What is a Host Aggregate

A Host aggregate is a group of hosts that share a common attribute or capability, eg a group of hosts with same hardware configuration.

You can create efficient and scalable resource tiers using host aggregates.

You can do the following with host aggregates.

• Create virtual clusters or tiers of resources by grouping together one or more hypervisors by using simple key-value pair tagging.
• Utilize the tiers across different tenants, to restrict placement of specific groups of virtual machines solely to the tier that is applicable to them.

For example, a solid state drive (SSD) tier can be created to ensure that all production workloads get efficient and fast storage I/O access. Similarly, a production tier and development-test tier strategy can be used to separate your workloads.
