The present invention is directed to the weak point that prior art exists, propose the storage unit that the many main frames of a kind of Based PC I-E are shared.
The storage unit that the many main frames of a kind of Based PC I-E of the present invention are shared, the technical scheme solving the problems of the technologies described above employing is as follows: the storage unit that the many main frames of this Based PC I-E are shared, Based PC I-E, and merge in conjunction with storage host interface protocol FC/IP application model, its project organization mainly comprises: connect unit outside (1) host side PCI-E, (2) store end main frame shared cell, (3) host side access control is isolated; Outreach unit by host side PCI-E, the signal of PCI-E slot is reduced and amplifies, and output interface is redefined, be converted into high speed QSFP transmission definition; By storage host end shared cell, the transmission definition transmitted by QSFP, carries out circuit recovery, reverts to Standard PC I-E agreement, and be connected to SAS disk management controller; Host side access control isolation refers to, carries out SAS controller virtual at storage end, by virtual SAS address, by virtual for SAS control chip be multiple virtual SAS controller, and virtual SAS address and Hostname to be bound.
Preferably, on the HBA card that host side is external, signalization reduction and amplification chip, carry out the signal of PCI-E to reduce and amplify.
Preferably, host side outlet is set to QSFP interface, PCI-E line sequence is adjusted, and carries out sequence definition by the definition of QSFP interface.
Preferably, store end respective hosts end and QSFP interface is set equally, store end simultaneously and be provided with PCI-E SWITCH, QSFP line sequence is oppositely transformed according to host side sequence definition, be converted into Standard PC I-E agreement, and connect storage end SAS disk management controller.
The beneficial effect that the storage unit that the many main frames of a kind of Based PC I-E of the present invention are shared compared with prior art has is: instant invention overcomes the weak point that traditional server stores connected mode, the feature that Based PC I-E communicates, and merge in conjunction with application models such as storage host interface protocol FC/IP, the transmission method of Common advantages with two-forty, low delay is proposed; By the access of software control to physics SAS controller, to be conducted interviews sequence by software, solve the problem of access conflict under shared model; Reduce equipment cost simultaneously, and improve storage transmission speed.

Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the storage unit that the many main frames of a kind of Based PC I-E of the present invention are shared is further described.
The storage unit that the many main frames of a kind of Based PC I-E of the present invention are shared, a kind of new design Storage framework is proposed, the feature that Based PC I-E communicates, and merge in conjunction with application models such as storage host interface protocol FC/IP, design the transmission method of Common advantages with two-forty, low delay.The project organization of storage unit of the present invention mainly comprises: connect unit outside (1) host side PCI-E, and (2) store end main frame shared cell, and (3) host side access control is isolated.
Storage unit of the present invention, outreaches unit by host side PCI-E, reduces and amplifies, and redefine output interface the signal of PCI-E slot, is converted into high speed QSFP transmission definition, is suitable for transmitting at a distance.
Storage host end shared cell, to the transmission definition transmitted by QSFP, is carried out circuit recovery, reverts to Standard PC I-E agreement, and be connected to SAS disk management controller.
Host side access control is isolated, and carries out SAS controller virtual at storage end, by the virtual SAS address of software definition, by virtual for SAS control chip be multiple, and by virtual SAS address and Hostname binding, reach access and isolate object.
Embodiment:
The storage unit that the many main frames of a kind of Based PC I-E described in the present embodiment are shared, its structure mainly comprises: connect unit outside (1) host side PCI-E, and (2) store end main frame shared cell, and (3) host side access control is isolated.
Unit is connected outside described host side PCI-E, as shown in Figure 2:
The design of tradition extrapolation HBA card, its core is the protocol translation of chip collocation FW, the present embodiment abandoning tradition pattern, on the HBA card that host side is external, signalization reduction and amplification chip, do not do any protocol translation, simple carries out the signal of PCI-E to reduce and amplify; In order to long-distance transmissions preferably, host side outlet arranges QSFP interface, PCI-E line sequence is adjusted, and carries out sequence definition by the definition of QSFP interface, to reach the object of suitable transmission.
Described storage end main frame shared cell, as shown in Figure 3:
Store end design respective hosts end, QSFP interface is set equally, stores end simultaneously and be provided with PCI-E SWITCH, the line sequence of QSFP is oppositely transformed according to host side sequence definition, be converted into Standard PC I-E agreement, and connect storage end SAS disk management controller (controller).
Described host side access control isolation, as shown in Figure 4:
Under current design architecture, SAS disk management controller can be seen by all main frames, so need to carry out access control step by step, reaches SAN design standards.The present embodiment sets up software virtual layer on bottom physical equipment, arranged, simulate the virtual SAS controller of sufficient amount at software virtual layer by virtual SAS address; When being stored in mapping, virtual SAS address and respective hosts title are bound, reach the object of access isolation; Upper-level virtual SAS controller, by the access of software control to physics SAS controller, to be conducted interviews sequence by software, under solving shared model, and the problem of access conflict.
