VxRail is dependent of specific data center services to implement the cluster and for day-to-day operations.
The ToR switches must be configured to the upstream network to enable connectivity to these data center services, and to enable connectivity to the end-user community.
Data center services
Requirements and options for data center services include:
- Domain Naming Services (DNS) is required to deploy the VxRail cluster and for ongoing operations. You can choose a DNS service internal to VxRail, or use a DNS service in your data center.
- VxRail cluster requires synchronization of the clock settings on the various VxRail components to ensure proper operations. Dell Technologies recommends using a reliable global timing service for VxRail such as Network Time Protocol (NTP) for this purpose.
- Syslog service is supported with VxRail, but is not required.
- VxRail depends on VMware vCenter Server for cluster management and operations. You can use either the embedded VMware vCenter Server instance that is included with VxRail, or a customer-managed VMware vCenter Server instance in your data center.
