Valkey™ 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 Yandex Managed Service for Valkey™ 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 Valkey™.

  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.
