Compatible SAS or eSATA controllers for ESXi 7.X Passthrough


Recommended Posts

I was able to deploy DSM 7.1 with Redpill on ESxi 7.X. However when passing though my ASM1602 adapter only 1 Drive is recognized in the 8Port eSATA enclosure. I was able to do this after changing the SataPortMap to 088. Before this I could only see the Virtual HDD.


The drives are properly recognized in the Bare metal BIOS and also on a Virtual TrueNAS with passthrough (Same ESXi) but somehow the ESXi and Redpill can only see one drive.


On the SATA map config of the RedPill installer I can see 32 channels of the VMware Virtual adapter and 2 port channels from the ASM1602


The adapter is visible on the DSM Linux OS when executing the lspci command. So the question is why only one Drive is recognized.


Are there any eSATA or SAS Adapters that are compatible with DSM?


From what I have read online over the past few days it seems that the issue could be due the fact that the eSATA is using a port multiplier( being able to pass 4 SATA drive signals over a single eSATA port)


I want to be able pass through the actual drives to the host VM and not Virtual drives.


Is there any configuration required for the DiskIdxMap or  InternalPortCfg?


Any thoughts?
