SNIA IOPS Test

IOPS performance will typically vary greatly depending on the nature of the IO traffic, including the mixture of Read and Write operations, and the mixture of Block Sizes (the size of the IO operation’s data packet, also referred to as IO Size). This test is designed to benchmark the IOPS performance profile, at a Queue Depth of 32, for random IO operations for 56 different combinations of Read/Write mix % and Block Sizes when in a Steady State, which are of interest to most users.

All of the SNIA’s test specifications define a ‘required’ set of parameters that must be run for the test and then allow the operator to elect to run additional tests with different parameters of their choice. It is the mandatory test with the required parameters that we run. Note that all of the mandatory SNIA tests must be conducted with fully random data

As previously mentioned, a key principle of SNIA testing is to provide a consistent basis for comparing different solutions from different manufacturers.

Here are the results –

Here you can see a visual confirmation that Steady State Convergence was determined at the end of Round 7 (note that steady state convergence is calculated from the 4K line).

 

Here is a 3D and tabular presentation of the results. Users can simply refer to the grid to obtain the R/W mix and Block Size value of interest.  For example, Online Transaction Processing applications typically run at a Block Size of 8K and a Read/Write Mix of 65/35, and users can quickly understand how the device might perform under Steady State for these access characteristics.

You can see that the 4K 100% Writes IOPS result is 154,189 which exceeds Intel’s specification of 139,500. The 4K 100% Read IOPS result is 348,307, which is significantly less than Intel’s specification of 620,000, but remember this is run at a Queue Depth of 32 and a higher result can be expected for higher Queue Depths (please see the Myce/Oakgate Reads and Writes results on page 9, where higher Queue Depths are used).


SNIA IOPS Test – Product Comparison

For interest we present a comparison of the 4K 100% Writes and Reads results with those of the other Enterprise SSDs I have tested –

An excellent result.

An outstanding result!


Now let’s head to the next page, where we look at the results of the SNIA Write Saturation Test…..
