Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
According to an aspect of the present invention, an embodiment of the present invention provides a method for acquiring backplane information, as shown in fig. 1, which may include the steps of: s1, establishing connection with the BMC; s2, detecting the on-site level of each backboard corresponding to the BMC; s3, judging whether each backboard is in-place state or not according to the detection result; s4, acquiring the ID of the backboard in the in-place state; and S5, determining corresponding theoretical specification information according to the ID of the backboard in the on-position state.
The method disclosed by the invention determines the specification information of the backboard through the acquired backboard ID, is beneficial to maintaining the hard disk on the backboard, and can determine whether the backboard is in place or not through detecting the in-place level of the backboard.
In some embodiments, in the step S1, establishing the connection with the BMC, the method may further include: and acquiring the IP address of the BMC, and logging in a user interface of the BMC by using the user name and the password.
Specifically, a PC or a workstation in the local area network of the machine room can log in the corresponding BMC through an IP address and a username/password.
In some embodiments, determining whether each backplane is in the in-place state according to the detection result further includes:
in response to the on-position level being a low level, confirming that the backboard is in an on-position state;
and responding to the high level of the bit level, and confirming that the backboard is in a non-bit state.
In some embodiments, as shown in fig. 2, to be able to detect the presence level of the backplane, a 1PIN may be added to the I2C connector of the BMC of the backplane to indicate whether the backplane is present, where it is grounded. The working mechanism is that the GPIO of the BMC on the mainboard detects the PIN, the GPIO of the BMC on the mainboard is connected with a pull-up resistor, and when the GPIO of the BMC on the mainboard detects a low level, the backboard is detected to be in place. The BMC presents the information whether the backboard is in place in a BMC user interface, so that a user can manage the backboard in the server conveniently.
It should be noted that, only when the connection cable is connected to the backplane, the PIN is grounded, and at this time, the GPIO of the BMC on the motherboard detects a low level, and detects that the backplane is in place.
In some embodiments, when the presence of the backplane in place is detected, the ID of the backplane in the place state is acquired, and then the corresponding theoretical specification information is determined according to the ID of the backplane in the place state.
In some embodiments, determining the corresponding theoretical specification information according to the ID of the backplane in the in-place state further includes:
and determining the number, type and size of the hard disks supported by corresponding theory according to the ID of the backboard in the in-place state and a preset corresponding relation table.
Specifically, as shown in fig. 2, CPLD simulation PCA9555 and a backplane Board ID may be used, the BMC reads the PCA9555 simulated by CPLD through I2C to obtain a backplane Board ID, where the Board ID corresponds to the specification information of the backplane one by one, and the BMC determines the specification information of the backplane, such as how many hard disks are supported, the supported hard disk size, and the supported hard disk type (SAS SATA U.2 U.3), through the Board ID and a table of correspondence between the Board ID and the theoretical specification information, which is stored in advance.
It should be noted that the pre-stored association table between the Board ID and the theoretical specification information may be stored in the BMC or in another cache.
In some embodiments, while acquiring the backplane ID, a level combination of PIN PINs of the hard disk connector on the backplane in the on-site state may also be acquired, and then actual hard disk type information connected to the hard disk connector is determined according to the level combination.
Specifically, as shown in fig. 2, the CPLD on the backplane is used to confirm that the type of the hard disk on the current backplane is SAS/SATA or U.2 or U.3 by detecting the high/low levels on P4, P10 and E6 on the hard disk connector, and notifies the BMC through I2C.
In some embodiments, the correspondence between the hard disk type and the signals on P4, P10, E6 may be: when PRSNT # (P10) is GND, IfDet # (P4) is GND, IfDet2# (E6) is HIGH, the hard disk type may be SAS/SATA, when PRSNT # (P10) is HIGH, IfDet # (P4) is GND, IfDet2# (E6) is HIGH, the hard disk type may be U.2, when PRSNT # (P10) is HIGH, IfDet # (P4) is GND, IfDet2# (E6) is GND, the hard disk type may be U.3.
In some embodiments, the method further comprises:
and presenting the theoretical specification information and the actual hard disk type information on a user interface of the BMC.
Specifically, after determining the theoretical specification information corresponding to the backplane and the actually connected hard disk type information, the BMC may return to the user interface and display the theoretical specification information and the actually connected hard disk type information on the user interface.
By the method provided by the invention, the problem that the specification information of the backboard, such as how many hard disks are supported, the supported hard disk size and the supported hard disk type (SAS SATAU.2 U.3) cannot be identified by the conventional scheme, is solved without increasing the additional hardware cost, and the specification information is displayed to a user at a BMC user side in a graphical interface mode, so that the use is convenient. Meanwhile, the problem that the information of whether the back plate is in place cannot be presented to a user by the existing scheme can be effectively solved by a method for detecting the in-place level.
