    Study Notes

    Host Commissioning

    • To add a host to an existing or new workload domain, complete a checklist to ensure the host meets the required criteria.
    • The host needs a pre-imaged version of ESXi and a resolved DNS.
    • Network pools must be created and configured before commissioning the host.
    • Storage type cannot be changed after host commissioning.
    • Hosts can be commissioned individually or in bulk.
    • NTP and Syslog must be enabled.

    Host Validation

    • Retrieve and compare host certificates with VCF.
    • Confirm host certificates by checking the status.
    • Remove validation-failed hosts.
    • Perform a full host validation.

    Bulk Commissioning Hosts

    • A maximum of 32 hosts can be commissioned at a time using a JSON template.
    • Hosts must include the FQDN, username, password, storage type, and network pool name in the JSON template.

    Network Pool

    • Network pools must be created before commissioning hosts.
    • VCF assigns IP addresses for specific services.
    • Network types supported include vMotion, VSAN, NFS and iSCSI.
    • raw ISCSI is not a valid storage option.
    • iSCSI is for VVOL configuration.

    Network Pool Settings

    • Provide VLAN IDs and subnets for each network type.
    • Specify IP address ranges and gateways.
    • MTU settings should also be configured.

    Network Pool Creation Steps

    • Use the Create Network Pool wizard to define the network pool.
    • Specify the network pool name
    • Select the required network types.

    Network Pools - Important Considerations

    • Network pools cannot be deleted if there are IP addresses assigned to them.
    • Changing the name of an existing network pool isn't recommended.
    • Adding IP address ranges is typically done when the pool is being created.

    Additional Concerns

    • SDDC Manager manages host commissioning tasks for workload domains. Hosts can be assigned or unassigned to different domains.
    • The maximum number of hosts for a cluster is 64.
    • Hosts must use the same storage type and network pool within a cluster.
    • Hosts must meet a checklist of criteria.
    • vSAN requires a minimum of 3 hosts for single redundancy and 5 for double redundancy.
    • In vSphere, the best practice for vSAN is to use homogeneous hardware across all hosts, enabling more stable behavior.
