SDDCs
Learn how to create and manage SDDCs using Oracle Cloud Infrastructure VMware Solution.
There are two types of SDDC configuration available: a multi-host SDDC, and a single-host SDDC used for testing and short-term development.
Multi-Host SDDCs
A multi-host SDDC has the following properties:
- From 3 to 64 ESXi hosts on supported OCI bare metal compute instances
- A version of VMware software on each ESXi host
- A subnet and VLANs in an OCI VCN
Multi-host SDDCs provide high availability and you can use the full range of VMware Solution features to migrate and support your production workloads.
Using dense shapes, you can start with 3 ESXi hosts and scale up to 64 hosts in a single SDDC. If you use standard shapes, you can start with 3 ESXi hosts and scale up to 8 hosts in a single ESXi cluster within the SDDC.
Single-Host SDDCs
A single-host SDDC has the following properties:
- A single ESXi host on an OCI bare metal dense shape instance
- A version of VMware software on each ESXi host
- A subnet and VLANs in an OCI VCN
Use cases for a single-host SDDC:
- Accelerated onboarding for proof-of-concept, or testing and development.
- Migration between on-premises and OCI VMware Solution using VMware HCX, VMware vMotion for live migration, and cold migration.
- Disaster Recovery Evaluation with VMware Site Recovery (SRM) optimized for OCI VMware Solution. VMware SRM is purchased separately.
- Hybrid Linked Mode support for a single view of on-premises and OCI VMware Solution resources.
- High-bandwidth, low-latency access to other Oracle services.
Limitations and Considerations for Single-Host SDDCs:
- Standard shapes are not supported.
- Production workloads are not supported.
- No OCI-supported service-level agreement (SLA) is provided.
- Oracle support is limited to commercially reasonable support. VMware support is available only for the first 60 days for a single-node SDDC deployment.
- Single-host SDDCs don't expire, but they are limited to the Hourly and Monthly billing options. See Billing Options for more information.
- Single-host SDDCs aren’t designed as long-term solutions. If you require a long-term SDDC, you can migrate your workloads to a new production SDDC using HCX. See HCX License Types for more information.
- Single-host SDDCs are not backed up. If the host fails, your data is lost.
- You are limited to a global maximum of 10 single-host SDDC deployments across all tenancies and regions.
- Features that require more than one host, such as the following ones, don’t work:
- Distributed management components
- High-availability (HA) for VMware clustering
- Distributed Resource Management (DRM) for VMware clustering
