SAN
Storage area network. Multiple storage
units (disk drives) and servers connected
by networking topology.
SCSI
Small computer system interface. A
high-speed interface used to connect
devices, such as hard drives, CD drives,
printers, and scanners, to a computer. The
SCSI can connect many devices using a
single controller. Each device is accessed
by an individual identification number on
the SCSI controller bus.
SerDes
Serializer/deserializer. A pair of functional
blocks commonly used in high-speed
communications to compensate for limited
input/output. These blocks convert data
between serial data and parallel interfaces
in each direction.

SR-IOV
Single root input/output virtualization.
storage area network
See SAN.
target
The storage-device endpoint of a SCSI
session. Initiators request data from
targets. Targets are typically disk-drives,
tape-drives, or other media devices.
Typically a SCSI peripheral device is the
target but an adapter may, in some cases,
be a target. A target can contain many
LUNs.
A target is a device that responds to a
requested by an initiator (the host system).
Peripherals are targets, but for some
commands (for example, a SCSI COPY
command), the peripheral may act as an
initiator.
target binding
The process in which the adapter driver
binds a target ID using a target’s world-
wide port name (WWPN) or port ID. This
binding enables the target ID to always
connect to the WWPN or port ID across
reboots regardless of SAN reconfiguration.
TCP
Transmission control protocol. A set of
rules to send data in packets over the
Internet protocol.
TLV
Type-length-value. Optional information
that may be encoded as an element inside
of the protocol. The type and length fields
re fixed in size (typically 1—4 bytes), and
the value field is of variable size. These
fields are used as follows:
 Type—A numeric code that indicates
the kind of field that this part of the
message represents.
 Length—The size of the value field
(typically in bytes).
 Value—Variable-sized set of bytes that
contains data for this part of the
message.
