Disks in a Redis cluster
Only local disks can be used in Redis Managed Database clusters.
The local disk is connected directly to the compute server through the PCIe interface via NVMe protocol. Therefore, the local disk can only be created with a Managed Database cluster.
The local disk has no network latency, so it is suitable for tasks that are sensitive to read and write speeds.
To see the performance and throughput of the disks in the different configuration lines, see the Performance and Throughput table. For a list of available configurations, see Versions and Configurations.
Local disk features
- SSD NVMe disk;
- The disk subsystem is configured in RAID 1 for the Dedicated line and RAID 10 for the other lines;
- a cloud database can only have one local disk;
- cannot be disconnected from the cloud database and connected to another database;
- you can't maximize only the local disk, you can only change the node configuration;
- is deleted with all data when the node is deleted.
