Sun Microsystems X4200 M2 manual Glossary, Pci-E

	Glossary
Chipkill	A technology developed by IBM for situations that demand high
	availability. It allows a system (usually CPU or motherboard) to detect
	problems with the computer’s memory and selectively disable the
	problematic DIMMS.
ECC	Error Correcting Code. A type of memory that corrects errors on the fly.
PCI-E	Peripheral Component Interconnect Express. Formerly known as third-
	generation I/O, this implementation of the PCI computer bus that uses
	existing PCI programming concepts and communication standards, but
	bases it on a much faster serial communications system.
PCI-X	Peripheral Component Interconnect Extended. A computer bus technology
	that increases the speed that data can move within a computer from
	66 MHz to 133 MHz.
SAS	Serial Attached SCSI. The successor to the original SCSI technology with
	the ability to address up to 16,256 devices per port. It also has a more
	reliable point-to-point serial connection at speeds of up to 3 Gbps.

Ethernet 10/100/1000Base-T The most widely used LAN access method defined by the IEEE 802.3

	standard; uses standard RJ-45 connectors and telephone wire. 100Base-T
	is also referred to as Fast Ethernet. And 1000Base-T is also referred to as
	Gigabit Ethernet.
IKE	Internet Key Exchange. A method for establishing a security association
	that authenticates users, negotiates the encryption method and exchanges
	the secret key. IKE is used in the IPSec protocol.
I/O	Input/output. Transferring data between the CPU and any peripherals.
IPSec	IP Security. A security protocol from the IETF (Internet Engineering Task
	Force) that provides authentication and encryption over the Internet.
	Unlike SSL, which provides services at layer 4 and secures two
	applications, IPSec works at layer 3 and secures everything in the
	network.
IPMI	Intelligent Platform Management Interface. System management
	architecture for providing an industry-standard interface and methodology
	for system management.
L2 cache	Also referred to as Ecache or External Cache. A memory cache external to
	the CPU chip. The AMD Opteron processor integrates 1 MB of L2 cache
	per CPU.
MTBF	Mean Time Between Failures. The average time a component works
	without failure.
SNMP	Simple Network Management Protocol. A set of protocols for managing
	complex networks. The first versions of SNMP were developed in the
	early 80s. SNMP works by sending messages, called protocol data units
	(PDUs), to different parts of a network. SNMP-compliant devices, called
	agents, store data about themselves in Management Information Bases
