NAA
Network Address Authority, a naming format defined by the INCITS T11 Fibre Channel protocols
[FC-FS]. The following table summarizes the current protocols and their naming formats.

This identifier format is used by the Fibre Channel and SAS SCSI transport protocols.
ISCSI
iSCSI
uses a unique name to identify an iSCSI node, either target or initiator. This
name used as a way to universally identify the node. iSCSI names are formatted
in two different ways.
- IQN
- EUI
iSCSI Qualified Name (IQN) Format
The iSCSI
qualified name format is defined in [RFC3720]
Example:
iqn.2001-04.com.example.iscsi:SRV1-85412701
Format:
iqn.yyyy-mm.naming-authority:unique
name
"iqn" specifies the use of the
iSCSI qualified name as the authority.
"YYYY-MM" is the year and month on
which the naming authority acquired the domain name
used in this iSCSI name.
"naming-authority " is usually reverse
syntax of the Internet domain name of the naming authority. The name in our
example indicates that the example.com domain name was registered in April of
2001, and iscsi is a subdomain, maintained by example.com.
“unique name” is any name you want to use,
for example, the name of your host. The naming authority must make sure that
any names assigned following the colon are unique, such as:
■
|
|
■
|
EUI Formatting
The EUI format takes
the form eui.16
hex digits.
The 16-hexadecimal digits are text
representations of a 64-bit number of an IEEE EUI (extended unique identifier)
format.
The top 24 bits are
a company ID that IEEE registers with a particular company. The lower 40 bits
are assigned by the entity holding that company ID and must be unique.
The details of constructing
EUI-64 identifiers are specified by the IEEE Registration Authority (see [EUI64]).
iSCSI Alias
The iSCSI alias is a UTF-8 text string that may be used as an additional descriptive name that can be assigned to an initiator or target, that is independent of the name, and does not have to be unique.
iSCSI Alias
The iSCSI alias is a UTF-8 text string that may be used as an additional descriptive name that can be assigned to an initiator or target, that is independent of the name, and does not have to be unique.
Since it is not
unique, the alias must be used in a purely informational way. It may not be
used to specify a target at login, or used during authentication.
The alias
must NOT be used to identify, address, or authenticate initiators and targets.
