Description
Technical field
The present invention relates to computer software technical field, particularly, relate to a kind of between different hardware platforms the method for cloning software system, wherein by clone that the computer with different hardware platforms in the group of planes is divided into groups, between different hardware platforms, realize the clone of software systems.
Background technology
In application number is 200510074620.0 patent application document, a kind of method that realizes the network clone between the little computer of hardware platform difference is disclosed, its realization flow as shown in Figure 1, but for platform chip situation about causing diversified in specifications, this method also still can't solve the problem that receiving end computer can't normally start after the simultaneous interpretation, reason is that the driver that operates in core layer must mate fully with hardware information, operating system could be finished the work that kernel starts smoothly, otherwise will start the Logon process that enters operating system, thereby the driver intelligence installation function that also just can't continue to call the startup group removes the drive information of upgrading hardware, if such as the CPU on the source computer is Intel Company, and the CPU on the object-computer is an AMD, and target machine restarted and will occur when entering operating system crashing after the network clone finished so.Therefore each PC producer still takes the measure evaded so far, requires the user to dispose same batch of computer in Public Computer Room.
Yet, in the product line running and big customer's buying pattern of reality, be difficult to guarantee not occur in certain product line the mainboard of two kinds of specifications, and these two kinds of product types also are difficult to assurance and do not issue in same end user's hand, such as Education Commission's centralized purchasing in certain city 10,000 All-China Federation of Taiwan Compatriots think Qitian Computer, distribute to each school then successively, but because a so big order can be divided into a plurality of batches of delivery at different time phases in practical operation, therefore while arrival " Qi Tian 4210 " and " Qi Tian 6210 " in the same electronic classroom just appears inevitably, what suppose " Qi Tian 4210 " use is Intel CPU+Intel 845GV mainboard, what used " Qi Tian 6210 " is AMD CPU+VIA KM400 mainboard, clearly after " Qi Tian 4210 " last ready-made system is cloned on " Qi Tian 6210 ", may can't start by blank screen when restarting computer, because the hardware structure difference of these two platforms is too big.
This demand that realizes system deployment quickly and easily between the very large computer of hardware platform difference is increasing, and this demand is very strong for the keeper of those bigger Public Computer Room (surpass such as number of computers 100 Internet bar).
For by long-range technology of giving computer installing operating system and application software comparative maturity (below be referred to as " long-range Installation Modes "), mainly be exactly to utilize PXE (pretrigger environment) agreement of having supported in the computer BIOS, and the automatic installation function based on the script describing language of operating system installation program support itself, operating system installation catalogue on the control end computer is invented a local directory, the beginning automatic installing operating system, in this manner, what adopt between transmitting terminal and the receiving end computer is connection-oriented network data transmission agreement, therefore the receiving end computer quantity that is connected simultaneously with the transmitting terminal computer is many more, transmitting terminal network card data flow is just big more, taking of cpu resource and memory source is just many more, thereby can form a performance bottleneck.
In addition, also have a kind of mixing Installation Modes, under this pattern, specify a transmitting terminal computer in advance in a group of planes, other computers in the group of planes become receiving end computer with respect to this transmitting terminal computer.Then, adopting above-mentioned long-range Installation Modes is transmitting terminal computer install software system in the group of planes, then, it is the interior computer cloning software system of the same physics network segment that this transmitting terminal computer uses the broadcasting mounting means, that is, the transmitting terminal computer sends to receiving end computer by broadcast mode with the software systems installation file in this machine and controls the installation of these software systems.Here it is described mixing Installation Modes wherein mixes and has used long-range Installation Modes and broadcasting Installation Modes.But, in the method, be faced with the problem that can not thoroughly support to stride hardware platform.
Do a simple mathematical and calculate the order of severity that just can find out this bottleneck effect, suppose only need a WindowsXP be installed from long-range each receiving end computer of giving, total data capacity is about 1.7G, the set-up time of WindowsXP is about 30 minutes, needs were from installing copies data on the medium in nearly 10 minutes, therefore 1 receiving end computer of every installation is 85M byte/min to the averaging network load of transmitting terminal computer, be equivalent to 2.27M bit/s, this is the valid data loading index, in fact add some control informations and fault-tolerant retransmission of information, the real data loading index can be than the high 10%-30% of valid data loading index, calculating real data load result with mean value 20% is 2.712M bit/s, calculate like this, for the transmitting terminal computer that is equipped with the 100M network interface card, when giving 35 following receiving end computer installing operating systems simultaneously, performance index can obviously not descend, if but think to give simultaneously 50 even 100 receiving end computer installing operating systems, installation rate will sharply descend so, because also will consider cpu resource in the transmitting terminal computer, the use bottleneck effect of memory source and I/O resource.Therefore use the method for this connection-oriented long-range installing operating system and driver that very big limitation is also arranged.
Therefore, give the demand of 50 the quick deployment operation of above computer systems for striding hardware platform, merely use the clone technology of duplicating based on the broadcast packet agreement, perhaps merely using all can't be satisfied fully based on the long-range mounting technique of connection oriented protocol, need find better solution.
