Questions:

We are looking at installing a DLT library into our 
cluster. Currently we have 2 7640's and 1 6630 in the
cluster. I know there is no SCSI adapter for the VAX 
based processors so we are considering the installation
of an Alpha 4000 with 4 PCI to SCSI FWD adapters
(one adpater per tape drive) and 2 PCI to CI adapters
(we have 2 CI's in our cluster). The DLT drives would be
the DLT7000 or TZ89. My questions is, would a Alpha 4000
2 CPU (5/400) with 1 GB of main memory be able to keep
all four of the DLT7000 drives at their rated speed
(5MB/sec)? Also were can I get a performance and
benchmarks figures for such a configuration?

Many Thanks
