As new servers have been introduced and installed in a computer room which already has various servers, many problems, such as a lack of room space, a lack of rack space, and a rise in power consumption, have arisen. The increasing number of operators and rising cost of maintenance caused by the problems lead into a rise in IT expenditure for the computer room. To solve the problems, server integration & virtualization technology, which is used to save power consumption and space and reduce maintenance cost, has gradually been expanding. In this paper, old six UNIX servers were integrated into two in the virtualization process of UNIX servers, in which one partition (DLPAR) per server was created, and more than three DB instances were generated in the created partition for DBMS. As a result, multiple physical servers were made as integrated virtualization servers which ended up solving the space problem in a computer room, securing a rack space and increasing the efficiency of a thermo-hygrostat. More specifically, the server integration & virtualization process brought about the following saving rates: 72% of rack space (U) in a computer room, 90% of power (W), and 59% of cooling (BTU).
