Connecting Ports to Hosts
By default, channels 1 and 3 (the upper middle SCSI port and lower left SCSI port on
the I/O module) are host channels. The array can be connected to a host in one of the
following ways:
■
By means of an Ultra160 LVD-compliant HBA installed in a host
■
By means of a qualified and supported onboard single-ended server-embedded SCSI
controller
Connect the array to one or two hosts with SCSI cables. Refer to the
SANnet II 200
SCSI Array Release Notes
for a list of the supported cables.
4.9.1
Connecting a SANnet II 200 SCSI RAID Array
The SCSI specification states that the maximum bus length for Ultra3 SCSI is 25
meters (82 feet) for point-to-point connections. The SANnet II 200 RAID array uses a
point-to-point implementation. Each channel connector is on a separate physical SCSI
bus.
Taking into account the internal bus length of .5 meters (1.64 feet) and the internal
SCSI bus length of the host, the maximum SCSI cable length to each channel
connector could conceivably be around 24 meters (72.8 feet) when connected to an
Ultra3 host adapter. However, the longest Ultra3 cable qualified by Dot Hill is 10
meters (32.8 feet) in length.
When connected to single-ended host adapters, the longest support bus length per
connector is 1.5 meters (4.9 feet).
