As cloud applications of server systems are more and more concerned and accepted by people, the demands of people on the storage capacity of servers are also expanding, and the simple resource scheduling and management method of the traditional data center cannot meet the increasing business demands. In order to meet increasing business requirements, a whole cabinet server is produced, the whole cabinet server integrates similar resources in various devices such as computing, storage, networks and the like into a resource pool in a hardware layer, and dynamic allocation of the resources is realized according to the business requirements through upper-layer software, so that various application requirements are met.
In order to realize the storage function, a JBOD (Just a Bunch Of Disks) storage node is added in the whole machine cabinet, an SAS data signal is received from a head server and expanded into multiple paths through Expander/SAS Switch, and a large number Of hard Disks are hooked to realize the expansion Of the storage capacity; in order to realize the calculation function, a calculation node is required to be added in the cabinet, PCIE signals of the CPU are led out through a PCIE slot or Slimuline connector, converted into SAS signals through an HBA card (optical fiber storage card) and then connected to a JBOD storage node through a Mini SAS HD connector and an external Cable (Cable), and the storage node Expander chip receives uplink high-speed SAS signals through 2-3 4i Mini SAS HD.
Due to the fact that a large number of MiniSAS HD (micro serial computer system interface board) and MiniSAS (micro serial computer system interface) cables are used, the phenomena of tray falling, speed reduction or bandwidth falling caused by poor cable connection occur, and maintenance personnel often need to start up a detection function after inserting and pulling cables one by one, so that whether the problem phenomenon is caused by the problem of cable connectivity is confirmed. The connection state of the JBOD and the handpiece server cable is usually after the cable is connected with a connector, and after the power-on is carried out with function detection, the connection condition of the cable is judged through whether the high-speed link is abnormal or not. When the phenomena of disk dropping, bandwidth dropping, speed reduction and the like occur, the cables need to be plugged and pulled one by one and the power-on detection function needs to be recovered to be normal. In the prior art, the connection state is detected in a hard disk function detection mode, and software is required to run each related function, so that the time consumption is long. When the function is abnormal, the cables need to be plugged and unplugged one by one and the function is verified again, which consumes labor and time and is easy to cause new connectivity problem caused by plugging and unplugging again.

The system comprises a computing node server and a JBOD storage node server; PCIE signals sent by a main board on a computing node server are converted into SAS signals through an HBA card located on the computing node server; the SAS signal is output to a plurality of second MiniSSAS-HD connectors on the JBOD storage node server expansion board through a plurality of first MiniSAS-HD connectors on the HBA card. After the expansion board is started, the SAS signal is expanded and then sent to a hard disk backboard on the JBOD storage node server; the first MiniSAS-HD connector is connected with the second MiniSAS-HD connector through a MiniSAS Cable.
The invention detects the connectivity of the connection between the compute node server and the JBOD storage node server through the JBOD expansion chip and displays the connection state of the cable at the JBOD front window.
FIG. 1 is a schematic diagram of a connection between a compute node server and a JBOD storage node server according to embodiment 1 of the present invention; the handpiece computing node server and the JBOD storage node server are interconnected through a MiniSAS Cable, and a plurality of MiniSAS-HD interconnection ports are respectively arranged on the handpiece computing node server and the JBOD storage node server; MiniSAS-HD not only transmits data signals, but also realizes mechanical connection, and the MiniSAS cable is in butt joint with the connector through a small gold finger plate inside the cable terminal.
In embodiment 1 of the present invention, 3 first MiniSAS-HD connectors are provided on the HBA card of the head computing node server, and 3 corresponding second MiniSAS-HD connectors are provided on the expansion board of the JBOD storage node server to communicate with the upstream first MiniSAS-HD connector.
Fig. 2 is a schematic diagram of a connection between the JBOD storage node server expansion board I2C and the first MiniSAS-HD connector on the upstream computing node server according to embodiment 1 of the present invention. The power supply of the expansion board includes P0V9_ AUX, P1V35_ AUX, and P1V8_ AUX.
The expansion board comprises an SAS expansion chip, a level conversion module and an I2C Switch chip. The expansion board supports multiple I2C. When the JBOD storage node server is in standby state, the SAS expansion chip converts any path of I2C signals into P3V3_ AUX through a level conversion module, converts the power supply voltage P1V8_ AUX of an expansion board into P3V3_ AUX, and then expands the signals into multiple communication signals through an I2C Switch chip to be respectively connected with a first MiniSAS-HD connector; and distinguishing MiniSAS Cable serial numbers according to different I2C Switch chip channels. The I2C Switch chip can expand one path of I2C into multiple paths, and I2C addresses on each expanded path do not conflict with each other.
The head computing node server and the JBOD storage node server are interconnected through a MiniSAS cable and transmit SAS signals and I2C signals. The head computing node server and the JBOD storage node server transmit SAS signals after being started, and the JBOD storage node server transmits I2C signals in a standby state.

A third storage module is arranged on the HBA card; the first MiniSAS-HD connector is also connected to a third storage module. The first memory module, the second memory module and the third memory module support more than three addresses, and it is assumed that the EEPROM addresses of the head, the head end cable terminal and the JBOD end cable terminal are 0XA4,0XA2 and 0XA0, respectively. The information stored in the first storage module, the second storage module and the third storage module is different. Because the SGPIO signal in the MiniSAS-HD cable is usually not used for interconnecting the head computing node server and the JBOD storage node server, the lighting of the JBOD storage node server hard disk is realized by issuing the SGPIO signal to the CPLD by the Expander, and the SGPIO signal of the head computing node server is not required to be connected. So the power supply of the third storage module on the head computing node server by the JBOD cable terminal can be realized by connecting I2C, P3V3_ AUX, GND with the SGPIO signal PIN in the cable. Three EEPROM power supplies and I2C pull-up levels on each link are provided by JBOD and are AUX power, and the EEPROM power supplies and the I2C signals are transmitted through idle SGPIO sideband signal links of the MiniSAS cable without occupying other PIN PINs.
