Read Only Memory. Memory from which information can be read but not
changed. The contents of ROM are not erased when the computer is
turned off.
Storage Area Network.
SCSI Configured AutoMatically. A method to automatically allocate SCSI
IDs using software when SCAM compliant SCSI devices are attached.
A device driver feature that lets the host adapter modify a transfer data
pointer so that a single host adapter transfer can access many segments
of memory. This minimizes interrupts and transfer overhead.
SCSI Command Block.
Small Computer System Interface. A specification for a high-performance
peripheral bus and command set. The original standard is referred to as
SCSI-1.
The current SCSI specification which adds features to the original
SCSI-1 standard.
A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI
bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15
for Wide SCSI). The host adapter usually gets ID 7 giving it priority to
control the bus.
A term referring to one of the FC "building blocks", composed of one or
more related frames for a single operation.
Scatter Gather List.
SubNetwork Access Protocol.
One of the ways data is transferred over the SCSI bus. Transfers are
clocked with fixed frequency pulses. This is faster than asynchronous
data transfer. Synchronous data transfers are negotiated between the
SCSI host adapter and each SCSI device.
Controls the low level POST (Power On Self Test), and basic operation
of the CPU and computer system.
Target ID.
The logical and/or physical arrangement of stations on a network.
