I am quite new to OPNFV and am trying to understand the OPNFV hardware architecture and its requirement.
OPNFV architecture requires 3 nodes (Compute, storage and network node). Pharos compliant lab structure requires 5 nodes (1 Jump server, 3 Controller nodes and 2/n compute nodes) according to Pharos hardware spec.
Comparing these 2 architecture i have the following queries. It will be very helpful if someone could help me in understanding these.
Requirement of 3 controller nodes ? Does one of the controller nodes in pharos architecture act as a storage node and the other controller nodes has different functions?
In which component (JumpServer/Control nodes/Compute nodes) in pharos architecture, does the VNF run (With respect to processing and storage)?
From the hardware architecture guide of pharos compliant lab structure, it looks we require disk space of 2*1 TB + 1 * 100 GB SSD and 32GB RAM. Is it a minimum requirement or can we still have a lower disk space and memory for basic lab setup ?
Please advice on the minimum disk space and RAM requirement for each components of Pharos (Jump Server, Control nodes and compute nodes).
Does management functions like VNF manager and VIM runs (Processing wise) on Jump server?
Thanks in advance!!!!
