SDDC ROBO differentiates between different types of pods including the management pod, consolidated pod and storage pod.
The management pod resides in the hub (defined in About Hubs and Remote Office and Branch Office Sites) and runs the virtual machines that manage the SDDC. The management pod is instantiated as part of the VMware Validated Design for SDDC. The management pod is a pre-requisite for creating consolidated pod's in ROBO locations. For additional information on the management pod refer to the VMware Validated Design for SDDC.
The consolidated pod runs the following services in the ROBO location:
Virtual machines to manage the SDDC such as vCenter Server, NSX components, Remote Collectors, agents and other shared components.
Required NSX services to enable north-south routing between the SDDC and the external network, and east-west routing inside the SDDC.
SDDC tenant virtual machines to support workloads of different Service Level Agreements (SLAs).
Because this pod supports all SDDC, network, and production workloads at a remote office, it is important to ensure highly available physical components such as HVAC, power feeds and power supplies.
Storage pods provide network-accessible storage using NFS or iSCSI. Different types of storage pods can provide different levels of SLA, ranging from just a bunch of disks (JBODs) using IDE drives with minimal to no redundancy, to fully redundant enterprise-class storage arrays. For bandwidth-intense IP-based storage, the bandwidth of these pods can scale dynamically.
The VMware Validated Design for ROBO uses VMware vSAN as its primary storage platform, and does not consider block or file storage technology for primary storage. These storage technologies are only referenced for specific use cases such as backups to secondary storage.
