NPAR
NIC 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 NIC, FCoE, and 
iSCSI.
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.
NVMe
A storage access method designed for 
sold-state drives (SSDs).
OFED™
OpenFabrics Enterprise Distribution. An 
open source software for RDMA and 
kernel bypass applications.
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.

See QoS.
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.

RISC
Reduced instruction set computer. A 
computer microprocessor that performs 
fewer types of computer instructions, 
thereby operating at higher speeds.
RDMA over Converged Ethernet
See RoCE.
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.
