Description
Technical Field
The present invention relates to the field of servers, and more particularly, to a module for controlling a disk sequence with multiple backplanes and a server.
Background
With the proliferation of personal audio/video media and the increasing demand of personal handheld mobile devices to upload to cloud storage servers, the number of storage servers has increased. The storage server is used for storing data, which is very important and precious, and once the data is lost, the data can have very serious consequences, so the storage server needs to perform backup repair in addition to storing the data, so the shadow of a RAID (Redundant Array of independent Disks) card can be often seen in the storage server. Because the storage server stores a lot of data, the storage server also has a lot of hard disks.
Because there are many storage hard disks and the need of later maintenance, it is desirable that the disk order of the hard disks is well determined when the storage system is planned, and the hard disks with problems are conveniently positioned when maintenance is performed. The hard disk backplane is upstream from the RAID card, and usually the backplane is connected in the order of Port0, Port1, Port3, and Port4 of the RAID card (taking 4 ports as an example), and a SAS Expander (Serial Attached Small Computer System Interface Expander) on the hard disk backplane theoretically starts the hard disk from Port 0.
With the existing architecture, manufacturers do not guarantee that the disk order is arranged according to the architecture. In actual use, the hard disk order is determined according to the connection speed of the RAID card and the back plate. In addition, if the manufacturers of the RAID cards and the SAS expanders on the hard disk backplanes are different, compatibility problems may also occur, and the backplanes are all the same, and if the CPLD on each backplane is used to control the SAS Expander power supply, the material number of each backplane is different, which increases the cost.

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.
FIG. 1 is a schematic diagram showing the connection relationship between RAID cards and a backplane in the prior art, as shown in FIG. 1, the Power of serial small computer system interface expansion cards is output from VR, the enabling pin (Enable) of VR divides the voltage with R1 and R2, i.e. VR is enabled when the backplane is powered on, then Vout outputs the voltage, therefore the Power Good pin (Power Good) signal is changed from Low to High, the Reset pin (Reset) signal of serial small computer system interface expansion cards is Reset, the serial small computer system interface expansion cards start to work, theoretically, the hard disk start sequence is started according to Port0 of RAID cards, the architecture can know that the hardware architecture of each backplane is the same, the Power-on time is the same, but each serial small computer system interface expansion card still has some differences, the fastest SAS Expander may not be BP0 connected with RAID cards, so there is no guarantee that the disk order is long from Port 0.
RAID refers to a redundant array of independent disks, referred to as a disk array for short, and is mainly used for server storage, to improve the speed and stability of storage devices, and to protect data. Shared resources or unshared resources in a network are data, and storage media are needed for storing the data, and currently, most applications are magnetic hard disks, tape libraries and solid state disks with flash memory particles. The main task of most servers (without supercomputer or other scientific computer servers) is to send and receive data to and from the network at high speed for 24 hours. For an individual user, the read-write speed of the current hard disk completely meets the individual requirement, but for a server, even the current solid state disk with the highest response speed cannot meet the requirement of the server on high-speed data response, so that the RAID is needed to form an array by disks to make up the deficiency. The main implementation modes of RAID are divided into a hardware RAID mode and a software RAID mode. Hardware RAID: the hardware RAID adapter card integrated with the processor is used for processing the RAID tasks, and the CPU resources of the host computer are not occupied. (current south bridge chips generally support 4 SATA (Serial Advanced Technology Attachment) controls). It can be seen from fig. 1 that four ports P0, P1, P2 and P3 are included in the RAID card, each port being controlled by a different SAS.
In a first aspect of the embodiments of the present invention, an embodiment of a module for controlling a disk sequence with multiple backplanes is provided. Fig. 2 is a schematic diagram of an embodiment of the multi-backplane module for controlling a disk sequence according to the present invention, and as shown in fig. 2, the multi-backplane module for controlling a disk sequence includes the following components:
a RAID card; the system comprises a RAID card, a plurality of backing plates and a reset pin, wherein the RAID card is connected with the backing plates, each backing plate comprises an SAS expansion card and a VR (virtual reality) power supply, the SAS expansion cards are connected with a plurality of hard disks, the VR power supply comprises an enabling pin and a power supply normal indication pin, the reset pin of the SAS expansion card is connected with the power supply normal indication pin, signal joints (heads) are arranged on the enabling pin and the power supply normal indication pin, and the signal joints of the power supply normal indication pin are connected with the signal joints on the enabling pins on the adjacent backing plates through the reset pin.
In some embodiments, the plurality of backplanes are arranged in a preset hard disk boot disk order from small to large. For example, the disk ranks of 12 hard disks in the back plane BP0 are 1 to 12, the disk ranks of 12 hard disks in the back plane BP1 are 13 to 24, the disk ranks of 12 hard disks in the back plane BP2 are 25 to 36, and the disk ranks of 12 hard disks in the back plane BP3 are 37 to 48. That is, a plurality of backplanes may be arranged in a disk-order from small to large arrangement as shown in fig. 2.
However, this is not limited to the sorting manner, and the start-up sequence of the hard disk in the embodiment of the present invention is determined by the connection manner of the backplane, for example, the backplane may be arranged according to the sequence of BP1, BP0, BP3, and BP2, the enable pin in BP1 is not connected to other signal connectors, the signal connector of the power normal indication pin in BP1 is connected to the signal connector of the enable pin in BP0, the signal connector of the power normal indication pin in BP0 is connected to the signal connector of the enable pin in BP3, the signal connector of the power normal indication pin in BP3 is connected to the signal connector of the enable pin in BP2, and the power normal indication pin in BP2 is not connected to other signal connectors. Thus, the BP1 is the first backplane to be started, the hard disks in the BP1 are started in sequence, then the BP1 drives the BP0 to be started, the hard disks in the BP0 are started in sequence, and so on.
In some embodiments, the VR power source is configured to: and in response to the enabling pin receiving a power-on signal, pulling up the power supply normal indication pin to enable the reset pin to complete resetting. When the enable pin receives the power-on signal, the VR pulls up the PG signal, thereby pulling up the reset signal of the serial connection small computer system interface expansion card to enable the reset pin to complete resetting.
In some embodiments, the SAS expander card is configured to: and responding to the reset pin to complete resetting, and enabling the plurality of hard disks connected with the SAS expansion card to be sequentially started according to a disk sequence. The reset pin is reset to enable the serial connection small computer system interface expansion card to start working, namely, a plurality of hard disks connected with the serial connection small computer system interface expansion card can be started in sequence.
In some embodiments, the SAS expander card is configured to: and responding to the reset pin to complete resetting, and sending a power-on signal to an enabling pin connected with the reset pin through a signal connector. The reset pin completes resetting, so that a power-on signal can be sent to the enabling pin of the connected backboard, and the hard disk in the next backboard is driven to start.
The back panel of the storage server usually has a back panel for both the front panel and the back panel, so the cable topology may be connected to the back panel after the front panel is strung, the cable may be very long, and the cable routing space needs to be reserved in the cable routing layout.
