[ background Art ]
The existing high availability system (highavailabilitysystem) technology is used for providing two data access paths (portA and portB) to support the access of two remote hosts to the dual-port solid state disk, and the disadvantage is that: when a single port solid state disk (single port ssd) is inserted, the single port solid state disk can only be connected to a single port, and when the single port solid state disk is inserted to connect to the port a, the single port solid state disk can be connected to the port a, and when the port a is disconnected, a data access path is usually switched randomly by a system supporting two remote hosts to access the dual port solid state disk, so that the system can connect the port a connected to the single port solid state disk to the remote host, and when the port b connected to the single port solid state disk is not connected to the remote host, the single port solid state disk inserted to connect to the port a is connected to the remote host, and the system is unstable in access.
[ invention ]
The technical problem to be solved by the present invention is to provide a server device capable of overcoming the drawbacks of the prior art.
To solve the above technical problem, the server device of the present invention includes: a first server, a second server and an input/output device.
The input/output device comprises a read/write interface module, a first input/output module and a second input/output module. The read-write interface module is used for electrically connecting a solid state disk, and a hard disk identifier of the solid state disk corresponds to one of a single-port solid state disk and a double-port solid state disk. The first input/output module is electrically connected between the first server and the read/write interface module, and stores a white list data, wherein the white list data records a plurality of default identifiers, and each default identifier corresponds to one of a single-port solid state disk and a dual-port solid state disk, preferably, the white list data only has the default identifier corresponding to the single-port solid state disk, but does not have the default identifier corresponding to the dual-port solid state disk, that is, the plurality of default identifiers recorded by the white list data all correspond to the single-port solid state disk. The second input/output module is electrically connected between the second server and the read-write interface module and stores the white list data.
When the first input/output module detects that the read/write interface module is connected to the solid state disk, whether the solid state disk electrically connected with the read/write interface module connected with the solid state disk belongs to a single-port solid state disk or not is identified according to the white list data, if so, the first server and the read/write interface module connected with the single-port solid state disk are in an online state, and at least one of reading and writing is performed on the solid state disk connected with the read/write interface module.
When the second input/output module detects that the read-write interface module is connected with the solid state disk and the solid state disk electrically connected with the read-write interface module connected with the solid state disk is identified to belong to the single-port solid state disk according to the white list data, the second server and the read-write interface module connected with the single-port solid state disk are in a disconnected/disconnected state, that is, the second server cannot communicate with the corresponding solid state disk through the read-write interface modules.
Compared with the prior art, when the white list data stored by the first machine service manager and the second machine service manager are utilized to identify that the single-port solid state disk is connected to the read-write interface module, the signal transmission path provided by the second exchanger is forcibly closed, and only the signal transmission path between the single-port solid state disk and the first server provided by the first exchanger is reserved, so that the functions of simultaneously supporting the single-port solid state disk and avoiding unstable systems are achieved.
[ description of the drawings ]
Other features and advantages of the present invention will become apparent from the following description of the embodiments with reference to the drawings, in which:
fig. 1 is a system architecture diagram of an embodiment of a server device of the present invention.
[ detailed description ] of the invention
Before the present invention is described in detail, it should be noted that in the following description, like components are denoted by the same reference numerals.
Referring to fig. 1, an embodiment of the server device of the present invention can be generally used for accessing multiple Solid-state disks (SSDs), and is combined with a hardware architecture supporting dual-port SSDs and a firmware technology supporting white list identification, so that the server device does not have unstable system access even if the server device is applied to a single-port SSD. The server apparatus comprises a first server 1, a second server 2 and an input-output device 3.
The input/output device 3 includes a plurality of read/write interface modules 4, a first input/output module (I/o module) 31 and a second input/output module 32, where the plurality of read/write interface modules 4 are, for example, N number of read/write interface modules 4, and N is equal to or greater than 1, where N is a positive integer. In general, the first input/output module 31 is operated in an active mode (active mode), the other second input/output module 32 is operated in a passive mode (passive mode), and when the first input/output module 31 is abnormal, firmware update is performed or maintenance is performed, the other second input/output module 32 is switched from the passive mode to the active mode to execute the work originally performed by the first input/output module 31.
