Four-Channel Profile/Multiple RAIDs
This configuration, see the following illustration, has a four-channel Profile (one
MDR and one SDR) and two symmetrical RAID Storage chassis chains (the RAID
chain attached to the MDR matches, in number of disk modules, the chain attached
to the SDR).
1. Connect a SCSI-2 cable from the Profile MDR rear panel connector to the first
RAID chassis SCSI A IN connector in the MDR chain.
2. Connect a SCSI-2 cable from the first RAID chassis SCSI A OUT connector to the
next RAID chassis SCSI A IN connector in the MDR chain.
3. Connect a SCSI-2 cable from the second RAID chassis SCSI A OUT connector to
the next RAID chassis SCSI IN connector in the MDR chain.
4. Repeat Steps 2 and 3 for the remaining RAIDs in the MDR chain. See page 2-13
to determine the maximum number of RAIDs that can be connected to your Profile.
5. Connect a SCSI-2 cable from the Profile SDR rear panel connector to the first
RAID chassis SCSI A IN connector in the SDR chain.
6. Connect a SCSI-2 cable from the first RAID chassis SCSI A OUT connector to the
second RAID chassis SCSIA IN connector in the SDR chain.
7. Connect a SCSI-2 cable from the second RAID chassis SCSI A OUT connector to
the next RAID chassis SCSI IN connector in the SDR chain.
8. Repeat Steps 6 and 7 for the remaining RAIDs in the SDR chain. Remember to not
exceed the maximum number of RAIDs that can be attached to your Profile.
9. Connect a SCSI terminator plug to the SCSI A OUT connector of the last RAID
chassis in each chain.
