Fibre Channel over See FCoE.
Ethernet
iSCSI Internet small computer system interface. Transmits native SCSI over the TCP/IP
stack. In a system supporting iSCSI, a user or software application issues a
command to store or retrieve data on a SCSI storage device. The request is
processed by the operating system and is converted to one or more SCSI
commands that are then passed to software or to a card. The command and
data are encapsulated by representing them as a serial string of bytes proceeded
by iSCSI headers. The encapsulated data is then passed to a TCP/IP layer that
breaks it into packets suitable for transfer over the network. If required, the
encapsulated data can also be encrypted for transfer over an insecure network.
LUN Logical unit number. Representation of a logical address on a peripheral device
or array of devices.
multipath routing The routing technique of leveraging multiple alternative paths through a network,
which can yield a variety of benefits such as fault tolerance, increased bandwidth,
or improved security.
path A path to a device is a combination of an adapter port instance and a target
port as distinct from internal paths in the fabric network. A fabric network appears
to the operating system as an opaque network between the adapter (initiator)
and the target.
Because a path is a combination of an adapter and a target port, it is distinct
from another path if it is accessed through a different adapter or it is accessing
a different target port. Consequently, when switching from one path to another,
the driver might be selecting a different adapter (initiator), a different target port,
or both.
This is important to the driver when selecting the proper method of failover
notification. It can make a difference to the target device, which might have to
take different actions when receiving retries of the request from another initiator
or on a different port.
Replication See
Solutions Manager
RSM Replication Solutions Manager. HP StorageWorks Replication Solutions Manager
Software provides a powerfully simple graphical user interface (GUI) to create,
manage and configure remote/local replication on the entire HP StorageWorks
Enterprise Virtual Array (EVA) family. The Replication Solutions Manager Software
integrates with HP Business Copy EVA Software and HP Continuous Access EVA
Software for local and remote replication. This results in a unique, cost effective
disaster recovery solution, with less effort to configure offering value to IT and
its resources. Automated scripts, wizards, Interactive Replication Topology Viewer
reduce complexity and provide greater flexibility of executing tasks.
SAN Storage Area Network. A network of storage devices and the initiators that store
and retrieve information on those devices, including the communication
infrastructure.
secure shell See SSH.
SSH Secure shell. Protocol that secures connections to the switch for the command
line interface.