Each read-write interface module 4 is configured to electrically connect to a solid state disk 5, where the solid state disk 5 has a hard disk identifier, and the hard disk identifier corresponds to one of a Single-port solid state disk (Single-port ssd) and a Dual-port solid state disk (Dual-port ssd). Each of the plurality of read/write interface modules 4 includes a dual port driver (dualportdriver), that is, each of the plurality of read/write interface modules 4 has two ports (for example, portA and portB) for connecting to the solid state disk 5, in this embodiment, the port portA corresponds to the first input/output module 31, and the port portB corresponds to the second input/output module 32, that is, one of the plurality of read/write interface modules 4 is correspondingly connected to the port portA and the first input/output module 31 in a preset state, and the other of the plurality of read/write interface modules 4 is correspondingly connected to the port portB and the second input/output module 32 in a preset state, when the solid state disk 5 inserted and connected to one of the read/write interface modules 4 is a single-port solid state disk, the solid state disk 5 is only connected to the port portA corresponding to the first input/output module 31, however, since the first input/output module 31 and the second input/output module 32 detect whether the read/write interface 4 is connected to the solid state disk 5 through the read/write interface module 4, the first input/output module 31 and the second input/output module 32 only can know whether the solid state disk 5 is connected to the read/write interface module 4 through the read/write interface module 4, and cannot distinguish which port (portA or portB) on the read/write interface module 4 is used for connecting the solid state disk 5 to the read/write interface module 4, for example, the port portA which is connected by the single-port solid state disk and the dual-port solid state disk, or the port portB which is connected by the dual-port solid state disk, when the technology is not implemented, the second server 2 transmits data to the single-port solid state disk connected by the read/write interface module 4 through the second input/output module 32, since the PortB of the read-write interface module 4 is not connected to the single-port solid state hard disk, the read-write interface module 4 for connecting the PortB with the corresponding second input-output module 32 is not connected to the single-port solid state hard disk in which the PortA is inserted and the second input-output module 32, that is, when the second server 2 transmits data to the single-port solid state hard disk connected to one of the read-write interface modules 4 through the second input-output module 32, the second input-output module 32 is connected to the read-write interface module 4 as well, and the read-write interface module 4 is detected to be connected to the solid state hard disk 5, but the transmitted data is not actually connected to the single-port solid state hard disk, so that the data is lost or the error of transmission failure is caused, and the system is unstable.
In this embodiment, the first input/output module 31 is electrically connected between the first server 1 and each read/write interface module 4, so as to respectively communicate with the first server 1 and each read/write interface module 4, and store a white list data, where the white list data records a plurality of default identifiers, and each default identifier corresponds to one of a single-port solid state disk and a dual-port solid state disk, and preferably, each default identifier also records one of a single-port solid state disk and a dual-port solid state disk. Preferably, the white list data only has a default identifier corresponding to the single-port solid state disk, but does not have a default identifier corresponding to the dual-port solid state disk, that is, the plurality of default identifiers of the white list data record correspond to the single-port solid state disk. The second input/output module 32 is electrically connected between the second server 2 and each read/write interface module 4 to communicate with the second server 2 and each read/write interface module 4, respectively, and stores the white list data. When the first input/output module 31 detects that any one of the read/write interface modules 4 is connected to the solid state disk 5, it is identified according to the white list data whether any one of the preset identifiers in the white list data is met by the solid state disk 5 electrically connected to the any one of the read/write interface modules 4, if yes, the connection between the first server 1 and the N read/write interface modules 4 is maintained, and the definition of connection is to provide the function of transmitting data with the read/write interface module 4 or accessing data to the solid state disk 5 corresponding to the read/write interface module 4, that is, the first server 1 can transmit data with the read/write interface module 4 or read/write data stored in the solid state disk 5 corresponding to the read/write interface module 4. When the second i/o module 32 detects that any of the read/write interface modules 4 is connected to the solid state disk 5, and identifies that the solid state disk 5 electrically connected to the N read/write interface modules 4 belongs to a single-port solid state disk according to the whitelist data, the connection between the second server 2 and the N read/write interface modules 4 is disconnected, so that the second server 2 disconnected from the read/write interface modules 4 cannot communicate with the corresponding solid state disk 5 through the read/write interface modules 4, wherein the disconnection of the connection between the second server 2 and the read/write interface modules 4 means that the second server 2 is not allowed to transmit data or that the function of accessing the solid state disk 5 corresponding to the read/write interface modules 4 is not provided, that is, the second server 2 cannot transmit data with the read/write interface modules 4 or cannot access the solid state disk 5 corresponding to the read/write interface modules 4.
