摘要

现有的存储机制很少考虑数据的保存特性。这些可以在数据集之间产生不同大小的片段。在某些情况下,这些碎片可能会严重影响系统性能。在本文中,我们设法修改当前的存储机制。我们在经典的数据管理架构中引入了一个称为数据桶的额外存储单元。接下来,我们修改数据管理机制来改进我们的设计。通过按访问信息保存数据,大大减少了分片的数量和分片的大小。考虑到不同的数据特性和存储设备条件,我们还通过将数据保存在不同的空间来提高固态硬盘(SSD)的使用寿命。实验表明,我们的设计对SSD的存储密度和实际使用时间有积极的影响。

Data Bucket-Based Fragment Management for Solid State Drive Storage System
The current storage mechanism considered little in data’s keeping characteristics. These can produce fragments of various sizes among data sets. In some cases, these fragments may be serious and harm system performance. In this paper, we manage to modify the current storage mechanism. We introduce an extra storage unit called data bucket into the classical data manage architecture. Next, we modify the data manage mechanism to improve our designs. By keeping data according to their visited information, both the number of fragments and the fragment size are greatly reduced. Considering different data features and storage device conditions, we also improve the solid state drive (SSD) lifetime by keeping data into different spaces. Experiments show that our designs have a positive influence on the SSD storage density and actual service time.
