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.

In an embodiment, referring to fig. 1 and fig. 2, the present invention provides an apparatus for adjusting a disk sequence of a hard disk, specifically, the apparatus includes:

specifically, a RAID card is a board card for implementing a RAID function, and is generally composed of a series of components such as an I/O processor, a SCSI controller, a SCSI connector, and a temporary storage. Different RAID cards support different RAID functions. The first function of the RAID card is to allow a plurality of disk drives to transmit data simultaneously, and these disk drives are logically one disk drive, so that the rate of a single disk drive can be several times, several tens of times, or even hundreds of times by using RAID. The second important function is that it can provide fault tolerance. The third and most important function is to ensure data security. The hard disk serial number is the hard disk sequence displayed by the hard disk under the BIOS setup menu (or OS), so that the user can easily know the information such as the hard disk position, the hard disk model, the hard disk capacity and the like corresponding to the hard disk slot at a glance, and the user can conveniently group the RAID function through the hard disk serial number. For example, assume that there are 8 hard disks, and the hard disk serial numbers corresponding to the eight hard disks may behard disk 0, hard disk 1,hard disk 2, hard disk 3, hard disk 4, hard disk 5, hard disk 6, and hard disk 7.

The system comprises a plurality of hard disk slot positions, a plurality of data processing units and a plurality of data processing units, wherein the hard disk slot positions are configured for inserting hard disks, each hard disk slot position corresponds to a slot position serial number on a back plate, and the number of the hard disk slot positions is the same as that of physical ports of the RAID card; the slot number refers to an arrangement serial number of the slot on the hard disk backplane, for example, it is assumed that a certain server backplane includes 8 slots (slots), and usually the 8 slots are sequentially marked asslot 0, slot 1,slot 2, slot 3, slot 4, slot 5, slot 6, and slot 7.

and the control assembly is configured to read the board card information of the RAID card, determine the hard disk serial number corresponding to each physical port of the RAID card according to the board card information, and adjust the mapping relation between the input pin and the output pin of the Expander card based on the hard disk serial number corresponding to each physical port, so that each pair of mutually communicated hard disk slot positions and slot position serial numbers corresponding to the physical ports are the same as the hard disk serial numbers. The slot serial number is the same as the hard disk serial number, which means that thehard disk 0 corresponds to theslot 0, the slot 1 corresponds to the slot 1 … …, and so on, that is, the slot serial number should be understood as corresponding in a broad sense.

In yet another embodiment, referring again to fig. 1 and 2, the control components include a Baseboard Management Controller (BMC) and an integrated south bridge (PCH), which is a series of chipsets introduced by intel in 2008);

In yet another embodiment, the device further comprises a display;

the display is connected with the substrate management controller;

In yet another embodiment, the baseboard management controller and the integrated south bridge are connected by an LPC bus or an SPI bus.

In yet another embodiment, the device further comprises a CPLD and an indicator light;

In another embodiment, the Active LED signal, the Locate LED signal, and the Fault LED signal of each hard disk are respectively connected to three GPIO pins of the CPLD, and the indicator lamps include three indicator lamps corresponding to the Active LED signal, the Locate LED signal, and the Fault LED signal. By way of specific example, the indicator lights may include green, red, yellow; certainly, in order to facilitate the discovery of users under the condition of faults, one of the indicator lamps can be replaced by a buzzer, and the buzzer can automatically give an alarm when the Fault LED signal is generated by the hard disk.

In yet another embodiment, the hard disk is a mechanical hard disk or a solid state hard disk.

In another embodiment, to facilitate understanding of the technical solution of the present invention, two RAID cards are taken as an example for detailed description, wherein the a RAID card (for short, a type card) and the B RAID card (for short, B type card) are provided by two different manufacturers, each of the a type card and the B type card has 8 physical ports denoted as phy0, phy1, and … … phy7, and the serial numbers of the hard disks corresponding to the 8 physical ports in the system are 0, 2, and … … 7, and the difference between the a type card and the B type card is: the hard disk serial numbers corresponding to the physical ports of the type a cards are sorted in a positive order (i.e., from 0 to 7), while the hard disk serial numbers corresponding to the physical ports of the type B cards are sorted in a reverse order (i.e., from 7 to 0), and the specific configuration modes of the device of the present invention for the type a cards and the type B cards are as follows:

the first scenario assumes that the server is collocated with a type a RAID card:

referring to fig. 1, when the system is powered on and powered on, the BMC may actively read the manufacturer information (vendor ID, device ID) on the RAID card through the I2C interface, then the PCH reads the RAID card information read by the BMC through the LPC (or SPI) interface, and then the PCH obtains the hard disk serial number corresponding to the physical port of the RAID card by comparing the information of the manufacturer RAID card a through the internal BIOS estimation. It should be noted that the BIOS firmware inside the PCH needs to write information of the corresponding relationship of the physical port of each RAID card supported by the server in advance, so that the input/output mapping relationship of the Expander card can be dynamically changed into a correct disk order that matches the hard disk slot order on the hard disk backplane of the server by changing the temporary memory of the internal firmware.