The first input/output module 31 includes a first switch 41, a first station service manager (ESM) 51, and a first system-on-a-chip 61.
The first switch 41 is electrically connected between the N read-write interface modules 4 and the first server 1 to communicate with the read-write interface modules 4 and the first server 1, and is switched between a conducting mode and a closing mode according to a first control signal, wherein the conducting mode is defined by the first server 1 transmitting data to any read-write interface module 4 and receiving data from any read-write interface module 4 through the first switch 41, and the closing mode is defined by the first server 1 failing to transmit data to any read-write interface module 4 through the first switch 41, failing to receive data from any read-write interface module 4 through the first switch 41, and failing to read and write any solid state disk 5 corresponding to the read-write interface module 4 through the first switch 41. The first switch 41 comprises a peripheral component interconnect express switch (PCI-ESwitch).
The first machine service manager 51 is electrically connected to the N read/write interface modules 4 and the first switch 41, and stores the whitelist data, wherein the whitelist data stored in the first machine service manager 51 can be newly added, deleted, edited or replaced by a representational state transfer command (representational state transfer command) through a remote computer (not shown) and through a network, wherein the whitelist data stored in the first machine service manager 51 is periodically added, deleted, edited or replaced by the representational state transfer command (representational state transfer command), the remote computer can also communicate with the first machine service manager 51 through a network and through an intelligent platform management interface (IntelligentPlatform ManagementInterface, IPMI) to edit or replace the whitelist data stored in the first machine service manager 51, but the technology of adding, deleting, editing or replacing whitelist data is not limited thereto, wherein the first machine service manager 51 operating in an active mode periodically sends an instruction to the second machine service manager 52 operating in a passive mode to the second machine service manager 52 or a part of the second machine service manager in a passive mode, the second machine service manager 52 also receives an instruction from the second machine service manager in a backup mode or a part of the second machine service manager in a backup mode (IPMI) which the second machine service manager 51 receives the updated data from the second machine service manager in a backup mode or a part of the second machine service manager in a backup mode (IPMI) and the second machine service manager) receives the updated data from the second machine service manager in a second mode, the second service manager 52 updates the stored white list data according to the white list data transmitted by the first service manager 51 so that the first service manager 51 and the second service manager 52 have the same white list data, and when the manager edits/modifies the white list data stored by the second service manager 52 via a remote computer (not shown) and a network, the second service manager 52 also transmits the edited or substituted at least part of the updated white list data (which may be transmitted with only the updated part or the whole white list data) to the first service manager 51, so that the first service manager 51 updates the stored white list data according to the white list data transmitted by the second service manager 52 so that the first service manager 51 and the second service manager 52 have the same white list data. The first service manager 51 defaults to an active mode, where the active mode is defined as when the first service manager 51 is operating normally, presetting that the first service manager 51 is in an active mode and communicates with the first service manager 51 via the second service manager 52, so that the second service manager 52 is in a passive mode, when the first service manager 51 is operating abnormally, communicating with the first service manager 51 via the second service manager 52 (e.g., there are other communication interfaces (not shown) between the first service manager 51 and the second service manager 52), so that the second service manager 52 is in an active mode, the second service manager determines whether the first service manager 51 is abnormal according to the communication status with the first service manager 51 or according to the periodically monitored operation status of the first service manager 51, if the communication between the second service manager 52 and the first service manager 51 fails, or if the second service manager 52 detects that the first service manager 51 transmits a signal indicating the operation of the first service manager 51, the second service manager 52 determines that the first service manager 51 is abnormal, further, taking the first service manager 51 in the active mode as an example, the first service manager 51 in the active mode detects whether the read/write interfaces 4 are connected to the solid state disk 5, and further detects that the solid state disk 5 is connected to the corresponding read/write interface module 4, and belongs to a single-port solid state disk, the first switch 41 is switched to a conducting mode according to a first control signal of the first machine service manager 51, so that the first machine service manager 51 connects the first system single chip 61 to the solid state disk 5 through the first switch 41 and the read-write interface module 4. The specific technology for detecting that the solid state disk 5 is connected to the read-write interface module 4 is as follows: the first service manager 51 periodically communicates with a Complex Programmable Logic Device (CPLD) (not shown) via a serial general purpose input/output (SGPIO) protocol, to obtain the parameters stored in the register (register) of the CPLD, the parameters indicate the existence status of the