Embodiment 1
[0075] In this embodiment, the functional modules connected to the processing module through a unified interface include at least one HCC, at least one DCC, and at least one CACHE. Under this combination, the function type of the processing node is (HCC+DCC+CACHE) type. The DCC in this embodiment adopts the structure with a DCC processor shown in FIG. 8 .
[0076] Still referring to FIG. 5 , the processing node in this embodiment includes a processor, a bridge slice, a SWITCH, at least one HCC, at least one CACHE, and at least one DCC. The dotted line in Fig. 5 schematically shows the data request and the transmission direction of the data in the processing node. As shown in Figure 5, the processor determines that the function type of the current processing node is (HCC+DCC+CACHE) type according to the functional modules connected to the bridge chip, and after receiving the data request, the processor executes (HCC+DCC+CACHE) The storage control operation corresponding to th...
Embodiment 2
[0093] In this embodiment, the functional modules connected to the processing module through a unified interface include at least one HCC. Under this combination, the function type of the processing node is the HCC type.
[0094] FIG. 10 is a schematic structural diagram of a processing node applied to a storage control system in Embodiment 2 of the present invention. The dotted line in Fig. 10 schematically shows the data request and the transmission direction of the data in the processing node. As shown in FIG. 10 , the processing node includes a processor, a bridge chip, a SWITCH and at least one HCC. The processor determines that the function type of the current processing node is the HCC type according to the functional modules connected to the bridge chip, and after receiving the data request, the processor executes the storage control operation corresponding to the received data request under the HCC type.
[0095] Specifically, the processor receives the data request...
Embodiment 3
[0102] In this embodiment, the functional modules connected to the processing module through a unified interface include at least one DCC. Under this combination, the function type of the processing node is DCC type.
[0103] FIG. 11 is a schematic structural diagram of a processing node applied to a storage control system in Embodiment 3 of the present invention. The dotted line in Fig. 11 schematically shows the data request and the transmission direction of the data in the processing node. As shown in FIG. 11 , the processing node includes a processor, a bridge chip, a SWITCH and at least one DCC. The processor determines that the function type of the current processing node is the DCC type according to the functional modules connected to the bridge chip, and after receiving the data request, the processor executes the storage control operation corresponding to the received data request under the DCC type.
[0104] Specifically, the processor receives data requests from o...
