Glossary
high speed serial data
connector
A 20-pin serial connector type that provides connectivity to an
ES-1000 Switch GBIC. Contrast with DB-9 connector.
host bus adapter A logic card that provides a link between a server and storage
subsystem, and that integrates the operating systems and I/O
protocols of both devices to ensure interoperability.
H_Port See hub port.
HSSDC See high speed serial data connector.
hub A non intelligent device that connects Ethernet or Fibre Channel
nodes into a logical loop by using a physical star topology.
hub port An arbitrated loop port that provides FC-AL device connectivity to
the ES-1000 Switch. H_Ports are not assigned port addresses and
provide physical connectivity only. Contrast with fabric loop port.
I
IML See initial machine load.
inband management Management of a director or switch through a Fibre Channel or
FICON port connection to a management server. Contrast with
out-of-band management.
initial machine load A software operation that reloads director or switch firmware and
resets the Ethernet LAN interface. An IML is typically performed by
pressingthe IML button at the director or switch front panel. An IML
is functionally equivalent to an IPL.
initial program load A software operation that reloads director or switch firmware and
resets the Ethernet LAN interface. An IPL is typically performed
through a menu option at the directororswitchElementManager
application. An IPL is functionally equivalent to an IML.
Internet protocol
address
A uniquestring of numbers (in the format XXX.XXX.XXX.XXX)that
identifies a device on a TCP/IP network.
interswitch link A physical expansion port (E_Port) connection between two fabric
elements (directors or switches) in a multiswitch fabric.
