Embodiment Construction

[0012] Please refer to figure 1 A server 100 according to an embodiment of the present invention includes a casing 10 , a motherboard 20 accommodated in the casing 10 , a power supply 25 , a hard disk unit 30 , an adapter card 70 and a SAS card 40 . In this embodiment, the riser card 70 has a PCIEx16 golden finger 73 and a PCIEx16 connector 72 , and the SAS card 40 is a SAS card with a PCIEx16 golden finger 42 .

[0013] The hard disk unit 30 includes a bracket 32 ​​and a plurality of hard disks 31 accommodated in the bracket 32 ​​. The bracket 32 ​​is fixed on the front portion of the housing 10 , and has an opening 33 facing the front side of the housing 10 . The opening 33 allows the user to insert the hard disk 31 into the bracket 32 ​​from the front of the server 100 or extract the hard disk 31 from the bracket 32 ​​. The hard disk 31 is a SATA (Serial Advanced Technology Attachment, Serial Advanced Technology Attachment) hard disk or a SAS (Serial Attached SCSI) hard d...

Abstract

A mainboard comprises a detecting and switching circuit, SATA (Serial Advanced Technology Attachment) connectors and a PCIEx16 (Peripheral Component Interconnect Express) connector, wherein the detecting and switching circuit is connected with the SATA connectors and the PCIEx16 connector, the PCIEx16 connector is also connected with an SAS (Serial Attached Small Computer System Interface) card, and the detecting and switching circuit correspondingly controls the connection between the detecting and switching circuit and the PCIEx16 connector by judging the signal received by the detecting and switching circuit, and is disconnected from the PCIEx16 connector when receiving an SATA signal, so that the mainboard can communicate with an SATA hard disk through the detecting and switching circuit and the SATA connector; and when receiving an SAS signal, the detecting and switching circuit is connected with the PCIEx16 connector, so that the mainboard can communicate with SAS hard disks through the SATA connectors, the detecting and switching circuit, the PCIEx16 connector and the SAS card. A server solves the problem that the heat dissipation and assembly of the server are inconvenient due to excessive used SAS cables when being connected with the SAS hard disks. The invention also provides the server adopting the mainboard.

Description

technical field [0001] The invention relates to a motherboard, in particular to a motherboard capable of supporting different types of hard disks and a server using the motherboard. Background technique [0002] Most of the servers now use SAS (Serial Attached SCSI) hard disks as an optional or expanded configuration. However, if servers that currently support SATA (Serial Advanced Technology Attachment) hard disks want to support SAS hard disks, they need to insert SAS cards and connect them through cables. Only SAS hard drives and SAS cards can use SAS hard drives. However, the SAS cable is a relatively thick cable. When the SAS card is far away from the SAS hard disk, the cable connecting the SAS hard disk and the SAS card will take up a lot of space. Too many cables bring great inconvenience to server heat dissipation and assembly. Contents of the invention [0003] In view of this, it is necessary to provide a motherboard that can support different types of hard dis...
