Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this hair
It is bright to be described in detail.Following disclosure provides many different embodiments or example is used to realize different knots of the invention
Structure.In order to simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relationship between various embodiments and/or setting is discussed.It should be noted that illustrated component is not necessarily to scale in the accompanying drawings
It draws.Present invention omits the descriptions to known assemblies and treatment technology and process to avoid the present invention is unnecessarily limiting.
As shown in Fig. 2, using scheme proposed by the present invention, if necessary to support 4 NVME hard disks, 4 SAS, SATA disks,
1 9460-16I that arranges in pairs or groups only is needed in system.NVME hard disk can share the same uplink and connect with SAS, SATA hard disc
Device, the link of SAS, SATA link and NVME need that identical link can be shared.It is connect with uplink board, existing technical solution
SAS, SATA and NVME need different CABLE to establish the link, in the present embodiment, SAS hard disk, SATA hard disc and NVME hard disk
It is established the link using identical CABLE.Using original design scheme, two kinds of Managed Solutions are needed support above backboard,
SAS, SATA hard disc need to be managed by SGPIO, and NVME hard disk needs to be managed by VPP, and the present invention only needs to lead to
It crosses UBM different type hard disk can be realized managing hard disk and be total to link.Existing technology is compared with scheme proposed by the present invention, no
Material Cost is increased only, and it is also higher to research and develop cost.
As shown in figure 3, the comparison that PIN U.3 and U.2 is defined can see, 4 road PCIE in terms of pin assignment U.2,
SAS0, SAS1 are and SAS0/PCIE0, SAS1/PCIE1, SAS2/PCIE2, SAS3/PCIE3 U.3 using different PIN
Share identical PIN.U.2 compatible NVME and when SAS, SATA simultaneously, to have independent lane, PCB trace,
Connector, Cables, and when U.3 need to be compatible with NVME and SAS, SATA simultaneously, lane, PCB Trace,
Connector, Cables can be shared.This U.3 to realize that TRI-MOD is simpler, more cost-effective.
As shown in figure 4, a kind of backboard for supporting more hard disks simultaneously, comprising: connect with uplink board and more mouthfuls of hard disks upper
Trip link actuator HFC, the downlink interconnection interface DFC connecting with the storage medium of U.3 interface pass through UBM backboard Managed Solution management
Master chip PSOC and the GPIO expander of different type hard disk；The PCIEX4 signal end and 100M of upper trip link actuator HFC
REFCLK+/- signal end is connect with downlink interconnection interface DFC.CH_DET# signal end, the PERST# signal of upper trip link actuator HFC
End, 2WRST# signal end, I2C signal end are connect with master chip PSOC；The CH_DET# signal end of downlink interconnection interface DFC,
PERST# signal end, 2WRST# signal end, I2C signal end are connect with GPIO expander, the I2C signal end of master chip PSOC,
