<h2 id="rzahqtermsandconcepts">Terminology</h2>
<p>The following are terms related to Windows environment on iSeries&trade;. For other iSeries terms and definitions, see the <a href="../rzaat/as4glos.htm">Information
Center glossary</a>.</p>
<dl><img src="delta.gif" alt="Start of change" />
<dt class="bold">Baseboard Management Controller (BMC)</dt>
<dd>A basic low function service processor that is used to control xSeries&reg; systems.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />
<dt class="bold">certificate</dt>
<dd>A standard format for combining
an identity with a public key, signed by a Certificate Authority, which is
valid from a specified start date/time until a specified end date/time. The
identity in a certificate (also called the "Subject" of the certificate) says
who or what the certificate was issued to. It can have a variety of syntaxes,
but usually contains a distinguished name with attributes like "CN=common
name, O=organization, OU=organizational unit". The public key is part of
a private/public key pair, usually one created for use with the RSA public
key cryptosystem. In contrast, the corresponding private key is not part of
the certificate, and is not intended to be viewed.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />
<dt class="bold">certificate authority</dt>
<dd>A private key/certificate
pair that can sign other certificates for authentication purposes, such as
determining if a certificate is really from who it claims to be from. A certificate
authority may be either owned by a third-party organization that verifies
identity information and issues signed digital certificates, or it may be
local and private. Once a certificate has been digitally signed, it cannot
be altered without detection.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />
<dt class="bold">Challenge Handshake Authentication Protocol (CHAP)</dt>
<dd>An authentication protocol that involves a secret known to both
the authenticator and the party being authenticated. The secret is protected
from eavesdropping during transmission.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />
<dt class="bold">connection security network server configuration</dt>
<dd>An i5/OS&trade; configuration object that is used to configure security-related
values that control how the iSCSI HBA SCSI and virtual Ethernet LAN data is
secured on the network. The corresponding i5/OS object type is *NWSCFG with a subtype
of *CNNSEC. This object is also referred to using the shorter term <span class="bold">connection security configuration</span>.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />
<dt class="bold">enclosure ID</dt>
<dd>The identifying serial
number, type and model of the enclosure containing the service processor.
For a standard xSeries server, the service processor and the xSeries server share
a common enclosure identifier. For an IBM&reg; BladeCenter&trade; server, this identifies the management
module which contains the IBM BladeCenter servers which it controls.</dd><img src="deltaend.gif" alt="End of change" />
<dt class="bold">Enterprise Identity Mapping (EIM)</dt>
<dd>A mechanism for
mapping/associating a person or entity to the correct user identities in various
registries across multiple operating systems. User Administration function
integrates user enrollment with EIM, by providing support for automatic creating
of EIM Windows source associations. Also, enrolled i5/OS user profiles allow Windows user profiles
to be different than the i5/OS user profile if the administrator has manually defined
the EIM Windows source association.</dd>
<dt class="bold">EIM identifier</dt>
<dd>Represents an actual person or entity
in EIM. When you create an EIM identifier you associate it with the user identity
for that person.</dd>
<dt class="bold">EIM identity mapping association</dt>
<dd> A single sign-on
environment is made possible by associating the user identity to an EIM identifier
in a registry. There are 3 types of associations, source, target, and administrative.
User enrollment integrates with EIM when a target i5/OS association and a source Windows association
are defined. The associations may be defined either automatically using the
user profile attribute, EIMASSOC, or by using iSeries Navigator to manually define the associations.
Target associations are primarily used to secure existing data. Source associations
are primarily used for authentication purposes.</dd>
<dt class="bold">external network</dt>
<dd><img src="delta.gif" alt="Start of change" />Networks accessed by
integrated servers through physical networking hardware. See also <span class="bold">virtual networks</span>.<img src="deltaend.gif" alt="End of change" /></dd><img src="delta.gif" alt="Start of change" />

<dd>A host bus adapter
(HBA) is an adapter card that plugs into the bus of the host system. For example,
an Ethernet adapter or an iSCSI adapter.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />
<dt class="bold">hot spare</dt>
<dd>Hot spare provides the ability
to have spare server hardware (such as an idle IXS) set aside as a backup
for the server hardware that is used by one or more active servers. If one
of the active servers has a server hardware failure, that server can quickly
be switched from the failed server hardware to the spare server hardware and
started again, drastically reducing the server downtime that is normally associated
with a server hardware failure. For more information see <a href="rzahqhotsparebetw.htm#rzahqhotsparebetw">Hot spare between server hardware</a>.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />

<dt class="bold">iSCSI initiator adapter</dt>
<dd>A host bus adapter
(HBA) that initiates iSCSI requests. iSCSI initiators issue SCSI commands
to request services from components, logical units, of a server known as a <span class="bold">target</span>. The iSCSI Initiator is the iSCSI HBA in the xSeries or BladeCenter server.</dd><img src="deltaend.gif" alt="End of change" /><img src="delta.gif" alt="Start of change" />
