The Memory Factor

Samsung Green Memory Solutions for energy efficient Systems

Ed Hogan

(2)

Special requirements of hosting on Memory

Lowest power consumption during stand-by

Highest affordable density with reasonable

bandwidth

Dedicated Servers Shared Services Storage / Caching

Reliability, fast access, affordability

Challenges: Increasing power consumption …

Limited

Power Budget Higher Carbon footprint =

Higher Cost + Damaged Green image

Increasing cost of energy

Even if you don’t care about energy cost…

Increased number of nodes per rack

Reduce the total number of racks

More room for future expansion

Less Heat & Less Ageing Less replacement service