solid state disk 5 (for example, a logic 1 is that the solid state disk 5 exists, a logic 0 is that the solid state disk 5 does not exist), wherein, the solid state disk 5 will transmit its current signal to the General-purpose input/output port (GPIO) of CPLD, so as to know the existence state of the solid state disk 5, and the CPLD controls the LED lamp corresponding to the solid state disk on a backboard (not shown) according to the operation/existence state of the solid state disk 5, wherein the first I/O module 31 and the second I/O module 32 are respectively connected to the back board, and the back board is respectively connected to the read/write interface modules 4, wherein the CPLD is disposed on the back board and is connected to the read-write interface modules 4, the first machine service manager 51 and the second machine service manager 52, respectively, and in another embodiment, the first input/output module 31 and the second input/output module 32 have a CPLD respectively, the first machine service manager 51 and the second machine service manager 52 are respectively connected with the read-write interface modules through corresponding CPLDs, so that the read-write interface module 4 can obtain the status signals of the corresponding solid state disk 5, wherein the status signal includes any one or a combination of more than two of a present signal, an operation signal and a fault signal; when the first machine service manager 51 operating in the active mode by default is abnormal, for example, in abnormal states such as performing hardware maintenance, firmware update, and module restarting, the second machine service manager 52 is in the active mode, the second machine service manager 52 in the active mode will perform corresponding actions performed by the first machine service manager 51 in the active mode, for example, according to whether the solid state disk 5 connected to the read/write interface module 4 is a single-port solid state disk or a dual-port solid state disk, the second switch 42 is controlled to be in the on mode or the off mode, wherein when the first machine service manager 51 is in the active mode, that is, the first input/output module 31 is also correspondingly operated in the active mode, and when the second machine service manager 52 is in the passive mode, that is, the second input/output module 32 is also correspondingly operated in the passive mode, in this embodiment, the first machine service manager 51 is operated in the single-port solid state disk, the second input/output module 52 is also correspondingly operated in the single-port mode, and the solid state disk is prevented from being disconnected from the second solid state disk 2 when the solid state disk 5 connected to the read/write interface module 4 is connected to the second solid state disk 2, and the data storage module is disconnected from the second solid state disk 2. In another embodiment, when the first machine service manager 51 operates abnormally, and the second machine service manager 52 operates in the active mode instead, and the second machine service manager 52 obtains the solid state disk 5 connected to the read-write interface module 4 according to the white list data and is a single-port solid state disk, the read-write interface modules 4 corresponding to the solid state disk 5 corresponding to the white list data can be reconfigured by the second machine service manager operating in the active mode, so that the read-write interface modules 4 corresponding to the solid state disk 5 corresponding to the white list data can be connected to the ports PortB corresponding to the second input/output module 32 and the second switch 42, and therefore, when the first machine service manager 51 operates abnormally, the second server 2 can perform data access on the single-port solid state disk corresponding to the white list data by switching the second input/output module 32 operating in the active mode instead.
Next, in the present embodiment, the first machine service manager 31 accesses the hard disk identifier of the solid state disk 5, and the specific technology for accessing the hard disk identifier is further described as follows: the first machine service manager 51 sends an inquiry signal to the N read-write interface modules for inquiry respectively in a broadcast manner, and the read-write interface module 4 connected to the solid state disk 5 transmits a response signal to the first machine service manager 51 according to the inquiry signal, where the response signal includes the hard disk identifier of the connected corresponding solid state disk 5. And the first machine service manager 51 compares the received hard disk identifier with the white list data, and when the hard disk identifier is compared to be a single-port solid state hard disk, the first machine service manager 51 sends the first control signal to enable the first switch 41 to operate in the conducting mode. The first machine service manager 51 includes a Baseboard Manager (BMC), which performs handshake communication (handshake) with the solid state disk 5 electrically connected to the read/write interface module 4 through a management component transport protocol bus (ManagementComponent TransportProtocolSystemManagementBus, mctpeversmbus), and transmits the first control signal to the first switch 41 through a Memory-mapped remote procedure call system management bus (Memory-mappedRemote ProcedureCallSystemManagementBus, MRPCoverSMBUS). The baseboard manager is used for managing and monitoring the operation status of the first input/output module 1, such as monitoring the temperature, fans, CPU and other components (not shown) of the first input/output module 1, and can communicate with a remote computer (not shown) to report the monitored error message and manage and control the electronic components of the first input/output module 1 according to the instruction of the remote computer. The first i/o module 1 is operated in either an active or a passive mode, i.e. it is determined that the substrate manager of the first i/o module 1 is operated in either the active or the passive mode.
