BER Bit error rate. The rate at which bits are expected to be received in error.
Expressed as the ratio of error bits to total bits transmitted.
See also error.
BISR Built-in self-repair.
BIST Built-in self-test.
bit synchroniza- The condition in which a receiver is delivering retimed serial data at the
tion required bit error rate.
blind-mate con- A two-way connector used in some HP StorageWorks switches to provide a
nector connection between the motherboard and the power supply.
block As it applies to Fibre Channel technology, upper-level application data that
is transferred in a single sequence.
boot code Software that initializes the system environment during the early phase of the
boot-up process. For example, boot code might determine the amount of
available memory and how to access it.
boot flash Flash (temporary) memory that stores the boot code.
bport Back-end port of the ASIC.
broadcast The transmission of data from a single source to all devices in the fabric,
regardless of zoning.

buffer-to-buffer Management of the frame transmission rate in either a point-to-point topology or
flow control in an arbitrated loop.

bypass circuitry Circuits that automatically remove a device from the data path when valid
signals are dropped.
CA Certificate authority. A trusted organization that issues digital certificates.

CAM Content-addressable memory. A memory chip in which each bit position can be
compared. In regular dynamic RAM (DRAM) and static RAM (SRAM) chips,
the contents are addressed by bit location and then transferred to the CPU for
comparison. In CAM chips, the content is compared in each bit cell, allowing
for very fast table lookups. Since the entire chip is compared, the data content
can often be stored randomly without regard to an addressing scheme, which
would otherwise be required. CAM chips are considerably smaller in storage
capacity than regular memory chips. Also called associative storage.
CAN Campus area network. A network comprising a limited area but not just one
building.
See also LAN, MAN, and WAN.
cascade Two or more interconnected Fibre Channel switches. HP StorageWorks 1 GB
and greater switches can be cascaded up to 239 switches, with a recommended
maximum of seven interswitch links (no path longer than eight switches).
