Description

A hard disk backplane capable of multiplexing SAS and SATA signals

technical field

The utility model relates to computer components, in particular to a hard disk backboard capable of multiplexing SAS and SATA signals.

Background technique

In the server system, the SAS signal of the Raid card is generally used. Some server systems also use the SATA signal of the PCH chip. When the server system supports the SAS function of the Raid card and the SATA function of the PCH chip at the same time, it is often necessary to connect a SAS backplane to the SAS signal of the Raid card, and another SATA hard disk backplane to connect to the SATA signal of the PCH.

Raid is to combine multiple independent physical hard disks in different ways to form a logical hard disk, which provides higher performance and data redundancy technology than a single hard disk. Raid cards are generally divided into hard Raid cards and soft Raid cards. The Raid function is realized by hardware. The independent Raid card and the Raid chip integrated on the motherboard are both hard Raid. The Raid card that uses software and uses the CPU refers to the use of the CPU to complete the common calculations of Raid. Software Raid occupies a lot of CPU resources, and most server equipment is hardware Raid.

PCH (Platform Controller Hub) is an integrated south bridge of Intel Corporation. It replaces the previous ICH10 on mainstream mobile and desktop Intel Core i7 computers. PCH is directly connected to Nehalemel P55. The P55 chip supports Intel's LGA 1156 Socket (CPU socket 1156 pin) and Core i5 processors.

Contents of the invention

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the hard disk backplane capable of multiplexing SAS and SATA signals described in the utility model will be further described in detail below in conjunction with specific embodiments.

The utility model proposes a hard disk backplane that can reuse SAS and SATA signals. The master-slave interface of the SAS connector is used in the hard disk backplane, and simultaneously supports the SAS signal of the Raid card and the SATA signal of the PCH; the master interface of the SAS connector Connect to the SATA signal of the PCH, and connect the slave interface of the SAS connector to the SAS signal of the Raid card. Like this, through the hard disk backplane described in the utility model, can realize the same interface of the same hard disk backplane, can plug in SAS hard disk to use the SAS function of Raid card, or plug in SATA hard disk to use the SATA function of PCH chip.

Example:

The hard disk backplane that can multiplex SAS and SATA signals described in this embodiment has an overall structure of a rectangular PCB card, and a SAS connector is arranged on the PCB card, and the SAS connector is provided with a main interface, Other interfaces such as slave interface and POWER; Simultaneously this hard disk backplane is connected with PCH chip and Raid card through SAS connector, and the main interface of described SAS connector connects the SATA signal of PCH chip, and the slave interface of described SAS connector connects Raid card. The SAS signal of the card; as shown in Figure 1.

The hard disk backplane that can multiplex SAS and SATA signals described in this embodiment can be plugged with a SAS hard disk through the SAS connector. When a SAS hard disk is plugged in, the SAS signal of the SAS hard disk passes through the slave interface of the SAS connector Can be connected to the SAS signal of the Raid card; at the same time, the SATA hard disk can be inserted through the SAS connector, and when the SATA hard disk is inserted, the SATA signal of the SATA hard disk can be connected to the PCH chip through the main interface of the SAS connector on the SATA signal.

In addition, through the hard disk backplane described in this embodiment, when using a SAS hard disk, the SATA function of the PCH chip can be disabled in the BIOS, which can prevent SATA signals from interfering with the SAS hard disk. Like this, adopt the hard disk backboard described in this embodiment, realized through the same interface of a hard disk backplane, support the SAS signal of Raid card and the SATA signal of PCH chip simultaneously, make the function of hard disk backplane expand, increase hard disk The versatility of the backplane further reduces product costs.
