Abstract
The described technology is generally directed towards maintaining a consistent logical data size with variable protection stripe size in an array of independent disks system. According to an embodiment, a system can comprise a processor that can execute computer executable components stored in a memory, and storage devices. The components can receive a configuration from another node of the redundant array of independent disks system based on a selected number of logical data blocks to configure disks, and configure, based on the selected number, the storage devices to store data in a number of stripes, with the logical data blocks mapping to the storage devices. The data can be stored in the storage devices, wherein parity information for a stripe of the number of stripes is stored for the stored data, and wherein a logical data block of the number of logical data blocks corresponds to the stored data.
