Server conversion system for converting PCIE interface into SATA interfaces

Abstract

The invention relates to a server conversion system for converting a PCIE interface into SATA interfaces. The server conversion system is characterized by comprising a conversion control circuit, the control circuit comprises a main control chip and a memory chip; the main control chip is connected with the memory chip, and is also connected with the SATA interfaces and the PCIE interface. One PCIE interface is converted into two SATA interfaces, digital power in design is close to a pin of the main control chip to reduce inductive reactance, the use ratio of a server can be increased through the low cost, it is achieved that the memory capacity is greatly improved, and meanwhile a simple data conversion device can be provided for design test and verification of a laboratory.

Description

technical field [0001] The invention belongs to the technical field of server storage, and in particular relates to a conversion system for converting a server PCIE interface into a SATA interface. Background technique [0002] PCI Express is a new generation of bus interface, which is a point-to-point serial device connection method. Point-to-point means that each PCI Express device has its own independent data connection, and the concurrent data transmission between each device does not affect each other. For the shared bus method of PCI in the past, only one device can communicate on the PCI bus. Once the number of devices connected to the PCI bus increases, the actual transmission rate of each device will decrease, and the performance cannot be guaranteed. PCIExpress handles communication in a point-to-point manner. Each device establishes its own transmission channel when it requests to transmit data. This channel is closed to other devices. This operation ensures the e...
