Gateway

A combination of hardware and software that links two different types of networks.

Gigabyte

A Gigabyte is one trillion Bytes of data. Most hard disk drive manufacturers follow the
metric conventions of Kilobyte, Megabyte, and Gigabytes for specifying the drive
capacity on their label and specifications (for example, 1000 B =1 KB, 1000 KB=1 MB
and 1000 MB=1 GB) instead of the 1024 convention.
For example, given a manufacturer-specified 18.4 GB hard disk, the actual capacity
reported by the disk is 17930455 KB = 17930455 *1024 = 18360785920 Bytes. This, if
converted to metric convention, results in the specified 18.36 GB capacity rounded up.
Thus, the actual capacity of the 18.4GB drive is displayed as 17.1 GB.

Group

A group is a number of users that are bunched together. Having a group makes it easier to
assign a set of rules that are common to a set of users. Common groups can be
Accounting, Sales, Marketing, and so on.

High Availability

High Availability or HA is a term used in this document to describe the system design
protocol and associated implementation that ensures a certain absolute degree of
operational continuity during a given measurement period.
This Feature allows two StorTrends iTX (version 2.6 and newer) SAN Heads to be
grouped as highly-available cluster nodes for Microsoft initiators. This, together with
MPIO DSM for StorTrends will allow deploying solutions with extreme fault tolerance
and total availability. This solution provides protection against disk failures, path failures
and node failures. In the event of Node failure, the Failover action is automatic and
seamless. When the Failed node comes up, it is detected by the stack and is synchronized
quickly to bring back redundancy to the setup. Synchronization is very efficient and
ensures that only out-of-sync data is resynced.

Host

A computer that is connected to a TCP/IP network, including the Internet. Each host has
a unique IP address.

HTTP

An application protocol that is the set of rules for exchanging files (text, graphic images,
sound, video, and other multimedia files) on the World Wide Web.

iFCP

Internet Fibre Channel Protocol. iFCP is a TCP/IP-based protocol for interconnecting
Fibre Channel storage devices or Fibre Channel SANs using an IP infrastructure to
complement or replace Fibre Channel switching and routing elements.

Internet

A global wide area network connecting millions of computers.
