Description
Cloud data centers operate at low utilization rates resulting in significant energy waste. VM consolidation allows to put some servers in sleep mode (low energy), but in practical it is quickly limited by the available memory of active servers.
• 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
