Data locality restoration

If the blocks of the file are not located as what you want, restore or change the locality of the file.

The IBM Storage Scale FPO provides interface for you to control all first replica of the blocks, all second replicas of the blocks, and all third replicas of the blocks in specific nodes. For example, you can have the first replica of all blocks located in a specific node so that the applications running over the node can read all data from local disks.

Note: The IBM Storage Scale FPO does not support the control of the location of only one or part of blocks. For example, you cannot control the location of block 1 or block 2 without changing the location of block 3.
