Management domain architecture The management domain is a cluster of physical hosts that contain the management component VMs. A region is a single instance of VCF that contains a separate VMware SDDC instance for VCF high availability. An availability zone in the management domain is a collection of infrastructure components. Each zone is isolated to prevent failure propagation or an outage that spans a data center. The management domain provides a single availability zone to protect against failure of individual hosts. VMware vSphere runs a dedicated VMware vCenter Server in the management domain with VMware vSAN storage. The management domain hosts VMware SDDC Manager, VMware NSX-T Managers, and AMP Central. If virtual network segments are used, two VMware NSX-T Edge node VMs connect the VMware NSX-T virtual network and the physical network components. Before you deploy the management domain, size AMP Central with the following considerations: Core, optional, ECO workloads Optional VMware vRealize Suite products and CPU and memory requirements, and associated reservations Storage requirements Child TopicsPhysical and logical architectureThe physical and logical topology of AMP Central aligns with the physical and logical requirements of VCF. See the Release Certification Matrix (RCM) for the supported VCF release. Network infrastructure The stand-alone AMP Central uses dedicated management and ToR Cisco Nexus switches. An integrated AMP Central shares the ToR and management switches between VCF servers and the VCF resources. Virtual infrastructure designThe VxBlock System 1000 and the management domain follow the VMware VVD recommendations that are incorporated into VMware VCF. Default VLANs, port groups, and VMsVMware Cloud Builder deploys two VMware vSphere Distributed Switches (VDS) and port groups that connect to the ToR switches. ScalabilityAMP Central with VCF aligns to the VMware Validated Designs (VVD) for VMware ESXi host CPUs with overcommitment recommendations. VxBlock System multisystem managementAMP Central uses available resources on the management workload cluster to manage one VxBlock System 1000 with VCF and multiple legacy VxBlock Systems. Legacy VxBlock Systems require a dedicated (non-VCF managed) VMware vCenter Server. Legacy VxBlock Systems must align to the VxBlock System RCM. You cannot convert or upgrade legacy VxBlock Systems to VMware VCF. Integrated Data ProtectionIntegrated Data Protection can be used on a VxBlock System 1000 with VCF for the management workload and the VI workload domain. Data Protection strategies range from basic backup and recovery to multisite data replication to support point-in-time recovery or an active/active data center. There are multiple solutions and strategies available for RTOs and RPOs.
