International Classification:

G06F 11/00
G06F 7/02
G01R 31/28
H03M 13/00

US Classification:

714 55, 714 49, 714 51, 714712, 714815, 714821

Abstract:

A method and apparatus for testing a data transfer system. The method comprises the steps of storing a first table, the first table noting at least a time of issuance of at least one command and a time of completion of the command and comparing the time of issuance of the command and the time of completion of the command. A timeout condition is registered if the processor determines that a time longer than a predetermined time elapsed between the time of issuance of the command and the time of completion of the command.

International Classification:

G06F 13/38

US Classification:

710 29, 710 33, 710 54, 710 72

Abstract:

Apparatus and associated systems and methods may relate to a data traffic modification system that may include a processing module to handle SATA-compliant data transfers in which a source device or a target device issues requests to pause and subsequently to resume the data transfer. In various implementations, a data traffic modification device may selectively modify data traffic upon the occurrence of a predetermined condition. In one illustrative example, if a target device for the data transfer issues a pause request (e. g. , to prevent a buffer overflow), the data traffic modification device may generate a pause acknowledge signal to the target device within a response time specified by the protocol. In another illustrative example, if a source device for the data transfer issues a pause request, the data traffic modification device may generate a pause acknowledge signal to the source device within the response time specified by the protocol.

US Classification:

711118, 711154

Abstract:

Apparatus and associated systems and methods may relate to a data traffic modification system that may modify a data stream as a function of a selected data value in the data stream, where the data value is selected from among values received into a buffer before the occurrence of a trigger condition. In an illustrative example, a buffer in a data traffic modification device may receive and temporarily store multiple data values being transferred between a source device (e.g., server) and a target device (e.g., storage area network). In some embodiments, the buffered data may contain data to be captured in response to detecting a trigger condition. The captured data, for example, may be used to generate a substitution value for another location in the data stream. Accordingly, some implementations may provide for capture of data values that precede a trigger data value within a data stream.
