NOTE: If you install QoreStor with the -f option, or answer yes to the prompt regarding firewall changes, the QoreStor installer will ensure these ports are open. |
Port configuration
The ports below need to be available for the QoreStor service:
| Component/Function | Ports required |
|---|---|
| UI / Cloud Tier |
|
| OST / RDA When using Rapid NFS or Rapid CIFS, the ports for both RDA and NFS or RDA and CIFS, respectively, are required.If Secure Connect is used with Rapid CIFS, then the Secure Connect port is also required.1 |
|
| NFS1 |
|
| Replication |
|
| CIFS1 |
|
| Object (S3) |
|
| NDMP |
|
| RDA-NDMP |
|
|
iSCSI |
|
|
Secure Connect If Secure Connect is used for all RDA and OST clients, then only the Secure Connect port is needed for RDA and OST. 2 |
