Hello erhansahin,
The performance of the drive will depend on the type of data and workload, or the test configuration. Please review the Intel® SSD DC P3700 Product Specification, pages 10-11, for the advertised performance. The performance tests were measured using IOMeter* on Windows* Server 2012 R2 driver with Queue Depth 32 and 4 workers and other settings mentioned in the specifications.
The fact that the drive performs well in other Operating Systems suggests a limiting condition in the virtualized environment. Please review the following items, as they are directly involved in the performance and functionality of the drive:
1. Use the most recent driver for your Intel® SSD and VMware*. Current file: VMW-ESX-5.5.0-intel-nvme-1.0e.1.1-2791094.zip
2. Check with the Motherboard or Computer Manufacturer to make sure that your SSD is connected to a PCIe Gen3 x4 slot or connector, otherwise, it may show degraded performance.
3. Make sure your SSD is using the most recent firmware, currently 8DV10151, with bootloader revision 8B1B012F. This can be updated using Intel® Data Center Tool:
In an virtual environment there are other factors involved, like number of Virtual Machines, concurrent access and Hypervisor or VM configurations. These would be outside of the SSD support scope, however, you can review the following document for more information about this:
