Auto Service Request. Oracle software that provides the ability to notify Oracle Support automatically.
Label of the PCIe hot-plug carrier.
Chip multiprocessing. Each CMIOU contains 1 CMP. The SPARC M8-8 and SPARC M7-8 servers can contain a maximum of 8 CMPs. The SPARC M7-16 server can contain a maximum of 16 CMPs.
Chip multithreading. Processor technology enabling multiple hardware threads (also known as strands) to execute on the same chip, through multiple cores per chip, multiple threads per core, or through a combination of both.
Domain configurable unit. The smallest building block for PDomains. SPARC M8-8 and SPARC M7-8 servers with two PDomains have two DCUs, and SPARC M8-8 and SPARC M7-8 servers with one PDomain have one DCU. Those DCUs are static. Their assignment cannot be changed. The SPARC M7-16 server has four DCUs that you can assign to the host in any one of the four possible PDomains. See also PDomain.
Dynamic Host Configuration Protocol. Software that automatically assigns IP addresses to clients on a TCP/IP network. The SPs do not support DHCP. You must assign static IP addresses to SP components.
Embedded USB. A flash-based drive designed specifically to be used as a boot device. An eUSB does not provide storage for applications or customer data.
Fault management architecture. Generates fault indictments from the SP. FMA provides three system activities: error handling, fault diagnosis, and response.
Names used to identify hardware components in certain Oracle ILOM and system commands and messages.
See Oracle ILOM.
A networking communications standard that features very high throughput and very low latency.
IP network multipathing. An Oracle Solaris feature providing multipathing and load-balancing capabilities for IP network interfaces.
Internet protocol over InfiniBand.
Internet small computer system interface. An IP-based storage networking standard that enables a server to access storage across a network. In an iSCSI network, the remote storage is called the iSCSI target.
A virtual machine comprising a discrete logical grouping of resources that has its own operating system and identity within a single computer system.
Multipathing. See also multipathing.
Multipathing I/O. An Oracle Solaris feature enabling you to configure the multipathing features of FC devices to control all supported FC HBAs.
Multipathing software enables you to define and control redundant physical paths to I/O devices such as storage devices and network interfaces.
Network management. The NET MGT ports provide Ethernet connections to the SPs. Dedicated SPARC M7-16 server NET MGT ports connect the four SPPs to the two SPs.
Non-Volatile Memory Express. A specification for accessing solid-state drives attached through the PCIe bus.
Oracle firmware that enables a PDomain to boot the Oracle Solaris OS. Provides an interface for testing hardware and software interactively.
Oracle Integrated Lights Out Manager. The system management firmware that is preinstalled on the server SPs.
Oracle Validation Test Suite. An application that exercises the system, provides hardware validation, and identifies possible faulty components.
An enclosure used to install and house PCIe cards in the server. See CAR.
Physical domain. SPARC M8-8 and 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.
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 SPMs 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.
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.
Predictive self healing. A system of technologies that includes FMA, ereports, diagnosis engines, and agents that continuously monitor the health of the server and can take a faulty component offline if needed.
In a PCIe device path, the root port is always the second element (for example, /pci@300/pci@0).
Service processor. For redundancy, the server contains two service processors, one active and one on standby.
Service processor proxy. One SPP is assigned to manage each PDomain. SPPs monitor environmental sensors and manage the CMIOUs, memory controllers, and DIMMs within the DCU. See also DCU SPM and PDomain SPM.
A device that enables the CMIOUs to communicate with each other. The SPARC M7-16 server switch contains six switch units.
In the SPARC M8 and SPARC M7 servers documentation, system refers to the /System level in the Oracle ILOM firmware.
