Ensure Consistency for Compliance
Configuration settings that are shared by a group of VMware vSphere® hosts are stored in a host profile. Once the host profile has been created, it can be attached to one or more vSphere hosts or clusters. Once attached, the host configuration is compared against the host profile and any deviations are reported. Administrators associate host profiles with other hosts and clusters, ensuring consistency. Any drift in configurations can be corrected automatically.
Reduce the Time Needed to Set Up New Hosts
New hosts that are added to VMware® vCenter Server™ can be configured by applying the host profile. Using this configuration management feature, administrators can create a profile once then use it for multiple vSphere hosts, providing fast setup. This automation feature also eliminates the need to set up specialized scripts or manually configured hosts.
Apply the Same Change to Multiple Hosts
When firmware upgrades or other events happen that require storage, network or security configuration changes on multiple hosts in a cluster, administrators can edit the host profile and apply it across the cluster for consistent configuration updates. In addition, the administrator can remove any settings that must be excluded from the host profile check.
VMware vCenter Server is used to create and maintain the host profiles that configure the hosts.
Host profiles are typically created using a reference host as a template, or master configuration. Each host profile is assigned a reference host. A host profile’s reference host can be changed to accommodate adding and removing hosts to or from the vCenter Server inventory.
Configuration settings that are not shared between hosts, such as IP addresses, are captured in a unique, host-specific answer file. When the host profile is applied, or any time a compliance check is initiated, the active host configuration is checked against both the answer file and the host profile.
