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.
