Deploying the Velostrata Backend

The Velostrata On-Premises Backend virtual appliance connects to VM disks in your on-premises data center and streams or migrates them to GCP using Cloud Extensions.

The Velostrata Backend is distributed as an Open Virtualization Format (OVF) package.

Sizing a VM for the Velostrata Backend

The Velostrata Backend requires the following, based on the number of VMs to be migrated concurrently:

Migration Size Resources
  • <=100 concurrent migrating VMs
2 vCPU, 4GB RAM
  • >100 concurrent migrating VMs
4 vCPU, 8GB RAM

Deploying and configuring the Velostrata Backend

  1. Download the Velostrata Backend. You can verify the integrity of the files using the SHA256 checksum.
  2. Sign in to vSphere via the Flash Web Client.

  3. Right-click a parent object of one of the VMs to be migrated (such as a datacenter) and select Deploy OVF Template.

  4. Select the Velostrata OVA file.

  5. Choose the Host/ Cluster in your vSphere datacenter where you want to run the Velostrata Backend.

  6. Select a Disk Format, and click Next.

  7. Select the Network information that will host the Velostrata Backend. Click Next.

  8. Expand the Velostrata Backend Configuration section.

  9. Paste the token you copied from the Velostrata Manager on GCP into Velostrata Backend Token.

  10. Enter and confirm a Password for the admin user on the Velostrata Backend. After installation, the password should be changed by connecting to the Velostrata Backend using SSH as admin and using the passwd command.

  11. Add the Private IP address of the Velostrata Manager (for example 10.1.1.123) running on GCP.

  12. Expand the Networking Properties section. Enter the Hostname for the Virtual Appliance. Enter a static IP Address, Netmask, Default Gateway, and DNS server for the Velostrata Manager.

  13. If you want to use an HTTP proxy for metrics and log uploads to Stackdriver, fill in the HTTP Proxy parameter.

  14. If your VPN to GCP is not configured with dynamic routing, you can enter the Static network route to reach subnets on GCP. The address is in the form x.x.x.x/x y.y.y.y, where x.x.x.x/x is the GCP VPC network address in CIDR format and y.y.y.y is the VPN Gateway IP address.

  15. Click Next and review the Ready to complete page.

  16. Check Power on after deployment to power up the Velostrata backend right away.

  17. Click Finish. The Deploy OVF template task appears.

Deploying the Velostrata VMware vCenter Plugin

Once the Velostrata Backend has successfully connected and registered with the Velostrata Manager on GCP, you need to register and deploy the Velostrata VMware vCenter Web Client Plugin. This enables Velostrata management operations and monitoring in the vCenter UI.

  1. Make sure that a Velostrata vCenter Service Account (user) and Role have been created before proceeding.
  2. Sign in to your Velostrata Manager.
  3. Click the System Settings icon.
  4. If the Velostrata Backend is able to connect to the Velostrata Manager, the IP for the backend appears with a status of Registered and Connected.

  6. Enter the vCenter address or DNS name, user, password
  7. The vCenter plugin requires network connectivity to the Velostrata Manager. If this is not open by default, you can either create a direct route on your vCenter server or use a proxy. If using a proxy, add the Proxy IP and the Proxy Port.
