I am seeing huge memory price increases as you scale up in amount (4gb dell dimms are about $42/gb whereas 8gb dell dimms are $120/gb). So I am just currious how much memory you use in your virtual hosts and how many hosts you have? Right now we have 2 with 32gb each, at the rate of the price slope, I could almost add a whole new node to the cluster w/32gb for around 8K (or 2 nodes w/32gb for 16K) rather than upgrading both existing nodes to 64gb for 14K.
