NVMe N NVMe Non-Volatile Memory Express. A specification for accessing SSDs attached through the PCIe bus. NVRAM Non-volatile random-access memory. O OpenBoot Oracle firmware that enables a PDomain to boot the Oracle Solaris OS. Provides an interface for testing hardware and software interactively. Oracle ILOM Oracle Integrated Lights Out Manager. The system management firmware that is preinstalled on the server SP s. Oracle VTS Oracle Validation Test Suite. An application that exercises the system, provides hardware validation, and identifies possible faulty components. OS Operating system. P PCIe Peripheral Component Interconnect Express. PCIe hot-plug carrier An enclosure used to install and house PCIe cards in the server. See CAR . PDECB Power distribution electronic circuit breaker. PDomain Physical domain. The SPARC M7-8 servers are configured with either two PDomains or one PDomain. These PDomains are static and cannot be reconfigured. The SPARC M7-16 server can have one to four configured PDomains. These PDomains are dynamic. With dynamic PDomains, you can assign or unassign the DCUs in the PDomains as long as you stop and start the host. See also DCU and switch unit . PDomain SPM The lead SPM of a PDomain. The PDomain SPM manages tasks and provides rKVMS service for that PDomain. In a SPARC M7-16 server, Oracle ILOM identifies one of the DCU SPM s from the pool of DCU SPMs on the same PDomain as the PDomain SPM to manage activity on that host. See also PDomain and SPM . 52 SPARC M7 Series Servers Product Notes • October 2016

Standby SP pool A logical group of devices describing the layout and physical characteristics of the available storage. Storage space for datasets is allocated from a pool. ZFS uses a model where storage devices are aggregated into a storage pool. R RC Root complex. The first element in a PCIe device path (for example, /[email protected] ). rKVMS Remote keyboard video mouse and storage. S scalability The ability to increase (or scale up ) processing power in a server by combining the server's physical configurable hardware (see DCU ) into one or more logical groups (see PDomain ). SCSI Small computer system interface. See also iSCSI . SLink Scalability link. See also scalability . SP Service processor. For redundancy, the server contains two service processors, one active and one on standby. SPM Service processor module. A component of the SP s and SPPs. SPMs contain processors that enable the SPs and SPPs to manage the server resources. See also DCU SPM and PDomain SPM . SPP Service processor proxy. One SPP is assigned to manage each PDomain. SPPs monitor environmental sensors and manage the CMIOU s, memory controllers, and DIMM s within the DCU. See also DCU SPM and PDomain SPM .
