gateway

gateway. (1) A device used to convert the message protocol of one network to that of

another. (2) A short code sequence that accomplishes the transition to privileged mode

for legitimate calls to callable procedures. See also far gateway

GB. See gigabyte (GB).

GCSC. See Global Customer Support Center (GCSC).

general-purpose register (GPR). One of a small number of undedicated high-speed

memory locations in a processor.

generic process. A process created and managed by the 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).

G4SA. See Gigabit Ethernet 4-port ServerNet adapter (G4SA).

Gigabit Ethernet ServerNet adapter (GESA). A single-port ServerNet adapter that

provides 1000 megabits/second (Mbps) data transfer rates between HP NonStop™

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)

•

3865 GESA-F (T523572): a single-port fiber version compliant with the 1000

Base-SX standard (802.z)

Gigabit Ethernet 4-port ServerNet adapter (G4SA). A multiport ServerNet adapter that

provides 1000 megabits/second (Mbps) data transfer rates between HP NonStop™

systems and Ethernet LANs. The G4SA is installed in slots 1, 2, 3, 4, and 5 of an I/O

adapter module (IOAM). There are two IOAMs in an I/O adapter module (IOAM)

enclosure, so a total of 10 G4SAs can be installed in an enclosure. The G4SA is the

only LAN adapter supported for the IOAM enclosure. Although the G4SA implements

the Ethernet 4 ServerNet adapter (E4SA)

, Fast Ethernet ServerNet adapter (FESA),

and the Gigabit Ethernet ServerNet adapter (GESA)

functions, it cannot be installed in

an HP NonStop™ S-series enclosure.

gigabyte (GB). A unit of measurement equal to 1,073,741,824 bytes (1024 megabytes).
