Data center network
VxRail depends on specific data center services to implement the cluster for day-to-day operations. Configure the ToR switches to the upstream network to connect to data center services and to enable connectivity to the end-user community.
Data center services
The following requirements and options apply for data center services:
- DNS is required to deploy the VxRail cluster and for ongoing operations. You can use internal 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. Use a reliable global timing service for VxRail such as NTP for this purpose.
- Syslog service is supported, but not required, with VxRail.
- 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.
