Glossary

A

AES128

Advanced Encryption Standard (AES). A symmetric-key algorithm specification used to encrypt data. AES supersedes DES.

D

DES

Data Encryption Standard. An algorithm specification used to encrypt data.

DHCP

Dynamic Host Configuration Protocol. The IP address is assigned by an external DHCP server.

F

F2-12

Oracle Fabric Interconnect F2-12 chassis.

fabric interconnect

Short name for an IB switch that provides gateway services and additional functionality.

H

HA

High Availability.

HCA

Host Channel Adapter. An InfiniBand network interface card used in an InfiniBand network. An HCA provides high-speed connectivity and virtual interfaces, based on the InfiniBand interface. An HCA can have 1 or 2 ports.

I

IB

InfiniBand. A high bandwidth messaging technology used for very high performance computing.

IMS

Identity Management System.

I/O

Input/Output. In computer architecture, the combination of the CPU and main memory (i.e., memory that the CPU can read and write to directly, with individual instructions) is considered the heart of a computer. Any movement of information to or from that complex, for example to or from a disk drive, is considered I/O.

I/O module

A user-replaceable physical interface component for the virtualization switch. I/O modules are supported only on this switch.

I/O Port

A single port on an Ethernet module, a Host Bus Adapter module, or one of the 38 InfiniBand server ports.

K

key set

Key sets are used for enhanced security. For examples, see show ib.

L

LAG

Link Aggregation Group.

leaf switch

Oracle InfiniBand Switch IS2-46.

M

MD5

MD5 message-digest algorithm used to verify data integrity.

MTU

Maximum Transmission Unit. An MTU is the largest physical packet size (in bytes) that a network can transmit. MTU values are only applicable to Ethernet ports, and the MTU of the I/O port must match the MTU of the neighboring switch.

O

OpenSM

The default Subnet Manager running on the Oracle Fabric Interconnect.

PVI

Private Virtual Interconnect. Connects the switch to the fabric and manages those Ethernet connections.

S

switch

Oracle InfiniBand Switch IS2-46.

SHA

Secure Hash Algorithm.

P

PVI

Private Virtual Interconnect used for cloud computing.

S

SCP

System Control Processor.

SM

Subnet Manager. SM groups manage and monitor an IB subnet.

SNMP

Simple Network Management Protocol. A protocol for collecting and organizing information about managed devices on an IP network.

V

vHBA

Virtual Host Bus Adapter. Connects a computer, which acts as the host system, to other network and storage devices.

virtualization switch

Oracle Fabric Interconnect F2-12 Switch. This virtualization switch supports several I/O modules that provide FC and Ethernet connectivity.

VLAN

Virtual local area network. A private, independent, logical network that is created within a physical network. A VLAN behaves like an ordinary LAN, but connected devices don't have to be physically connected to the same network segment.

vNIC

Virtual Network Interface Card. An Ethernet interface that is provided without a physical NIC.
