4.2 EonStor U16U Subsystem Host Connection
4.2.1 SCSI Cable s
One SCSI cable (IFT-9270UHstCab) is provided with the ES U16U for host connection.
If a user wishes to use a second SCSI cable to connect the second host channel, a second
cable must be purchased independently. When purchasing SCSI-320 cables ensure that
they are of the highest quality and that a reputable manufacturer has produced them. To
ensure optimum ES U16U performance it is necessary to use proper SCSI-320, high
quality, durable SCSI cables. Failure to do so will result in downgraded performance.
4.2.2 Connecting the four channel ES U16U
The ES U16U RAID subsystem has two SCSI-320 connectors at the back of the
controller module. These connectors serve as interfaces to CH0 and CH1 and allow the
subsystem to be connected to external host computers. CH0 and CH1 can either be
connected to the same host computer (see
Figure 4-1
) or two different host computers
(see
Figure 4-2
).
