PORT INDICATING CIRCUIT FOR HARD DISK BACKPLANE AND SERVER SYSTEM

摘要

A port indicating circuit for a hard disk backplane of a server system includes a port circuit and an indicating circuit. The port circuit includes a control microchip and at least one selecting microchip. The hard disk backplane includes a number of ports. The server system includes a number of servers connected to some of the ports. The selecting microchip is connected to the control microchip and the remaining ports. If the control microchip detects that one or more standby servers form part of the server system, the control microchip selects the one or more standby server to connect to the remaining ports. If the control microchip does not detect that the one or more standby servers form part of the server system, the control microchip selects the servers to connect to the remaining ports. The indicating circuit indicates operating status of hard disks on the hard disk backplane.

1. A port indicating circuit for a hard disk backplane of a server system, the hard disk backplane comprising a plurality of ports, the server system comprising a plurality of servers connected to a first group of the ports, the port indicating circuit comprising a port circuit and an indicating circuit, wherein the port circuit comprises:
a control microchip configured for detecting whether one or more standby servers electronically form part of the server system, the control microchip comprising at least one detecting terminal electrically connected to the one or more standby servers when the one or more standby servers form part of the server system; and at least one selecting microchip connected to the control microchip and a second group of the ports, wherein when the control microchip detects one or more standby servers that forms part of the server system, the control microchip selects the one or more standby servers to connect to the second group of the ports via the least one selecting microchip; wherein when the control microchip does not detect the one or more standby servers to form part of the server system, the control microchip selects the plurality of servers to connect to the second group of the ports via the least one selecting microchip; and wherein the indicating circuit are configured to indicate operation status of hard disks on the hard disk backplane according to signals output from the plurality of servers.
