For a cascading VTrak J5000 DAS connection, use SFF-8644 external SAS cables to perform these tasks:
1. Connect the SFF-8644 SAS HBA card in the host system to
SAS Port 1
on
Controller 1
of the uppermost
Vtrak unit in the rack (
Unit 1
).
2. Connect
SAS Port 3
port on
Controller 1
of VTrak
Unit 1
to
SAS Port 1
on
Controller 1
of VTrak
Unit 2
.
3. Connect the remaining VTrak J5000 enclosures in the same manner.
Note
SFF-8644 ports are full-duplex (
IN
and
OUT
) SAS. So you do not need to
follow this cabling description exactly, it is only used as an example.
