Failure Diagnosis for Datacenter Applications
… failure diagnosis remains a major challenge for datacenter operators. Current datacenter applications are increasingly architected around loosely-coupled modular components: each component can scale and evolve independently. However, when application failures occur, they become much harder to …

Centralized performance control for datacenter networks
An ideal datacenter network should allow operators to specify policy for resource allocation between users or applications, while providing several properties, including low median and tail latency, high utilization (throughput), and congestion (loss) avoidance. Current datacenter networks inherit …

Segment backup: datacenter-disaster tolerance for stream processing systems
We design a datacenter-disaster tolerance solution called segment backup for stream processing systems. During regular running, segment backup inserts barriers into the normal tuple stream to indicate the backup versions and ensure node-level synchronization of multiple input streams. Additionally, …

Techno-economical evaluation of intra-datacenter optical transceiver designs
The evolution of data center network interconnects is based: at the component level, on cost, power, and bandwidth density; and at the system level, on cost, unit count, footprint, and implementation time. The decision for iterative vs. transformational design depends critically on the product …

Reduction of Power and Virtual Machine Migration Inside a Cloud Datacenter
Today’s datacenter consumes high amount of electrical energy for its operation. It increases day by day, thus increasing the operation cost and carbon dioxide emission. To reduce the power consumption at a datacenter, a model with an adaptive threshold virtual machine (VM) consolidation method that …

Cutting the datacenter tax in heterogeneous systems: a coherence-spectrum approach
Modern datacenters pay two persistent overheads: a memory tax from memory management and optimization features such as memory deduplication and compressed swapping, and a network tax from end-host processing that surrounds the NIC rather than the packet transmission itself. This thesis reduces …
