Prerequisites

Prerequisites for Configuring Connector 3

  • Make sure you allow access to necessary endpoints based on the region of your Cisco Spaces account. Refer to the following table for the endpoints that must be enabled:

    Table 1. Enable Endpoints
    Cisco Spaces Account Endpoint to be Enabled
    https://dnaspaces.io https://connector.dnaspaces.io
    https://dnaspaces.eu https://connector.dnaspaces.eu
    https://ciscospaces.sg https://connector.ciscospaces.sg
    https://ciscospaces.io https://connect.ciscospaces.io
    https://ciscospaces.eu https://connect.ciscospaces.eu
    https://ciscospaces.sg https://connect.ciscospaces.sg

  • Allow firewall to access these IP’s addresses based on the respective regions.

  • The Cisco Spaces: Connector works as expected when two tokens are generated and configured on two separate instances. However, if an additional token is generated and configured on a third connector instance, a certificate will not be issued, causing the hotspot to fail.

    Ensure that no more than two tokens are generated for each Connector and configured on the Cisco Spaces: Connector instances to prevent hotspot failures.

  • Connector needs to be able to reach a Domain Name System (DNS) server. If you set up an explicit proxy, ensure that Connector 3 maintains the ability to communicate through this proxy.

  • VMware ESXi 7.0, 8.0 or 9.0.1.0.

  • VMware vCenter 7.0 or 8.0

  • Virtual machine size: Advanced 2 (Recommended)

  • Minimum bandwidth required: 4 Mbps


    Note

    Make sure that the x86-64-v2 CPU is available for Enterprise Linux 9. Also, ensure that the x86-64-v2 CPU supports the following flags: SSE3, SSE4_1, SSE4_2, and SSSE3.

Recommended Deployment Architecture - Advanced2

This is the recommended deployment architecture for IoT and location combined use case:

  • Virtual machine size (vCPU): 8

  • Memory: 16 GB

  • Hard Disk: 120 GB


Note

We recommend that you use specifications of 8 vCPUs and 16 GB of RAM for optimal performance and efficiency.
