Using transparent compression to improve SSD-based I/O caches
Flash-based solid state drives (SSDs) offer superior performance over hard disks for many workloads. A prominent use of SSDs in modern storage systems is to use these devices as a cache in the I/OExpand

Azor: Using Two-Level Block Selection to Improve SSD-Based I/O Caches
Flash-based solid state drives (SSDs) exhibit potential for solving I/O bottlenecks by offering superior performance over hard disks for several workloads. In this work we design Azor, an SSD-basedExpand

Transparent Online Storage Compression at the Block-Level
In this work, we examine how transparent block-level compression in the I/O path can improve both the space efficiency and performance of online storage. We present ZBD, a block-layer driver thatExpand

ZBD: Using Transparent Compression at the Block Level to Increase Storage Space Efficiency
In this work we examine how transparent compression in the I/O path can improve space efficiency for online storage. We extend the block layer with the ability to compress and decompress data as theyExpand
