I have few questions about the results of the calculation.
Master Nodes = 1 qty
Worker Node = 4 qty
and lower worker node's configuration
Are these requirements only for MAS to be working + OCP base requirements?
But OCP requeres at least 3 master and 3 worker nodes, isn't it?
Is it nodes with dedicated roles or can be master + worker?
3. Storage data is only for MAS or DB2 is also included here ?
first of all make sure that You are using the latest calculator (v8_10 for now). It is available in Seismic.Secondly, it seems that You've set 'Enforce 3 Master + 2 Worker Nodes' to False - if You set it to True You will get 3 masters in calculations (each being 4x16). You can change the workers hardware spec in the bottom of the calculator.
OCP does require 3 masters (apart from SNO) and at least 2 workers - it does not have to be exactly 3 workers, can be 2 or 10 as well. Only workers are running user workloads, so total sum in calculator gives estimate for both MAS (in workers) and OCP (in masters and workers).
As for storage - there is a separate column for DB2 storage, but it is very hard to estimate that, cause it it highly dependent on how MAS is going to be used.
There is also one thing missing in the calculator: ephemeral storage size. The more apps You are going to use (or Manage add-ons) the more ephemeral storage You need.
Yes, i used old version of calculator that is only one aviable on techXchange.
The calculator link has been updated to reflect the latest. You should see 8.10 version when you download from here: https://www.ibm.com/docs/en/mas-cd/continuous-delivery?topic=premises-requirements-capacity-planning
