Hi batiati, Please try with fixed .vhdx. Please also make sure that you are using SCSI controller for .vhdx connection. Did you try proposed tweaks? Yes, the vhdx is fixed size, the VM is Gen2 using SCSI controller. I followed all best-practices on StarWind's KB (the iSCSI disks works great on the ...

Hi, So, almost solved this issue I don't know why, but all VMs cloned from that specific .vhdx showed the same performance issue. I created a new .vhdx file and installed a fresh Windows on it, and now it's much better: ------------------------------------------------------------ | 100% Writes | 100...

Hi Oleg, Could you please clarify what network cards are you using, what vendor? It's a QLogic (or Broadcom) 10Gb SFP+ for iSCSI and SYNC on separated NICs. But it doesn't seem like a problem, I have tested with iperf and diskspd.exe between the Hyper-V host and StarWind node, both with great perfor...

Folks, I need help with a problem not directly related to StarWind VSAN. I have a fresh install of a converged Hyper-V environment where I can access the iSCSI volumes from the host with a good performance, higher than 160k / 90k IOPS (measurement by diskspd.exe, read and write with 4k sequential bl...

I note in Windows Server 2016 (fresh install, updated and VMtools installed) I am capped at approx 6GB however the same test in Linux sees results of almost 10Gb Try to increase the number of threads on iperf using the -P parameter, you should achieve a better result on windows. .\iperf3.exe -c 10....

Right, it was already asked before: there is not way do add a sync partner from powershell cmdlet. https://forums.starwindsoftware.com/viewtopic.php?f=5&t=5282&p=29544&hilit=hapartner#p29544 So, I was trying to simulate a full node recovery (supposing that I've lost even the config files...

Hi
I found the RemoveHAPartner.ps1 on StarwindX folder and it worked just fine.
But now I removed the old partner and I want to add a new one. I can't figure out how to use the Add-HAPartner cmdlet to do it.

Could someone provide an example for Add-HAPartner cmdlet?

Hi all, Let me share my experience dealing with outdated hardware in my first StarWind deployment. I have two refurbished Dell PowerEdge R610 dual Xeon X5630 16GB RAM acting as storage (converged scenario) with StarWind vSAN Free Edition. Each node has 6 x 1 TB SSD (RAID5) and 2 x Broadcom NetExtrem...

Hi Oleg, Thank you for replying, I use StarWind Free on my prodution environment and I really enjoy it. It is a great product. Just for the sake of knowledge, and preventing anyone from inadvertently choosing ReFS for their CSVs thinking they are making the best choice based on this benchmark. Am I ...

Hi folks, I've just read the PERFORMANCE HIGH SCORE news you guys released, it's amazing, congratulations! I don't know if here on StarWind's forum is the best place to ask it, but there is a point on this benchmark that has raised a doubt: Is it mentioned that ReFS for the CSV has achieved a better...

Thank you for replying Unfortunately, I cannot confirm I have seen 10Gbps Broadcom based NICs that would hit at least 6Gbps. You can try the following command and see whether that changes anything: .\iperf3.exe -c 10.10.1.1 -P 4 -w 16M Hope that helps. Nope, nothing changes with -w 16M . If I put -P...

Hi, folks I'm benchmarking my environment, but I'm a bit confused about the propper whay to use the iPerf3 tool on a 10Gbps connection: When I run iPerf like ".\iperf3.exe -c 10.10.1.1", my results are about 4Gbps. So, I had to specify ".\iperf3.exe -c 10.10.1.1 -P 4 " for four p...

Hi @Sekkmer, You have done a great job on StarWindXExtLib, thank you for sharing it. I'm currently working on a very simple GUI in order pro provide basic functions to my level 1 staff: create/extend a volume, put/remove on maintenance mode, etc. Using StarWindXExtLib has been pretty handy for me, s...
