Disks
Disks
Only local disks can be used in Redis cloud database clusters.
The local disk is connected directly to the Compute Server via the PCIe interface using the NVMe protocol. Therefore, a local disk can only be created with cloud database cluster.
The local disk has no network latency, so it is suitable for tasks that are sensitive to read and write speeds.
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 enlarge only the local disk, you can only reconfigure nodes;
- is deleted with all data when the node is deleted.
Performance and throughput
Local disk performance and throughput in fixed Standard and HighFreq configurations is dependent on disk size.
To see a list of available configurations, see the instructions Versions and configurations.
