Abstract
Embodiments described herein are directed to volume creation such that the volume is created in the storage system that is closest to the group of servers that the container is likely to be launched. Through such embodiments, the volume can be created or migrated in anticipation to a launch or a relaunch of a container.
Claims18
A method for storage management in conjunction with computing unit management in a system comprising a plurality of servers and a plurality of storage systems, the method comprising:
- for a request of creating a new volume or attaching an existing volume for a computing unit to be launched:
- determining, from configuration information, one or more servers from the plurality of servers to which the computing unit is to be launched;
- estimating performance for each storage system among at least a subset of the plurality of storage systems connected to the determined one or more servers;
- selecting a storage system from the at least the subset of the plurality of storage systems connected to the determined one or more servers based on the estimated performance;
- and
- creating a new volume or migrating an existing volume to the selected storage system.
A non-transitory computer readable medium, storing instructions for storage management in conjunction with computing unit management in a system comprising a plurality of servers and a plurality of storage systems, the instructions comprising:
- for a request of creating a new volume or attaching an existing volume for a computing unit to be launched:
- determining, from configuration information, one or more servers from the plurality of servers to which the computing unit is to be launched;
- estimating performance for each storage system among at least a subset of the plurality of storage systems connected to the determined one or more servers;
- selecting a storage system from the at least the subset of the plurality of storage systems connected to the determined one or more servers based on the estimated performance;
- and
- creating a new volume or migrating an existing volume to the selected storage system.
