the ESX cluster itself, because it is managed in vCenter Server. See Deactivate a compute node
(page 106), and Delete a compute node (page 107).
When the delete action is used on KVM compute nodes, the DHCP lease is expired and the compute
node is no longer manageable from CloudSystem.
Understanding compute node data
You can click the icon next to an ESX cluster or KVM compute node on the overview screen to
show all available data.
Two groups of horizontal graphs display when the compute data is expanded. The top set of
graphs show the allocation usage of the instances. See Calculating the number of instances that
can be provisioned to a compute node (page 105). The bottom set of graphs show the physical
usage of the instances.
Allocation graphs
These graphs show the virtual size, which is the physical size multiplied by the oversubscription
rate. For clusters, this is the aggregate value of all hypervisors in the cluster.
• CPU allocation: Amount of CPU cores designated for instances
• Memory allocation: Amount of memory designated for instances
• Storage allocation: Amount of compute storage designated for instances
Physical usage graphs
These graphs show the physical size information. For clusters, this is the aggregate value of all
hypervisors in the cluster.
• CPU usage: Number of actual CPU cores consumed by instances within the last five minutes
• Memory usage: Amount of actual memory consumed by instances within the last five minutes
• Storage usage: Amount of actual compute storage consumed by instances within the last five
minutes
When one or more virtual machine instances are attached to an ESX cluster or KVM compute node,
you can click the instance link next to Contains. The link takes you to the Instances screen, where
you can view the Instance details.
The Dashboard provides another view of compute node resources. See Interpreting the Dashboard
data (page 114).
Adding compute nodes to the cloud
Compute nodes are added to the cloud in different ways, depending on the type of compute node
you want to add.
ESX clusters appear on the Compute Nodes screen after you complete the following two steps:
• Register the management VMware vCenter Server. This action provides CloudSystem Foundation
with the location and credentials of the vCenter Server managing the ESX cluster.
• Import a cluster. This action calls vCenter Server and retrieves information about an ESX cluster.
The cluster is added to the Compute Nodes overview screen in an Unknown state. The first
time a cluster is imported, the proxy appliance establishes communication between vCenter
Server and the CloudSystem Console. The proxy appliance can support up to 12 ESX clusters.
When more than 12 ESX clusters are imported, a new proxy appliance is spawned.
KVM compute nodes are issued a DHCP lease from the Cloud Management Network, and then
they appear on the Compute Nodes screens in an Unknown state.
After an Activate action is performed, ESX clusters and KVM compute nodes are ready to host
instances.
