We used HammerDB 3.3 to run the OLTP test cases. These test cases show that SRDF/Metro reduces the Recovery Time Objective (RTO) for the SQL Server failover cluster drastically as the devices are highly available on both sides of SRDF/Metro cluster. The Windows failover cluster can bring up disk resources after failover very quickly. Once the disk resources are up, the SQL Server cluster role restarts very quickly as well, resulting in very brief application downtime in the case of failures.
