An Operation Aware Flash Translation Layer for Enterprise-class Ssds

A novel method to extend flash memory lifetime in flash-based DBMS Abstract: As the capacity increases and the price drops gradually, flash memory is becoming the promising replacement of disk, even in the enterprise applications. However, flash memory suffers from erase-before-write and limited write-erase cycles at the same time, which means the abuse of write,especially small and random writ...

Performance Benchmarking for PCIe* and NVMe* Enterprise SSDs

Query Processing on Smart SSDs

Data storage devices are getting smarter. Smart flash storage devices (a.k.a. Smart SSDs) are on the horizon and package a small programmable computer inside the device. Thus, users can run code closer to the data right inside the SSD, on the “other” side of the I/O bus. The focus of this paper is on exploring the opportunities and challenges associated with exploiting this functionality of Sma...

Data Security Features for SSDs

• Different data storage encryption schemes, such as file/folder encryption and full-drive encryption (FDE). • SEDs as data protection tools, covering methods to manage encryption and SEDs, including management of these security features in concert with software on the host computer. • Industry and government protocols that ensure consistency and conformity of data security systems. These inclu...

Write Amplification Reduction for Flash Memory SSDs

Write ampli€cation is an undesirable phenomenon with ƒash memory based SSDs, which not only reduces endurance of ƒash memory, but also imposes write performance penalty on SSDs. Œis paper discusses how to eliminate or reduce the write ampli€cation of SSD interface presenting ƒash memory as a linear array of updatable sectors so that SSD’s performance and endurance can be both improved greatly. ...
