US 2019/0294353 A1 · INCREASING SERIAL READ PERFORMANCE

Abstract

Embodiments of the present invention provides methods, computer program products, and a system for improving serial performance of a computer system storage volume. Embodiments of the present invention can be used to reduce a partition scheme of a storage volume to allow for a computer system to read the storage volume using additional system resources that were previously idle during a serial read operation. Embodiments of the present invention can be used to reserve random-access memory (RAM) to store metadata describing data stored on a storage volume that utilizes a reduced partition scheme. Once the serial read of the storage volume is complete, the embodiments of the present invention can revert the partition scheme back to the original partition scheme for normal, non-serial read operations.

Claims20

Dependent claims

A computer-implemented method comprising:

receiving a serial read request for a first storage volume having data partitioned according to an original partition scheme, wherein the data has corresponding metadata that describes identification information for the data, and wherein the original partition scheme divides the data by a first partition size;
reducing the first partition size of the original partition scheme to a second partition size by an amount less than the first partition size;
splitting the data of the first storage volume into a plurality of partitions, wherein the plurality of partitions each have the second partition size such that, when added together, equals the first partition size of the original partition scheme;
copying the data of the plurality of partitions of the first storage volume to a second storage volume;
and
reverting the data associated with the second partition size to the first partition size.

3 more elements

A computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to receive a serial read request for a first storage volume having data partitioned according to an original partition scheme, wherein the data has corresponding metadata that describes identification information for the data, and wherein the original partition scheme divides the data by a first partition size;
program instructions to reduce the first partition size of the partition scheme to a second partition size by an amount less than the first partition size;
program instructions to split the data of the first storage volume into a plurality of partitions, wherein the plurality of partitions each have the second partition size such that, when added together, equals the first partition size of the original partition scheme;

4 more elements

A computer system comprising:

one or more computer processors;
one or more computer readable storage media;
and
program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
program instructions to receive a serial read request for a first storage volume having data partitioned according to an original partition scheme, wherein the data has corresponding metadata that describes identification information for the data, and wherein the original partition scheme divides the data by a first partition size;
program instructions to reduce the first partition size of the partition scheme to a second partition size by an amount less than the first partition size;
program instructions to split the data of the first storage volume into a plurality of partitions, wherein the plurality of partitions each have the second partition size such that, when added together, equals the first partition size of the original partition scheme;
program instructions to copy the data of the plurality of partitions of the first storage volume to a second storage volume;
and
program instructions to revert the data associated with the second partition size to the first partition size.