The first system single chip 61 is electrically connected between the first switch 41 and the first server 1, and is used for executing an operating system of the first input/output module 31, for example, when the remote first server 1 needs to read and write data of the solid state disk 5, for example, when a manager uses a computer or pen to connect to the remote first server 1 via a network to request for reading and writing the data of the solid state disk 5, or the first server 1 needs to monitor the access data of the solid state disk 5, the first server 1 is connected to the first system single chip 61 in the first input/output module 31 via the network and reads and writes the data stored in the solid state disk 5 via the first switch 41, thereby completing the task to be executed, that is, when the first server 1 issues a read/write command to the first system single chip 61, the first system single chip 61 transmits the data from the first server 1 to the corresponding solid state disk 5 via the first switch 41 according to the received read/write command, or transmits the data from the corresponding to the solid state disk 5 via the read/write interface module 4 to the corresponding solid state disk 4 via the first switch 4.
The second input/output module 32 includes a second switch 42, a second equipment service manager 52, and a second system-on-a-chip 62 electrically connected between the second switch 42 and the second server 2.
The second switch 42 is electrically connected between the N read-write interface modules 4 and the second server 2 to communicate with the read-write interface modules 4 and the second server 2 respectively, and is switched between an on mode and an off mode according to a second control signal, wherein the on mode is defined to allow the second server 2 to transmit data to any read-write interface module 4 through the second switch 42 and allow the second server 2 to receive data from any read-write interface module 4, and the off mode is defined to allow the second server 2 to not transmit data to any read-write interface module 4 through the second switch 42 and not receive data from any read-write interface module 4 through the second switch 42.
The second service manager 52 is electrically connected to the N read-write interface modules 4 and the second switch 42, wherein the second service manager 52 and the second switch 42 are electrically connected to the read-write interface modules 4 through different communication interfaces, and the second service manager 52 stores the whitelist data. The second service manager 52 defaults to a passive mode or is in a passive mode according to its communication with the first service manager 51, where the definition that the second service manager 52 is in the passive mode is that when the second service manager 52 detects that the solid state disk 5 belongs to a single-port solid state disk, the second system-on-chip 62 cannot be connected to the solid state disk 5 through the second switch 42. In more detail, the second service manager 52 accesses the hard disk identifier of the solid state disk 5, and compares the hard disk identifier with the white list data, and when the hard disk identifier is compared to be a single-port solid state disk, the second service manager 52 sends the second control signal to make the second switch 42 operate in the off mode. In another embodiment, when the second service manager 52 is in the passive mode, the first service manager 51 in the active mode communicates with at least one of the read-write interface modules 4 and obtains that the corresponding solid state disk 5 is a single-port solid state disk to issue a control switching command, and the second service manager 52 in the passive mode generates and transmits the second control signal to the second switch 42 according to the control switching command, so that the second switch 42 operates in the off mode. The specific technology of the second machine service manager 52 detecting that the solid state disk 5 is inserted into the read/write interface module 4 and the specific technology of accessing the hard disk identifier are the same as the first machine service manager 51 described above, and therefore will not be repeated. The second service manager 52 includes a baseboard manager (not shown) that performs handshake communication (handshake) with the solid state disk 5 electrically connected to the read/write interface module 4 through an mctpaver SMBUS, and transmits the second control signal to the second switch 42 through an MRPCoverSMBUS.
In summary, the above embodiment has the following advantages: 1. the white list data stored by the first machine service manager 51 and the second machine service manager 52 are utilized to identify that the single-port solid state disk is connected to the read-write interface module 4, then the signal transmission path (PortB) provided by the second switch 42 is forcibly closed, and only the signal transmission path (PortA) between the single-port solid state disk and the first server 1 provided by the first switch 41 is remained, so that the functions of simultaneously supporting the single-port solid state disk and avoiding unstable systems are achieved. 2. The unused PortB is forcibly closed by the white list data, so that the hardware originally used for supporting the Dual-portSSD can be prevented from being modified, and the effect of saving the cost is achieved. 3. The Dual-port SSD is supported, the Single-port SSD can be supported, and the inconvenience of a client in using different types of solid state disks is avoided.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
