logic gates, inside high-density field- programmable gate arrays (FPGAs) or application-
specific integrated circuits (ASICs).
Host
A computer connected to storage; typically a server running applications or providing
services that access and consume storage.

Input/Output (I/O)
The process of moving data between the main memory of a computer system and an
external device or interface such as a storage device, display, printer, or network connected
to other computer systems. I/O is a collective term for reading or moving data into a
computer system’s memory, and writing, or moving data from a computer system’s memory
to another location.
Initiator
SCSI device (usually a host system) that requests an operation to be performed by another
SCSI device, the target.
IOPS
Input/Output Per Second. It is the number of inputs and outputs or read/writes per second.
iSCSI
iSCSI is a protocol that enables the transmission of block-level SCSI data between storage
devices and computers over a standard IP network. iSCSI combines Ethernet-based IP
networking with the SCSI command set, the core command set used in all storage
configurations.
iSCSI Client
A logical entity, typically a host, which includes at least one iSCSI Initiator.
