for transferring files to and from servers.
Use of an FTP site requires a user ID and
possibly a password.
full capacity expansion
A feature that increases the initial capacity
of Model L22, L23, L52, and L53 frames.
Models L22 and L23 increase from 58 to
199 or 260 cartridge slots for 3592 tape
cartridges. Models L52 and L53 increase
from 64 to 219 or 287 cartridge slots for
LTO Ultrium tape cartridges.
full duplex
Simultaneous transmission and reception
of data between two nodes of a network.
G
See gigabyte.
GB
See gigabit.
Gb
Gigabits per second. One gigabit equals
Gbps
1 000 000 000 bits.
get (1) In library operation, the act of a
cartridge gripper retrieving a tape
cartridge from a storage slot, drive, or
I/O station.
(2) In Simple Network Management
Protocol (SNMP), a request for
information about the library that the
operator issues through a monitoring
server and which is transmitted by SNMP.
get-response
The information that is provided in
response to an SNMP get.
GiB One gibibyte (GiB) = 1,073,741,824 bytes.

head See drive head.
heat output
The amount of heat (in kBtu/hr) that the
TS3500 Tape Library dissipates during
normal operation.
hertz (Hz)
A unit of frequency equal to cycle per
second.
heterogeneous
Of unlike kind.
hex, hexadecimal
(1) Pertaining to a selection, choice, or
condition that has 16 possible different
values or states.
(2) Pertaining to a fixed-radix numeration
system, with radix of 16.
(3) Pertaining to a system of numbers to
the base 16; hexadecimal digits range
from 0 through 9 and A through F, where
A represents 10 and F represents 15.
high availability (HA)
A product that contains redundancy to
continue work in case of a set of (but not
all possible) failures. A library that is HA
contains two separate accessors.
High Availability Clustered Multiprocessing
(HACMP)
An IBM AIX solution that automatically
detects system or network failures and
eliminates a single point of failure by
managing failover to a recovery processor.
High availability clustering refers to the
linking of two or more computers, one of
which can provide operation if the other
one fails.
High Density Capacity on Demand
Applicable only to expansion frame
Models S24 and S54, a feature that adds
licensed capacity to the library.
High density frame
An expansion frame that contains HD
slots.
High density slot
A four-deep or five-deep container for
cartridges in an HD frame.
High Voltage Differential (HVD)
A logic signaling system that enables data
