Flavors and performance classes

Currently, we offer six different performance classes.

If your performance class is too small, you need to clone your instance to a new one with a bigger performance class.

Description	ID	Max. IOPS	Max. throughput (MB/s)
Performance class 2	premium-perf2-stackit	1000	100
Performance class 4	premium-perf4-stackit	2000	150
Performance class 6	premium-perf6-stackit	5000	200
Performance class 8	premium-perf8-stackit	10000	250
Performance class 10	premium-perf10-stackit	15000	300
Performance class 12	premium-perf12-stackit	20000	350

Currently, we offer three types of instances. For each type there is a different set of flavors available.

Notes

• CPU and RAM is always per node.
• The system uses up to 15 connections for internal essential processes such as backup, monitoring, etc. These connections will be counted towards the max_connections limit.
