Hi Jennifer,

We have been using HP DL360 G2 dual 1.4Ghz CPU with 2Gb of RAM and 36Gb
drives. Our directory has 10 times less entries than you. We have about
100 search queries/sec. and less than 30 modifications/hour. We did some
stress tests before the servers go into production: we could reach about
1,000 search queries/sec for a single server. 

Hope this helps.
