NEO 200s/400s User Guide
Software initiators are readily available for most host operating systems. Hardware
initiators are not widely used, although they may be useful in very high performance
applications or if 10 Gigabit Ethernet support is required.
Internet
A global network of networks used to exchange information using the TCP/IP protocol. It
allows for electronic mail and the accessing ad retrieval of information from remote sources.
I/O (Input/Output)
The operation of transferring data to or from a device, typically through an interface
protocol like CIFS, NFS, or HTTP.
IP
Short for Internet Protocol. The unique 32-bit value that identifies the location of the server.
This address consists of a network address, optional subnetwork address, and host address.
It displays as four addresses ranging from 1 to 255 separated by periods.
IQN
Short for iSCSI Qualified Name. A name format used in the iSCSI protocol.Initiators and
targets have IP addresses, just like any other network entity. They are also identified using
an iSCSI name, called the iSCSI Qualified Name (IQN). The IQN should be unique
worldwide. It is made up of a number of components, specifying the date, identifying the
vendor in reverse format, and then uniquely identifying the initiator or target. An example
of an IQN is:
iqn.2001-04.com.example:storage:diskarray-sn-123456789
Since these IQNs are rather unwieldy, initiators and targets also use short, user friendly
names (sometimes called alias names or just aliases).
iSCSI
Short for Internet SCSI. iSCSI is an IP-based storage networking standard for linking data
storage facilities. iSCSI is a standard that defines the encapsulation of SCSI packets in
TCP and then routing it using IP. It allows block-level storage data to be transported over
widely used IP networks.
iSNS Server
Short for Internet Storage Name Service Server. A protocol enabling the automatic
discovery, configuration, and management of iSCSI devices on a TCP/IP network.
Kerberos
A secure method for authenticating a request for a service used by ADS. Kerberos lets a
user request an encrypted “ticket” from an authentication process that can then be used to
request a service from a server. The user credentials are always encrypted before they are
transmitted over the network.
In Windows 2000/XP, the domain controller is the Kerberos server. The Kerberos key
distribution center (KDC) and the origin of group policies are applied to the domain.
LAN
Short for Local Area Network. A network connecting computers in a relatively small area
such as a building.
