RAID RAID stands for Redundant Array of Independent Disks,
which is a set of methods for storing data on multiple disks.
Striping increases logical capacity. Mirroring increases
performance and reliability. Various parity schemes increase
reliability. RAID schemes can be implemented in hardware
or software.
RPC RPC stands for Remote Procedure Call.
SAN SAN stands for Storage Area Network, which consists of
multiple storage units and servers connected by networking
topology.
SCSI SCSI stands for Small Computer System Interface. The
original SCSI specification was a hardware bus specification
and a packet-oriented protocol specification for
communicating on that bus. SCSI over Fibre Channel uses
the packet-oriented protocol to communicate with storage
devices on the Fibre Channel.
SP SP stands for Service Provider.
SPX See IPX.
Static load balancing Static load balancing is a software feature that improves
system performance by balancing device access between
multiple QLA2xxx adapters for maximum resource
efficiency. This is a feature in QLconfig.
Target device A target device is a storage device that is uniquely identified
by a WorldWide Name (WWN) and offers block disk storage
for one or more LUNs through one or more target ports.
Target port A target port is a Fibre Channel target that is uniquely
identified by a worldwide port name and provides an access
into the target device. As long as a device has only one port,
the worldwide port name can be the worldwide node name,
but it is not necessary. Many manufacturers make the
worldwide node name and the worldwide port names similar
to each other (the same number with a couple of bits
changed), but it is not necessary.
TCP TCP stands for Transmission Control Protocol, a network
transport layered combined with IP.
