Abstract: A plurality of server computers shares a virtualized namespace. A storage controller provides a virtual storage area shared by a first server computer and a second server computer. A server computer that is each of the first server computer and the second server computer stores a program that issues an NVM-Express command that is a command conforming to an NVM-Express standard. The program allows the server computer to access the virtual storage area via the PCI-Express by issuing the NVM-Express command specifying a namespace associated with the virtual storage area. The storage controller allocates a storage area in a nonvolatile memory device to the virtual storage area based on the access.

Abstract: If multiple drive chassis, in a storage system, the inlet air temperature or operation amount differs greatly among the drive chassis, total fan power in the drive chassis and may increase greatly, causing noise increase depending on operation amount and inlet air temperature compared to where there is little difference in inlet air temperature and the distribution of the operation amount. Thus, in such a storage system including one or more drive units and one or more cooling fans, a first order of priority is set to a logical volume having the largest amount of power increase by the operation of the logical volume. A second order of priority is set to a drive chassis having the smallest power increase amount of the cooling fan. Reallocation is performed from the logical volume having the first order of priority to the drive chassis having the second order of priority.
