Host configurations

The host configuration determines the computing power allocated for each host in the cluster. When you change the host configuration 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 max amount of data is 75% of the available memory. For example, for a host with 8 GB RAM, maxmemory is set to 6 GB.

The hard disk space available to the host should be at least two times more than the selected memory size. For technical and organizational limitations of Managed Service for Redis, see Quotas and limits.

Available host configurations

Configuration types:

  • burstable: Configurations with a guaranteed vCPU share below 100%. Those host classes are intended for test loads. We don't recommend using them for production solutions.
  • high-memory: Standard configurations for Redis.
