Poor P3700 performance within Hyper-V

I'm scratching my head over this one. Any suggestions are welcome.

I have a single Windows Server 2012 R2 VM using SCSI and a fixed disk within a Hyper-V host. The VHDX is the only VM on the P3700 storage. Performance benchmarks using Atto are very low compared to the advertised specifications for this drive.

Am I missing something? Does the P3700 need to be formatted using a non-standard block size? Thanks for looking!

Hello thubbard55,

Please understand that the performance values vary by capacity and form factor for the Intel® SSD DC P3700 Series and performance specifications also apply to both compressible and incompressible data. Please try IOMETER for benchmarking for even more accurate results. You can download it from the link below.

Thanks for that Aleki.

This is the 800gb model. The read / write speed at the 4k size test is 15mb per second. Compare this to the 590mb read / 144 write that this benchmark produced:

Thanks, I'm working on this now.

 

Can you clarify if I need to reformat the drive using the 8k block size since this is a Windows Server operating system? That is what the screenshot seems to indicate. Or is it that I just need to run the test at 8k sector size even though NTFS is formatted at 4k?

Hello thubbard55,

In this case it does not really make much difference and you can use either one.
