    Study Notes

    Workload Domain Prep - Host Commissioning

    • Hosts are added to the VMware Cloud Foundation inventory during commissioning.
    • Hosts must meet specific criteria for vSAN/VSAN ESA/vSAN Max workload domains, as outlined in the VMware Hardware Compatibility Guide.
    • Hosts need a standard switch with two minimum 10 Gbps NICs, along with correct drivers and firmware versions.
    • DNS server configuration (forward and reverse lookup, FQDN) must be present. Hostname should match FQDN.
    • Management IP must be configured on the first NIC port.
    • Standard switch uplinks must be configured using traditional numbering and increasing sequentially.
    • Host hardware health must be error-free.
    • All disk partitions (HDD/SSD) must be deleted.
    • Required network pools (vMotion, VSAN, NFS, VMFS, FC, vVol, ISCSI, VMOTION) should exist and be associated, respectively, before commissioning.
    • Hosts with DPUs require SR-IOV enabled in BIOS and vSphere Client.
    • SDDC manager creates distributed switches, do not create them prior to this time.

    Bulk Commissioning

    • Maximum of 32 hosts can be commissioned at a time.
    • A JSON template file can be used for this process.
    • Host validation, including retrieving fingerprints and comparing them with VCF, are crucial steps (must be validated).
    • Hosts with fingerprints that cannot be validated are removed.
    • An error ("esx-7.vcf.sddc.local: FQDN to IP address look-up failed") during commissioning may require individual host re-validation.

    Network Pools

    • VCF assigns network (IP addressing) to hosts for vMotion, VSAN, NFS, and iSCSI.
    • Raw iSCSI is not a storage option; iSCSI network must be for VVOL configuration.
    • Network pools must exist prior to host commissioning.
    • Ensure required network pool is created and available.
    • Host network type (e.g. VSAN) must be associated with the correct corresponding network pool.

    Network Pool Settings

    • Network pool configuration requires VLAN ID for each network type.
    • Subnet for each network type, IP address range (inclusive), MTU, gateway settings.
    • A subnet must be configured for ISCSI. VSAN is handled differently.

    Host Validation

    • Host fingerprints (certificates) must be retrieved and compared with VCF.
    • All host fingerprints should be verified.
    • Hosts with un-validated fingerprints must be removed.

    Network Pools for VCF

    • Network pools are preconfigured, but are used for storage and network access for hosts.
    • Some network types require subnets, such as iSCSI.

    Network Pool Creation

    • Create pools using the Create Network Pool wizard.
    • Input network pool name.
    • Select network types.
    • The network pools cannot be deleted once created if they have associated IP addresses.
    • The management (mgmt) domain network pool always consumes IP addresses

    Network Pool Details

    • The name of a network pool cannot be changed after it has been created.

    Process for Network Pool

    • Network settings should be configured during administration.
