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

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.

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

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
