We have cluster in private cloud with node configuration (8vCPU, 64GB RAM, 1TB disk SSD/VSAN) in 13 data nodes + 3 master nodes.  
Due to better utilization of our cloud resources, our IT team asked me to reconfigure nodes to smaller instances. So I am thinking of ½ = 4vCPU, 32GB RAM, 0,5TB disk SSD/VSAN and double number of instance 26 data nodes + 3 master nodes  
Can I expect some negative/positive performance impact for 64G -\> 32G and doubling number of VMs?
