Abstract

The embodiment of the invention relates to storage equipment and an energy-saving method thereof. The storage equipment comprises a storage controller and at least two buckled cards, wherein the two buckled cards comprise a main working buckled card and a non-main working buckled card; each buckled card comprises at least two ports, and the ports and at least one host machine establish at least one logical link. The storage controller comprises a monitoring module and a power-off management module, wherein the monitoring module is used for monitoring transmission indexes of the logical links; and the power-off management module is used for controlling the non-main working buckled card in which the ports for establishing the logical links are located to be power-off according to a threshold value of the transmission index of the configured logical link and the transmission index of the logical link monitored by the monitoring module. When the storage equipment is in a non-busy state, the embodiment of the invention reduces the quantity of hardware in a working state under the condition of a certain quantity of the hardware in the whole storage equipment to save the energy consumption in the storage equipment.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a storage device and an energy-saving method thereof. Background technique [0002] With the development of storage technology, customers have put forward higher requirements for the function, performance and cost of storage devices. Various storage device manufacturers have developed storage devices with more cores and larger caches to meet customers' requirements for storage devices. In order to meet the requirements of function and performance, storage devices with more front-end subcards are developed to save the switch connecting the storage device and the host, thereby saving costs. The subcard is a small board with a chip capable of implementing a Small Computer System Interface (Small Computer System Interface, referred to as SCSI) protocol and providing a physical interface connected to the host. The small board is connected to the controller on the storage device throu...
