Beating the I/O Bottleneck: A Case for Log-Structured Virtual Disks

With the increasing dominance of SSDs for local storage, today's network mounted virtual disks can no longer offer competitive performance. We propose a Log-Structured Virtual Disk (LSVD) that couples log-structured approaches at both the cache and storage ...

Swiss Potential for Hydropower Generation and Storage - Synthesis report

François Avellan, Pedro Filipe De Almeida Manso, Martin Schmid, Paolo Burlando, David Felix

Hydropower (HP) is the backbone of the Swiss electricity system providing around 60 % (36 TWh/a) of the total electricity generated on a yearly average. With the planned phase-out of nuclear power plants, HP and other Renewable Energy Sources (RES) will ne ...

TRIAD: creating synergies between memory, disk and log in log structured key-value stores

Rachid Guerraoui, Willy Zwaenepoel, Diego Didona, Oana Maria Balmau

We present TRIAD, a new persistent key-value (KV) store based on Log-Structured Merge (LSM) trees. TRIAD improves LSM KV throughput by reducing the write amplification arising in the maintenance of the LSM tree structure. Although occurring in the backgrou ...

Control algorithm for a residential photovoltaic system with storage

Christophe Ballif, Nicolas Würsch, Yannick Samuel Riesen

High penetration of photovoltaic (PV) electricity could affect the stability of the low-voltage grid due to over-voltage and transformer overloading at times of peak production. Residential battery storage can smooth out those peaks and hence contribute to ...
