Hello,

I want to know hardware (ie server) configuration for OpenNebula setup in HA. I suppose each VM will have 4vCPU, 8GB RAM and 100GB HDD.

Hello @kaushal143

[Here](http://docs.opennebula.org/5.10/deployment/cloud_design/open_cloud_architecture.html) you can find some information about recommended specs for OpenNebula frontends servers. So in HA environment the three servers should have the same specs.

Best,  
Álex.
