Executing CBPTest Tool - Disk Performance Testing Tool results in a log file Results.txt. To interpret these results:
NOTE: There has been an update to the script used and the way the results are displayed. Per the comment from Matt Larsen at the bottom of the page:
There is a change in the output. In order to increase accuracy, multiple test files are used. So you will see individual results per file, and a total. The INDIVIDUAL results should be nearly identical, and that is the value we use - not the total.
- Open Results.txt a text editor such as Notepad
- Scroll to the first set of throughput results and look for the total MB/s number under "Write IO" on line 92. This is the Sequential Writes result.
- Scroll to the second set of throughput results and look for the total MB/s number under "Read IO" on line 197. This is the Random Reads result.
- Scroll to the third set of throughput results and look for the total MB/s number under "Write IO" on line 316. This is the Random Writes result.
- Compare the results to the requirements listed on Page 15 of Bit9 Security Platform v7.2.3 - SQL Server Configuration for Bit9SqlIo. Note that CBPTest is a newer test that has replaced Bit9SqlIo, but the required performance metrics are identical. Screenshot:
In the example shown above, the storage is capable of supporting a Cb Protection instance with up to 500 endpoints, with "Random Writes" being the limiting factor.
