56 IBM TotalStorage DS6000 Series: Performance Monitoring and Tuning
Volumes for an isolated workload should be created as evenly as possible across all Ranks
allocated to the isolated workload and similarly, volumes for a resource-sharing workload
should be created as evenly as possible across all Ranks allocated to the resource-sharing
workloads. Host-level striping (open systems Logical Volume Manager striping or z/OS
Storage Groups) should then be used across all the volumes belonging to the workload.
One exception to the recommendation of spreading volumes is the case of files or datasets
which will never be accessed simultaneously, such as multiple log files for the same
application, where only one log file will be in use at a time.
