These key terms are relevant to the Oracle SPARC Model 300 Service.
Instance. An Oracle VM Server for SPARC domain in the Oracle SPARC Model 300 Service. Oracle creates instances for your service with a specific machine image and set CPU, memory, and network resources. See Learn About Instance Configurations.
IP reservation. A public IP address that you can route to an Oracle Compute Cloud Service instance that requires access to or from the Internet or other Oracle services. See About Public IP Addresses.
Oracle CPU (OCPU). For this service, an OCPU provides CPU capacity equivalent to one physical core of an Oracle SPARC M7 processor.
Storage volume snapshot. A backup of all data currently stored on a storage volume. Use this snapshot to restore or clone a storage volume. See Create a Volume Snapshot.
Virtual network device (VNIC). A pseudo network interface created on top of a network datalink device such as the provided LACP aggregation or native i40ge devices. VNICs can have specific IP, VLAN, and MTU definitions as required by the customer (within the restrictions imposed by the OPC service).
Volume. A disk storage location implemented as a volume (iSCSI LUN) on the ZFS Storage Appliance.
VPN endpoint. A VPN tunnel between your datacenter and your Oracle Compute Cloud Service site.
Zone. A zone provides a virtual mapping from the application to the platform resources. Zones allow application components to be isolated from one another even though some zone types share a single instance of the Oracle Solaris operating system. Zones use resource management components to control how applications use available system resources.
In the Oracle SPARC Model 300 Service, you can create an Oracle Solaris Native Zone, Oracle Solaris Kernel Zone, or Oracle Solaris Legacy Zone in a specific instance to create additional virtual environments. See Zone Brands for a description of the different zone types.
