Abstract: The present application relates to a storage device operation control method, a storage device, and a management node. The method includes: receiving at least one request sent by at least one management node; and when one of the at least one request is a permission application request, determining, according to a current permission status, whether to assign operation permission to a management node that sends the permission application request; or when one of the at least one request is an operation request, determining, according to a current permission status, whether a management node that sends the operation request has operation permission, and performing an operation according to the operation request when the management node that sends the operation request has the operation permission. This avoids a conflict caused by simultaneously performing an operation on a storage device by multiple management nodes, and prevents successive serial operations from being interrupted.

Abstract: A method, an apparatus, and a communication node for suppressing output noises of peripheral component interconnect express (PCIe) devices in optical fiber communication is provided. The communication node includes a PCIe chip and a detection and control circuit connected to a transmitting end of the PCIe chip. The PCIe chip transmits an electrical signal by a transmitter of a first lane. The detection and control circuit detects a differential-mode voltage of the electrical signal. If the differential-mode voltage is lower than a first threshold, the detection and control circuit controls an optical module connected to the PCIe chip not to transmit an optical signal through the first lane of the optical module. When a PCIe system includes the communication node, output noises of the transmitter is suppressed, and a normal optical fiber communication link is ensured.

Abstract: A control device for a non-volatile memory express (NVMe) over fabric architecture is provided. The control device comprises a network adapter and a processor coupled to the network adapter by a bus. Data is transmitted between the control device and a storage device in the NVMe over fabric architecture. The processor is configured to obtain an available storage space of the storage device, determine whether a storage space required by a first data to be transmitted according to a first data read/write command is equal to or less than the available storage space, and send the first data read/write command to the storage device if the storage space required by the first data is equal or less than to the available storage space and suspend sending of the first data read/write command if the storage space occupied by the first data is greater than the available storage space.
