Configure Swarm Cluster Services (SCS)

Follow the below steps to configure Swarm Cluster Services (SCS):

1. Storage nodes use these credentials.

2. Gateways use these credentials when PAM authentication is selected.

3. Telemetry only uses the password, with a built-in admin username. You can adjust administrators post-installation via the Grafana UI.
   

   

4. Click Next.

5. Select the network interface from the drop-down list for the internal interface. This interface is used to PXEboot the storage nodes.

   

   1. Enter the IP address and network mask for the internal interface.

6. Click Next.

7. Provide a Swarm Site Id. This is a unique Id given to the cluster. Site Id must be a human-oriented name used to identify a cluster among different clusters available within the organization.
   

   

8. Swarm generates a unique cluster name using the Site Id. Customers are allowed to modify it and can provide any unique name for the Swarm storage cluster.

9. Click Next.

10. Configure DHCP service running on the SCS node:
    

    

    1. DHCP Gateway IP and domain name are picked automatically based on previous steps where DHCP gateway IP is non-editable.

    2. Details of the already added DNS and NTP servers are picked, however, a customer can add more DNS/NTP servers if required.

    3. DHCP Reserve Lower & Upper - Number of IP addresses to reserve for lower and upper network subnet range out of the range defined.
       Example: In case there are 235 IP addresses, out of that first 10 IP addresses are reserved for the lower range and the last 20 for the upper range.

       

    4. DHCP Transient % (Removed in SCI 2.7.0) - The percentage of remaining IP addresses (which are not reserved in the lower and upper range) allocated for the transient pool.
       Example: 50% of the remaining range is reserved for pooling and the rest is reserved for storage.

    5. DHCP Reserve Default Time - DHCP lease expiration time in seconds if the client has not requested any time.

    6. DHCP Lease Maximum Time - Maximum lease time in seconds allocated by the server when the client requests the time.

11. Click Next.

12. Upload the License file using Add button. Once the license file is uploaded or the URL to the license file is provided, click Add.
    

    

    
    The uploaded file is added with the below details:
    

    

13. Click Install to proceed with the added license file. It displays a confirmation wizard where click Yes to initiate the installation process. Swarm SCS product itself comes with a default license, therefore, this step is optional.
    

    

14. Wait for the installation to complete. Click Show Details to understand the installation progress or errors. If not, click Next to proceed.
