NIC
Network interface card. Computer card
installed to enable a dedicated network
connection.

NPAR
partitioning. The division of a single
NIC port into multiple physical functions or
partitions, each with a user-configurable
bandwidth and personality (interface type).
Personalities include
, and
.
NVRAM
Non-volatile random access memory. A
type of memory that retains data (configu-
ration settings) even when power is
removed. You can manually configure
NVRAM settings or restore them from a
file.
PCI™
Peripheral component interface. A 32-bit
local bus specification introduced by
Intel
®
.
PCI Express (PCIe)
A third-generation I/O standard that allows
enhanced Ethernet network performance
beyond that of the older peripheral compo-
nent interconnect (PCI) and PCI extended
(PCI-X) desktop and server slots.
QoS
Quality of service. Refers to the methods
used to prevent bottlenecks and ensure
business continuity when transmitting data
over virtual ports by setting priorities and
allocating bandwidth.

.
PF
Physical function.
RDMA
Remote direct memory access. The ability
for one node to write directly to the
memory of another (with address and size
semantics) over a network. This capability
is an important feature of VI networks.

remote direct memory access
RISC
Reduced instruction set computer. A
computer microprocessor that performs
fewer types of computer instructions,
thereby operating at higher speeds.
RDMA over Converged Ethernet
.
RoCE
RDMA over Converged Ethernet. A
network protocol that allows remote direct
memory access (RDMA) over a converged
or a non-converged Ethernet network.
RoCE is a link layer protocol that allows
communication between any two hosts in
the same Ethernet broadcast domain.
