The automatic elimination of duplicate data in a storage system, commonly known as
deduplication, is increasingly accepted as an effective technique to reduce storage costs …

Data deduplication, an efficient approach to data reduction, has gained increasing attention
and popularity in large-scale storage systems due to the explosive growth of digital data. It …

Flash storage has become the mainstream destination for storage users. However, SSDs do
not always deliver the performance that users expect. The core culprit of flash performance …

This paper considers the problem of how to implement a file system on Storage Class
Memory (SCM), that is directly connected to the memory bus, byte addressable and is also …

Data Deduplication is becoming increasingly popular in storage systems as a space-efficient
approach to data backup and archiving. Most existing state-of-the-art deduplication methods …

Modern solid state drives (SSDs) unnecessarily confine host programs to the conventional
block I/O interface, leading to suboptimal performance and resource under-utilization …

NAND flash-based SSDs suffer from limited lifetime due to the fact that NAND flash can only
be programmed or erased for limited times. Among various approaches to address this …

Flash-based Solid State Drive (SSD) has been productively shipped and deployed in large
scale storage systems. However, a single flash-based SSD cannot satisfy the capacity …

Although flash storage has largely replaced hard disks in consumer class devices,
enterprise workloads pose unique challenges that have slowed adoption of flash …

Multi-stream SSDs can isolate data with different life time to disparate erase blocks, thus
reduce garbage collection overhead and improve overall SSD performance. Applications …
