Virtual partition throttles control virtual partition resources when multiple entities share a platform. Priority allocations and hard limits control the CPU and I/O use in a virtual partition. However, those methods do not control other resources, such as AMP worker tasks. Virtual partition throttles cannot directly limit use of memory or AMP worker tasks. However, virtual partition throttles can have an indirect influence on their use.

A virtual partition throttle manages how many requests and utilities can run at the same time in the virtual partition. However, it does not count requests in Tactical workloads against the throttle limit.
