I have seen people using multiple nodes on the same physical/virtual machine, I wanted to ask if there is an advantage to this. Logically, the disk space will be used for 2 copies also if the disk (or the RAID array dies) your data is toast, and your storage will be halved, but is there a significant advantage to having this config? Do the read/writes perform significantly better?
I have a cluster environment on 2 physical machines that I an trying to setup, what I am essentially looking for is fast writes and fast reads through Kibana searches and dashboards. Whats the optimal config on this?
I have 2 machines of 8C/64GB/4.8TB SSD machine which is dedicated to ELK. We also have about 3 billion total transactions that around 30 to 50 users can be querying.
