Adding a Cluster to an SDDC

• Console
• CLI
• API

• 1. Open the navigation menu , select Hybrid, and then select VMware Solution.
  2. Click the name of the SDDC that you want to add a cluster to. If you don't see the SDDC listed, ensure that the correct compartment is selected.
  3. Click Add cluster, and provide information for the cluster:
     • Cluster name: Enter a descriptive name for the cluster. A maximum of 22 characters are allowed. Avoid entering confidential information.
     • Availability domain: Select the Availability domain in which to create the SDDC. If you have requested the Multi AD feature, you can choose to deploy dense shape ESXi hosts across multiple availability domains. Standard shape ESXi hosts can be deployed only in a single Availability domain. To ensure high availability, ESXi hosts in the SDDC are distributed across the fault domains in the Availability domain. The management subnet and VLANs for this SDDC must be in this same Availability domain.
     • ESXi hosts: Provide configuration information:
       • Host type: A multi host SDDC can have from 3 to 64 hosts. A single-host SDDC can have only one host, and has more limited functionality. See SDDCs for a detailed feature description.
       • Number of ESXi hosts: Enter the initial number of ESXi hosts to create in a multi host SDDC. Specify at least 3 hosts and at most 64 hosts.
       • Prefix for ESXi hosts: (Optional) Enter a prefix to use for the names of the ESXi hosts to help identify them. It must be from 1 to 16 characters long, must start with a letter, and can contain only alphanumeric characters and hyphens (-). Avoid entering confidential information.
         Important
         
         ESXi host names can have a maximum of 22 characters including the prefix. Host FQDNs can have a maximum of 64 characters total.
       • Capacity type: On-demand capacity provisions the compute capacity when the host is created. Capacity reservation uses capacity that's counted against a reservation. Choose a compartment and the name of a reservation. For more information, see Capacity Reservations.
         Note
         
         Capacity reservation isn't supported for an SDDC that uses many Availability domains.
       • SDDC hardware type: Select a shape to use for ESXi hosts in the SDDC. A shape is a template that decides the number of CPUs, amount of memory, and other resources allocated to a newly created instance. If you choose a shape with an AMD processor, select the number of cores. Standard shapes require block volume storage. A management datastore is automatically created for you. If you want more storage, you can create it later in this workflow. For more information, see Supported Shapes.
       • Enable shielded instance: Select this check box to enable shielded instances for all ESXi hosts created in the SDDC. You can enable this option only when you create the SDDC. You can't enable this option later, or only for specific ESXi hosts.
       • Pricing interval commitment: Select the pricing interval to apply to the ESXi hosts. For more information about available pricing intervals, see Billing Options. Choose an option, and then select Pricing interval must be confirmed to continue.
  4. Click Next to advance to the cluster's Networking page.
  5. Choose a VCN for the cluster. The VCN can be in a different compartment than the cluster and its ESXi hosts.
     If you enabled HCX, the selected VCN must have a NAT gateway attached to it.

     • If a NAT gateway already exists for the VCN, the name, compartment, and public IP address information is displayed.
     • If no NAT gateway is attached to the selected VCN, the workflow creates one for you. Enter a name and select a compartment for the NAT gateway.
  6. To have the workflow create the network resources for this cluster (recommended), click Create new subnet and VLANs, and then provide the following values. To use existing resources, skip to step .
     1. Click Create new subnet and VLANs.
     2. Enter an available CIDR block in the selected VCN for the cluster management CIDR. The workflow divides this CIDR into equal segments to use for the provisioning subnet and the required VLANs. The workflow creates 1 subnet and 7 VLANs for version 6.x and 1 subnet and 9 VLANs for version 7.x of the VMware software. If you enable HCX, one extra VLAN is created.
     3. (Optional) Click Show network details to view or edit the information for the subnet and VLANs that the workflow creates. Details include the route table and security list for the subnet, and the route table and NSG for each VLAN. To update the information for the subnet or a VLAN, click the Actions menu () on a row, and select Edit subnet or Edit VLAN.

