Glossary
will perform the iFCP/iSCSI encapsulation. The SAN Router’s
internal IP address is used by the iFCP/iSCSI port to receive this
storage traffic from the internal network. This traffic is then
re-addressed and re-encapsulated into an iFCP/iSCSI connection that
traverses the external network. This address is configured through
the
FC/Ethernet Port Configuration
dialog box in the Element Manager.
Internet Fibre Channel
Protocol (iFCP)
A gateway-to-gateway protocol for providing Fibre Channel fabric
services to Fibre Channel end devices over a TCP/IP network. The
iFCP protocol uses TCP for congestion control, error detection, and
recovery.
Internet protocol
IP. Network layer for the transmission control protocol/Internet
protocol (TCP/IP) protocol used on Ethernet networks. IP provides
packet routing, fragmentation, and reassembly through the data link
layer
(D)
.
Internet protocol
address
IP address. Unique string of numbers (in the format xxx.xxx.xxx.xxx)
that identifies a device on a network.
internetworked SAN
(iSAN)
An internetworked storage area network (iSAN) is a collection of one
or more fabrics interconnected using one or more SAN routers,
where typically, at least one fabric is in a distant location outside the
metro area. An iSAN is characterized by high latency and low
bandwidth ISLs (T1, T3, OC3, etc.) such as those found in wide area
networks. An iSAN has at least two SAN routers that are
interconnected using iFCP connections. An iSAN is also a collection
of two or more mSANs. SAN routing done within an iSAN is referred
to as iSAN Routing or SAN Routing over distance. An iSAN could
also be deployed entirely within a data center to scale beyond the
metrics of an mSAN.
internetworked SAN
routing
Internetworked storage area network (iSAN) routing is routing
across an IP network to a remote mSAN interconnected by SAN
Routers.
Internet Small
Computer Interface
(iSCSI) Protocol
The iSCSI protocol defines a means of transporting SCSI packets over
TCP/IP, providing for an interoperable solution which can take
advantage of existing internet infrastructure, internet management
facilities and address distance limitations.
interoperability
Ability to communicate, execute programs, or transfer data between
various functional units over a network.
