DB2 on z/OS and Single Round-Trip J0 With Performance Enhancements in EMC Enginuity 5772+

The SRDFS single round-trip enhancement can reduce latency in an SRDFS Fibre Channel environment based on distance and size of the I/O. This reduction improves response time for I/O. by decreasing disconnect time. The response time decrease for DB2 for z/OS logs may improve customer service levels in existing SRDFS Fibre Channel environments In addition it may be feasible to consider an SRDFS solution for greater distances that were previously prohibitive due to the inherent latency of the distance.
