Security also includes the risk of PC information leakage and the risk of erasing data when a PC failure occurs. Corresponding to various work styles, various work styles such as telecommuting and shift work, etc. There is. In addition, a PC environment that does not change to an in-house PC is desired even for a mobile PC.

  Conventionally, with the increase in client PCs, there has been a problem that operation management according to the life cycle has become a heavy burden.

  Therefore, as one of the operation management methods of the client PC that reduces the operation management burden, a desktop virtualization system (VDI: Virtual Desktop Infrastructure) has been proposed by the present applicant.

  According to such a system, the operation management of the client PC described above can be performed efficiently, and high security or various work styles can be handled.

  Desktop virtualization in a desktop virtualization system is a mechanism for operating multiple clients in a server virtual environment and transferring the user interface to the hardware at hand of the user. Security can be improved by combining with a thin client.

  In addition, the desktop virtualization system includes means for automatically generating a virtual desktop from the master (master template) according to the scale of the client. By this means, a virtual machine is added (automatically) to the server. New PC procurement and its network setting can be omitted, and even if a failure occurs on the client side, the problem of the failure can be solved by re-login from another client.

  In other words, the client management cost can be reduced and the security can be improved by centrally managing the clients by desktop virtualization.

Will be described with reference to FIG.

  In the figure, first, TCO prediction value trial calculation processing is performed in steps S3000 to S3003. That is, the process starts in step S3000. First, in step S3001, for example, PC / VDI (Personal Computer / Virtual Desktop Infrastructure) initial parameters shown in FIGS. 3 and 4 are input from the initial input parameter interface 3011 of the data acquisition server 301.

  These input parameters (input data) are stored in the PC initial parameter table (see FIG. 6) and the VDI initial parameter table (see FIG. 7) of the input DB 3014.

Next, in step S3002, the TCO trial calculation unit (TCO trial application) 3021 of the TCO trial calculation server 302 executes TCO trial calculation processing based on information in the PC / VDI initial value parameter table of the input DB 3014 to obtain a predicted value. .
The trial calculation process result (predicted value) is output to the portal site server 303 in step S3003, and the portal site server 303 posts the TCO trial calculation result (predicted value).

  As an example of output to the portal site server 303 and posting on the portal site, as shown in FIG. 17 or FIG. FIG. 17 shows a client and desktop virtualization as a bar graph, and FIG. 18 shows a line graph, each of which visually performs a TCO reduction effect.

  After the above steps, after designing and building a desktop virtualization system, the system is introduced in step S3004.

Next, after obtaining the predicted TCO value, the actual TCO value is obtained in steps S3011 and S3012.
First, in step S3011, processing for automatically calculating the operation work man-hour from the information of the event DB that records the operation work man-hour and the operation log of the VDI system from the time of the operation work performance interface 3012 (FIG. 5) is performed.

  That is, the work start / end time is extracted from the operation work result interface 3012, and calculation formula 1 ([VDI work time table] D002-D001) and calculation formula 2 ([VDI work time table] E002-E001) are obtained from these times. Thus, the VDI operation man-hour is calculated, and this calculated man-hour is stored in the VDI operation man-hour table (see FIG. 12) of the input DB 3014.

  Next, the work start / end time is extracted from the event database 2013 of the desktop virtualization system, and the VDI system-operating man-hour is calculated from these times by the calculation formulas 1 and 2, and this calculated man-hour is calculated as the VDI system- of the input DB 3014- It is stored in the operation man-hour table (see FIG. 15).

  Next, in step 3012, a TCO trial calculation process (actual value) is performed by the TCO trial calculation unit (TCO trial calculation application) of the TCO trial calculation server 302.

  That is, the work time is calculated based on the information in the VDI work time table (see FIG. 11) in the input DB 3014. Based on the calculated work time, an amount is calculated by calculation formula 3 ([VDI initial parameter table] C002 * D003) and calculation formula 4 ([VDI initial parameter table] C002 * E003), and this amount is used in VDI operation. Store in the cost table (see FIG. 13).

  Subsequently, based on the information in the VDI initial parameter table (see FIG. 7) and the VDI operation man-hour table (see FIG. 12), Formula 5 ([VDI initial parameter table] C002 * [VDI system-operation man-hour table] J003 ), The operation cost is calculated by Formula 6 ([VDI initial parameter table] C002 * [VDI system-operation man-hour table] K003), and the operation cost is stored in the VDI system-operation cost table (see FIG. 16).

  Next, based on the information in the PC initial parameter table (see FIG. 6), the VDI actual parameter table (see FIG. 8), and the VDI operating cost table (see FIG. 12), the TCO trial calculation unit (TCO trial application) of the TCO trial server 302 ) To calculate TCO. The trial calculation result (actual value) is output to the portal site server 303 and posted on the site.

17 and 18 show examples of output to the site.
In FIG. 17, the client (FAT client) and the desktop virtualization TCO are compared with a bar graph to display the initial introduction cost, the operation management cost, the TCO reduction effect, and the predicted value and the actual value are displayed in comparison with each other. Is shown.

  In FIG. 18, a line graph is used for comparison, and a TCO comparison result and a table for visually confirming the TCO reduction effect are displayed. However, it is not necessary to limit to these display forms.

  Next, in step S3013, the TCO trial calculation result (predicted value) calculated in step S3002 is compared with the TCO trial calculation result (actual value) calculated in step S3012, and it is determined how much the difference between these trial calculation results is.

  As a result, if the difference in the trial calculation results exceeds ± 3%, for example, in step S3014, the manager of the visualization system is notified through the communication terminal such as e-mail through the administrator terminal, and in step 3015, the cause of the difference Analyze.

  This analysis is performed as follows. The top three of all costs are extracted from the work items actually operated (from the VDI operation cost table of the input DB 3014). A breakdown of work items is extracted from the extraction result (from the VDI operation man-hour table and VDI operation cost table of the input DB 3014). From this extraction result, the bottleneck portion is output, and the administrator can check the bottleneck portion via the manager terminal.

  If it is within ± 3% in step S3013, the process proceeds to step S3016.

  The TCO estimation result at this time is output to the portal site server 303 in step S3016 and posted on the site.

  Through these steps, the desktop virtualization system is operated in step S3017. This operation returns to step S3011, is repeatedly executed, and ends at step S3018.

  According to the embodiment described above, the TCO reduction effect by desktop visualization can be easily confirmed. Thereby, it is possible to expect a better operational cost for the client.

  Any system can be applied as long as it is a system that is responsible for the operation work of the manager and that wants to visualize the TCO reduction effect combined with the work results.
