file transfer protocol (FTP)
In the Guardian environment, disk file names include a node name, volume name,
subvolume name, and file identifier; for example, \NODE.$DISK.SUBVOL.MYFILE.
In the Open System Services (OSS) environment, a file is identified by a pathname; for
example, /usr/john/workfile. See also filename
.
file transfer protocol (FTP). (1) The Internet-standard, high-level protocol for transferring
files from one machine to another. The server side requires the client to supply a logon
identifier and password before it honors requests. FTP makes no assumptions about
the file-naming structure of the source and destination systems, and it allows the file
names of each system to be represented in the vernacular. (2) The application used to
send complete files over Transmission Control Protocol/Internet Protocol (TCP/IP)
services.
firmware. Code in memory that is necessary for the power-up initialization and
communication with a host or device. The software for components of the ServerNet
architecture (for example, an adapter) is called firmware. Some firmware for ServerNet
components is downloaded when the system or component is loaded.
flash PROM. A type of programmable read-only memory (PROM) that is electrically
reprogrammable.
FRU. See field-replaceable unit (FRU)
.
frame. (1) An assembly of sheet-metal parts that is an integral part of an enclosure and
might contain peripherals or a chassis, depending on the type of enclosure. The frame
enables the enclosures to be stacked and has provisions for routing and securing
cables. The frame of an enclosure has dimensions that conform to an industry-
standard 19-inch rack. (2) A unit of transmission in some data communications
protocols, usually containing header, data, and checksum fields. (3) In NonStop
S-series processors, a 4096-byte unit of physical memory; also called a physical page.
FTP. See file transfer protocol (FTP).
generic process. A process created and managed by the NonStop Kernel subsystem; also
known as a system managed process. A common characteristic of a generic process is
persistence.
GESA. See Gigabit Ethernet ServerNet adapter (GESA).
Gigabit Ethernet ServerNet adapter (GESA). A single-port ServerNet adapter that
provides 1000 megabits/second (Mbps) data transfer rates between NonStop S-series
systems and Ethernet LANs. A GESA can be directly installed in slots 51 through 54 of
an I/O enclosure and slots 53 and 54 of a processor enclosure.
Two versions of the GESA are available:
•
3865 GESA-C (T523572): a single-port copper version compliant with the 1000
Base-T standard (802.3ab)