        If you have enabled HCX, another route rule is created to allow traffic from the vSphere VLAN to the NAT gateway.

  7. To use existing network resources for this cluster, click Select existing subnet and VLANs, and then provide the following values:
     1. Choose the compartment and provisioning subnet for the cluster management network. You can't change the subnet after provisioning.

        The CIDR value shown is the private address space for the chosen subnet.

     2. Choose the compartment and VLAN for each function of the management network.

        The VLAN gateway CIDRs shown are the CIDR blocks from which to derive IP addresses for each VLAN's layer 3 traffic. These CIDR blocks also provide the private IP addresses that Oracle uses as attachment objects for public IP addresses when ESXi hosts require internet access.

        • NSX Edge Uplink 1: Uplink used for communication between the VMware SDDC and OCI.
        • NSX Edge Uplink 2: Reserved for future use to deploy public-facing applications on the VMware SDDC.
        • NSX Edge VTEP: Used for data plane traffic between the ESXi host and NSX Edge.
        • NSX VTEP: Used for data plane traffic between ESXi hosts.
        • vMotion: Used for vMotion (VMware migration tool) management and workload.
        • vSAN: Used for vSAN (VMware storage) data traffic.
        • vSphere: Used for management of the SDDC components (ESXi, vCenter, NSX-T, and NSX Edge). If you selected the Enable HCX check box in step 3, verify that the VLAN selected for vSphere contains a route table rule that allows traffic to the NAT gateway. For more information, see VLANs
        • HCX: Used for HCX traffic. This VLAN appears only if you selected the Enable HCX check box.
        • Replication Net: Used for the vSphere Replication engine. (VMware version 7.x only)
        • Provisioning Net: Used for virtual machine cold migration, cloning, and snapshot migration.
  8. (Optional) Provide a cluster workload CIDR block for the workflow to create an initial logical segment for the VMs. The value must be /30 or larger and must not overlap with the VCN or the cluster network CIDRs. Note that you can add network segments for the cluster in NSX Manager after the SDDC is provisioned.
  9. Click Next to advance to the Datastores page.
     The workflow automatically creates a management datastore with 8 TB capacity and VPUs/GB 10 (Balanced). If you want more storage for the cluster, you can create more block volumes here.
     1. Click Create block volume.
     2. Enter the required information for the block volume. For information about block volume configuration, see Creating a Block Volume.
     3. Click Submit.
  10. Click Next.
  11. (Optional) Enable monitoring and provide information about alarms and notifications. For more information, see Configuring Notifications.
      1. (Optional) Enable instance alarms and provide information about the alarm. To see the Interval and Trigger delay fields, click Show default alarm values.
         • Alarm name prefix: Each bare metal ESXi host has a separate alarm created for it. Enter a prefix that appears at the beginning of the alarm names for this SDDC.
         • Alarm severity: Choose a severity for the alarm: Info, Warning, Error, or Critical. All nonzero health issues for a bare metal instance triggers an alarm with the selected severity.
         • Interval: Select the interval at which the metric is emitted. The default is 1 minute.
         • Trigger delay: Select the number of minutes that the condition must be maintained before the alarm is in firing state. The default is 1 minute.
      2. Select an existing notification topic, or create a new one. If you select Create new, enter the following information:
         • Topic name: Enter a friendly name for the notification topic.
         • Subscription protocol: Select the protocol that you want to use to receive notifications. The default is email.
         • Email address: Enter the email address or address list that you want to send notifications to.
         • URL: If you select the Pager Duty protocol, enter a URL to send notifications to.
         • Notification compartment: Choose a compartment for the notification.
      3. Choose events that you want to receive notifications for. By default, all available notifications are selected.
         • To deselect a notification event, click the X on the notification.
         • To reselect a notification event, click the selection field and select the notification from the list.
