Creating ASP2 on an 820

Hello,

we have an 820 with the 6718 disk units (17GB) all mirrored. 20 drives so we
get 170GB net space.

We'd like to create an ASP2 with 2 drives for journalling (also mirrored). A
short talk with our CE told us to:

               - remove 2 units from ASP1 (mirrored pair)
               - create ASP2
               - add unconfigured units to ASP2

Makes sense to me - do you know any gotcha's ? We are currently at 52%
capacity.

My main concern is performance... Is one mirrored pair enough for
journalling - how do I calculate performance?

We have a second business unit on a remote site also with an 820. I'm
thinking about switching to remote journalling 
in the long run. What are the points here - is a 2Mbit leased line enough?

Thanks for your comments,

Oliver
