Storage address, the 2nd NVMe storage regions are determined according to the storage address.Here storage address can be directly institute
State the physical address or logical address of the 2nd NVMe storage regions.
Certainly, perhaps the read requests do not carry storage address in certain embodiments, and only carrying needs to read
The Data Labels of data, described control unit 120, using the Data Labels as inquiry foundation in the storage mediums such as internal memory, is looked into
The storage address of the 2nd NVMe storage regions of storage corresponding data is ask, so that it is determined that going out the 2nd NVMe storage regions.
In a word, described control unit 120 is also responsible for parsing the read requests, it is determined that being read from which NVMe unit 110
Data, so which position of the NVMe units 110 reads data.
In the above-described embodiments, it is single that what the NVMe units 110 can be as shown in Figure 2 is connected to the control by bus
In member 120, it can also be connected respectively to as shown in Figure 2 in described control unit 120.
In certain embodiments, described control unit 120, in addition to detection module, the detection module are used to detect each
The running status of the NVMe units 110, when discovery NVMe units 110 occur recovering different in the irrecoverable abnormal or specified time
Chang Shi, the data of the NVMe units 110 are transferred on other NVMe units 110, and corresponding modification data storage record, with
Just reading and/or rewriting of the server to corresponding data.In the present embodiment, the detection module, can timing or not timing
The prearranged signals that heartbeat signal of storage chip transmission of NVMe units 110 etc. represents its normal work is received, when corresponding
When not received on the time, it is believed that exception occur in corresponding NVMe units 110, note abnormalities and can be carried out Data Migration,
It is of course also possible to determine a need for further detection, determine the need for carrying out Data Migration by further detecting.
