Other Configurations
There are many possible combinations of controllers and cabling schemes when
configuring the CR8e subsystem enclosures. The sample configurations in the
previous sections provide the basic configurations. However, the CR8e is based on
an open-architecture expandable subsystem and allows for customization to fit
your current or future needs.
Some other possible schemes within SCSI bus length limitations for both Ultra
Wide SCSI and Fast Wide SCSI are:
■A 3-channel AM RAID Controller where two channels connect to a
dual-bus cabinet with two single-bus cabinets (Fast Wide). The third
channel of the controller can be connected to another Single-Bus enclosure
(Ultra Wide or Fast Wide).
■A 3-channel AM RAID Controller with a Single-Bus enclosure connected
to each channel (Ultra Wide or Fast Wide).
■A 3-channel AM RAID Controller with two Single-Bus enclosures
connected to each channel (Fast Wide).
■A 3-channel AM RAID Controller with two Single-Bus enclosures
connected to two channels and a dual-bus cabinet connected to the third
channel (Fast Wide).
■A 3-channel AM RAID Controller with four Single-Bus enclosures
connected to two channels and a dual-bus cabinet connected to the third
channel (Fast Wide).
■A 2-channel AM RAID Controller with two Single-Bus enclosures
connected to each channel (Ultra Wide or Fast Wide).
■A 2-channel AM RAID Controller with one Single-Bus enclosure
connected to each channel (Ultra Wide or Fast Wide).
NOTE: For additional configuration options while operating under the Ultra
Wide SCSI mode, refer to the nStor Feature Card User’s Guide.
