•The MV U320-R or MV U320-RX communicates with your computer using an industry-standard SCSI interface. You must
have a compatible SCSI Host Adapter installed in your computer to work with the MV U320-R or MV U320-RX storage
system. Some computers have a built-in native SCSI port. Check your computer for availability.
•To maximize the Ultra320 interface of the MV U320-R or MV U320-RX, the SCSI host adapter in your computer should be
rated for Ultra320. Ultra160, Ultra2, and Ultra Wide SCSI rated host adapters will work but at a slower transfer rate.
•Make sure the host adaptor is installed correctly, and that the appropriate host adapter drivers are installed and functioning
properly, before connecting the MV U320-R or MV U320-RX to the host computer.
SCSC In/Out Connections
MV U320-R
The MV U320-R has a pair of SCSI 68-pin high density (68HD) connectors. This SCSI channel is compatible with Ultra320,
Ultra160, Ultra2, and other SCSI standards. HVD (High Voltage Differential) is not supported.
Host Connections
Use Ultra320-rated SCSI cables to connect each side of the SCSI channel to your host computer.
•Connect the Side A SCSI IN to the first SCSI channel of the host computer.
Terminator
Use an Ultra320-rated SCSI terminator to terminate the SCSI connection. Connect the terminator to SCSI OUT.

Rev. A Page 8
MV U320-RX
The U320-RX contains two RAID controllers (Side A and Side B). Each controller has a pair of SCSI high-density 68-pin connectors.
Each SCSI channel is compatible with Ultra320, Ultra160, Ultra2, and other SCSI standards. HVD (High Voltage Differential) is not
supported.
See the figure below for the SCSI configuration per Side A and Side B of the MV U320-RX.
Side A and Side B SCSI Connectors.
Host Connections
Use Ultra320-rated SCSI cables to connect each side of the SCSI channel to your host computer.
• Connect the Side A SCSI IN to the first SCSI channel of the host computer.
• Connect the Side B SCSI IN to the second SCSI channel of the host computer.

Daisy Chaining
MV U320-R
Multiple SCSI devices can be connected by a daisy chain, as indicated in the figure below.
Make the following connections:
• Run a SCSI cable from the SCSI IN connector of the MV U320-R to the SCSI connector of the host computer.
• Run a SCSI cable from the SCSI OUT connector of the MV U320-R to the SCSI IN connector of another unit (such as another MV
U320-R). The other unit must have a terminator inserted in the unused SCSI connector.
Keep in mind that all connected SCSI devices must be rated at, and configured to, run at Ultra320 for maximum data transfer.
Mixing slower devices, such as Ultra2, Ultra Wide, narrow SCSI, etc., could reduce the data transfer rate to the slowest device on
the SCSI channel.
Make sure of the following:
• That the total SCSI cable length is as short as possible (a maximum of two meters).
• To use a terminator at the end device of each SCSI chain.
• That there are no duplicated connections or SCSI ID conflict on any SCSI channel.
Do not exceed a maximum of four devices in a chain, to ensure the reliability of the SCSI data transfer.

Multiple SCSI devices can be connected by a daisy chain, as indicated in the figure below.
Make the following connections:
• Run SCSI cables from the SCSI IN connectors of the MV U320-RX to the SCSI connectors of the host computer.
• Run SCSI cables from the SCSI OUT connectors of the MV U320-RX to the SCSI IN connectors of another unit (such as another
MV U320-RX). The other unit must have a terminator inserted in the unused SCSI connector.
Keep in mind that all connected SCSI devices must be rated at, and configured to run at Ultra320 for maximum data transfer. Mixing
slower devices, such as Ultra2, Ultra Wide, narrow SCSI, etc., could reduce the data transfer rate to the slowest device on the SCSI
channel.
Make sure of the following:
• That the total SCSI cable length is as short as possible (a maximum of 12 meters).
• To use a terminator at the end device of each SCSI chain.
• That there are no duplicated connections or SCSI ID conflict on any SCSI channel. For the MV U320-RX Max, use only Side A.
Do not exceed a maximum of four devices in a chain, to ensure the reliability of the SCSI data transfer.
