Method used to guarantee data reliability of Kafka

2

After a Kafka Broker receives a message, it persistently stores the message on a disk. In addition, each partition of a topic has multiple replicas stored on different Broker nodes. If one node is faulty, the replicas on other nodes can be used.

Method used to ensure high data reliability on OceanStor 9000
The unique InfoProtector function of OceanStor 9000 ensures high data reliability. OceanStor 9000 ensures that data remains accessible when physical devices are faulty, and automatically recovers data on faulty physical devices. Data protection levels can be flexibly configured by setting different redundant ratios to obtain optimal data reliability and storage space utilization.

Method used to plan reliability of the RAID group
You can plan the RAID group as follows: After a RAID group is created in the storage system, data is stored in the member disks of the RAID group. The mirroring and parity check functions of a RAID group provide reliable data recovery mechanisms if the member disks in a RAID group fail.
