Chapter 2. LokiStack deployment size specifications
Reference specifications for LokiStack deployment sizes, including resource requirements and performance characteristics for each size tier.
2.1. LokiStack deployment size specifications
Loki sizing follows the 1x.<size> format to specify deployment capacity and performance.
Sizing for Loki follows the format of 1x.<size> where the value 1x is number of instances and <size> specifies performance capabilities.
Starting in logging 6.6, the 1x.extra-small and 1x.small deployment sizes use 3 Loki ingesters instead of 2. This increases the total disk requests for these sizes compared to earlier versions.
The 1x.pico configuration defines a single Loki deployment with minimal resource and limit requirements, offering high availability (HA) support for all Loki components. This configuration is suited for deployments that do not require a single replication factor or auto-compaction.
Disk requests are similar across size configurations, allowing customers to test different sizes to determine the best fit for their deployment needs.
It is not possible to change the number 1x for the deployment size.
