Air Products SAP ERP configuration

Result of the SRDF/S inflicted scenario:

Observed I/O response times of 50ms or more in T-Log Writes

Could affect checkpoint and lazywriter performance as well

Solution:

Use 3rd party Volume Manager software (e.g. Veritas) to build MetaVolumes with this software. Use 64K as striping size

64K striping size will minimize blocking situation to tolerable size

Success with this measure in a few customers already

EMC is working on a better solution for his case.
