Failover Cluster not using all allocated RAM

We are running on SQL 2000 on Windows 2003. We have active-passive
clustering set up. We have 16 GB of RAM on each box. This past
weekend, we failed over. I noticed that the Total Server Memory went
from about 15.5 GB to 8 GB. I have been trying to figure out why this
has occurred. Any help would be greatly appreciated.

One cannot accuse me for knowing too much about Windows clustering,
but surely in a cluster, each node has its own memory, hasn't it? That
would mean that a failover is the same as running DBCC DROPCLEANBUFFERS,
that is the entire cache is flushed. Of course, as SQL Server continues
working, the cache will grow again. But if it only has grown to 8 GB
this far, this indicates that so far that you have only touched 8 GB
of data - actually even less, as this also includes the plan cache.
