computer (such as a server that hosts Exchange or SQL Server) and a target
device (such as the HP All-in-One Storage System). By carrying SCSI commands
over IP networks, iSCSI is used to facilitate data transfers over intranets and to
manage storage over long distances.
HDD Hard disk drive.
iLO Integrated Lights-Out.
LAN Local area network. A communications infrastructure designed to use dedicated
wiring over a limited distance (typically a diameter of less than five kilometers)
to connect to a large number of intercommunicating nodes. Ethernet and token
ring are the two most popular LAN technologies. (SNIA)
logical disk A logical disk contains one or more volumes and spans multiple hard drives in
an array. RAID configuration of storage is performed at the logical disk level.
Also known as a LUN.
LUN Logical unit number.
mount point A host's file system path or directory name where a host volume (device) is
accessed.
NAS Network attached storage.
NFS Network file system. The protocol used in most UNIX environments to share
folders or mounts.
NIC Network interface card. A device that handles communication between a device
and other devices on a network.
SAN Storage area network. A network of storage devices available to one or more
servers.
SAS Serial Attached SCSI.
SATA Serial Advanced Technology Attachment.
SNMP Simple Network Management Protocol. A widely used network monitoring and
control protocol. Data is passed from SNMP agents, which are hardware and/or
software processes reporting activity in each network device (hub, router, bridge,
and so on) to the workstation console used to oversee the network. The agents
return information contained in a MIB (Management Information Base), which
is a data structure that defines what is obtainable from the device and what can
be controlled (turned off, on, and so on).
volume Volume on disk. An accessible storage area on disk, either physical or virtual.
volume mapping The process by which volume permissions (read only, read/write, or none) and
LUNs are assigned to a host port.
