Storage subsystem is considered as the performance bottleneck of computer systems in
data-intensive applications. Solid-State Drives (SSDs) are emerging storage devices which …

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 …

Since solid-state drives (SSD) have high read speed, they are integrated into a traditional
hard disk drive (HDD)-based storage systems for improving the overall performance. The …

As data volumes of high-performance computing applications continuously increase, low I/O
performance becomes a fatal bottleneck of these data-intensive applications. Data …

We present H2DP, a holistic heterogeneity-aware data placement scheme for hybrid parallel
I/O systems, which consist of HDD servers and SSD servers. Most of the existing approaches …

Multi-tiered Parallel I/O systems that combine traditional HDDs with emerging SSDs mitigate
the cost burden of SSDs while benefiting from their superior I/O performance. While a multi …

Hybrid object storage systems provide opportunities to achieve high performance and
energy efficiency with low cost for enterprise data centers. Existing object storage systems …

As the performance gap between processors and storage devices keeps increasing, I/O
performance becomes a critical bottleneck of modern high-performance computing systems …

In this paper, we consider to improve scientific workflows in cloud environments where data
transfers between tasks are performed via provisioned in-memory caching as a service …

3-D flash memory faces a number of challenges, including thermal issues and process
variation. The high temperature will cause charge loss and lead to the fluctuation of …
