RE: adding disks

["Dave Snyder" <Dsnyder@xxxxxxxxxx>]

The increase in activity is a good thought I had not considered. The
main reason we are adding these is to accommodate test and research data
that needs to be retained and accessible on the system. What about
assigning these new disks to a new ASP that will only be used for this
type of data, thus not impacting production data performance?

Any problems with putting some of these new disks in the system unit and
others in the expansion units?
