+= Loki deployment sizing
+
+Sizing for Loki follows the format of `1x.<size>` where the value `1x` is number of instances and `<size>` specifies performance capabilities.
+
+For logging 6.1+, `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.
+
+
+[IMPORTANT]
+====
+It is not possible to change the number `1x` for the deployment size.
