16 Compute node creation
Compute nodes manage the resources required to run instances in the cloud. In CloudSystem, two
types of compute nodes are supported: ESX and KVM.
• You create and manage ESX compute hosts in vCenter Server. All compute hosts are configured
as clusters and must be imported into CloudSystem. After import, you can activate clusters
and create instances that consume the resources.
• You create KVM compute nodes on KVM hosts. After a compute node is created, the Data
Center Management Network allows CloudSystem to see the compute node. The compute
node displays on the Compute Nodes overview screen in an Unknown status, meaning it is
not yet activated. After activating the compute node, you can create instances that consume
the resources.
Preparing compute nodes
To determine the size of your compute node, answer the following questions.
• What flavor settings will the provisioned instances use? See About Flavors (page 109).
• What oversubscription rate is supported for each compute resource? See Calculating the
number of instances that can be provisioned to a compute node (page 105).
• How many instances will each compute node support?
After answering the questions above, determine the amount of CPU cores, memory and storage
to allocate to each compute node. You might want to consider Maximum supported configuration
values for each CloudSystem (page 71).
Creating ESX compute hypervisors
ESX compute hosts are created inside clusters in vCenter Server. Consult VMware documentation
for instructions on creating and configuring compute hosts in vCenter Server.
See VMware vSphere Documentation at VMware for all details on using and configuring vSphere
software.
Preparing or completing each of the following requirements can help to ensure success in creating
a correctly configured ESX cluster for import into CloudSystem.

Information Library.
A management hypervisor is fully configured in a cluster in
vCenter Server and the base appliance, SDN appliance, and
network node appliances are created. You can create some
compute hosts in the management vCenter Server, but HP
recommends creating them in a separate compute vCenter
Server.
VMware vSphere DocumentationA compute Datacenter is set up and contains a cluster and
compute hosts. DRS is enabled.
VMware vSphere DocumentationSupported software for the host is ESXi 5.0.3, 5.1.2 and 5.5
(Custom HP image)
--The host name for each compute host in the cluster has a
matching host name in any connected 3PAR storage system.
