Description of drawings
Below in conjunction with the detailed description of preferred embodiment that accompanying drawing adopted, above-mentioned purpose of the present invention, advantage and feature will become apparent by reference, wherein:
Fig. 1 shows the overview flow chart according to the method for the cloning software system of the embodiment of the invention;
The form of the V separate unit copy empirical value that is provided by manufacturer is provided Fig. 2; And
The form of the V broadcasting empirical value that is provided by manufacturer is provided Fig. 3.
Embodiment
Describe the preferred embodiments of the present invention below with reference to the accompanying drawings in detail.
Fig. 1 shows the overview flow chart according to the method for the cloning software system of the embodiment of the invention.
As shown in Figure 1, after beginning, required set-up time T1 calculates (step 110) to long-range Installation Modes, and calculates (step 120) to mixing the required set-up time T2 of Installation Modes.Then, required set-up time T1 of long-range Installation Modes and the required set-up time T2 of mixing Installation Modes are compared (step 130), if the required set-up time T1 of long-range Installation Modes greater than mixing the required set-up time T2 of Installation Modes, then selects to mix Installation Modes and comes cloning software system (step 140); Otherwise, then select long-range Installation Modes to come cloning software system
(step 150).
As example, can adopt following formula to calculate T1:
T1=(T copy+T installation)
Wherein, T copy=int (M/ (bandwidth/V separate unit copy)) * (operating system installation file size/V separate unit copy);
In above formula, the implication of " T copy " is to need after installing operating system begins from transmitting terminal installation file to be copied to time the receiving end internal memory, so it depends on the network bandwidth, network interface card speed, memory read-write speed and R/W speed of hard disc.When wherein the implication of V separate unit copy is computing machine of independent long-range installation, the average velocity of copied files, it and CPU speed, memory size and rotation speed of hard disk relation are maximum, this numeric ratio is fit to test by experiment and obtains, the computing machine that hard disk is changeed in P4CPU+256M internal memory+7200 that is configured to for Intel, the size of V separate unit copy is about 3M/s, therefore if the system of 1.7G size is installed, the time of every copy is 1700/3 to approximate 570 seconds, and for the 100Mbps network, installation 100/ (3*8) that at every turn can walk abreast approximates 4 computing machines.M represents the platform number of computing machine in the group of planes, if therefore M equals 50, so just is equivalent to needs and divides int (50/4)=13 to install, and all T copy=13*570s=7410s approximate 124 minutes, have promptly surpassed two hours.
The implication of " T installation " is configuration operation system and driver to be installed (promptly from internal memory, software systems) time, the complexity that depends on operating system, because all computing machines can start installation process simultaneously in this group of planes, therefore T installs only needs calculating a, the T of WindowsXP was installed in about 30 minutes, so T311=124+30 approximates 154 minutes.
When computing machine dispatches from the factory; manufacturer goes out different numerical value according to the differentiating measurement of key hardware configuration; leave in the form among the HPA (host protecting region), go to seek in this table the immediate corresponding time of configuration by application software basis computer profile at that time.V separate unit copy empirical value has been shown in the form of Fig. 2.
Next the computation process of mixing the required set-up time T2 of Installation Modes will be described, particularly, this process is divided into following a plurality of step: calculate the T.T. T21 that uses long-range Installation Modes to give a transmitting terminal computing machine (as mentioned above) install software system in this group of planes; Calculating uses the broadcasting Installation Modes to give the T.T. T22 of other receiving end install software systems in this group of planes by described transmitting terminal computing machine; Obtain to mix the total set-up time T2=T21+T22 under the Installation Modes thus.
As example, can adopt following formula to calculate T21, T22:
Computing method and the T1 of T21 are similar, it should be noted that M wherein becomes 1 at this moment.
T22=operating system installation file size * R compressibility/V broadcasting
Wherein the R compressibility is the mean pressure shrinkage index of the data compression algorithm of clone's program employing itself, and numerical range can arrive 0.6 such as the good R compressibility of design between 0.5～1.0.
The implication of V broadcasting is similar to V separate unit copy, also main and CPU speed, memory size and the rotation speed of hard disk concern maximum, but its speed can be bigger than V separate unit copy, when computing machine dispatches from the factory, manufacturer goes out different numerical value according to the differentiating measurement of key hardware configuration, leave in the form among the HPA, go to seek in this table the immediate corresponding time of configuration, V broadcasting empirical value has been shown in the form of Fig. 2 by application software basis computer profile at that time.
It should be noted that above shown computing formula only is exemplary, can suitably change above-mentioned formula and calculate each time that this is conspicuous.In addition, described software systems can be that operating system, application program system and other need to install the system of (clone).And related in the present invention computing machine implication is sensu lato, and it can comprise the computing equipment that needs the install software system arbitrarily.
Although below show the present invention in conjunction with the preferred embodiments of the present invention, one skilled in the art will appreciate that under the situation that does not break away from the spirit and scope of the present invention, can carry out various modifications, replacement and change to the present invention.Therefore, the present invention should not limited by the foregoing description, and should be limited by claims and equivalent thereof.
