      Proc: 2x INTEL Xeon E5-2620V3 2.4GHz 15MB 6C/12T

       

      I have a question regarding Intel P3608.

      i don't know if we get all the performance from the NVMe Intel P3608.

      is there any other way to test the performance?

       

      thx

          parsec

          The performance of the P3608 series of SSDs varies with their capacity. You did not specify which size P3608 you have, but looking at your CrystalDiskMark test results, it looks like it is the 1.6TB model.

           

          CrystalDiskMark, and all simple storage drive benchmark programs are not able to test NVMe SSDs appropriately. Like Crystal, they only test with a maximum queue depth of 32, which is the maximum for the SATA/AHCI protocol. The P3608 uses the new NVMe protocol, which is faster and can work with many more outstanding IO requests than a SATA drive can. The testing configuration of Crystal limits the performance results of any NVMe SSD.

           

          If you are comparing the IOPs results of the Crystal test, using a queue depth of 32, to the IOPs specifications of your P3608, which used a queue depth of 256 with a testing program called IOMeter, that is not a valid or accurate comparison.

           

          The IOMeter program is the only free program available that has a chance of testing an NVMe SSD appropriately. Another free program called Anvil Storage Utilities, allows higher queue depth testing, but not to the limits of NVMe.

           

          What makes you question the performance of your P3608? Do you have the Intel NVMe driver installed? There is a new version, just released: https://downloadcenter.intel.com/download/26451/Intel-SSD-Data-Center-Family-for-NVMe-Drivers

              Intel Corporation
              This message was posted on behalf of Intel Corporation

              Hello S.G.

               

              We understand you have some questions in regards to the performance and benchmarking methods suggested for your Intel® SSD DC P3608 Series drive, which is currently being used in a RAID 0 array.

               

              As @parsec correctly stated, the performance specifications for each SSD series do vary depending on drive capacity. Lower capacity equals higher random write IOPS, but lower sequential write speeds, and so forth.

               

              The reason why our latest NVMe* drivers are failing to install is because your SSD is using the Intel® RSTe NVMe* RAID Driver instead. You may only use one or the other. And since your drive is set on a RAID array, the RSTe driver would be the correct one. You're also already using the latest of these.

               

              As far as benchmarking for NVMe* drives, our suggestion is to use IOMeter® for Windows* and FIO® for Linux* OS.

               

              - FIO®: http://freecode.com/projects/fio.
              - IOMeter®: https://sourceforge.net/projects/iometer/.

               

              However, these applications are not the most user friendly, you may refer to the following pages for instructions:

               

              - How to benchmark SSDs with FIO Visualizer.
              - Performance Benchmarking for PCIe* and NVMe* Enterprise Solid-State Drives.

               

              For further IOMeter® instructions, you may also refer to the following document. This user guide was created with the Intel® SSD 750 Series in mind, but it applies equally for all Intel SSD Data Center NVMe* Series.

               

              - Intel® SSD 750 Series Performance Evaluation Guide.

               

              For the best performance, it's important to ensure your Intel® SSD DC P3608 Series is being connected to a PCIe* NVMe* Gen 3.0 x8 connector.

                  @Hello S.G.

                  The way that IOMeter* works, you will need to run two separate tests in order to get both read and write results. As it stands, it does seem like your SSD is under performing, but this could be a test configuration issue.

                  We can recommend running the tests in the following manner:

                  First Test  ̶  Sequential Writes Test:

                  The first workload is the sequential writes test. Instead of using the whole drive, it only uses 1 worker at 32 outstanding I/Os per target over a span of 8GB. This is done by defining the Maximum Disk Size

                  For screenshots, refer the number on the section title to the pictures attached.

                  Setting the target Disk (1.jpg)

                  1. Click on the Disk Target tab.
                  2. Click on Worker 1.
                  3. Click on the target drive
                  4. Set Maximum Disk Size to 16777216 sectors.
                  5. Leave Starting Disk Sector at 0.
                  6. Set # of Outstanding I/Os to 32 per target.

