A feature of the OneFS file system is SmartConnect, which allows the workload to be dynamically reassigned to other nodes in the cluster if a node fails. SmartConnect must be configured. There is also a DNS dependency for SmartConnect to function properly. Configuration of DNS host A records and Delegation zones is necessary. Once this is done, SmartConnect assigns the workload to each node using the round-robin method. Using the FQDN that was configured previously for the SmartConnect zones is required. This section covers the completion of the SmartConnect configuration.
Go to Server Manager > Tools > DNS and configure the following:
Table 36. DNS parameters for SmartConnect
Parameter
Value
Forward Lookup Zone
dell.local
Reverse Lookup Zone
100.67.108
172.18.11
Host A record for sczoneA
sczoneA
172.18.1.160
Delegation zone for sczone1
sczone1
sczoneA.dell.local
172.18.1.160
It is important that the DNS Host A record is a unique name that does not match the name that was assigned to the SmartConnect zone within the OneFS file system. The Delegation zone, however, needs to have a name that matches the SmartConnect zone. This ensures that a connection to sczone1.dell.local references the SmartConnect Zone 1 IP of 172.18.1.160. When this IP is referenced, it will round robin through each node IP, assigning the workload to each node in turn, ensuring a balanced workload.
