Abstract
A method for pre-staging data includes obtaining a DST configuration of a virtual volume at a first point in time. The method also includes creating a Point-in-Time copy (PiT) in a destination storage pool when the virtual volume includes at least one PiT, or reconfiguring at least one virtual volume segment to contain a hot-spot. The virtual volume may or may not have PiTs. The method further includes recording the DST configuration, specifying the DST configuration be applied to the storage array at a second point in time, and applying the DST configuration to the storage array at the second point in time.
Claims20
A method, comprising:
- obtaining a DST configuration of a virtual volume at a first point in time, the virtual volume being provisioned from at least one storage pool of a storage array;
- creating a Point-in-Time copy (PiT) in a destination storage pool when the virtual volume includes at least one PiT;
- or
- reconfiguring at least one virtual volume segment to contain a hot-spot, the at least one virtual volume segment configured to be moved to at least one corresponding storage pool;
- recording the DST configuration;
- specifying the DST configuration be applied to the storage array at a second point in time;
- and
- applying the DST configuration to the storage array at the second point in time.
A method, comprising:
- provisioning a virtual volume from at least one storage pool of a storage array;
- designating at least one virtual volume segment of the virtual volume for mapping a virtual volume range to a virtual drive range;
- identifying at least one hot-spot in the virtual volume;
- recording at least one Dynamic Storage Tiering (DST) configuration;
- applying the at least one DST configuration to the storage array;
- verifying the validity of the at least one DST configuration;
- and
- pre-staging data according to the at least one DST configuration prior to at least one of a peak production period or an off-peak production period.
A computer-readable medium having computer-executable instructions for performing a method for pre-staging data, said method comprising:
- provisioning a virtual volume from at least one storage pool of a storage array;
- designating at least one virtual volume segment of the virtual volume for mapping a virtual volume range to a virtual drive range;
- identifying at least one hot-spot in the virtual volume;
- reconfiguring the at least one virtual volume segment to contain the hot-spot;
- recording at least one Dynamic Storage Tiering (DST) configuration;
- applying the at least one DST configuration to the storage array;
- verifying the validity of the at least one DST configuration;
- and
- pre-staging data according to the at least one DST configuration prior to at least one of a peak production period or an off-peak production period.
