The authors propose RoLo (Rotated Logging), a new logging architecture for RAID10 systems for enhanced energy efficiency, performance and reliability. By spreading destaging I/O activities among short idle time slots and proactively reclaiming the stale logging space, RoLo rotates loggers among a logical logging space pool formed collectively from the free storage space available among mirrored disks. Therefore, without the extra dedicated log disks and the corresponding centralized logging, RoLo eliminates the additional hardware and energy costs, potential single point of failure and performance bottleneck.
