Higher density components enable higher density modules, which offer increased performance. This makes it easy to scale up in the future as dependence on server applications increases through expanded virtualization, OLTP, Big Data, in-memory databases, and more - all of which rely on memory density and performance.
Increase energy efficiency and minimize your TCO
Higher-density modules provide more value per gigabit and are also more energy efficient. The increase in density and value contribute to a marked improvement in total cost of ownership.
