Test results summary
11 Dell EMC PowerVault ME4024 8,000 Mailbox Exchange 2016 Resiliency Storage Solution using 10K drives | 3917-ESRP
6 Test results summary
This section provides a high-level summary of the data from ESRP testing. The detailed HTML reports
generated by the ESRP testing framework are shown in the appendices of this document.
6.1 Reliability
Several reliability tests were run for 24 hours to verify the storage can handle a high I/O load for a long period
of time. Both log and database files were analyzed for integrity after the stress test to ensure no database or
log corruption.
The following list provides an overview of the test results:
• No errors were reported in either the application or system log.
• No errors were reported during the database and log checksum process.
• No errors were reported during the backup or restore processes.
6.1 Storage performance results
The primary storage performance testing is designed to exercise the storage with the maximum sustainable
Exchange type of I/O for two hours. The test shows how long it takes for the storage to respond to an I/O
under load. The following data is the sum of all logical disk I/Os and average of all the logical disk I/O latency
in the two-hour test duration. The test results for each server are listed in appendix A.

6.2 Database backup and recovery performance
There are two test reports in this section. The first one measures the sequential read rate of the database
files, and the second one measures the recovery/snapshot performance (playing transaction logs in to the
database).
