Valkey™ host classes before June 20, 2023
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.
Note
The amount of memory allocated to a host is also determined by the maxmemory configuration parameter for Valkey™ hosts; the maximum amount of data is 75% of the available memory. For more information, see Memory management.
The host class also determines which disk types are available:
- hm1:
network-ssd,local-ssd - hm2:
network-ssd,local-ssd,network-ssd-nonreplicated - hm3:
network-ssd,network-ssd-nonreplicated - b1, 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.
Available host classes
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.
