Embodiments of this application provide a load balance method and an apparatus thereof. The method may include the following steps: receiving, by a load balance node, a first service request packet from a service request end, where the first service request packet includes address information of the service request end, address information of a to-be-processed load balance instance, and a MAC address of the load balance node; determining a to-be-processed service member based on the address information of the to-be-processed load balance instance, where the to-be-processed service member is configured to process the first service request packet; and modifying the MAC address of the load balance node in the first service request packet to a MAC address of the to-be-processed service member, to obtain a second service request packet, and sending the second service request packet to a computing node to which the to-be-processed service member belongs.

Load balance method and apparatus thereof

The present disclosure discloses a method for assuring quality of service in a storage system, where a control node calculates, based on a quantity of remaining I/O requests of a target storage node in a unit time, a quantity of I/O requests required by a storage resource to reach a lower assurance limit in the unit time, and a quantity of I/O requests need to be processed by the target storage node for the storage resource in the unit time, a lower limit quantity of I/O requests that can be processed by the target storage node for the storage resource in the unit time; allocates, based on the lower limit quantity of I/O requests, a lower limit quantity of tokens of the storage resource on the target storage node in the unit time to the storage resource; and sends the lower limit quantity of tokens to the target storage node.

Method for assuring quality of service in distributed storage system, control node, and system

A storage controller includes a distribution core, a plurality of sorting cores, and a request processing core. The three types of cores are separately configured to distribute an input/output (IO) request to different sorting cores, generate a processing sorting index for each IO request, and process the IO request according to a value of the processing sorting index of each IO request to flexibly schedule the IO request received by the storage controller.

IO request processing according to processing sorting indexes

This application relates to the field of storage technologies, and discloses a storage controller. The storage controller includes a distribution core, a plurality of ranking cores, and a request processing core. The three types of cores are respectively configured to: distribute IO requests to different ranking cores, generate a processing ranking index for each IO request, and process the IO request based on a value of the processing ranking index of the IO request, to flexibly schedule an IO request received by the storage controller.