                  Setting Access Specifications (2.jpg

                  1. Go to the Access Specifications Tab
                  2. Under Global Access Specifications, click on New (A new window will open) (3a.jpg)
                  3. Specify a name, ie. 128 KB Secuential Writes
                  4. Set Transfer Request Size to 128 Kilobytes
                  5. Set Percent/Sequential Distribution to 100% Sequential
                  6. Set Percent Read/Write Distribution to 100% Write
                  7. Press OK

                  Setting Up Test Duration (4.jpg)

                  1. Click the Test Setup tab.
                  2. Set for 20 minutes.

                  Running the Test (5.jpg)

                  1. Click the Results Display tab.
                  2. Set Last Update and Update Frequency to 1 second.
                  3. Click the green flag to run the workload.
                  4. Name and save the output file.
                  5. Note the result under Total MBs per Second

                  --------------------------------------------------------------------------------------------

                  Second Test  ̶  Sequential Reads Test:

                  The second workload is the sequential read workload. Just like the sequential writes workload, it only uses 1
                  worker at 32 outstanding I/Os per target, spans over 8GB, and is run for 20 minutes.

                  Setting the target Disk (1.jpg)

                  1. Click on the Disk Target tab.
                  2. Click on Worker 1.
                  3. Click on the target drive
                  4. Set Maximum Disk Size to 16777216 sectors.
                  5. Leave Starting Disk Sector at 0.
                  6. Set # of Outstanding I/Os to 32 per target.

                  Setting Access Specifications (2.jpg)

                  1. Go to the Access Specifications Tab
                  2. Under Global Access Specifications, click on New (A new window will open) (3b.jpg)

                  4. Set Transfer Request Size to 128 Kilobytes
                  5. Set Percent/Sequential Distribution to 100% Sequential
                  6. Set Percent Read/Write Distribution to 100% Read
                  7. Press OK

                  Setting Up Test Duration (4.jpg)

                  1. Click the Test Setup tab.
                  2. Set for 20 minutes.

                  Running the Test (5.jpg)

                  1. Click the Results Display tab.
                  2. Set Last Update and Update Frequency to 1 second.

                      Hello S.G.,

                       

                      I've reviewed the reports you've provided us, and I'm glad to inform you that your SSD is performing very well.

                       

                      SSD performance is advertised based on results from tests ran on new/empty drives, under ideal conditions. Your overall hardware configuration, working temperature, amount of data currently stored on the drive, etc, will have an effect on your performance results. Results close to the 80% mark are considered normal.

                       

                      Here are your results:

                       

                      - Sequential Read: 5126 MB/s (Better than advertised for all capacities: 102% if 1.6TB or 4TB units, 113% if 3.2TB SSD).
                      - Sequential Write: 1952 MB/s (96% if 1.6TB SSD, 75% if 3.2TB unit).

                       

                      As a point of comparison, you may review the following link:

                        I am glad to hear that ...

                        what about random reads and writes.

                        Aren't random reads and writes more important for SQL server

                         

                        What kind of test should i do just to be sure?

                         

                        thanks

                          S.G.,

                           

                          For this, we would need to run the tests again, but modifying only one step:

                           

                          Under the "Setting Access Specifications" portion of the instructions, step 5 tells you to set the "Percent Random/Sequential Distribution". To test your random read/write performance, you'll simply need to make sure this option is set to 100% Random on each of the two tests. All other settings will remain the same.

                           

                          When you get the results, instead of looking under the "Read/Write MBps (Decimal)" columns for Worker 1, you will need to look for the "Read/Write IOps" columns.

                           

                          I've attached an example of what to look for in your results. I added color to some rows in order to make the file easier to read, but that's of course not necessary.

                           

                          If you'd like for us to review and interpret these results for your SSD, feel free to post them on this thread.

                           

                          Best regards,
                          Carlos A.

                              Hello S.G.,

                              Testing for random read/writes is done a bit differently than we would for sequential results. This is due to the difference between random and sequential operations.

                              For random testing, you may follow the steps outlined in the Intel® SSD 750 Series Performance Evaluation Guide. Page 17 for Random Writes, Page 20 for the Random Reads tests.

                              You will need to make sure IOMeter* is configured with a Queue Depth (QD) of 32, Worker =4, and a 100% LBA range.

                              Best regards,

                                  Your random writes look great. In real world conditions, 85% is a great number. However, your random reads are too low, which to be frank, does not make sense considering all your other results have come back normal. Read speeds on solid state drives are expected to be much faster than write operations.

                                  I will consult with our additional resources on possible causes and will let you know what we find.

                                    Maybe i'm doing something wrong regarding tests, but every tests i've done, the IOPS (random r/w) are pretty much the same
