Redis host classes
The host class determines the computing power and storage allocated for each host in a cluster. When you change the class for a cluster, all existing hosts change to match it.
Note
The amount of memory allocated to a host is also determined by the maxmemory
configuration parameter for Redis hosts; the maximum amount of data is 75% of the available memory. For more information, see Memory management in Managed Service for Redis.
The storage space available to the host is fixed at three times the selected memory size.
For Managed Service for Redis technical and organizational limits, see Quotas and limits in Managed Service for Redis.
Available host classes
Configuration types:
- high-memory: VMs with an increased RAM to vCPU ratio (from 4:1 to 16:1).
- standard: Standard VMs with 4:1 RAM to vCPU ratio.
- memory-optimized: VMs with an increased RAM to vCPU ratio (8:1).
