 DSO — DASD Space Optimizer
DSO maximizes DASD through fully automated functionality
DSO maximizes DASD through fully automated functionality, executing defrag functions automatically, quickly, permanently, securely and nearly unnoticed. The fragmentation index is kept on a consistent optimized level, the utilization of the volumes increases considerably, production is safer and additional costs will be saved!
DSO maintains the fragmentation-index permanently at an optimized level and keeps defrags transparent to the production environment. The storage administrator defines the volumes that are to be optimized using selection criteria that eliminates maintenance. The highest fragmentation is usually evident where many activities (like create, extend and delete of datasets) take place. Typically the work, test and batch production volumes are hit the most. DSO allows different thresholds to be set for different groups of volumes.
DSO runs as a started task which constantly observes the fragmention of the user defined volumes. According to the user given time interval, DSO selects the volumes that are the ‘best candidates’ (where the defined thresholds have been reached) for the defragmentation. DSO keeps the fragmentation rate low. Users defined the amount of track relocation for each volume process.
