Improved MariaDB performance using Shannon Systems PCIe and atomic writes

Written by Written by Otto Kekäläinen 2 Comments on Improved MariaDB performance using Shannon Systems PCIe and atomic writes

We recently had a chance to test how the Shannon Direct-IO PCIe Flash G3i devices improves the performance of MariaDB. Anybody who cares about I/O performance has noticed that PCIe drives have become readily available in recent years and that they are significantly faster than normal SSD drives connected to the traditional SATA port (not to mention hard disk drives). In addition to being great hardware, the Shannon drives offer an extra boost by having a device driver that supports atomic writes. This means the device guarantees that a write made to it reaches the drive, and thus the MariaDB server does not have to run extra checks like it does on normal hardware.
