cluster but within the site) to be used for name resolution. A DNS suffix specifies a DNS domain name without the host part of
the name (for example, west.example.com rather than computer1.west.example.com).
If clients access the FluidFS cluster by name, you must add an entry in the DNS server that associates the FluidFS cluster name
to the FluidFS cluster client VIPs. If you are using multiple client VIPs, add all client VIPs to the DNS server and associate them
with the same FluidFS cluster name (known as round-robin DNS). This association enables client load balancing between client
VIPs. In addition, you must configure DNS if you are using Active Directory, and the DNS servers must be the same DNS servers
that your Active Directory domain controllers use.
