Peripheral Component Interconnect Express

PEU

PCIe unit (physical, data link, and switch transaction layers)

PF

physical function device

R

RARP

Reverse Address Resolution Protocol

RCR

receiver

REM

RAID Expansion Module

RSS

Receive-Side Scaling

RSS enables packet receive-processing to scale with the available computer processors. Enabling RSS allows the network load from a network adapter to be balanced across CPUs while maintaining in-order delivery of data. This delivery is enabled with RSS by ensuring that the packets from a single TCP connection are processed on one CPU.

RX

receive

S

SAS2 NEM

A generic term that applies to any NEM that supports SAS2 connectivity

SEL

system event log

SerDes

Serializer/Deserializer

server module

Any server module (blade) that will interoperate with a storage module (blade). For a server module to work with a NEM, the server module must have a SAS2 REM installed. The terms server module and server blade are used interchangeably.

SFP+

Small form-factor pluggable

SLES

SUSE Linux Server

SMF

single-mode fiber

SR-IOV

Single Root I/O Virtualization is a PCI Express Extended capability that makes one physical device appear as multiple virtual devices.

storage module

The Sun Blade 6000 Module M2. The terms storage module and storage blade are used interchangeably.

Sun ASIC

Sun application-specific integrated circuit
