Abstract
A computer-implemented method and apparatus for detecting misalignment in a data storage stack by opening a first storage layer in the data storage stack, performing a plurality of accesses of the first storage layer, each of the plurality of accesses starting at a different offset, and determining an optimal offset based on a performance benchmark of each of the plurality of accesses.
Claims20
A computer-implemented method comprising:
- opening a first stack layer in a data storage stack;
- performing a plurality of accesses to the first stack layer, each of the plurality of accesses starting at a different offset;
- and
- determining an optimal offset by a processing device based on a performance benchmark of each of the plurality of accesses.
1 more element
A system comprising:
- a processing device;
- and
- an I/O subsystem coupled to the processing device, the I/O subsystem including a storage device;
- and
- an alignment utility implemented by the processing device to determine an optimal offset for the storage device.

A computer readable storage medium having a set of instructions stored therein which when executed cause a computer to perform a set of operations comprising:
- opening a first stack layer in a data storage stack;
- performing a plurality of accesses of the first stack layer, each of the plurality of accesses starting at a different offset;
- and
- determining an optimal offset based on a performance benchmark of each of the plurality of accesses.
