Title:
外気冷却および局所冷却式情報処理システムとその負荷割当て方法
Document Type and Number:
Japanese Patent JP5921461
Kind Code:
B2
Abstract:
There are provided a practical open air cooled information processing system in which a back stream or recirculation of cooling air does not occur, as well as a load allocation method in such system. A temperature sensor (105) is provided in the cooling air inlet of each server (13). When increasing the number of servers (13) in operation, checking out which one of servers (13) out of operation, when activated, brings a results of minimizing a maximum value of the intake air temperatures of servers (13) in operation and then activating the one of the servers (13) are performed. Inversely, when decreasing the number of servers (13) in operation, deactivating a server (13) activated last is performed. It is avoided that, due to utilizing consolidation and using cooling equipment that takes in open air together, a back stream or recirculation of cooling air occurs, resulting in a fault such as an abnormal intake air temperature of a certain server (13).
