Detailed ways

In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

It should be noted that the Ethernet interface hard disk in this application document is a hard disk device with network function, which has an Ethernet interface and can be directly connected to the network through the Ethernet interface of the network switch.

The method for managing the hard disk capacity of the Ethernet interface provided by the embodiment of the present invention can be applied to the scenario shown in Figure 1. As shown in Figure 1, the switch provided by the embodiment of the present invention is connected to multiple hosts, that is, has multiple tenants , the switch can connect multiple hard disks with Ethernet interfaces. After the switch, hard disks with Ethernet interfaces, and hosts are networked, the switch can communicate with each host, and can also interact with each hard disk with Ethernet interfaces. The network administrator can allocate the capacity of the hard disks to the connected hosts through the switch. After receiving the hard disk configuration information from the network administrator, the switch sends capacity allocation commands to each Ethernet interface hard disk. The capacity allocation command includes the host IP address and the hard disk storage space allocated to the host IP address. After receiving the capacity allocation command, the Ethernet interface hard disk records the IP address of each host and the hard disk storage space assigned to the host IP address, and when the switch sends a request message to obtain the relationship between the host IP address and the hard disk storage space The corresponding relationship between the IP address and the hard disk storage space allocated to the host IP address is returned to the switch. When the switch subsequently receives the write operation command sent by the host, it can judge whether the write operation address in the write operation command is included in the hard disk storage space allocated to the IP address according to the corresponding relationship, and if so, forward the write operation command to The hard disk storage space corresponds to the Ethernet interface hard disk, and the available hard disk storage space corresponding to the IP address is adjusted according to the storage space occupied by the content to be written in the write operation command. In this way, the switch can manage the capacity of the hard disk with the Ethernet interface, which simplifies the networking and capacity management of the hard disk with the Ethernet interface.

Fig. 2 is a flow chart of a method for managing the hard disk capacity of an Ethernet interface provided by an embodiment of the present invention. The executive body of this embodiment is a switch, the switch is connected to multiple Ethernet interface hard disks, and the switch is connected to multiple hosts. This example describes in detail how the switch manages the capacity of hard disks with multiple Ethernet interfaces. As shown in the figure, the switch can perform the following steps:

Step 201, according to the storage space allocation information of the Ethernet interface hard disk in the received hard disk configuration information, send a capacity allocation command to each Ethernet interface hard disk, and the capacity allocation command includes the host IP address and the IP address assigned to the host IP address. Hard disk storage space.

Wherein, after the switch, the hard disk with the Ethernet interface, and the host are connected to the network, the switch can first send a query command to each hard disk with the Ethernet interface to obtain the hard disk information of each hard disk with the Ethernet interface. The format of the command sent by the switch to the hard disk on the Ethernet interface is as follows:

Among them, Ethernet Header is the Ethernet header of the command;

IP header is the IP header of the command;

TCP header is the TCP header of the command;

The operation code is used to identify the type of command. For example, the operation code is 1, which means that the command is used to identify the hard disk with the Ethernet interface. After the hard disk receives the command with the operation code 1, it can return to the sender whether it is an Ethernet interface. Hard disk information, the operation code is 2 means that the command is used to obtain the hard disk capacity of the Ethernet interface, and the operation code is 3 means that the command is used to configure the host IP address and the hard disk capacity of the Ethernet interface or a key-value pair (Key- Value, KV), after the hard disk receives the command whose operation code is 3, the corresponding relationship can be set according to the "KEY or initial LBA" field in the command, and the operation code is 4, which means that the command is used To obtain the corresponding relationship between the host IP address and the hard disk capacity of the Ethernet interface or the key-value pair, the operation code is 5, indicating that the command is used to read the Ethernet interface in the form of Logical Block Address (LBA) Hard disk data command, the operation code is 6 means that the command is to write the hard disk data of the Ethernet interface in LBA mode, the operation code is 7 means that the command is to read the Ethernet interface hard disk in KV mode, and the operation code is 8 means that the The command is the command to write the Ethernet interface hard disk in KV mode;

Key or starting address LBA, which is used to identify the address of the switch to access the hard disk of the Ethernet interface or the key value of the content to be accessed;

Data length, used to identify the size of the content to be read and written by the switch,

Data content, used to identify the content to be written by the switch;

Ethernet trailer, which is the filled field of the command.

After the switch and the Ethernet interface hard disk are networked, the switch first broadcasts and sends a command to identify the Ethernet interface hard disk with an operation code of 1. After the hard disk on the Ethernet interface returns the identification information, which includes the manufacturer of the hard disk on the Ethernet interface, the capacity of the hard disk on the Ethernet interface, and the operation mode of the hard disk on the Ethernet interface, etc., the switch continues to send the acquisition Ethernet interface with the operation code 2. The hard disk capacity command of the interface, the hard disk of the Ethernet interface returns the available capacity of the hard disk to the switch.

After the switch receives the available capacity returned by the hard disk of the Ethernet interface, it records the available capacity information.