The corresponding relation between a physical port defined by the internal firmware of the type A card and a physical input pin of an Expander card of the server is assumed to be shown in table 1;

TABLE 1 correspondence between physical ports of type A cards and input pins of Expander cards

RAID card physical port	Expander cardinput pin
		Phy
0	Phy0
		Phy1	Phy1
Phy2	Phy2
		Phy3	Phy3
Phy4	Phy4
		Phy5	Phy5
Phy6	Phy6
		Phy7	Phy7

Assume that the mapping relationship between the input pins and the output pins of the initial settings estimated inside the Expander card of the server is shown in table 2;

TABLE 2 Expander card input pin and output pin mapping relationship

Expander card input pin	Expander cardoutput pin
		Phy
0	Phy8
		Phy 1	Phy9
Phy
	2	Phy 10
Phy 3			Phy 11
	Phy 4	Phy 12
Phy 5			Phy 13
	Phy 6	Phy 14
Phy 7			Phy 15

At this time, the corresponding relationship between the output pin port initially set in the inside firmware of the Expander card of the server and the slot position serial number of the hard disk board is shown in table 3;

TABLE 3 Expander card output pin and slot number correspondence on backplane

Expander output pin	Number of slot on back board
		Phy 8	Slot 1
Phy 9	Slot 2
		Phy 10	Slot 3
Phy 11	Slot 4
		Phy 12	Slot 5
Phy 13	Slot 6
		Phy 14	Slot 7
Phy 15	Slot 8

Therefore, it can be seen that the correspondence between the physical port of the type a card and the serial number of the slot of the hard disk backplane on the server is shown in table 4:

TABLE 4A type card physical port and backboard slot number correspondence

Because the sequence correspondence relationship between the physical port defined by the internal firmware of the type a RAID card of the above example and the hard disk slot on the hard disk backplane designed by the server is consistent, the BIOS firmware determines that the physical output pin sequence initially set by the internal firmware of the Expander card does not need to be dynamically changed, and the PCH also transmits the correct hard disk sequence to a display (monitor) through a VGA interface of the BMC in an image information manner, so that the correct disk sequence corresponding to the hard disk of the RAID card and the hard disk of the server backplane can be displayed under the BIOS setting menu (or OS).

The second scenario assumes that the server is collocated with a type B RAID card:

referring to FIG. 2, the physical port defined by the internal solidification of the pseudo-type B RAID card corresponds to the input pin of the Expander card of the server as follows

TABLE 5 correspondence between physical ports of type B cards and input pins of Expander cards

RAID card physical port	Expander card input pin
		Phy 7	Phy0
Phy 6	Phy1
		Phy 5	Phy2
Phy 4	Phy3
		Phy 3	Phy4
Phy
	2	Phy5
Phy 1			Phy6
	Phy
0		Phy7

The correspondence between the input pins and the output pins of the initial setting estimated in the Expander card of the server is assumed to be shown in table 2; at this time, the corresponding relationship between the physical port of the type B RAID card and the slot position of the hard disk backplane on the server is shown in table 6;

TABLE 6 correspondence between physical ports of type B cards and slot numbers of backplane

From table 6, the disk order corresponding to the hard disk backplane on the server is out of order because the physical port defined by the internal firmware of the type B RAID card corresponds to the physical output pin through the initial setting of the internal firmware of the Expander card.

According to the technology, the BMC can actively read factory information (supplier ID and equipment ID) on the RAID card through the I2C interface, then the PCH reads the RAID card information read by the BMC through the LPC (or SPI) interface, and then the PCH compares the information of the RAID card of the B factory through the internal BIOS firmware to obtain the corresponding hard disk serial number of the physical port of the RAID card in the system.

Then the PCH dynamically changes the sequence of the physical output pins into a correct disk sequence conforming to the sequence of the hard disk slots of the hard disk backplane of the server by dynamically changing the register through the firmware inside the Expander card via the I2C interface, and the mapping relationship between the physical input pins and the output pins of the dynamically changed firmware inside the Expander card is shown in table 7 below;

furthermore, after the firmware inside the Expander card modifies the corresponding relationship between the physical port of the type B RAID card and the slot number of the backplane on the server, the slot number is adjusted as shown in table 8, and the correct disk order corresponding to the hard disk of the RAID card and the hard disk of the server backplane can be displayed under the BIOS setting menu (or OS).

