Automatic placement of clients in a distributed computer system satisfying constraints

摘要

A cloud management server and method for performing automatic placement of clients in a distributed computer system uses a list of compatible clusters to select an affinity cluster to place the clients associated with an affinity constraint. As part of the placement method, a cluster that cannot satisfy any anti-affinity constraint associated with the clients and the affinity constrain is removed from the list of compatible clusters. After the affinity cluster has been selected, at least one cluster in the distributed computer system is also selected to place clients associated with an anti-affinity constraint.

1. A method for performing automatic placement of clients in a distributed computer system, the method comprising:
selecting an affinity constraint associated with a first set of clients; determining whether any of the clients associated with the affinity constraint is associated with any anti-affinity constraint; removing a cluster of host computers that cannot satisfy the any anti-affinity constraint from a list of compatible clusters of host computers in the distributed computer system, the compatible clusters being clusters that are compatible with the clients associated with the affinity constraint; selecting an affinity cluster from the list of compatible clusters to place the clients associated with the affinity constraint; selecting an anti-affinity constraint associated with a second set of clients; and selecting at least one cluster in the distributed computer system to place the clients associated with the anti-affinity constraint.
