Twin Datacenter Interconnection Topology
IEEE Micro, 2014The authors propose an interconnection topology suited to server-centric networks based on Twin graphs. The topology exploits graph theory to cost-effectively improve network scalability and resilience. The authors discuss datacenter network topology by comparing Twin interconnection topologies to different datacenter topologies (that is, Fat Tree ...

Soft Failures in Large Datacenters
IEEE Computer Architecture Letters, 2014A major problem in managing large-scale datacenters is diagnosing and fixing machine failures. Most large datacenter deployments have a management infrastructure that can help diagnose failure causes, and manage assets that were fixed as part of the repair process.

Ensemble routing for datacenter networks
Proceedings of the 6th ACM/IEEE Symposium on Architectures for Networking and Communications Systems, 2010This paper describes Hash-Based Routing (HBR), an architecture that enhances Ethernet to support dynamic management for multipath networks in scalable datacenters. This work enhances HBR to support flow ensemble management for large-scale networks of arbitrary topology.

Embedded Systems as Datacenters
2010Designing embedded systems the way we did 20 years ago is still alive and well. As expected, with declining costs, embedded systems are appearing in more and more applications. Advances to the state of the art in creating such systems, where memory and processor are precious resources, have continued, and this work is to be applauded.

Advance Reservation System for Datacenters
2016 IEEE 30th International Conference on Advanced Information Networking and Applications (AINA), 2016Reservation mechanisms have been used to guarantee users' access to cluster resources at the desired time instead of adopting a batch mode processing, where jobs are processed at the nearest time in the future, risking to wait an uncertain amount of time before being run.

A Case for Heterogeneous Flash in the Datacenter
2013 IEEE 33rd International Conference on Distributed Computing Systems Workshops, 2013We explore the idea of heterogeneous NAND flash which possesses pages and blocks of multiple sizes. This heterogeneity can then be exploited to accommodate the diversity in data access patterns found in most datacenter storage workloads. We identify various tradeoffs offered by such pages and blocks.

Killer Fabrics for Scalable Datacenters
2010 IEEE International Conference on Communications, 2010Most datacenter networks are based on specialized edge-core topologies, which are costly to build, difficult to maintain and consume too much power. We propose enhancements to layer-two (L2) Ethernet switches to enable multipath L2 routing in scalable datacenters. This replaces an expensive router with commodity switches.

Proceedings of the 5th European conference on Computer systems, 2010
Contemporary datacenters comprise hundreds or thousands of machines running applications requiring high availability and responsiveness. Although a performance crisis is easily detected by monitoring key end-to-end performance indicators (KPIs) such as response latency or request throughput, the variety of conditions that can lead to KPI degradation ...
