Hostname Resolution
The host names of all active DNIF components should resolve with each other.
You can use a hosts file or a domain name server to resolve hostnames and IP addresses on a DNIF deployment.
Clock sync with NTP
If you have an NTP Server configured already on your network, then configure its services accordingly on all DNIF active components.
Storage Mounts
DNIF is installed within /DNIF folder, to mount a SSD storage separately, then you have to create a /DNIF directory and mount your SSD storage on it.
