We investigate the problem of creating an energy proportional storage system through
power-aware dynamic storage consolidation. Our proposal, Sample-Replicate-Consolidate …

Flash memory-based non-volatile cache (NVC) is emerging as an effective solution for
enhancing both the performances and the energy consumptions of storage systems. In order …

This paper presents the design, implementation, and evaluation of BORG, a self-optimizing
storage system that performs automatic block reorganization based on the observed I/O …

Persistence of in-memory data is necessary for many classes of application and systems
software. We propose Software Persistent Memory (SoftPM), a new memory abstraction …

We use a novel virtualization-based approach for computer architecture performance
analysis. We present a case study analyzing a hypothetical hybrid main memory, which …

This paper considers the problem of efficiently managing storage space in a hybrid storage
system employing flash and disk drives. The flash and disk drives exhibit different …

Data migration schemes are critical to balance the load in storage clusters for performance
improvement. However, as NAND flash based SSDs are widely deployed in storage …

Uncertainty and conflicting stakeholders' objectives make many requirements and
architecture decisions particularly hard. Quantitative probabilistic models allow software …

While hard drives hold on to the capacity advantage, flash-based solid-state drives (SSD)
with high bandwidth and low latency have become good alternatives for I/O-intensive …

Disks use a considerable portion of the total energy consumed by a video server. Solid-state
disks (SSDs) can be used as a cache to reduce disk speeds, thereby decreasing the power …
