Abstract
A cooling system provides redundant fault-tolerant cooling to electrical devices in an electrical apparatus and comprises a plurality N+1 individual cooling fans, N cooling fans being required to provide cooling of the devices and further comprises monitor logic for monitoring the status of the plurality of cooling fans and for issuing a non-critical warning to the apparatus in the event of failure of one of the cooling fans, the logic being further operable, in the event of a failure in the logic, to issue a non-critical warning to the apparatus.
Claims21
A cooling system for providing redundant cooling to electrical devices in an electrical apparatus, the cooling system comprising:
- a plurality N+1 individual cooling means, N cooling means being required to provide cooling of said devices;
- and
- monitor logic for monitoring the status of said plurality of cooling means, said logic being operable, in the event of a failure in said logic, to issue a non-critical warning to said electrical apparatus to thereby allow continued operation of said electrical apparatus.
A data storage system comprising:
- a plurality of disk data storage devices;
- a plurality N+1 fan means for providing cooling in said system, N fan means being required to provide cooling of said data storage devices;
- and
- fan monitor means for monitoring the status of said fan means, operable in the event of a failure in said monitor means to issue a non-critical failure warning to said system.
