Abstract
Efficient handling of disk input/output (I/O) operations is disclosed for a storage system supporting a doubly mapped redundant array of independent nodes. Delegating I/O operation management to a mapping layer component can support adapting I/O operation performance based on a topology of a real cluster supporting doubly mapped clusters. In traditional techniques, some corresponding real node topologies can result in inefficiently moving data from a first real node to a second real node and then promptly moving it back from the second real node to the first real node. These, and other, inefficient disk I/O conditions can be mitigated or avoided based on the presently disclosed techniques that can support more direct access to mapping information. Moreover, the disclosed techniques can support proportionately adapting an order of performing I/O operations due to the inherent isolation of real nodes and real clusters in accord with the disclosed subject matter.
