DNS-based load balance for CIFS documentation questions

Sorry for the disturbance, let me try to ask several questions regarding 'how-to giudes' in file access via CIFS topic? The goal is spread across two controllers the access of a several thousands (but less 10000) Windows-based clients to CIFS share at OceanStor or Dorado system.

1. The document 'How Can I Configure and Use DNS-based Load Balancing' (here) explains this for OceanStor 2600V3. At the Client configuration step #1 (both a and b) it's visible the particular client is configured with only single DNS IP, which refers to first logical port. In which mechanism the different DNS IP should be distributed among clients in effective way? DHCP with configuration groups? Will it be more convenient (for organization) to set both primary and secondary DNS as first and second logical adapters addresses? Will it be possible to set both addresses as single name at corporate DNS to obtain the round-robin style of connections balancing?

2. The document 'Creating a Logical Port' (here) shows the logical port creation panel (step 6) with 'Listen DNS query requests' option disabled. Should that option be set to 'enabled', if the DNS-based load balancing was configured at Step '(Optional) Configuring DNS-based Load Balancing Parameters' (here)? Does that procedure applicable not to Dorado only, but to OceanStor as well?

Thank You!

Hy @polezhaevdmi
1. You can add both IPs in the DNS entry of the client if you want, as both are referring to the same domain. And yes as the document suggests, both ips can be set to one domain name, and round-robin style balancing can be achieved. System forwards the request to the ip address with less load according to load balancing policy.
2. You should enable that option.
And same process will be followed for the OceanStor. GUI may be different, but procedure is same.

Dear polezhaevdmi,


Multiple IP addresses can be mapped to one domain name, it's possible to set both addresses as a single name at corporate DNS to obtain the round-robin style of connections balancing.  And you have many questions let me check it.

Hello, the main quastion is about MS AD. Consider two nodes installed different IP addresses. So we receive two DNS names. How to add both controllers (with its IPs) to MS AD to authorise shares access by AD?

@little_fish, @Ihteshamraza, a lot of thanks for your explanations! Now it's clear the clients distribution across subcontrollers is possible in two ways: load balancing at external DNS level, or, via DNS delegation at external level with addition of load balance at the storage level. Cheers!
