Virtualization provides significant cost savings by allowing otherwise underutilized resources to be time-shared between multiple virtual machines. While efficient techniques for optimizing CPU and I/O device utilization are widely implemented, time-sharing of physical memory is much more difficult. As a result, physical memory is increasingly becoming a bottleneck in virtualized systems, limiting the efficient consolidation of virtual machines onto physical machines.

Transcendent Memory (tmem for short) provides a new approach for improving the utilization of physical memory in a virtualized environment by claiming underutilized memory in a system and making it available where it is most needed.

If this sounds interesting, you are in the right place. You will hear directly from the developer, Dan Magenheimer, Sr. Kernel Engineer for Oracle, about the details of this technology and how it can help you utilize memory more efficiently.
