摘要:
A management device selects a storage device having a plenty of unallocated storage regions, selects a target using a port having a small allocation quantity from the storage device targets, and allocates the target, an initiator, and a storage region. When the number of targets and the allocated storage regions prepared by the storage device is within a predetermined number, the storage device manages the storage device as an allocation candidate. When the predetermined number is exceeded, the exceeding one is excluded from the allocation candidate. When the number of storage devices excluded from the allocation candidate has reached a certain number, the management device manages a new storage device and a new storage region as an allocation candidate.

In an environment where there is a possibility that the user connects from a plurality of blade PCs to the storage, the present invention prevents the data destruction by realizing the exclusive control of the storage device. The storage connection from a blade PC which was possible to connect until now is made to be impossible by that the management server newly generates and sets to the storage device the connection information between the storage device which the blade PC keeps. Further, by sending the newly generated connection information to the other blade PC the connection from that blade PC becomes possible.

Even if each processor core uses the same logical address, a processing-target program corresponding to each processor core can be selected. A logical address of multiple address mapping tables is set to a same logical address in correspondence with an embedded OS program or a RAID management program, and a physical address is set to a different physical address in correspondence with the actual storage destination of an embedded OS program or a RAID management program. Each processor core, on start-up, uses a self address mapping table to execute address mapping processing with each processor core based on the same logical address, selects an embedded OS program or a RAID management program according to the physical address obtained in the address mapping processing, and executes processing according to the selected program.
摘要:
In the present invention, the scope and degree of the effect of hardware alterations on software is grasped, and development is performed while making coordination between software and hardware. The storage system comprises a plurality of hardware elements and a plurality of software elements, and these respective elements are connected via a plurality of interface elements. The development support system respectively acquires and analyzes specification information relating to the hardware elements and software elements comprising the storage system, and produces software effect information that indicates the effect on the software. The development sections promote cooperative development while referring to the software effect information.

A storage system including a plurality of logical units; file management application software for performing file management on a per-file basis for a plurality of files stored in the respective logical units; a load monitoring module for monitoring a load in a resource of the storage system; and a file management control module for controlling the file management application software based on the load monitored by the load monitoring module.
摘要:
A storage controller of the present invention can specify an updated file based on an updated block detected when a differential backup is carried out for a plurality of generations, and can carry out a virus scan for the updated file only. Difference data generated between a primary volume and a backup volume is managed in difference volumes of different generations. A file updated by the host is specified based on an updated block in which the difference data is stored. A virus scan, which makes use of the latest virus pattern file, is executed for this updated file. Furthermore, search information related to the updated file can be created, and this search information can also be saved.

摘要:
The present invention enables program codes to be shared among processors 211. To prevent the debug operation of one processor 211 from affecting the debug operation of the other processors 211, when detecting a breakpoint during execution of a program code, a debugger 410 or a debugger stub 520 controls the execution of the program code while exchanging breakpoint information 800 with the other debuggers 410 or the other debugger stubs 520. Furthermore, a circuit 170 is created which prevents the program code being carelessly rewritten due to thermal runaway, a bug, and the like of a processor 211, and the protection setting by the protection logic 71 in the circuit 170 is released only in case the processor 211 accesses each of a plurality of registers from 65 to 67 in specified order.
