cloud Server 1 by network 2, shares the service that privately owned Cloud Server provides.This internal storage management system 10 distributes fixed address space in physical memory 20 for each cloud client 3, avoids the same address space in the application program access physical memory 20 of different cloud clients 3.
Consulting shown in Fig. 2, is the functional block diagram of internal storage management system 10 preferred embodiments of the present invention.These internal storage management system 10 first receiver modules 11, memory allocating module 12, the second receiver module 13 and address conversion module 14.Module 11-14 comprises computer programing instruction, these computer programing instructions are stored in the default address space of the memory 30 of privately owned Cloud Server 1, the processor 40 of privately owned Cloud Server 1 is carried out these computer programing instructions, and the above-mentioned functions of internal storage management system 10 is provided.Below in conjunction with the concrete function of Fig. 3 specification module 11-14.
Consulting shown in Fig. 3, is the flow chart of EMS memory management process preferred embodiment of the present invention.
Step S10, the first receiver module 11 receives cloud client 3 asks privately owned Cloud Server 1 to specify the request in the first capacity physical memory space.For example, the first receiver module 11 receives First cloud client 3 asks privately owned Cloud Server 1 to specify the request in 500MB physical memory space, receives second cloud client 3 and asks privately owned Cloud Server 1 to specify the request in 400MB physical memory space.
Step S20, memory allocating module 12 is that this cloud client 3 is specified the fixed address space that meets the first capacity in physical memory 20.For example, memory allocating module 12 is First cloud client 3 starts to distribute 500MB in physical memory 20 address space 0x00001000 ~ 0x******* from physical address 0x00001000, is second cloud client 3 starts to distribute 400MB in physical memory 20 address space from physical address 0x******.
Step S30, the second receiver module 13 receives the request of asking to distribute the second capacity internal memory when this cloud client 3 runs application.
Step S40, address conversion module 14 is the virtual memory of the second capacity described in the application assigned of this cloud client 3, the address space of virtual memory is converted to the described fixed address space of physical memory 20.For example, suppose that run application A request of First cloud client 3 distributes the memory headroom of 480MB, the B request that runs application of second cloud client 3 distributes the memory headroom of 450MB, address conversion module 14 is the virtual memory space of application A distribution 480MB, the virtual memory space of this 480MB is converted to the fixed address space 0x00001000 ~ 0x******* of physical memory 20.Address conversion module 14 is the virtual memory space of application program B distribution 450MB, and the virtual memory space of this 450MB is converted to the address space that starts the 400MB distributing in physical memory 20 from physical address 0x******.
Step S50, address conversion module 14 judges whether the described fixed address space of physical memory 20 can meet the demand of virtual memory.If can meet the demand of virtual memory, move the application program of this cloud client 3, flow process enters step S70 afterwards.For example, the application A of First cloud client 3 needs the memory headroom of 480MB, and First cloud client 3 is specified the fixed address space that has 500MB in physical memory 20, if can meet the demand of application A.If the described fixed address space of physical memory 20 can not meet the demand of virtual memory, perform step S60.For example, second cloud client 3 B that runs application needs the memory headroom of 450MB, and the fixed address space that second cloud client 3 specified in physical memory 20 only has 400MB, also poor 50MB.
Step S60, address conversion module 14 is divided part address space make-up virtual memory from memory 30.For example, address conversion module 14 is divided the supplementary virtual memory of address space of 50MB from memory 30.This memory 30 can comprise hard disk, flash memory disk etc.
Step S70, releasing memory after the application program end of run of this cloud client 3.For example, after application A end of run, discharge the memory headroom of its 480MB taking in physical memory 20; After application program B end of run, discharge the memory headroom of its 400MB taking in physical memory 20, and discharge the address space of its 50MB taking in memory 30.In other embodiments, this EMS memory management process also can not comprise step S70.
Need to illustrate, EMS memory management process provided by the invention also can be applied to publicly-owned cloud and mixed cloud.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to above preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
