摘要:
A data storage system connectable to a host unit which issues data read/write requests to the data storage system, and which includes a plurality of disc units, and a controller connected to the disc units. A fault can occur in any of the disc units. The disc units store data in a plurality of data groups and error correcting data corresponding to each of the data groups. The controller, operable in different modes, performs processing of reconstructing data stored in any of the disc units in which a fault has occurred based on all other data belonging to any of the data groups to which the data to be reconstructed belongs and error correcting data corresponding to any of the data groups to which the data to be reconstructed belongs, and performs processing of data read/write requests from the host unit.

A storage system capable of restoring data even if packets have been lost in exchanges of the data between storage apparatus each conforming to an iSCSI protocol adopting an FEC technique. In a storage system comprising storage apparatus each conforming to an iSCSI protocol adopting an FEC technique, each of the storage apparatus is provided with an FEC function and, when data is transmitted from an iSCSI layer to another iSCSI layer, the state of an FEC process and a redundancy of the data transmission are changed to values suitable for a transmission destination prior to the transmission so that the data can be restored at the destination of transmission.

To provide an electrically driven power steering apparatus with a simple structure, which can prevent overloading of an electrical motor and a power transmission system, an absorbing member (121) is attached to a rack shaft (112), and is brought into contact with a rack housing face at a stroke end of the rack shaft (112). The absorbing member (121) at least partially has a material having a Young's modulus of 100 to 900 Mpa, and thus it is possible to effectively relieve an impact at the stroke end.

An image synthesizing device includes a graphics data expanding unit 2 for securing a rectangular area 4a whose alpha value is “0” in a region of a non-display memory 4, the region corresponding to a display area in which moving image data is to be displayed, and for expanding motionless graphics data onto a region of the non-display memory 4, the region corresponding to a display area in which the motionless graphics data is to be displayed, and a moving image data expanding unit 3 for expanding the moving image data onto a non-display memory 5. The image synthesizing device then synthesizes the graphics data which are expanded onto the non-display memory 4 and the graphics data which are expanded onto the non-display memory 5.

In an electrophotographic endless belt having a resin layer formed of a resin composition containing a polyamide, the resin composition further contains a copolymer obtained by copolymerization of an olefin and an oxygen-containing heterocyclic compound, a curve (T-log10 η curve) showing the relationship between temperature T (° C.) and common logarithm log10 η of melt viscosity η (Pa·s), of the resin composition has, in the range of log10 η of from log10 1,000 to log10 8,000, a gently inclined region the inclination Δ log10 η/ΔT of which is from −0.02 to 0, and the gently inclined region has a temperature range of 10° C. or more, and the resin layer has a thickness the maximum thickness of which is 115% or less of the average value of the thickness of the resin layer and the minimum thickness of which is 85% or more of the average value of the thickness of the resin layer. Also disclosed is a process for producing the above electrophotographic endless belt.
摘要:
In a storage system directly connected to a network, if conventional interfaces and protocols are used when an I/O command issued from a file server is transmitted to the storage system, the command/data is serially transferred via a single transfer path so that the performance is lowered. Conventional interfaces do not provide the means to notify the storage system of the failure at the file server. The file server and a channel adapter of the storage system are mounted on the same board and connection paths therebetween are controlled so that a plurality of protocols can be operated independently. A path independent from a command/data path is provided between the file server and channel adapter, and the received failure information is stored in a shared memory of the storage system and used for the fail-over.
