SER MGT
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
Power-on self-test. Diagnostic software that runs when the server boots.
PROM
Programmable read-only memory.
PSH 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.
R
RC
Root complex. The first element in a PCIe device path (for example,
/pci@300
).
rKVMS Remote keyboard video mouse and storage.
root port
In a PCIe device path, the root port is always the second element (for example,
/pci@300/
pci@0
).
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 ).
SER MGT
Serial management. The SER MGT ports provide serial connections to the SPs.
