Title
Evaluating Host Aware SMR Drives.
Abstract
Shingled Magnetic Recording (SMR) technology increases the areal density of hard disk drives. Among the three types of SMR drives on the market today, Host Aware SMR (HA-SMR) drives look the most promising. In this paper, we carry out evaluation to understand the performance of HA-SMR drives with the objective of building large-scale storage systems using this type of drive. We focus on evaluating the special features of HA-SMR drives, such as the open zone issue and media cache cleaning efficiency. Based on our observations we propose a novel host-controlled indirection buffer to enhance the drive's I/O performance. Finally, we present a case study of the open zone issue to show the potential of this host-controlled indirection buffer for HA-SMR drives.
