Those skilled in the art will appreciate that the hardware configuration shown in fig. 1 is not intended to limit the present invention, and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
With continued reference to FIG. 1, the memory 1005 of FIG. 1, which is one type of computer storage medium, may include an operating system, a network communication module, a user interface module, and a TCG-Opal based RAID card management program. The processor 1001 may call a TCG-Opal-based RAID card management program stored in the memory 1005, and execute the TCG-Opal-based RAID card management method according to the embodiment of the present invention.
In a second aspect, an embodiment of the present invention provides a TCG-Opal-based RAID card management method.
In an embodiment, referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a TCG-Opal-based RAID card management method according to the present invention. As shown in fig. 2, the TCG-Opal-based RAID card management method includes:
step S10, when the RAID card is powered on, selecting any solid state disk from all solid state disks which are in communication connection with the RAID card as a main solid state disk, wherein original data required by a TCG-Opal protocol stack are stored in all the solid state disks;
in this embodiment, referring to fig. 3, fig. 3 is a schematic configuration diagram of an embodiment of a TCG-Opal-based RAID card management method according to the present invention. As shown in fig. 3, communication is performed between the host and the RAID card, and between the RAID card and each Solid State Disk (SSD) via the Pcle bus. When the RAID card is powered on, scanning each Solid State Disk (SSD) in communication connection with the RAID card, and then selecting any solid state disk from the SSD in communication connection with the RAID card as a main solid state disk, wherein original data required by a TCG-Opal protocol stack are stored in each solid state disk. Further, after the main solid state disk is selected, the electronic serial number of the main solid state disk is stored, so that when the RAID card is electrified again, the main solid state disk is directly found through the electronic serial number, and data are read from the main solid state disk.
Step S20, loading the original data in the main solid state disk into a system of the RAID card for initializing the TCG-Opal protocol stack based on the original data.
In this embodiment, the original data required for reading the TCG-Opal protocol stack from the master solid state disk is loaded into the system of the RAID card, so that the TCG-Opal protocol stack is initialized based on the original data required for reading the TCG-Opal protocol stack from the master solid state disk.
In this embodiment, when the RAID card is powered on, any solid state disk is selected from the solid state disks that establish communication connection with the RAID card as a master solid state disk, where original data required by the TCG-Opal protocol stack is stored in each solid state disk; and loading the original data in the main solid state disk into a system of a RAID card for initialization of a TCG-Opal protocol stack based on the original data. Through the embodiment, the TCG-Opal protocol stack is initialized through data in the main solid state disk which establishes communication connection with the RAID card, and a complete TCG-Opal protocol stack is realized on the RAID card, so that the problem that the RAID card and the solid state disk which supports the TCG-Opal protocol stack and establishes communication connection with the RAID card cannot be managed through the TCG-Opal protocol stack in the prior art because the TCG-Opal protocol stack is not realized on the RAID card is solved.
Further, in an embodiment, referring to fig. 4, fig. 4 is a flowchart illustrating a second embodiment of a TCG-Opal-based RAID card management method according to the present invention. As shown in fig. 4, after step S20, the method includes:
step S30, determining an alignment mode of a logic space supported by TCG-Opal based on the stripe size of data sent by the RAID card and the number of solid state disks establishing communication connection with the RAID card;
and step S40, after receiving the instruction for setting the logic space sent by the host, uniformly setting the logic space in each solid state disk, wherein the logic space in the instruction for setting the logic space sent by the host conforms to the alignment mode of the logic space supported by the TCG-Opal protocol stack.
In this embodiment, a RAID stripe (strip) is a method of dividing continuous data into data blocks of the same size and writing each data block to a different disk in the array. Since the IO data accessed this time are distributed in different solid state disks, in order to ensure that the RAID card uniformly sets the logical space in each solid state disk after receiving the instruction for setting the logical space sent by the Host (Host), before the Host sends the instruction for setting the logical space to the RAID card, the alignment method of the logical space supported by the TCG-Opal is determined based on the size of the stripe where the RAID card sends data and the number of the solid state disks which establish communication connection with the RAID card. After the logic spaces are uniformly arranged in each solid state disk, when data are read and written in the subsequent normal process, the permission of the RAID card for reading the data and the permission of the data writing in the data can be respectively controlled based on the read-write permission of each solid state disk hardware in communication connection with the RAID card, namely, if each solid state disk hardware in communication connection with the RAID card can only read the data, and if each solid state disk hardware in communication connection with the RAID card can only write the data, thereby ensuring that the speed of reading and writing the data is not influenced by a TCG-Opal protocol stack.
