Abstract
The utility model discloses a device for testing integrity of a hard disc card signal based on the SAS data bus, and belongs to the device for testing the signal integrity. The structure of the devicecomprises a hard disc card and a testing device. The hard disc is connected with the testing device through a core adapter board which is provided with a Mini SAS interface, an SATA interface and a bus channel for connecting two interfaces. The Mini SAS interface of the hard disc card is connected with the Mini SAS interface of the core adapter board. The SATA interface of the core adapter boardis connected with the testing device. Compared with the prior art, the device for testing integrity of a hard disc card signal based on the SAS data bus according to the utility model uses the normaldevice and method for testing the integrity of SATA signal transmission for testing instead of a special testing device. The testing time is shortened and the correctness of the testing result is ensured.
Description
Technical field
The utility model relates to a kind of device of test signal integrality, and specifically a kind of test is based on the device of the hard disk card signal integrity of SAS data bus.
Background technology
At present, the test of SATA signal transmission integrity is a kind of proving installation of maturation, and corresponding testing apparatus is arranged.Hard disk card based on the SAS data bus is nearest new product, does not have direct proving installation and equipment to go to verify its integrality for the signal by the output of SAS interface.
The interfacing of SAS can backward compatible SATA.Specifically, the compatibility of the two is mainly reflected in the compatibility of Physical layer and protocol layer.In Physical layer, SAS interface and SATA interface are compatible fully; At protocol layer, SAS is made up of 3 types of agreements, uses corresponding protocol to carry out data transmission according to the distinct device that connects.Wherein SATA channel protocol (STP) is used for the transmission of data between SAS and the SATA.Therefore under the cooperation of this agreement, SAS can with SATA equipment seamless combination.
The utility model content
Technical assignment of the present utility model is at above weak point, and the device of a kind of a kind of test simple in structure, easy to use based on the hard disk card signal integrity of SAS data bus is provided.
The technical scheme that its technical matters that solves the utility model adopts is: comprise hard disk card, proving installation, hard disk card is connected by the core card extender with proving installation, the core card extender is provided with Mini SAS interface, SATA interface and the bus run that is connected two interfaces, the Mini SAS interface of the Mini SAS interface of hard disk card and core card extender joins, and the SATA interface and the proving installation of core card extender join.
Proving installation is the proving installation of SATA signal transmission integrity.
Based on the compatibility of SATA and SAS interfacing, the SAS signal is input to the result that just can obtain signal integrity in the testing apparatus by the SATA data bus.
During use, the SAS signal that hard disk card sends enters testing apparatus through the core card extender by data bus lane.
The test of signal integrity is to be the basis for estimation of standard with the eye pattern.Make waveform of hard disk card output, testing apparatus can receive this waveform and produce one group of eye pattern.When the eye pattern line of the blueness that produces does not contact generation with the red rhombus that is in central authorities, can judge that this signal is complete.
A kind of test of the present utility model is compared with prior art based on the device of the hard disk card signal integrity of SAS data bus, compatibility based on SATA and SAS interfacing, use the testing apparatus and the method for testing of original SATA signal transmission integrity to test, rather than must use special test equipment to test, shorten the test duration, guaranteed the correctness of test result; Thereby, have good value for applications.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is that structure of the present utility model connects block diagram.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of test of the present utility model is based on the device of the hard disk card signal integrity of SAS data bus, its structure comprises hard disk card, proving installation, hard disk card is connected by the core card extender with proving installation, the core card extender is provided with Mini SAS interface, SATA interface and the bus run that is connected two interfaces, the Mini SAS interface of the Mini SAS interface of hard disk card and core card extender joins, and the SATA interface and the proving installation of core card extender join.
Proving installation is the proving installation of SATA signal transmission integrity.
The SAS signal that sends based on the hard disk card of SAS data bus enters into by the core card extender on the proving installation of SATA signal transmission integrity, finally draws the test result of integrality.
A kind of test of the present utility model is very simple and convenient based on its processing and fabricating of device of the hard disk card signal integrity of SAS data bus, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
Claims (2)
