Why is configuring regional shared storage locations on a CIFS server using DNS Round Robin the best design choice for vDisk storage?

While DNS Round Robin itself is inexpensive to implement, it relies on having multiple CIFS servers and their storage, which might not make the overall solution the absolute least expensive compared to a single server.

DNS Round Robin provides basic load distribution but lacks true high availability or fault tolerance mechanisms; if a server fails, DNS still directs requests to it until its record expires or is manually removed, making it not inherently highly resilient.

DNS Round Robin distributes client requests across multiple servers by returning different IP addresses from a list for the same DNS query in a cyclical fashion. This method is relatively simple to configure as it primarily involves creating multiple A records for a single FQDN, thus requiring minimal setup and ongoing management compared to more complex load balancing or clustering solutions, which contributes to lower administrative overhead.

DNS Round Robin requires multiple servers to distribute load, which inherently increases the system footprint compared to a single server solution.
