Abstract

The present disclosure provides a server system including a rack, a rack management controller, host devices, storage devices and two signal switches. The rack management controller generates a controlling signal. The host devices are located in the rack. The storage devices are electrically connected to the host devices respectively, are disposed in the rack and located under the host devices. The two signal switches are electrically connected to the host devices and the rack management controller respectively, each of the signal switches is electrically connected to the storage devices, and the two signal switches are disposed in the rack and located above the host devices. Each of the host devices receives the control signal through the two signal switches, so as to match one of the storage devices, such that each of the host devices performs the access and process operation for the data of the matched storage device thereof.

First claim

What is claimed is:

1. A server system, comprising:
a rack;
a rack management controller, generating a controlling signal;
a plurality of host devices, located in the rack;
a plurality of storage devices, electrically connected to the host devices respectively, the plurality of storage devices disposed in the rack and located under the host devices; and
two signal switches, electrically connected to the plurality of host devices and the rack management controller respectively, each of the signal switches electrically connected to the plurality of storage devices, and the two signal switches disposed in the rack and located above the host devices;
wherein each of the host devices receives the control signal through the two signal switches and matches with one of the plurality of storage devices, each of the host devices performs the access operation and process operation for the data of the matched storage device thereof; and
wherein each of the two signal switches comprises a temperature register, the rack management controller is electrically connected to the temperature register, so as to receive the chassis temperature information from the temperature register and generate a fan speed adjustment signal according to the chassis temperature information, and the fan speed adjustment signal is transmitted to a fan of the server system through the two signal switches for adjusting the speed of the fan.

2. The server system according to claim 1 , wherein the rack management controller receives a working mode adjustment instruction, and generates a working mode adjustment signal to the two signal switches according to the working mode adjustment instruction, each of the two signal switches changes the working mode setting data according to the adjustment signal.

3. The server system according to claim 2 , wherein each of the two signal switches comprises an electrically erasable programmable read only memory, and the working mode setting data is stored in the electrically erasable programmable read only memory.

4. The server system according to claim 1 , wherein the rack management controller receives an updating instruction and updating software of the two signal switches according to the updating instruction.

5. The server system according to claim 1 , wherein the rack management controller detects working states of the two signal switches, when the one of the two signal switches is in an offline state, the host devices and the storage devices matched with the signal switch of offline state are reallocated to the signal switch of online state through the rack management controller for re-matching with the signal switch of online state, such that the reallocated host devices and storage devices resume the normal working.

6. The server system according to claim 1 , wherein each of the plurality of storage devices is a SAS JBOD storage device.

7. The server system according to claim 1 , wherein each of the plurality of host devices comprises a host and a host bus adaptor, the host is electrically connected to the storage device and the two signal switches through the host bus adaptor.

8. The server system according to claim 1 , wherein the two signal switches are SAS switches.

9. The server system according to claim 1 , wherein the two signal switches are connected to the plurality of host devices and the plurality of storage devices through SCSI.
