public class HostSimple
extends HostAbstract

A Host class that implements the most basic features of a Physical Machine (PM) inside a Datacenter. It executes actions related to the management of virtual machines (e.g., creation and destruction). A Host has a defined policy for provisioning memory and bw, as well as an allocation policy for Pes to Virtual Machines. A Host is associated with a Datacenter and can run virtual machines.

Since:

CloudSim Toolkit 1.0

Constructor Details

HostSimple

public HostSimple(List<Pe> peList)

Creates and instantaneously powers on a Host without a pre-defined ID. It sets 10 GB of RAM, 1000 Mbps of Bandwidth and 500 GB of Storage. It uses a ResourceProvisionerSimple for RAM and Bandwidth. Finally, it sets a VmSchedulerSpaceShared as default. The ID is automatically assigned when a List of Hosts is attached to a Datacenter.

Parameters:

peList - the host's Pe list

• HostAbstract.setRamProvisioner(ResourceProvisioner)
• HostAbstract.setBwProvisioner(ResourceProvisioner)
• HostAbstract.setVmScheduler(VmScheduler)

HostSimple

public HostSimple(List<Pe> peList,
 boolean activate)

Creates a Host without a pre-defined ID, 10 GB of RAM, 1000 Mbps of Bandwidth and 500 GB of Storage and enabling the host to be powered on or not.

It creates a ResourceProvisionerSimple for RAM and Bandwidth. Finally, it sets a VmSchedulerSpaceShared as default. The ID is automatically assigned when a List of Hosts is attached to a Datacenter.

Parameters:

peList - the host's Pe list

activate - true to power the Host on, false to power off (see ExecDelayableAbstract.setStartupDelay(double))
