The most recent opportunity came one week ago. In the ensuing couple of hours we discovered two interesting things. First, the bad news. Our most recently introduced service is a network name service that, among other things, provides automatic lookup to determine which of 33 independent network file servers is holding your files. Although it was intended to eventually run this network name service on a set of small machines dedicated to just that purpose, we initially deployed the name service as an extra process on three of our big file servers, choosing three that were known to be lightly loaded because they also provide file backup copying service.
