VRA-3001T-XX-Y
The VRA-3001T-XX-Y is typically used as an entry level RAID system where a large data
capacity is not required. The RAID controller is separate to the host system and is platform
independent. It is mandatory that a SCSI bus is available at the host side which will connect to
the host interface of the controller. A maximum external cable length between the VRA-
3001T-XX-Y and the host system is two metres in fast/wide single ended mode. Figure 1-1
shows the VRA-3001T-XX-Y configured as a single tower unit connected to a single host
system.
The drives are connected to the RAID controller via two drive interfaces as shown in Figure 1-
2. The top three drives are connected to the first drive channel and the bottom three drives are
connected to the second drive channel.
