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 ...

Secure Storage with Replication and Transparent Deduplication

Iraklis Leontiadis

We seek to answer the following question: To what extent can we deduplicate replicated storage ? To answer this question, we design ReDup, a secure storage system that provides users with strong integrity, reliability, and transparency guarantees about dat ...

Storage in IX: a High Performance Storage Layer for a Dataplane Operating System

Lisa Zhou

As storage hardware evolves, the systems and components which interact with them must adapt as well. Outdated assumptions at the operating system level necessitate a dramatic rethinking of the storage path as emerging storage technology offer performance s ...

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, 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 ...
