SmartCon

Handling of storage IO in modern operating systems assumes that such devices are slow and CPU cycles are valuable. Consequently, to effectively exploit the underlying hardware resources, for example, CPU cycles, storage bandwidth and the like, whenever an IO request is issued to such device, the requesting thread is switched out in favor of another...

Visualizing Block IO Workloads

Massive block IO systems are the workhorses powering many of today’s largest applications. Databases, health care systems, and virtual machine images are examples for block storage applications. The massive scale of these workloads, and the complexity of the underlying storage systems, makes it difficult to pinpoint problems when they occur.... (more)

Data Sorting in Flash Memory

Because flash memory now provides an economical solution for various portable devices and embedded systems, an NAND flash-based storage system has replaced the hard disk drive in many applications. Recently, the implementation of database systems using an NAND flash-based storage system has become an important research topic. In particular, the... (more)

Design Tradeoffs of SSDs

In this work, we studied the energy consumption characteristics of various SSD design parameters. We developed an accurate energy consumption model for SSDs that computes aggregate, as well as component-specific, energy consumption of SSDs in sub-msec time scale. In our study, we used five different FTLs (page mapping, DFTL, block mapping, and two... (more)

Improving Flash-based Disk Cache with Lazy Adaptive Replacement

For years the increasing popularity of flash memory has been changing storage systems. Flash-based solid state drives(SSD) are widely used as a new cache tier on top of hard disk drives(HDD) to speed up data intensive applications. However, the endurance problem of flash memory remains a concern and is getting worse with the adoption of MLC and TLC flash. In this paper, we propose a novel cache management algorithm for flash-based disk cache, named Lazy Adaptive Replacement Cache(LARC). LARC adopts the idea of selective caching to filter out seldom accessed blocks and prevent them from entering cache. This avoids cache pollution and preserves popular blocks in cache for a longer period of time, leading to higher hit rate. Meanwhile, by avoiding unnecessary cache replacements, LARC reduces the volume of data written to SSD and yields an SSD friendly access pattern. In this way, LARC improves the performance and endurance of SSD at the same time. LARC is self-tuning and low-overhead. It has been extensively evaluated by both trace-driven simulations and synthetic benchmarks on a prototype implementation. Our experiments show that LARC outperforms state-of-art algorithms for different kinds of workloads and extends SSD lifetime by up to 15.7 times.
