In-Memory computing - part 2

Hardware for Data in RAM solution cost

A typical Dell/HP/IBM/Cisco blade with 256GB of DRAM will cost below $20K if you just buy on the list prices That brings the total cost of 2TB cluster well below $200K (with all network and power equipment included and 100s TBs of disk storage).

According to Wikibon article - "Data in DRAM" - we can see that Data in RAM solution can be very expensive because of max 96GB per ndoe RAM limiation.
So in general having 2 - 1TB Blades defenetly redices the cost.
