The last Vax was decomm'd 11/8/1994 (I beleive the last vaxen were
pulled form the clusters in the summer of 1993.
The last dec was officially de-supported 7/21/1998 and powered off
sometime around November of 1999. I think these were pulled from the
clusters in the summer of 1996. That said, we didn't put suns in the
athena.dialup pool until July of 1997, a full year after the last DECs
left the clusters and way overdue based on the load/performance of the
DEC dialups. We were clearly behind schedule with this upgrade all
the way around.
However, as Mark noted, we'll evaluate the actual usage after spring
term. I'm hoping everyone with quietly move over to the linux boxes
and no one will care, but I'm sure that's not actually realistic.
