CIOs and IT managers agree that memory is emerging as a critical resource
constraint in the data center for both economic and operational reasons.
Regardless of density, memory is not a shareable resource across the data
center. In fact, new servers are often purchased to increase memory capacity,
rather than to add compute power. While storage capacity and CPU performance
have advanced geometrically over time, memory density and storage performance
have not kept pace. Data center architects refresh servers every few years,
over-provision memory and storage, and are forced to bear the costs of the
associated space, power and management overhead. The result of this
inefficiency has been high data center costs with marginal performance
improvement.
