Example SCSI Configurations
IntraServer’s ITI-8000 Series adapters greatly increase the configuration
flexibility for SCSI while allowing increased performance two to four times
over previous generation products. LVD technology allows multi-drop
cables up to 12 meters, while operating at 80MB/sec.
To maximize the performance of the ITI-8000 Series adapter, the following
general rules must be followed.
•
Ultra2/LVD devices must be connected only to the Ultra2/LVD
connectors.
•
If Ultra/SE devices must be connected to the adapter, put them all
on one bus, SE drives will cause the bus they are on to run at Ultra
speeds, and limit the bus performance to 40MB/sec.
•
The maximum cable length, end to end, of the LVD bus must be 12
meters or less for multi-drop connections
•
The maximum cable length, end to end, of any bus running in SE
mode must be 1.5 meters or less
•
Use the LVD cable supplied in your kit to attach LVD devices to
the LVD/SE connector on the card
•
The end of the SCSI bus MUST provide LVD termination.
Refer to the cabling examples below to correctly configure your adapter.
