Abstract: An approach for optimizing server-based loads between data centers. The approach receives data from a hardware abstraction layer (HAL) associated with servers in a plurality of data centers. The approach filters the data associated with a portion of the data centers having the highest power usage and thermal state conditions. The approach aggregates the filtered data into performance data groups based on association with a data center. The approach creates two-ratio statistics of the aggregated groups. The approach generates a data center score based on the two-ratio statistics. The approach selects data center sites with the lowest scores. The approach initiates a request to transfer server-based loads from the servers associated with the filtered data to the data center sites with the lowest scores.

Abstract: A computer-implemented method, according to one embodiment, includes: monitoring data requests that are performed on a logical volume in memory at a source location, and tracking changes that are made to data in the logical volume as a result of performing the data requests. A determination is made as to whether a preestablished amount of the data in the logical volume has been changed as a result of performing the data requests since a previous snapshot of the logical volume was captured. Moreover, in response to determining that a preestablished amount of the data in the logical volume has been changed as a result of performing the data requests since a previous snapshot of the logical volume was captured, a new snapshot of the logical volume is captured.
