Server system and data access method using the same
First Claim
1. A server system, comprising:
- a first server, comprising;
a first host;
a first expander unit, coupled to the first host; and
a first peripheral device, coupled to the first expander unit; and
a second server, comprising;
a second host;
a second expander unit, coupled to the second host through a data bus or a peripheral component interconnect express bus; and
a second peripheral device, coupled to the second expander unit,wherein the first expander unit and the second expander unit are directly connected to each other through a serial attached small computer system interface or a peripheral component interconnect express bus,wherein when the first host and the second host function normally, the first host accesses the first peripheral device through the first expander unit and the second host accesses the second peripheral device through the second expander unit, and when the second host changes from normal function to malfunction, the first host accesses the second peripheral device through the serial attached small computer system interface or the peripheral component interconnect express bus between the first expander unit and the second expander unit.

Abstract
A server system and a data access method using the same are provided. The server system includes a first server and a second server. The first server includes a first host, a first expander unit and a first peripheral device. The first expander unit is coupled to the first host, and the first peripheral device is coupled to the first expander unit. The second server includes a second host, a second expander unit and a second peripheral device. The second expander unit is coupled to the second host, and the second peripheral device is coupled to the second expander unit. The first expander unit is connected to the second expander unit. The first host accesses the first peripheral device through the first expander unit. The first host further accesses the second peripheral device through the first expander unit and the second expander unit while the second host malfunctions.

6. A data access method, adapted for a server system, wherein the server system comprises a first server and a second server, the first server comprises a first host, a first expander unit, and a first peripheral device, and the second host comprises a second host, a second expander unit, and a second peripheral device, wherein the first expander unit and the second expander unit are directly connected to each other through a serial attached small computer system interface or a peripheral component interconnect express bus, wherein when the first host and the second host function normally, the first host accesses the first peripheral device through the first expander unit and the second host accesses the second peripheral device through the second expander unit, the data access method comprising:
-
determining whether the second host changes from normal function to malfunction; and accessing the second peripheral device through the first expander unit and the second expander unit by using the first host through the serial attached small computer system interface or the peripheral component interconnect express bus between the first expander unit and the second expander unit when the second host changes from normal function to malfunction, wherein the second expander unit is coupled to the second host through a data bus or a peripheral component interconnect express bus. - View Dependent Claims (7, 8, 9, 10, 11, 12)