Usually can both be arranged in the same physics network segment at computer in the Public Computer Room, all computers are all provided by same supplier, the hardware configuration of most of computer is identical, the discrepant concrete situation of hardware configuration meeting of having only the only a few computer, need in conjunction with utilizing the existing clone technology of duplicating based on the broadcast packet agreement, hardware configuration differentiation comparison techniques, long-range mounting technique based on connection oriented protocol, driver intelligence mounting technique and software dispatch technology, design a specific mounting strategy and algorithm, thereby realization is the computer installing operating system in the whole Public Computer Room the most quickly and easily, driver and application software.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described.Fig. 2 shows the overview flow chart of the method for cloning software system between different hardware platforms according to the embodiment of the invention.
After the keeper connects into the computer in the group of planes of Public Computer Room physically in a network segment, as shown in Figure 2, select a computer to be used as transmitting terminal arbitrarily, start the state (step 200) of preparing to carry out the network clone that enters; Then, remote activation or wake other receiving end computers up, allow them enter into login transmitting terminal state (step 202), next, receiving end computer is checked the hardware configuration information of self, and send it to transmitting terminal computer (step 204) with specific format, after the hardware configuration information that receives from each receiving end computer, the transmitting terminal computer compares oneself hardware configuration information and these hardware configuration informations, and according to comparative result to receiving end computer divide into groups (step 206), at last, the transmitting terminal computer is given every sets of computer install software system (step 208) according to different strategies.
Fig. 3 shows the flow chart according to the processing of dividing into groups to receiving end computer of the embodiment of the invention.
As shown in Figure 3, in fact, relatively the method for hardware configuration information has two kinds, and a kind of is at PCI equipment, can obtain the information of certain PCI equipment according to the regulation in the PCI standard, compares its id information then; Another kind is at non-PCI equipment, directly goes to obtain such as BIOS file name and version information such as hard disk model and capacity from BIOS.As example, only compare the PCI facility information in the present embodiment, and only be divided into two groups in view of the above.In step 330, according to the PCI facility information, the consistent still inconsistent receiving terminal of supplier information (VendorID) with identical receiving end computer of described transmitting terminal computer or hardware chip specification (DeviceID) of hardware configuration information is included in first group, note its MAC Address of Network Card respectively, so that in follow-up is mutual, use.Next,, hardware chip specification and supplier information all are included into the second sets of computer group with the inconsistent receiving end computer of transmitting terminal, write down their MAC Address of Network Card respectively, so that in follow-up is mutual, use in step 332.
Below with reference to Fig. 4, Fig. 4 shows according to the detail flowchart of Different Strategies for the processing of each sets of computer install software system.
As shown in Figure 4, select first sets of computer (step 400) according to group result, begin to read the valid data piece (step 402) on the transmitting terminal hard disk, wherein said data block comprises software system information.Then, use the broadcast data packet method that this data block is sent to receiving end computer (step 404), after each receiving end computer receives this data block, it is write the correspondence position (step 406) of hard disk, then, judge and whether also have valid data (step 408) in the transmitting terminal hard disk, if (step 408, "Yes"), then repeats said process, until all valid data on the transmitting terminal hard disk all are sent out away, promptly if not (step 408, "No"), after then each receiving terminal in first sets of computer is received total data and write hard disk, just oneself shut down (step 410).At this moment, all installations of each computer in first sets of computer (comprising transmitting terminal and receiving end computer).
Then, the transmitting terminal computer is selected second sets of computer (step 412), be divided into son group (step 414) with all computers in second sets of computer according to the identical condition of hardware configuration this moment, promptly, (for example will have the same hardware platform, have identical chips specification and supplier information) computer be divided into one group, thereby form the identical child group of a plurality of hardware platforms.Under cluster environment, usually, after having divided first sets of computer, can there be the different child group of many hardware configuration in second sets of computer, this is owing to actual purchase computer in machine room will consider these problems.Therefore, second sets of computer is divided into after the son group, in practice, only can has two to three son groups usually.
Next, to the computer application mounting strategy (step 416) in each height group.At this moment, can specify one of the long-range Installation Modes of application and mixing Installation Modes (as mentioned above) to install, also can select to install according to required time is installed with a kind of pattern of selecting required set-up time minimum in long-range Installation Modes and the mixing Installation Modes.To be described in detail a kind of selection mode in back below.
Fig. 5 shows according to the long-range Installation Modes of the selection of the embodiment of the invention and mixes the flow chart of Installation Modes with the method for installing.
As shown in Figure 5, after beginning, required set-up time T1 calculates (step 510) to long-range Installation Modes, and calculates (step 520) 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 530), 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 540); Otherwise, then select long-range Installation Modes to come cloning software system (step 550).
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 terminal 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 computer of independent long-range installation, the average speed 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 computer that hard disk is changeed in P4 CPU+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 computers.M represents the platform number of computer 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 computers 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 computer 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. 6.
Next the computational 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 total time T21 that uses long-range Installation Modes to give a transmitting terminal computer (as mentioned above) install software system in this group of planes; Calculating uses the broadcasting Installation Modes to give the total time T22 of other receiving terminal install software systems in this group of planes by described transmitting terminal computer; 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:
Computational methods 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 compression ratio/V broadcasting
Wherein the R compression ratio is the mean pressure shrinkage index of the data compression algorithm of clone's program employing itself, and number range can arrive 0.6 such as the good R compression ratio 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 computer 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. 7 by application software basis computer profile at that time.
It should be noted that 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 computer 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.
