LSFS Slow NTFS Format Via iSCSI

[xpystchrisx]

I have the following setup in a test environment.
Dell R510 running Server 2016 with StarWind V8 Trial
2x Xeon X5660
32GB RAM
Perc H700 with 12x 4TB SAS in RAID10
1x Sun F40 PCIE Flash Card (Nytro Drive)
1x Samsung 512GB SSD
2x 1GbE ports for iSCSI Targets

My client machines are Dell R610's with two 1GbE ports for iSCSI running Server 2016 in a FCI running Hyper-V.

When I provision a thick volume the client systems can format the disk in seconds and things are ready to go. If I provision an LSFS volume the system takes approximately 4 hours to format. LSFS is configured as a 4TB device with 10GB of L1 and 200GB of L2 from the F40 card or the Samsung 512GB SSD. I know that this is not optimal but the environment is for testing only. I have tried giving the LSFS volume 2GB of L1 and 20GB of L1, with the same results.

I'm trying to figure out what I'm doing wrong. Any pointers would be great as once the format is complete the performance of StarWind is incredible.

I'm seeing the same performance, is this normal or has there been a solution found?

Sorry about the delay, I have since nuked the server that I was using and am testing out VSAN Free with it and another that is the same config. I will run the LSFS config and see how this goes with the VSAN Free software.

Fine, keep us updated.
