摘要:	Growing demand for key-value store applications is building a strong momentum for the commercialization of key-value hard disk drives. To achieve better performance, flash-based solid state drive is the next ideal candidate for commercialization in the foreseeable future. However, the existing fixed-sized management strategies of flash-based devices would potentially result in low storage space utilization when managing variable-sized key-value data. In addition, the low storage space utilization would further lead to the degradation of device performance, due to low invalid data space reclamation efficiency. The space utilization issue motivates this paper to propose a key-value flash translation layer design to improve storage space utilization as well as the performance of the key-value solid state drives. A series of experiments was conducted to evaluate the proposed design, and the experiment results of space utilization and device performance are very encouraging.