Specifically, if the stripe size of the data sent by the RAID card is 8KB, and the number of the solid state disks establishing communication connection with the RAID card is 4, the alignment manner of the logic space supported by the TCG-Opal is a multiple of 4 × 8, that is, a multiple of 32. The host sends an instruction to set the logical space to the RAID card to set a logical space of 32KB or a logical space of 64KB or a logical space of 128 KB. It is easy to think that the logical space in the instruction sent by the machine for setting the logical space is in accordance with the alignment mode of the logical space supported by the TCG-Opal protocol stack as long as the logical space is a multiple of 32. When the host sends a command for setting the logic space to the RAID card, wherein the command is used for setting the logic space of 32KB, each solid state disk in the 4 solid state disks is provided with the logic space of 8 KB; when the host sends a command for setting the logic space to the RAID card, the command is set to be the logic space of 64KB, and each solid state disk in the 4 solid state disks is set to be the logic space of 16 KB; when the host sends an instruction to the RAID card to set the logical space to 128KB, each of the 4 solid state disks sets 32KB of logical space.
Further, in an embodiment, with reference to fig. 4 continuously, after the step of uniformly setting the logic spaces in the solid state disks after receiving the instruction for setting the logic spaces sent by the host, the method includes:
and S50, when a key command for replacing the logic space is received, replacing the keys of the solid state disks corresponding to the logic space.
In this embodiment, since the start position, the length, the read-write permission, and the key corresponding to the logical space are specified in the TCG-OPAL protocol stack, when the key of the logical space is replaced, the key corresponding to the logical space specified in the TCG-OPAL protocol stack is replaced. And because the logic space is uniformly arranged in each solid state disk, when a key command for replacing the logic space is received, the key of each solid state disk corresponding to the logic space is replaced. After the key is replaced, the written data is encrypted through the AES engine of each solid state disk in communication connection with the RAID card and based on the replaced key, the read data is decrypted, the data of a user is not encrypted by using Host application software, and the speed of reading and writing the data is guaranteed not to be influenced by main machine resources and a TCG-Opal protocol stack.
Further, in an embodiment, with reference to fig. 4 continuously, after the step of replacing the key of each solid state disk corresponding to the logical space when the key instruction for replacing the logical space is received, the method includes:
and S60, encrypting the replaced secret key of each solid state disk based on the user identification code and the identification code of the logic space, wherein the encrypted secret key storage address is not fixed.
In this embodiment, in order to ensure consistency of the secret key, the replaced secret key of each solid state disk is encrypted based on the user identification code and the identification code of the logical space, that is, a HASH value is generated by using a HASH function according to the identification code of the user, the identification code of the logical space, and the replaced secret key of the solid state disk, and the secret key is authenticated by HASH value verification when the secret key is used next time. The encrypted key storage address is not fixed, that is, the position of the encrypted key is not fixedly stored in a certain position but is dynamically modified, so that the risk of the key being leaked is reduced, and the data security is improved.
Further, in an embodiment, after the step of loading the data in the master solid state disk into the system of the RAID card for initializing the TCG-Opal, the method further includes:
when the RAID card is electrified again, verifying TCG-Opal protocol stack data in the main solid state disk;
if the verification is passed, loading the data in the main solid state disk into a system of the RAID card for initializing the TCG-Opal protocol stack based on the data in the main solid state disk;
and if the verification fails, selecting any solid state disk from the rest solid state disks which are in communication connection with the RAID card as a target solid state disk, and loading the data in the target solid state disk into a system of the RAID card so as to initialize the TCG-Opal protocol stack based on the data in the target solid state disk.
In this embodiment, when the RAID card is powered on again, the TCG-Opal protocol stack data in the main solid state disk is checked by a CRC (Cyclic Redundancy Check), that is, whether the TCG-Opal protocol stack data in the main solid state disk is in error is checked, where the data error includes data loss and/or data error.
And if the verification is passed, namely the data of the TCG-Opal protocol stack in the main solid state disk has no error, loading the data in the main solid state disk into a system of the RAID card for initializing the TCG-Opal protocol stack based on the data in the main solid state disk. It should be noted that, after the RAID card is powered off, the data loaded by the system of the RAID card is not stored, and therefore, when the RAID card is powered on again and the data of the TCG-Opal protocol stack in the main solid state disk passes the verification, the data in the main solid state disk is loaded into the system of the RAID card, so that the TCG-Opal protocol stack completes initialization based on the data in the main solid state disk.
If the verification fails, namely data in the TCG-Opal protocol stack in the main solid state disk is wrong, selecting any solid state disk from the rest solid state disks which are in communication connection with the RAID card as a target solid state disk, reading data in the target solid state disk and loading the data into a system of the RAID card so as to initialize the TCG-Opal protocol stack based on the data in the target solid state disk.
Further, in an embodiment, the TCG-Opal-based RAID card management method includes:
and when the TCG-Opal protocol stack data is updated, updating each solid state disk based on the updated TCG-Opal protocol stack data.
In this embodiment, when the TCG-Opal protocol stack data is updated, each solid state disk establishing communication connection with the RAID card is updated based on the updated TCG-Opal protocol stack data, that is, the updated TCG-Opal protocol stack data is refreshed into each solid state disk.
