V890 PCI SCSI card maximum data rates

I've just spent a couple of hours searching through Sun web pages for an
answer to the following...

We are attempting to evaluate a V890 as a backup server and need to estimate
the maximum data throughput rates on the PCI slots. From a block diagram of
the V890 we can see that four of the 33MHz PCI slots share the same bus.
What does this imply about the data rates we could see from SCSI cards on
that bus? Could we drive each of the cards to the limit of it's ability or
would each card run at a reduced rate because the bus is shared?

Ideally I need a reference to a Sun document, but any opinion would be
useful.

Thanks,
