Firmware Update
The firmware, BIOS and StorCon program of the Intel RAID Controller SRCMR are stored in
Flash-RAM which is part of the Intel RAID Controller SRCMR hardware. In contrast to EPROMs,
Flash-RAMs can be reprogrammed many times without the complicated UV-light erasing
procedure. Firmware, BIOS and StorCon are part of the SRC_PFW file. The file has an extension
(for example, SRC_PFW.009) which indicates the version stepping.
✏
NOTE
This option is not available when StorCon is accessing Intel RAID Controller SRCMR remotely.
Intelligent Fault Bus
Intelligent Fault Bus is an older subsystem standard, which is no longer used in modern subsystems
or backplanes. Intel RAID Controller SRCMR’s Ultra/Wide Disk Array Controllers were the last
Intel RAID Controller SRCMRs supporting this standard, sometimes also called “DEC Fault Bus”.
Today’s modern subsystems are either using SAF-TE (SCSI Accessed Fault Tolerant Enclosures)
or SES (SCSI Enclosure Services) as communication links to the controller. These intelligent
subsystems are normally built on so-called backplanes, which host hard disks equipped with SCA
connectors (Single Connector Attachment). The backplane has dedicated electronics with
microprocessor and firmware which allows intelligent communication between the
subsystem/backplane and the Intel RAID Controller SRCMR. Through this channel the subsystem
can report its temperature and the power supply status to the Intel RAID Controller SRCMR. The
major objective of SAF-TE or SES is auto hot plug. In contrast to hot plug, auto hot plug allows a
