ZombieSwap: make data centers more energy efficient

Description

DESCRIPTION

  • ZombieSwap lets the cloud virtualization platform exploit available memory in suspended servers as reservoir devices.
  • For a given QoS objective, fewer active servers are needed.
  • ZombieSwap software manages RAM allocation between servers.
  • Requires an adapted server hardware to provide RDMA access to the RAM of suspended servers.
  • Impact on network traffic is limited.
  • Current implementation is a low-level simulator based on real-world data center traces.

COMPETITIVE ADVANTAGES

  • Significant energy saving
  • Exploit suspended servers as reservoir devices
  • Low network impact

APPLICATIONS

  • Data centers
  • HPC
