J.4.3.2 Menu Advanced Setup: Configure Controller, Firmware Update
The firmware, the BIOS and the ICPCON program of the ICP Controller are stored in a Flash-
RAM which is part of the ICP Controller hardware. In contrast to EPROMs, Flash-RAMs can
be re-programmed many times and without the complicated UV-light erasing procedure.
Firmware, BIOS and ICPCON are part of the
GDT_RPFW
file. The file has an extension (e.g.
GDT_RPFW.009) which indicates the version stepping. The latest version of the this file can
be downloaded from our Website (
www.icp-vortex.com) .
This menu option is not available when ICPCON is accessing the ICP Controller remotely.
J.4.3.3 Menu Advanced Setup: Configure Controller, Intelligent Fault Bus
Intelligent Fault Bus is an older subsystem standard, which is no longer used in modern
subsystems or backplanes. ICP’s Ultra/Wide Disk Array Controllers were the last ICP Con-
trollers supporting this, sometimes also called ”DEC™ Fault Bus”.
Today’s modern subsystems are either using SAF-TE (SCSI Accessed Fault Tolerant Enclo-
sures) or SES (SCSI Enclosure Services) as communication links to the controller. These
intelligent subsystems are normally build on so-called backplanes, which host hard disks
which are equipped with SCA connectors (Single Connector Attachments). The backplane
has a dedicated electronics with microprocessor and firmware which allows an intelligent
communication between the subsystem/backplane and the ICP Controller. Through this
channel the subsystem can for example report its temperature and the power supply status
to the ICP Controller. The major objective of SAF-TE or SES is to provide the Auto Hot Plug.
In contrast to the Hot Plug, a defective drive is simply pulled out the subsystem and the
replacement unit is plugged in again. Both, the ICP Controller and the subsystem control
this process so that problems on the SCSI/FC-AL bus are eliminated and the rebuild of the
missing data is initiated fully automatically. No further user interaction is necessary.
A unique and special feature of ICP Controllers is the following:
J.4.3.4 Menu Advanced Setup: Conf. Controller, Non-Intelligent Enclosures
Since SAF-TE or SES subsystems are pretty cost intensive, ICP has integrated a special
functionality which can control up to 16 non-intelligent enclosures with up to 15 hard disk,
each, and provides the Auto-Hot-Plug. It is clearly up to the user’s responsibility to use
components (e.g., disk shuttles), which are really hot pluggable.
