Abstract: Provided is a computer system including a host computer, a plurality of virtual storage systems coupled to the host computer, a storage system coupled to the plurality of virtual storage systems, and a management computer. The storage system includes storage areas provided as volumes to the host computer. Each of the virtual storage systems provides virtual volumes corresponding to the volumes to the host computer. The host computer disperses a plurality of data I/Os containing data to be written in one of the volumes to the virtual volumes of a plurality of paths reaching the one of the volumes at a determined ratio. The management computer calculates a threshold value of a performance value to be set in the virtual volume of each of the paths to determine whether to generate an alert based on the predetermined ratio. Thus, performance of the computer system is properly managed.

Abstract: A frame forwarding apparatus connected between an ISP router and a plurality of subscriber terminals comprises a frame forwarding processing unit and a VLAN bundling table defining the correspondence of subscriber side line information with ISP router side line information and subscriber terminal's MAC address. The subscriber side line information includes a physical line number and a subscriber VLAN identifier, and the ISP router side line information includes a physical line number connected to the ISP router and a group VLAN identifier. By referring to the VLAN bundling table, the frame forwarding processing unit operates to convert a VLAN identifier given in a frame received from a subscriber terminal into a group VLAN identifier and to convert a VLAN identifier given in a frame received from the ISP router into a subscriber VLAN identifier, before forwarding the frame to its destination.

Abstract: The present invention provides a wire/pipe support device of a motorcycle that can possess a sufficient space for accommodating a wire/pipe without increasing the degree of forming of a vehicle body frame. A wire/pipe support device includes a groove-shaped engaging portion that is engaged with a main frame that constitutes a vehicle body frame of a motorcycle and has a lower surface thereof opened. A groove-shaped accommodating portion receives the wire/pipe thereon and has an upper surface thereof opened. The engaging portion is mounted on the vehicle body frame by engaging the engaging portion with the vehicle body frame from above. The wire/pipe is placed on the accommodating portion. The wire/pipe support device is pushed from above by a fuel tank directly or by way of a cushion member thus preventing the floating of the wire/pipe support device from the vehicle body frame and the rotation of the wire/pipe support device about the vehicle body frame.

Abstract: Upon receiving a connection request from a terminal, a packet transfer apparatus registers information on the terminal with a memory and forwards information necessary for the authentication of the terminal and an authentication request to an authentication server. The apparatus then receives authentication permission and a multicast group address list associated with the terminal that has made the connection request from the server. The apparatus then associates the multicast group address list received with the terminal information stored in the memory for registration. Upon receiving a participation request from the terminal, the apparatus determines whether or not the group address contained in the participation request is present in the list in the memory. If the group address is present in the list in the memory, the apparatus permits the delivery of a packet to the terminal from a content delivery server and transmits the packet to the terminal.

Abstract: A packet transfer apparatus for accommodating a plurality of hosts to transfer packets between the plurality of hosts and an ISP network. Upon receipt of a connection authentication request from a host, the packet transfer apparatus transmits ID and password information (information required for authentication) included in the request to an authentication server in the ISP network, acquires IP address information for the host from the authentication server, and notifies a DNS server in the ISP network of the IP address information, and previously registered domain name information of the host.

Abstract: A steering device for a personal watercraft includes a handle holder fitted to a watercraft body. A steering shaft passes through the handle holder, and a handle is fitted to the upper end of the steering shaft. The steering shaft is provided with a groove, and a holding member is provided in the handle holder and is fitted into the groove. Accordingly, movement of the steering shaft in the axial direction is restricted. A flange or the groove has a shape such that its width can be reduced. When the holding member is fitted by setting the width to a small size, and taking dimensional variations into account, the chattering between the flange or the groove and the holding member can be reduced. In view of this, the steering shaft is provided with the flange or the groove, and the holding member provided in the handle holder is fitted to the flange or the groove, so that movement of the steering shaft in the axial direction can be restrained.

The upper intake section and the lower intake section are partitioned by a mesh member. An air cleaner element is arranged in an extension section of the lower intake section, so that, after external air flows into the lower intake section via the air cleaner element, the air flows to the upper intake section, and then into the intake ports.

Abstract: A packet transfer apparatus which can switch a communication path for each of a plurality of users using the same L2TP tunnel is provided. Packet transfer apparatuses terminating L2TP contain a table specifying a flow threshold level and a priority level of each subscriber; the amount of packet flow of each subscriber is measured in accordance with the information in the table; if the threshold level is exceeded, the packet communication path is switched in accordance with the priority level specified for each subscriber. The OSPF protocol is used to manage the path information, and the information of a plurality of paths to a destination is stored in a path management table. The path is switched by specifying destination routers with the source routing option in the IP header of a packet after L2TP encapsulation.

Abstract: A personal watercraft includes an inner lid attached in covering relation over a rear portion opening provided in a deck of the personal watercraft, in which a rear edge of the rear portion opening is pressed by a locking member disposed in a locking position thereof to assure the air-tightness of the inner lid, and a rear cover 48 is provided in covering relation over the inner lid. A projection is provided integrally on the locking member which allows attachment of the rear cover when the locking member is in the locked position, but blocks attachment of the rear cover by being sandwiched between the deck and the rear cover, when the locking member is at an unlocked position thereof. A torsion spring (biasing member) which biases the locking member toward the unlocked position is provided between the locking member and the deck. The attaching structure prevents the inner lid from being not attached inadvertently.
