VSAN & iSCSI Accelerator

Hello,
Are there any known issues if we'd like to use iSCSI Accelerator for connection with iSCSI JBOD on the same server with installed VSAN Free for HyperConverged scenario (with 2-way sync repl - 3 servers in total) ?
Thanks,
Tomasz

Glad to see you at StarWind Forum again. Please make sure to reconnect the iSCSI sessions to let iSCSI Accelerator do its job.

Could you please verify steps required for this scenario?
0. Setup LUN(s) on iSCSI JBOD
1. Install iSCSI accelerator
2. Connect iSCSI JBODs via accel
3. Install VSAN Free
4. Carve-out required CSVs for HV
5. Expose CSVs to HV...
-> Is it still worth doing CSVs on iSCSI loopback or it might be easier to go SOFS and expose that to HV locally or other solution?
Please note, I'm talking about hyper-converged scenario where HV and VSAN live on the same physical machines (3-node cluster).
Is there any way that iSCSI accel may interfere with VSAN iSCSI target server?

That's correct.
127.0.0.1 is needed.
Pass HA devices to the cluster as CSVs.
You may also want to set a delayed start for StarWind VSAN as underlying storage will be connected over iSCSI. What you can do is set the manual start for StarWindService, and create the task that starts StarWindService via PowerShell in 2 mins after OS start.
