Chaps, I need to draw on your experiences again...

Does the primary IMA Data Store really need to be clustered, or is this more
complication than it is worth. KISS principle, etc.?

I appreciate that high availability is important, but isn't the integrity of
the database even more important.  Without a Data Store, what's the worse that
could happen during the 96 hours, you can't make changes??

If something was seriously wrong the master IMA Data Store cluster node A,
would we want the second cluster to take over?  Is there not a further chance
of corrupting data by having this nice-ity??

If the Data Store becomes unavailable, presumably an app server can still boot
from the contents of the LHC?

thanks, 

Brian

What's keeping you from getting more from your terminal servers? Did you
know, in most cases, CPU Utilization IS NOT the single biggest
constraint to scaling up?! Get this free white paper to understand the
real constraints & how to overcome them. SAVE MONEY by scaling-up rather
than buying more servers.
