The service plans you choose determines how memory is allocated to the cluster processes. One consideration is how much memory is available in each VM.
Memory allocation depends on whether a plan is colocated or non-colocated:
A colocated plan is one in which each VM hosts one locator and one server. For example, the default
small-footprint plan comprises three locators and three servers hosted on three VMs.
A non-colocated plan is one in which each locator or server runs in its own VM. For example, the default medium plan comprises three locators and four servers, each running in its own VM, for a total of seven VMs.
The following sections describe how VMware Tanzu GemFire for VMs allocates memory based on the total memory of each VM.
Server heap is reduced to accommodate the Anti-Virus and File Integrity Monitoring (FIM) add-ons, if they are present.
Under non-colocated plans, each VM hosts one cluster member, either a locator or a server.
Server heap is reduced to accommodate the Pivotal Anti-Virus and File Integrity Monitoring (FIM) TAS for VMs add-ons, if they are present.
