In an information processing system including a resource possibly shared between a plurality of work loads, an additional load is applied to the resource while operating the work loads, and the performances of the work loads are monitored. ## Claims ### Claim 1 An operation management method for an information processing system including a first resource connected to a first information processing apparatus and to a second information processing apparatus, wherein: an operation management computer of the information processing system applies an additional load to the first resource while operating a first combination of work loads including a first work load and a second work load in which the first work load is operated on the first information processing apparatus and the second work load is operated on the second information processing apparatus; and the operation management computer performs first monitoring on performance of at least one of the first work load and the second work load. ### Claim 2 (depends on 1) The operation management method for an information processing system according to claim 1, wherein the operation management computer determines allocation of the first combination to the first information processing apparatus and the second information processing apparatus based on a result of the first monitoring. ### Claim 3 (depends on 1) The operation management method for an information processing system according to claim 1, wherein: the operation management computer further applies an additional load to the first resource while operating a second combination of work loads including a third work load and a fourth work load in which the third work load is operated on the first information processing apparatus and the fourth work load is operated on the second information processing apparatus, and performs second monitoring on performance of at least one of the third work load and the fourth work load; and based on results of the first monitoring and the second monitoring, the operation management computer determines allocation of the first combination and the second combination to the first information processing apparatus and the second information processing apparatus. ### Claim 4 (depends on 1) The operation management method for an information processing system according to claim 1, wherein: the information processing system further includes a second resource shared between a third information processing apparatus and a fourth information processing apparatus; the operation management computer further applies an additional load to the first resource while operating a second combination of work loads including a third work load and a fourth work load in which the third work load is operated on the first information processing apparatus and the fourth work load is operated on the second information processing apparatus, and performs second monitoring on performance of at least one of the third work load and the fourth work load; and based on results of the first monitoring and the second monitoring, the operation management computer determines allocation of the first combination and the second combination to the first information processing apparatus, the second information processing apparatus, the third information processing apparatus, and the fourth information processing apparatus. ### Claim 5 (depends on 1) The operation management method for an information processing system according to claim 1, wherein the information processing apparatus is a server device, and the first resource is a network device. ### Claim 6 (depends on 5) The operation management method for an information processing system according to claim 5, wherein the network device is a network switch. ### Claim 7 (depends on 5) The operation management method for an information processing system according to claim 5, wherein the network device is a storage area network switch. ### Claim 8 An operation management method for an information processing system including a resource possibly shared between work loads, wherein: an operation management computer of the information processing system applies an additional load to the resource while operating a first work load in the information processing system; and the operation management computer performs first monitoring on performance of the first work load. ### Claim 9 (depends on 8) The operation management method for an information processing system according to claim 8, wherein: the operation management computer applies an additional load to the resource while operating a second work load in the information processing system, and performs second monitoring on performance of the second work load; and based on results of the first monitoring and the second monitoring, the operation management computer determines allocation of the first work load and the second work load in the information processing system. ### Claim 10 An information processing system including a first resource connected to a first information processing apparatus and to a second information processing apparatus, the system comprising: an operation management computer configured to apply an additional load to the first resource while operating a first combination of work loads including a first work load and a second work load in which the first work load is operated on the first information processing apparatus and the second work load is operated on the second information processing apparatus, and perform first monitoring on performance of at least one of the first work load and the second work load. ### Claim 11 (depends on 10) The information processing system according to claim 10, wherein the operation management computer determines allocation of the first combination to the first information processing apparatus and the second information processing apparatus based on a result of the first monitoring. ### Claim 12 (depends on 10) The information processing system according to claim 10, wherein: the operation management computer further applies an additional load to the first resource while operating a second combination of work loads including a third work load and a fourth work load in which the third work load is operated on the first information processing apparatus and the fourth work load is operated on the second information processing apparatus, and performs second monitoring on performance of at least one of the third work load and the fourth work load; and based on results of the first monitoring and the second monitoring, the operation management computer determines allocation of the first combination and the second combination to the first information processing apparatus and the second information processing apparatus. ### Claim 13 (depends on 10) The information processing system according to claim 10, wherein: the information processing system further includes a second resource shared between a third information processing apparatus and a fourth information processing apparatus; the operation management computer further applies an additional load to the first resource while operating a second combination of work loads including a third work load and a fourth work load in which the third work load is operated on the first information processing apparatus and the fourth work load is operated on the second information processing apparatus, and performs second monitoring on performance of at least one of the third work load and the fourth work load; and based on results of the first monitoring and the second monitoring, the operation management computer determines allocation of the first combination and the second combination to the first information processing apparatus, the second information processing apparatus, the third information processing apparatus, and the fourth information processing apparatus.
