The following appliance is automatically created after an ESX cluster is imported. (No proxy
appliances are started in a KVM-only environment.)
Proxy appliance Acts as a communication mechanism between OpenStack technology
and VMware vCenter Server, and runs the OpenStack agents for up to
twelve clusters for each vCenter Server. Additional appliances are
automatically created when the number of new clusters added to the cloud
are reached. New proxy appliances are created with the first, 13th, and
25th cluster additions.
Storage
CloudSystem works with HP 3PAR StoreServ Storage, a cluster-based storage architecture that
incorporates data management and fault tolerance technologies that can meet the storage needs
of smaller sites and can be scaled for global organizations.
3PAR storage is required to create block storage for VM guests.
Storage for manually provisioned hypervisor hosts is more flexible, and can include local disks.
Virtual server storage
Virtual server storage connects the 3PAR storage system to virtual machine instances. Options
include:
• Fibre Channel Storage Area Network (FC SAN), which provides block-level storage that can
be accessed by the applications running on any networked servers
• Direct-Attach Fibre Channel Storage, a single-layer Fibre Channel storage network that
eliminates SAN switches and HBAs (host bus adapters)
• iSCSI, which is block-level storage that uses traditional Ethernet network components for
connectivity
Physical servers
Servers running an ESX cluster or a KVM hypervisor can be used as a management cluster, a
management hypervisor, or as compute clusters or nodes.
Management cluster or hypervisor Clustered or standalone hypervisors that host the virtual
machine appliances that comprise the CloudSystem solution.
There are three possible configurations:
• An ESX management cluster that hosts the virtual
machines running CloudSystem and its integrated tools.
• A standalone ESX management hypervisor that hosts
the virtual machines running CloudSystem and its
integrated tools.
See also Integrated tool connectivity and configuration
(page 81).
• A KVM management hypervisor that hosts the virtual
machines running CloudSystem software.
Compute nodes ESX clusters and KVM hosts that provide the pool of
hypervisor resources used to provision virtual machine
instances.
User authentication
You can choose one of two methods of user authentication. If you use local logins, CloudSystem
provides local authentication for users authorized to access CloudSystem. The Infrastructure
administrator enters user data, which is saved in the appliance database. When anyone tries to