The administrator can allocate capacity to the hosts connected to the switch according to the available capacity information of each Ethernet interface hard disk recorded by the switch. After the switch receives the hard disk configuration information from the network administrator, it sends a capacity allocation command to each Ethernet interface hard disk. The operation code of the capacity allocation command is 3, which is used to configure the relationship between the host IP address and the Ethernet interface hard disk capacity or KV. The corresponding relationship among them, the capacity allocation command includes the IP address of the host and the hard disk storage space allocated to the IP address of the host. Wherein, the hard disk storage space includes information such as an address and a size of the hard disk storage space.

For example, for the IP1 address of the host 1, the network administrator can allocate the storage space of the Ethernet hard disk 1 whose address is 0x00000000 to 0x01000000 for the IP1 address, and then the allocation command sent to the host 1 can include the allocation information, so as to configure the host The corresponding relationship between the IP1 address of 1 and the storage space of Ethernet hard disk 1 whose address is 0x00000000 to 0x01000000.

Step 202, receiving and storing the corresponding relationship between the host IP address sent by each Ethernet interface hard disk and the hard disk storage space allocated to the host IP address.

After the Ethernet interface hard disk receives the capacity allocation command, if it is determined that the host IP address can be successfully allocated the storage space required in the capacity allocation command, then the host IP address is allocated the storage space required in the capacity allocation command, And record the host IP address and the hard disk storage space allocated to the host IP address.

If the Ethernet interface hard disk receiving the capacity allocation command finds that the storage space required in the capacity allocation command has been occupied or cannot be allocated for the host IP address due to other reasons, an allocation operation will be returned For a failed response message, the switch that receives the response message can re-allocate storage space for the host IP address.

Preferably, when the switch sends an operation code of 4 to the Ethernet interface hard disk to obtain the corresponding relationship between the host IP address and the Ethernet interface hard disk capacity or KV, the IP interface will record each host IP address in the system record area. The corresponding relationship with the hard disk storage space allocated to the IP address of the host is returned to the switch.

Step 203, when receiving the write operation command issued by the host to write data to the Ethernet interface hard disk, judge whether the write operation address in the write operation command is included in the hard disk storage space corresponding to the IP address, if yes, The write operation command is then forwarded to the hard disk with the Ethernet interface corresponding to the hard disk storage space, and the size of the available hard disk storage space corresponding to the IP address is adjusted.

If the write operation address in the operation command is not included in the hard disk storage space allocated to the IP address, then return the indication information that cannot be written.

When the switch receives the write operation command issued by the host to write data to the Ethernet interface hard disk, the switch can first determine the Ethernet interface hard disk that the host wants to access according to the content of the "Key or initial LBA" field in the write operation command According to the IP address in the IP header information, determine the host IP address, and then determine whether the host IP address can be written or not according to the corresponding relationship between the locally recorded host IP address and the hard disk storage space allocated to the host IP address. The write operation address carried in the operation command, that is, according to the Key or LBA carried in the write operation command and the length of the data to determine whether the address for data writing is included in the hard disk storage space corresponding to the IP address of the host, if it is included, it means that the write If the content in the operation command can be written into the corresponding write operation address, the write operation command is forwarded to the hard disk with the Ethernet interface, and if not, the instruction information that cannot be written is returned to the host.

Preferably, after the write operation command is sent to the Ethernet interface hard disk, according to the data length in the write operation command, it is determined that the host IP address uses the size of the Ethernet interface hard disk after this write operation, and then according to the write The storage space occupied by the content to be written in the operation command adjusts the available hard disk storage space corresponding to the IP address.

Preferably, the method provided by the embodiment of the present invention further includes: when receiving a read operation command issued by the host to read data from the hard disk of the Ethernet interface, if the Key parameter value included in the read operation command is not an existing value, then Returns the indication information indicating that the Key parameter value does not exist in the hard disk of the Ethernet interface.

When the switch receives the read operation command issued by the host to read data from the hard disk of the Ethernet interface, the switch can first determine whether the content to be accessed by the host exists according to the value of the Key parameter in the read operation command, and if so, send the data to the Ethernet interface. The interface hard disk forwards the read operation command; otherwise, an indication message indicating that there is no content corresponding to the Key parameter value in the Ethernet interface hard disk is returned.

Wherein, if the hard disk storage space corresponding to the IP address of the host computer in the write operation command is not recorded in the switch, after receiving the write operation command issued by the host computer to write the Ethernet interface hard disk, after judging the write operation command in the write operation command, Whether the operation address is included in the hard disk storage space assigned to the IP address, it is also necessary to obtain the locally stored hard disk storage space assigned to the IP address according to the IP address included in the write operation command, that is, to The hard disk on the Ethernet interface sends a command whose operation code is 4 to obtain the corresponding relationship between the IP address of the host and the capacity or KV of the hard disk on the Ethernet interface.

Therefore, through the technical solution provided by the embodiment of the present invention, the capacity management of the Ethernet interface hard disk by the switch is realized, and the networking and capacity management of the Ethernet interface hard disk are simplified.
