Rack server system and operation method applicable thereto
First Claim
1. A method for controlling a battery backup unit (BBU) configured to hold at least one BBU sub-system, each BBU sub-system including at least one battery module, the method comprising:
- receiving a new BBU sub-system in the BBU, the new BBU sub-system including at least one undercharged battery module;
charging, after the receiving, the at least the one undercharged battery module;
determining that the charging is complete, the determining being performed by any one of the BBU, the new BBU sub-system, at least one of the battery modules in the new BBU sub-system; and
updating, in response to the determining, the status information in a memory,wherein while the at least one BBU sub-system in the BBU is unfunctional and the input power is outside of normal operating tolerances, another one of a plurality of BBU sub-systems in the BBU provides power to a server coupled to the BBU, and the server records relevant information such that the server adjusts its own loading according to the relevant information; and
while a self-discharging test is performed on the at least one battery module of each BBU sub-system and the input power is outside of normal operating tolerances, other battery modules of the plurality of BBU sub-systems provide power to the server.

Abstract
A rack server system and an operating method applicable thereto are provided. The rack server system includes a battery backup unit (BBU) and at least one server. The operating method includes: communicating the server and the BBU with each other; the BBU providing a status information and a previous self-discharging test information to the server for the server to judge a status of the BBU; and providing power from the BBU to the server and adjusting a loading of the server according to the status information of the BBU when an input power is interrupted.

4. A rack server system, comprising:
-
a battery backup unit (BBU); and at least one server coupled to the BBU; wherein, the BBU provides status information and previous self-discharging test information to the server for the server to judge a status of the BBU; and when an input power is outside of normal operating tolerances, the BBU provides power to the server, and the server adjusts its own loading according to the status information of the BBU; wherein after a new BBU sub-system is loaded into the BBU, at least any one of the BBU, the new BBU sub-system, or battery modules within the BBU sub-system determines whether charging is completed, and wherein after charging is judged to be completed, the BBU stores the status information; wherein the server receives and records the status information of the new BBU sub-system; if one of a plurality of BBU sub-systems in the BBU is unloaded or broken, another one of the plurality of BBU sub-systems in the BBU provides power to the server when the input power is outside of normal operating tolerances; while a self-discharging test is performed on one of the BBU modules of the one of the plurality of BBU sub-systems, other BBU modules of the one of the plurality of BBU sub-systems provide power to the server if the input power is outside of normal operating tolerances; and while the one of the plurality of BBU sub-systems is unloaded or broken, the server records relevant information, such that the server adjusts its own loading according to the relevant information if the input power is outside of normal operating tolerances. - View Dependent Claims (5, 6, 7, 8)
