A non-transitory computer readable storage medium that stores a storage control program causing a computer to execute a control process of a storage including a first storage device with first access speed, and a second storage device with second access speed that is slower than the first access speed, includes monitoring access frequency to data in the first and second storage devices; relocating data, the access frequency of which exceeds a first reference value, in the second storage device, to the first storage device; and conducting a overload processing of retaining, in the cache memory, at least a part of the data in the second storage device when the second storage device is in an overload state. the access frequency monitoring is executed in a state where the partial data is retained in the cache memory, and the relocating is executed based on the access frequency to the partial data.

Storage control program for hierarchy relocation control, storage system with hierarchy relocation control and hierarchy control apparatus thereof

Device component information (physical information, logical information) on each device such as a host computer, a switch, and storage on the SAN is acquired via an LAN. Element information is created from the acquired device component information. According to the element information, a link between element information is created. Furthermore, when a plurality of links are established for an element, information is stored in advance so as to be used for selecting one of the links. Thus, each element stored the minimum information for routing and it becomes possible to search an associated element more effectively.

Storage medium storing relation management control program, device, and system

When a server RM detects a failure in an operating server, a system resource manager selects a substitute server from a pool of a server domain to which a failed server belongs, based on information in a system resource DB, disconnects the failed server from a business network and a storage sub group and moves the failed server to a pool, and permits the substitute server to access a storage group to which the failed server had an access and to connect to the business network to which the failed server was connected, to boot up the substitute server from a SAN.

Switching connection of a boot disk to a substitute server and moving the failed server to a server domain pool

When information on a device such as a server, storage, and an FC switch constituting a SNA system is input, these devices are displayed and arranged properly on a screen (S, S). When information on a physical path is input by a designer by using this display screen, a virtual SAN system in which the devices are connected by a fiber channel is displayed on the screen (S). Furthermore, when information on an access path is input by the designer by using the construction image, the access path is additionally displayed on the construction image of the virtual SAN system (S). Since the construction image of the virtual SAN system is displayed on the screen, the designer can easily create a design drawing while visually checking the SAN system. This can reduce the work load and time required for construction of the SAN system.

Apparatus for aiding construction of storage area network system and method therefor

On the screen of a computer, a server, a storage device and an FC switch are virtually provided and these devices are connected by a physical path. When an instance is generated in the server and the instance is dragged/dropped into the storage device, both the command to establish a multipath and the command to acquire a data area corresponding to the instance in the storage device are automatically generated. These commands are transmitted to the respective devices of an actually configured storage system.
