Abstract: Appropriate parameters can be efficiently set for network ports included in a storage apparatus. A storage apparatus 10 performing I/O processing on a storage drive 18 in response to an I/O request manages a first table 1700 in which a network device (SAS controller 151, SAS expander 191) is associated with location information of the network ports (network port 1514, network port 1914), a second table 1900 in which the cable length of a network cable 105 coupled to each of the network ports is associated with a port ID of the network port, and a relationship between the cable length of the network cable 105 and the parameter (output amplitude, pre-emphasis) set for the network port. The storage apparatus 10 acquires the cable length of the network cable 105 from the second table 1900, determines the parameters corresponding to the acquired cable length from the above relationship, and sets the determined parameter for the network port.

Abstract: According to the conventional art disk array system, when a drive box of a first chassis is blocked, all the drive boxes of a second chassis connected subsequently therefrom will be blocked, and the data in the drive boxes arranged subsequently therefrom cannot be recovered based on the RAID configuration. Even if the data could be recovered based on RAID configuration, it is necessary to perform the recovery process based on RAID in all the subsequently arranged drive boxes, according to which the performance is deteriorated. The present system stores a first drive box in a first chassis out of a plurality of chassis, and a second drive box and a third drive box are stored in a second chassis. One of a plurality of expander controllers within the first drive box is connected to an expander controller in the second drive box, and the other expander controller is connected to an expander controller in the third drive box.
