Chapter 2 iSCSI Introduction and Glossary
2.1 What is iSCSI?
SCSI (Small Computer Standard Interface) is an ANSI standard parallel interface used by a computer
to link up with peripheral devices. As it offers faster transfer rates than other standard interfaces, it is
commonly used in workstations and servers as the interface of HDD and other storage devices.
A iSCSI (Internet SCSI) is a protocol that integrates SCSI protocol into TCP/IP packet in order to link
storage device with servers over a network. iSCSI is capable of providing high-effi ciency SANs (Storage
Area Networks) over standard IP network such as LAN, WAN or Internet.
Conventional SANs generally refer to the storage area networks under Fiber-Channel. Yet to response
to the effects of iSCSI, currently SANs are divided into FC-SANs and IP-SANs. IP-SAN uses iSCSI
transfer protocol to add storage capacity unlimitedly to a server over the Internet, regarded as a real
storage network system.
The storage capacity of IP-SANs can be expanded using various storage systems from various vendors.
Furthermore, under SANs, any network types (such as Ethernet, High Ethernet or Fast Ethernet) and
various operation systems (such as Microsoft Windows, Linux, Solaris and etc) can be supported. IP-
SANs also provides the mechanisms for security, data duplication, multi-channel, high-effi ciency and etc.
2.2 Using iSCSI
A connection using storage protocol such as iSCSI requires “two ends”, a “Initiator” and a “target”. In the
iSCSI fi eld, they are called “iSCSI initiator” and “iSCSI target”.
iSCSI initiator asks for operation from all SCSI, for example, read and write. iSCSI usually locates in the
Host side or sever side.
On the other hand, iSCSI target refers to the storage equipments or the devices used for managing or
allocating capacity. It is a device for executing SCSI commands. An iSCSI target can be a disk, tape or
disk array.
