1. Determine the following:

   1. What subnet Platform manages

   2. Which network interface on the server is connected to that subnet

2. Use the following Linux command to find the interface name:

   Code Block
   language bash
   ifconfig

3. Document any IP addresses not to be leased by Platform (reserved range).
   For example, for HSRP ranges: x.x.x.1-x.x.x.3 or x.x.x.252-x.x.x.254

4. Determine the number of nodes (chassis) anticipated for this cluster and select a subnet range for their the IP addresses (dynamic range).
   For a cluster of 10 chassis, the subnet range may be: x.x.x.240 - x.x.x.249

5. Download the latest bundle from the Downloads section on the DataCore Support Portal: Swarm-VERSION-DATE.zip

6. Transfer the Swarm components (ZIP files) to the Platform server:

   • Platform Server (non-OVA install) — caringo-platform-VERSION.zip

   • Service Proxy (To host the Swarm Storage UI if Content Gateway is not available) — serviceproxy-VERSION.zip

   • Swarm Storage — storage-VERSION.zip

...

1. Import the OVA file into your ESXi/vSphere environment. During the import process, add any network interfaces and configure as necessary.

   Info
   title Private subnet
   To support a private subnet for Storage and Elasticsearch nodes, the Platform server needs both public and private network interfaces (like the dual-network CSN). Important: With nodes on a private subnet, you must complete Deploying a Proxy to provide access to the health report server and other network resources, such as replication feed targets, NTP servers, and DNS. Without an interface into that private network, the Swarm UI cannot be accessed by an external browser.

2. Once the OVA is imported and booted for the first time, configure the networking as necessary within the OS. You can ssh into the Platform server using the following username/password: caringoadmin/caringo

3. Once the networking configuration completes and validates, run the following command where STORAGE_NIC_IP is the static IP of the NIC connected to the storage network:

   Code Block
   language bash
   sudo /opt/reinit.sh -i STORAGE_NIC_IP

   Info
   title Offline mode
   If the server cannot access the Internet, use Offline mode by adding the -o flag when running reinit.sh.

   Info
   title Important
   If you enter the wrong IP address in the above command, the bootstrap command will be caught waiting and not return. See "Bootstrap Command Hangs" in Platform Troubleshooting.

4. When the reinit.sh script has finished, reboot the Platform Server.

...

1. Unless you are installing in offline mode, verify that there is at least 300 MB space available to run the bootstrap command, which downloads updates from the Internet.

2. Once you have the interface name, you can list all of the available CIDR (Classless Inter-Domain Routing, or supernetting) network addresses:

   Code Block
   language bash
   platform list subnets --all

3. Run the bootstrap command for the Swarm Platform environment, which includes preparing Swarm Storage for deployment to managed nodes. 

   Code Block
   language bash
   platform bootstrap -i PATH_TO_STORAGE_ZIP -v VERSION -t DHCP_SUBNET -a STARTING_IP_RANGE -z ENDING_IP_RANGE

   • Path — The Swarm Storage ZIP file for this command is located in the \Storage folder within the Swarm-VERSION-DATE.zip download. The filename has this form: storage-VERSION-x86_64.zip. You may change the version of Swarm Storage at any point after the bootstrap completes.

   • Version — Version of Swarm Storage, in the form #.#.#.

   • DHCP Subnet — The DHCP subnet CIDR calculated above. The platform list subnets command provides the proper format:

     Example

     Code Block
     language bash
     $ platform list subnets --all Subnet: 10.1.1.0/24 Subnet: 172.17.0.0/16 Subnet: 192.168.68.0/24

     If the storage subnet is 192.168.68.x, then use 192.168.68.0/24

   • Dynamic Range — Use the dynamic range IPs you found in step 4 of the Installation Checklist, above.

     Info
     title Caution
     The Dynamic Range specified in the bootstrap command must contain at least 10 IP addresses and also cover less than 25% of the total address space for the subnet. Taking up more than 25% of the addresses could result in too few IP addresses to boot Storage chassis. You can use a --force flag to force use of a range that violates these rules, but do so with caution.

     Info
     title Caution
     The DHCP range is necessarily contiguous based on the STARTING_IP_RANGE and ENDING_IP_RANGE. The IP ranges allocated for Storage nodes can be non-contiguous by reserving IPs with the "platform add iprange" command as shown below.   Be careful not to define a DHCP range that includes your Platform server's Swarm-managed network interface.

4. If you have other IP addresses on the same network not managed by Swarm Platform, create Create a reserved IP range so that their the IP addresses cannot be allocated for Storage nodes if there are other IP addresses on the same network not managed by Swarm Platform:

   Code Block
   language bash
   platform add iprange -a STARTING_IP_RESERVED -z ENDING_IP_RESERVED

5. Before deploying Swarm, upload Upload a valid license in order for Swarm to boot successfully before deploying Swarm.

platform upload license -f PATH_TO_LICENSE_TXT
