Information system
First Claim
1. An information system, comprising:
- a server;
a data storage device, accessed by said server by issuing an input/output request in order to write information or to read said written information; and
a connection device connected to said server and to said data storage device, including a transmission/reception unit to mediate information exchanged between said server and said data storage device, which transfers said input/output request transmitted from said server to said data storage device, and transfers information transmitted by said data storage device in response to said input/output request to said server, wherein said connection device further includes;
a memory unit for storing in advance a test list which associates information identifying said data storage device to be tested with setting information related to tests; and
an input/output analysis unit, connected to said transmission/reception unit and to said memory unit, which, upon input of said input/output request received by said transmission/reception unit, references said test list and judges whether the destination of the input/output request is said data storage device to be tested, and if the destination of the input/output request is said storage device to be tested, outputs the input/output request to said transmission/reception unit after a prescribed length of time has elapsed.

Abstract
An information system is provided including a server, a data storage device and a connection device; and is characterized in that the connection device includes a memory unit for storing a test list in which are associated information identifying the data storage device to be tested and setting information relating to tests; and a test unit which upon input of the input/output request, references the test list and judges whether the destination of the input/output request is the data storage device to be tested, and if the destination of the input/output request is the storage device to be tested, outputs the input/output request to the transmission/reception unit after a prescribed length of time.

3. An information system, comprising:
-
a server;
a data storage device, accessed by said server by issuing an input/output request in order to write information or to read said written information; and
a connection device connected to said server and to said data storage device, including a transmission/reception unit to mediate information exchanged between said server and said data storage device, which transfers said input/output request transmitted from said server to said data storage device, and transfers information transmitted by said data storage device in response to said input/output requests to said server, wherein said connection device further includes;
a memory unit for storing in advance a test list which associates information identifying said data storage device to be tested with setting information related to tests; and
an input/output analysis unit, connected to said transmission/reception unit and to said memory unit, which, upon input of said input/output request received by said transmission/reception unit, references said test list and judges whether the destination of the input/output request is said data storage device to be tested, and if the destination of the input/output request is said storage device to be tested, generates an error message at a prescribed rate and outputs the error message to said transmission/reception unit, and wherein said transmission/reception unit, upon input of said error message from said input/output analysis unit, sends said error message to said server which had issued said input/output request. - View Dependent Claims (6)

4. An information system, comprising:
-
a server;
a data storage device, accessed by said server by issuing an input/output request in order to write information or to read said written information; and
a connection device connected to said server and to said data storage device, including a transmission/reception unit to mediate information exchanged between said server and said data storage device, which transfers said input/output request transmitted from said server to said data storage device, and transfers information transmitted by said data storage device in response to said input/output request to said server, wherein said connection device further includes an input/output generation unit, connected to said transmission/reception unit, which generates an input/output request with said connection device as request source and said data storage device as destination, and outputs the generated input/output request to said transmission/reception unit, and wherein said transmission/reception unit, upon receiving information from said data storage device in response to said input/output request generated by said input/output generation unit, discards the information.

7. A testing method for use in an information system having:
-
a server;
a data storage device, accessed by said server by issuing an input/output request in order to write information or to read said written information; and
a connection device connected to said server and to said data storage device, including a transmission/reception unit to mediate information exchanged between said server and said data storage device, which transfers said input/output request transmitted from said server to said data storage device, and transfers information transmitted by said data storage device in response to said input/output request to said server, said testing method being a testing method of generating a pseudo-load on said data storage device comprising the steps of;
receiving an input/output request issued by said server to said data storage device at said connection device;
judging whether the destination of the input/output request is said data storage device to be tested at said connection device; and
if the destination of the input/output request is the storage device to be tested, holding the input/output request for a prescribed time before transmitting to said data storage device of said destination at said connection device. - View Dependent Claims (10)

8. A testing method for use in an information system having:
-
a server;
a data storage device, accessed by said server by issuing an input/output request in order to write information or to read said written information; and
a connection device connected to said server and to said data storage device, including a transmission/reception unit to mediate information exchanged between said server and said data storage device, which transfers said input/output request transmitted from said server to said data storage device, and transfers information transmitted by said data storage device in response to said input/output requests to said server, said testing method being a testing method of generating an error for said data storage device comprising the steps of;
receiving an input/output request issued by said server to said data storage device at said connection device;
judging whether the destination of the input/output request is said data storage device to be tested at said connection device; and
if the destination of the input/output request is the storage device to be tested, transmitting an error message at a prescribed rate to said server issuing the input/output request at said connection device. - View Dependent Claims (11)
