Each vCenter Server component or service has a set of dependencies. The following diagram illustrates the core vCenter Server dependencies:

As with earlier vCenter versions, the vCenter 6.7 Windows installation media includes several other tools that provide support and automation to deploy, manage, patch, and monitor the vSphere virtual environment. These tools can be installed on the same server as other vCenter Server components, or on a separate server. The tools that are included are as follows:

• VMware vSphere Update Manager (VUM): This provides a central automated patch and version management for ESXi hosts and virtual appliances. VUM can be installed on the vCenter Server when running on Windows, but it must be installed on a separate Windows server when using the VCSA.
• ESXi Dump Collector: This collects memory dumps over the network in the event of an ESXi host encountering a critical error.
• VMware vSphere Syslog Collector: This enables network logging and combines the logs from multiple hosts.
• VMware vSphere Auto Deploy: This provides the automated deployment and configuration of ESXi hosts.