Table 7 mapping relationship between input pins and output pins of Expander card after adjustment

TABLE 8 corresponding relationship between physical ports of type B cards and slot numbers of backplane

By combining the listed disk sequence adjusting embodiments of the type A card and the type B card, the device can read the RAID card manufacturer information by the BMC on the server, obtain the relation between the physical port of the RAID card and the hard disk sequence number in the system by comparing the BIOS firmware in the PCH, and dynamically adjust the mapping relation between the input pin and the output pin by changing the temporary storage of the firmware in the Expander card, so that the corresponding relation of the physical ports of the RAID cards of different manufacturers or different types can accord with the hard disk slot position sequence designed by the hard disk backboard of the server, thereby further realizing the automatic dynamic reforming of the hard disk sequence. The original slot position of the backboard is designed and finished, and the slot position on the backboard is designed for the RAID card of the type A, namely the RAID card of the type A can be directly used to realize the RAID function of 8 hard disks on the backboard when the RAID card of the type B is not used, when the RAID card of the type B is adopted, the device using the method only needs to modify the firmware of the RAID card of the type B connected with the RAID card of the type A, and the server using the RAID card of the type A and the RAID card of the type B is matched with and modifies the configuration of the RAID card of the type A to realize the exchange of RAID card types of different types.

Compared with the traditional method for adjusting the disk sequence of the hard disk by updating the firmware of the RAID card, the technical scheme of the invention does not need to consume excessive manpower and time, and can avoid the problem of update error or update failure of the firmware of the RAID. Simultaneously compare with the different cable mode adjustment dish preface mode of RAID card collocation, not only solved and increased the big problem of work load that the cable leads to, but also avoided producing the risk that line assembly personnel can cause hard disk dish preface because of collocation wrong RAID card cable.

In another embodiment, referring to fig. 4, the present invention further provides a method for adjusting a disk sequence of a hard disk, where the method includes the following steps:

s100, connecting a plurality of physical ports of the RAID card with a plurality of input pins of the Expander card in a one-to-one manner, wherein each physical port corresponds to a hard disk serial number in an operating system;

s200, connecting a plurality of hard disk slot positions inserted with hard disks with a plurality of output pins of an Expander card in a one-to-one manner, wherein each hard disk slot position corresponds to a slot position serial number on a backboard, and the number of the hard disk slot positions is the same as that of the physical ports of the RAID card;

s300, reading the board card information of the RAID card by using a control assembly, determining the hard disk serial number of each physical port of the RAID card according to the board card information, and adjusting the mapping relation of the input pin and the output pin of the Expander card based on the hard disk serial number of each physical port so as to enable the serial numbers of the hard disk slot position and the slot position corresponding to each pair of mutually communicated physical ports to be the same as the serial number of the hard disk.

In another embodiment, usually, firmware in the Expander card defaults to a mapping relationship between a set of input pins and output pins, so that there is a case where a part of RAID cards can be directly used without modifying firmware of the Expander card, and for this, the disk order adjusting method for another hard disk provided by the present invention includes the following steps:

firstly, after the system is powered on, actively reading information provider ID (identity) and equipment ID (identity) of a manufacturer, a model and the like of a RAID card on the system through an I2C interface by the aid of a BMC (baseboard management controller);

secondly, reading RAID card information read by the BMC through an LPC or SPI interface by the PCH;

thirdly, comparing the Physical ports (Physical ports, Phy for short, namely hardware high-speed signal link paths) of the RAID card with the corresponding relation of the Physical input ports of the Expander by using the BIOS firmware in the PCH, and determining the hard disk serial number corresponding to each Physical port in the system;

step four, the PCH dynamically changes the output pin sequence into a correct disk sequence which is in accordance with the hard disk slot position sequence on the hard disk backboard of the server by the firmware in the Expander card through the I2C interface in a mode of dynamically changing a temporary storage;

and step five, the PCH also transmits image information through a VGA interface of the BMC, and displays the correct hard disk sequence corresponding to the RAID card under a BIOS setting menu (or OS).

And sixthly, transmitting the lighting data of the hard disk to the CPLD for lamp number decoding through the VPP and SGPIO interfaces by the PCH, transmitting the lighting data to each hard disk slot position on a hard disk backboard of the system through the CPLD via the GPIO interface, and realizing the lighting function (Active LED/Locate LED/Fault LED) according to a corresponding hard disk sequence.
