Redis host classes

The host class determines the computing power allocated for each host in a cluster. When you change the class for a cluster, all existing hosts change to match it.

The host class also determines which disk types are available:

• hm1: network-ssd, local-ssd
• hm2, hm3: network-ssd, local-ssd, and network-ssd-nonreplicated
• b2, b3: network-ssd

The storage space available to the host should be at least twice as large as the selected memory size. For more information on Managed Service for Redis technical and organizational limitations, see Quotas and limits.

Configuration types:

• burstable: Configurations with a guaranteed vCPU share under 100%. Those host classes are intended for test loads. We do not recommend using them for production solutions.

  A cluster with this configuration type can only contain one host per cluster or shard.

• high-memory: Standard configurations for Redis.

  A cluster with this configuration type may contain one or more hosts (within the current quota) per cluster or shard. The minimum number of hosts in a cluster depends on the selected disk type.
