apparatus embodiments one
This apparatus embodiments one provides a kind of memory disc, and its composition structural representation as shown in Figure 1, comprises physical interface 202, communication link administration module 204, storage medium administration module 206, storage medium 208.
Physical interface 202, for being connected with access interface, determines the type of access interface, arranges the stitch signal definition of described physical interface according to the type of access interface.
Physical interface 202 is as memory disc 200 interface mutual with the access interface of other equipment, access interface comprises server HBA, exchange interface, power board interface etc., for sending data and other the information of memory disc 200 reading to access interface, such as, handshaking information etc. in agreement setting up procedure, also for receiving the information that access interface sends.
After physical interface 202 determines the type of access interface, the stitch signal definition of physical interface is set according to the type of access interface, the clock frequency of the stitch of such as physical interface, voltage etc.Physical interface 202 can store the part of the stitch signal definition of physical interface corresponding to the type of various access interface, such as physical interface 202 confirms that access interface is after SAS interface, confirm the stitch signal definition adopting SAS interface, call SAS interface corresponding about stitch signal definition, the clock frequency of the stitch of physical interface is set, voltage etc., make physical interface in electrical equipment aspect can with access interface cooperating.The corresponding relation of the interface that the type of common access interface and physical interface 202 adopt also comprises: the type of access interface is SATA interface, and physical interface 202 adopts SATA interface; The type of access interface is NVME interface, and physical interface 202 adopts peripheral assembly interconnected (English full name: PeripheralComponentInterconnectExpress, English abbreviation: PCIE) interface fast; The type of access interface is IP interface, and physical interface adopts ether (English full name: Ethernet) interface.
Optionally, physical interface 202 determines voltage or the frequency of the signal that the access interface that the type of access interface can be received by physical interface 202 sends, and determines the type of access interface.Because dissimilar access interface supports dissimilar agreement, if access interface in precedent is SAS interface, then adopt SCSI (English full name: SmallComputerSystemInterface, English abbreviation SCSI) agreement, and if SATA interface, then can adopt Advanced Technology Attachment (English full name: AdvancedTechnologyAttachment, English abbreviation: ATA) agreement, and the voltage of the signal sent under different agreement support has different from frequency, therefore physical interface 202 can determine the type of access interface accordingly.
Optionally, as shown in Figure 2, memory disc 200 can also comprise interface type memory module 210, for the type of memory access interface.Physical interface 202 determines that the type of access interface can obtain the type of access interface from interface type memory module 210.Interface type memory module 210 can store the type information of current accessed interface, and physical interface 202 can the type of direct therefrom read access interface.
Optionally, memory disc 200 can also comprise interface type memory module 210, interface type memory module 210 does not prestore the type of access interface, the voltage of the signal that physical interface 202 sends according to access interface or frequency, after determining the type of access interface, by the type of access interface stored in interface type memory module 210.Make memory disc 200 can obtain the type of access interface from interface type memory module 210 in ensuing action, can also make memory disc 200 after replacing access interface or access equipment, the type of the access interface of memory disc 200 before new access equipment can obtain.
Communication link administration module 204, arranges communication link for the type according to access interface.Communication link administration module 204 is connected with physical interface 202, and the method that communication link administration module 204 obtains the type of access interface has two kinds, one, and physical interface 202, after determining the type of access interface, directly informs communication link administration module 204; Its two, when having interface type memory module 210 in memory disc 200, communication link administration module 204 can obtain the type of access interface from interface type memory module 210.
The link control message of communication link corresponding to various access interface is stored, such as the frequency of operation of the communication link that different access interface is corresponding, coding and decoding ability, power management etc. in communication link administration module 204.
The agreement that the type of various access interface is corresponding is stored in communication link administration module 204, such as, the corresponding SCSI agreement of SAS interface, SATA interface corresponding A TA agreement, the corresponding NVME agreement of NVME interface, corresponding key assignments (English full name: KeyValue, English abbreviation: the KV) agreement of IP interface.Concrete, the KV agreement that IP interface is corresponding can be that can also be based on ROCE (English full name: RDMAOverConvergedEthernet), can also be based on the IWARP agreement based on ICP/IP protocol directly based on ICP/IP protocol.
Optionally, communication link administration module 204 arranges communication link according to the type of access interface, comprising: the link arranging communication link according to the type of access interface controls, and link controls the frequency of operation, the power configuration that comprise link; Obtain agreement corresponding to the type of described access interface according to the type of access interface, perform the agreement that the type of access interface is corresponding.Communication link administration module 204 obtains corresponding link control message according to the type of access interface, complete after the arranging of the physical layer of communication link, perform the agreement that access interface is corresponding, realize the setting of the agreement of communication link, comprise the program of initiated access equipment end, service data service processes and task management process etc.
Such as, it is after SAS interface that communication link administration module 204 obtains access interface, although the SCSI agreement that SAS interface is corresponding, but SCSI agreement has multiple version, the SCSI agreement storing the version that this memory disc uses also is needed, with the SCSI agreement making communication link administration module 204 perform corresponding version in communication link administration module 204.
Optionally, communication link administration module 204 sends and arranges success message to access interface after performing agreement corresponding to the type of access interface, arranges success message instruction memory disc and completes setting.After communication link administration module 204 pairs of communication links complete arranging of physical layer and agreement, whole memory disc 200 is actual enters the state that can work, but now access equipment also and do not know the situation of memory disc 200, therefore communication link administration module 204 after accomplishing the setting up, sent by physical interface 202 and arrange success message, notice access equipment can normally access memory disc 200.
Storage medium administration module 206, for managed storage medium 208, to make access interface by communication link access storage media 208.Storage medium administration module 206 managed storage medium 208, memory disc 200 after accomplishing the setting up, the Physical layer of the communication link of memory disc 208 and agreement are all with ready, and the request of access of access equipment, by after physical interface 202, can pass through communication link access storage media 208.
