NVMeNNVMeNon-Volatile Memory Express. A specification for accessing SSDs attached through the PCIebus.NVRAMNon-volatile random-access memory.OOpenBootOracle firmware that enables a PDomain to boot the Oracle Solaris OS. Provides an interfacefor testing hardware and software interactively.Oracle ILOMOracle Integrated Lights Out Manager. The system management firmware that is preinstalledon the server SPs.Oracle VTSOracle Validation Test Suite. An application that exercises the system, provides hardwarevalidation, and identifies possible faulty components.OSOperating system.PPCIePeripheral Component Interconnect Express.PCIe hot-plugcarrierAn enclosure used to install and house PCIe cards in the server. See CAR.PDECBPower distribution electronic circuit breaker.PDomainPhysical domain. The SPARC M7-8 servers are configured with either two PDomains or onePDomain. These PDomains are static and cannot be reconfigured. The SPARC M7-16 servercan have one to four configured PDomains. These PDomains are dynamic. With dynamicPDomains, you can assign or unassign the DCUs in the PDomains as long as you stop and startthe host.See also DCU and switch unit.PDomainSPMThe lead SPM of a PDomain. The PDomain SPM manages tasks and provides rKVMS servicefor that PDomain. In a SPARC M7-16 server, Oracle ILOM identifies one of the DCU SPMsfrom the pool of DCU SPMs on the same PDomain as the PDomain SPM to manage activity onthat host.

Standby SPpoolA logical group of devices describing the layout and physical characteristics of the availablestorage. Storage space for datasets is allocated from a pool. ZFS uses a model where storagedevices are aggregated into a storage pool.RRCRoot complex. The first element in a PCIe device path (for example, /[email protected]).rKVMSRemote keyboard video mouse and storage.SscalabilityThe ability to increase (or scale up) processing power in a server by combining the server'sphysical configurable hardware (see DCU) into one or more logical groups (see PDomain).SCSISmall computer system interface. See also iSCSI.SLinkScalability link. See also scalability.SPService processor. For redundancy, the server contains two service processors, one active andone on standby.SPMService processor module. A component of the SPs and SPPs. SPMs contain processors thatenable the SPs and SPPs to manage the server resources. See also DCU SPM and PDomainSPM.SPPService processor proxy. One SPP is assigned to manage each PDomain. SPPs monitorenvironmental sensors and manage the CMIOUs, memory controllers, and DIMMs within theDCU. See also DCU SPM and PDomain SPM.
