Key-value caching is crucial to today's low-latency Internet services. Conventional key-value
cache systems, such as Memcached, heavily rely on expensive DRAM memory. To lower …

We analyze workload traces from production data centers and focus on their VM usage
patterns of CPU, memory, disk, and network bandwidth. Burstiness is a clear characteristic of …

NVMe is designed to unshackle flash from a traditional storage bus by allowing hosts to
employ many threads to achieve higher bandwidth. While NVMe enables users to fully …

As byte-addressable, high-density, and non-volatile memory (NVM) is around the corner to
be equipped alongside the DRAM memory, issues on enabling the important key-value …

The ever-growing capacity and continuously-dropping price have enabled flash-based MLC
SSDs to be widely deployed as large non-volatile cache for storage systems. As MLC SSDs …

Effectively leveraging Flash resources has emerged as a highly important problem in
enterprise storage systems. One of the popular techniques today is to use Flash as a …

Modern data centers are increasingly using shared storage solutions for ease of
management. Data is cached on the client side on inexpensive and high-capacity flash …

The paper presents an adaptive wear-leveling scheme based on several wear-thresholds in
different periods. The basic idea behind this scheme is that blocks can have different wear …

Block traces are widely used for system studies, model verifications, and design analyses in
both industry and academia. While such traces include detailed block access patterns …

Serving as cache disks, flash-based solid-state drives (SSDs) can significantly boost the
performance of read-intensive applications. However, frequent data updating, the necessary …
