IP-SAN
Block-level Storage Area Networks over TCP/IP using the iSCSI
protocol.
iSCSI
Internet SCSI. An IP-based standard for connecting data storage
devices over a network and transferring data using SCSI commands
over IP networks. iSCSI enables a Storage Area Network to be
deployed in a Local Area Network.
iSNS
Internet Storage Name Service. A protocol that allows automated
discovery, management and configuration of iSCSI devices on a TCP/IP
network.
L
LAN
Local Area Network. A computer network that spans a relatively small
area, such as a single building or group of buildings.
Loopback address
Loopback address is a virtual address that means itself in network. In
case of IPv4 uses “127.0.0.1”, in case of IPv6 uses “::1”. Also “local
host” is used as the host name conventionally.
LU
Logical Unit
LUN
Logical Unit Number
LRU
Least Recently Used (LRU) — An algorithm where new items are placed
at the top of the cache and items at the bottom of the cache are
discarded when the cache grows past its size limit. Whenever an item is
accessed, it is pulled back to the top of the cache.
M
Middleware
Software that connects two otherwise separate applications. For
example, a middleware product can be used to link a database system
to a Web server. Using forms, users request data from the database;
then, based on the user's requests and profile, the Web server returns
dynamic Web pages to the user.
