DSL.
Device Synchronization Layer. The DSL
controls and participates in device I/O request
processing on the IOPs.
enable.
Manually add a component to the active
Endurance server configuration. Components are
enabled using an Endurance Manager or a
MTCCONS command.
Endurance Manager.
A user-level server
management application for the Endurance server.
This Endurance application provides both a
Windows-based graphical user interface (GUI)
and a command prompt interface.
Endurance sector.
A management sector on
the mirror set disks that is used to track
information about the mirror set. The Endurance
sector is located on the administrative portion of
the disks (track 1) and is not part of the data portion
of the disks.
Endurance server.
A fault tolerant, disaster
tolerant server that consists of systems configured
with Marathon’s patented fault tolerant
technology.
Endurance System Interconnect.
See.
ESI
.
ESI.
Endurance System Interconnect. The
collection of all path components in a CE to IOP
interconnect, including all MICs and MIC cables.
failout.
See
constant computing
.
failure.
An observable malfunction of an
Endurance server component.
fault management.
The process of detecting a
failure, diagnosing it, and continuing to process,
using either a failout or failover process. In
addition, this may include repairing one or more
component(s) and returning them to service in the
active Endurance server configuration.
faulted.
A state that indicates an Endurance
component has failed and has been removed from
the active Endurance server configuration. This
state indicates one or more failures were attributed
to the component. A component remains faulted
until it is manually repaired and enabled, using an
Endurance Manager or MTCCONS command.
field replaceable unit.
See
FRU
.
FPGA.
Field Programmable Gate Array. Each
MIC uses FPGA code that can be updated using
the MTCFLASH Utility.
FRU.
Field Replaceable Unit. An Endurance
server hardware component that can be replaced
on site.
I/O Processor.
See
IOP
.
IL.
IOP Link. A private, dedicated Ethernet path
between the IOPs. This path is the data path for
mirror copies and inter-IOP communication.
input devices.
The keyboard and pointer for
your Endurance server.
interconnect.
The physical cable that connects
an IOP to a CE or an IOP to the other IOP.
IOP.
I/O Processor. The systems in an Endurance
server that provide I/O resources, including I/O
processing, data storage, and network
connectivity.
