Abstract:
1. A computer system configured of a plurality of computers, a plurality of storage subsystems, and a storage management computer, comprising: said computers having means for transmitting a plurality of input/output requests and input/output data between said computers and a first portion of said storage subsystems through Ethernet and between said computers and a second portion of said storage subsystems through a Fibre Channel (FC), said first portion of said storage subsystems including at least one Internet SCSI (iSCSI) storage device; said storage subsystems including at least one of first storage device to be accessed by said computers according to a file access protocol and at least one of second storage device to be accessed by said computers according to a block access protocol, said second storage devices including said iSCSI storage device; said storage management computer connected with said storage subsystems through said Ethernet and FC and having, a display apparatus, and a physical view display means for displaying physical connecting relation on said display apparatus in one of (a) a first display mode of displaying said computers and said storage subsystems interconnected through said Ethernet and their connecting relation (topology), (b) a second display mode of displaying said computers and said storage subsystems interconnected through said FC and their connecting relation (topology), and (c) a third mode of displaying the physical connecting relation both of said first and second display modes at a time, a logical view display means for displaying logical connecting relation on said display apparatus in one of (d) a fourth display mode for displaying said computers, said first storage devices and their topology, said first storage devices being identified under a first condition that a export directory of each of said storage device is specified as a mount point, and (e) a fifth display mode for displaying said computers, said second storage devices and their topology, said second storage devices being identified under a second condition that said block access protocol is used to access to each of said devices and/or a third condition that said export directory of each of said storage devices is not specified, (f) a sixth mode of displaying the logical connecting relation both of said third and fourth display modes at a time, (g) a seventh display mode for displaying unused storage device, and (h) an eighth display mode for displaying connection between said computers and said first and second storage devices under access limitation, and means for allowing a user to select one of said first to eighth display mode.
