System layout decisive system, system layout decisive manner and program

摘要

The system layout decisive system which can decide the appropriate quantity which satisfies the availability which is decided with SLA as a quantity of the information processing equipment which is used with the system of the construction target, is offered. List generation means 52 generate the list of the information processing equipment whose failure rate is lower than the failure rate which is stipulated at least, the information processing equipment whose cost is lowest, is independently used, or, the information processing equipment group which forms the cluster is searched. The information processing equipment where it calculated the quantity of the information processing equipment which is necessary in order the normal time to fill up the required throughput the information processing equipment where quantity decisive means 53 were searched and are used independently, or, on the basis of with the throughput of the information processing equipment group which forms the cluster and the normal time the required throughput, was searched and is independently used, or, with the information processing equipment group which forms the cluster, in condition, it decides that quantity can be guaranteed as the quantity of the information processing equipment which uses that quantity, with the construction target system.
