Glossary

A
Active SP

An SP selected by Oracle ILOM to manage server resources. When an Active SP can no longer serve this role, the Standby SP assumes its role. See also SP and Standby SP.

ASR

B
BoB

Memory buffer on board. An ASIC on a CMIOU board that transfers data between a DIMM and a CMP.

C
CAR

Label of the PCIe hot-plug carrier.

CMIOU

CPU, memory, and I/O unit. Each CMIOU contains 1 CMP, 16 DIMM slots, and 1 IOH chip. Each CMIOU also hosts an eUSB device.

CMP

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.

CMT

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.

D
DCU

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.

DCU SPM

In SPARC M8 and SPARC M7 servers, Oracle ILOM identifies one SPM from an SPM pair to manage DCU activity. See also SPM, SPP, and DCU.

DHCP

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.

DIMM

Dual in-line memory module.

dynamic PDomain

A SPARC M7-16 PDomain. After stopping the host, you can assign or unassign DCUs to or from a dynamic PDomain. See also static PDomain and PDomain.

E
EMI

Electromagnetic interference.

ESD

Electrostatic discharge.

eUSB

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.

F
FC

Fibre Channel. High-speed network technology primarily used to connect computer data storage.

FMA

Fault management architecture. Generates fault indictments from the SP. FMA provides three system activities: error handling, fault diagnosis, and response.

FRU name

Names used to identify hardware components in certain Oracle ILOM and system commands and messages.

G
GB

Gigabyte. 1 gigabyte = 1024 megabytes.

GbE

Gigabit Ethernet.

I
ILOM

See Oracle ILOM.

InfiniBand

A networking communications standard that features very high throughput and very low latency.

IOH

I/O hub.

IPMP

IP network multipathing. An Oracle Solaris feature providing multipathing and load-balancing capabilities for IP network interfaces.

IPoIB

Internet protocol over InfiniBand.

iSCSI

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.

iSCSI using IPoIB

A boot process that enables a server to boot an iSCSI target accessible using IP over an InfiniBand network. See also IPoIB.

K
KVMS

Keyboard video mouse storage.

KW

Kilowatt.

L
logical domain

A virtual machine comprising a discrete logical grouping of resources that has its own operating system and identity within a single computer system.

M
MIB

Management information base.

MP

Multipathing. See also multipathing.

MPxIO

Multipathing I/O. An Oracle Solaris feature enabling you to configure the multipathing features of FC devices to control all supported FC HBAs.

multipathing

Multipathing software enables you to define and control redundant physical paths to I/O devices such as storage devices and network interfaces.

N
NET MGT

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.

NTP

Network Time Protocol.

NVMe

Non-Volatile Memory Express. A specification for accessing solid-state drives attached through the PCIe bus.

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 SPs.

Oracle VTS

Oracle Validation Test Suite. An application that exercises the system, provides hardware validation, and identifies possible faulty components.

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. 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.

See also DCU, dynamic PDomain, static PDomain, 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 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.

PDU

Power distribution unit.

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.

POST

SNMP

Simple Network Mail Protocol.

SP
