FC SAN
Fibre Channel Storage Area Network. Basically, a storage device that is purposely built
as a robust block-level networked storage device. Suitable for data centers. Limitations
includes, large investment ($60K USD to $120K USD), Fibre Channel protocol expertise,
requires integration from multiple vendors, and requires double the equipment for
disaster recovery and redundancy.
FCIP
Fibre Channel over TCP/IP. FCIP is a TCP/IP-based tunneling protocol for connecting
geographically distributed Fibre Channel SANs transparently to both Fibre Channel and
IP.
Firewall
A set of related programs, located at a network gateway server that protects the resources
of a private network from users from other networks.
Frame
A frame is a single data packet that is transmitted across a network.
FTP
An application protocol commonly used to transfer Web page files from their creator to
the computer that acts as their server for everyone on the Internet. Also commonly used
to download programs and other files to your computer from other servers.
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.
