Description
Technical field
The present invention relates to server hard disc technical fields, specifically provide a kind of storage of compatible SAS/SATA/NVME hard disks
Card.
Background technology
Hard disk is the important hardware device in server, have in server many hard disks needs be managed and agreement on
Conversion, storage card is the adapter being connected between mainboard and backboard, is to realize management and the general increase to hard disk
Performance.With the appearance and use of NVME hard disks, backboard end has used a SFF-8639 interface, can support simultaneously three kinds it is hard
Disk, i.e. SAS hard disks, SATA hard disc and NVME hard disks currently need storage card also while supporting this configuration.
Existing NVME hard disks are all directly on mainboard, by the way that in PCIE link connections to CPU, storage card can only
It supports SAS hard disks and SATA hard disc, is managed, with the appearance and use of NVMe hard disks, due to agreement, control signal etc.
Difference, current storage card can not be compatible with such hard disk.Three kinds of SAS hard disks, SATA hard disc and NVME hard disks hard disks cannot be met
It is articulated under the same storage card simultaneously, using upper underaction, is unfavorable for managing.
Invention content
The technical assignment of the present invention is in view of the above problems, to provide a kind of structure design advantages of simple, can be certainly
Identification SAS hard disks, SATA hard disc and NVME hard disks are adapted to, the compatibility SAS/ of unified management and lighting control is carried out to hard disk
The storage card of SATA/NVME hard disks.
To achieve the above object, the present invention provides following technical solutions：
A kind of storage card of compatible SAS/SATA/NVME hard disks, including backplane interface, main control chip, electric pressure converter one, voltage
Converter two, CLOCK BUFFER and SWITCH, backplane interface are provided with for being connected with backboard on the main control chip
GPIO, electric pressure converter one and GPIO, backplane interface are separately connected, and electric pressure converter two and GPIO, backplane interface are separately connected,
The SWITCH is separately connected with backplane interface, electric pressure converter two, CLOCK BUFFER, and SWITCH is connected with main control chip
It connects, CLOCK BUFFER are connected with main control chip.
The backplane interface of one x8 can support the NVME hard disks of 8 SAS/SATA hard disks or 2 x4.It is passed in data
It may be implemented to be compatible on defeated signal wire, be realized with a link.Due to the point modulating signal of tri- kinds of hard disks of SAS/SATA/NVME
And control signal is different, is while supporting tri- kinds of hard disks of SAS/SATA/NVME, handles sideband signals, and due to line
The pin limited amounts of cable and interface need the signal in the presence of multiplexing.
SAS hard disks and SATA hard disc manage the state of hard disk using the signal transmitted by GPIO, and NVME hard disks are then adopted
With new lighting scheme-VPP agreements, a kind of IIC signals, each data represents different states.CLOCK BUFFER are generated
NVME starts the signal of need of work, passes to backplane interface by cable, and then pass to backboard end.SWITCH is in CLOCK
Switch between two signals that BUFFER and GPIO is generated, and then realizes the control to SAS hard disks, SATA hard disc and NVME.
The backboard information that electric pressure converter one is transmitted according to backplane interface is gone back to judge being SAS hard disks or SATA hard disc
It is NVME, and then GPIO CLOCK BUFFER are walked in the selection signal selection of SWITCH chips, and signal is transmitted by cable
The lighting of hard disk is controlled to backboard.
Storage card of the present invention is arranged on mainboard PCIE slots.
Preferably, the backplane interface uses SFF8643 interfaces, i.e. miniSAS HD.
Preferably, the electric pressure converter one is connected by BP_TYPE, CTR_TYPE with backplane interface, it is used for back
Pass backboard state.
The BP_TYPE signals for detecting backboard show to be NVME hard disks at this time if it is 1, and the selection of SWITCH chips is believed
CLOCK BUFFER are walked in number selection, and GPIO sends VPP protocol signals.Show to be that SAS hard disks or SATA are hard at this time if it is 0
Two signals of SGPIO are walked in disk, the selection signal selection of SWITCH chips, and GPIO sends the another two signal of SGPIO, passes through line
Cable is transmitted to the lighting of backboard control hard disk.
Preferably, the electric pressure converter two is separately connected by SGPIO and SWITCH, backplane interface.
Preferably, the CLOCK BUFFER are connected by PCIE with SWITCH.
Preferably, the CLOCK BUFFER are used to generate the clock differential signals needed for NVME.
Preferably, the clock differential signals are 100M.
Compared with prior art, the storage card of compatibility SAS/SATA/NVME hard disks of the invention has with following prominent
Beneficial effect：The storage card of the compatible SAS/SATA/NVME hard disks is different by identifying the control signal of backboard, carry out agreement and
The switching of sideband signals, can self-adapting estimation SAS/SATA hard disks and NVME hard disks, realize and different types of hard disk carried out
Unified management and lighting control, have good application value.
Description of the drawings
Fig. 1 is the schematic diagram of the storage card of compatible SAS/SATA/NVME hard disks of the present invention.
Specific implementation mode
Below in conjunction with drawings and examples, the storage card of the compatibility SAS/SATA/NVME hard disks of the present invention is made into one
Step is described in detail.
