  1. Sorry for highjaking but does 6.1 have Active Directory server?
  2. When you use physical RDM mapping, SMART data is beeing passed -through. The virtual scsi controller that is presented to the VM is the problem. DSM doesn't have the right driver for it, hence it cannot read the SMART data. You can try installing vmtools in DSM and see if there is a change. If not, somebody must write a driver for vmware paravirt/ lsi sas/parallel for DSM. You can always passthrough the whole controller to the VM with intel vt-d for DSM direct access to the controller.
  3. Well as i said i gave the whole sata controller to XPEnology VM. You can create a physical RDM following this page https://kb.vmware.com/selfservice/micro ... Id=1017530 The downside of using passthrough is that if you don't have a second sata controller you are stuck on using a USB stick as a datastore for the XPE bootloader and then create a iscsi target in synology and create a datastore in ESXI from it. The 112-115MB transfer rate is stable for the whole transfer (16GB raw image).
  4. I tested with pRDM and passthrough. There is little to no performance penalty between the two. I get constant 112-115 MB transfer rate for large files from Windows 10 PC to XPEnology on the same network. The downside of using pRDM is that is cannot read SMART from the drive (i think it has to do with the virtual scsi controller; tried all option vmwaer paravirt, lsi sas and parrallel; xpe doesn't see the smart and temp of the drive). So i ended up giving the controller to XPEnology and run the bootloader from a USB datastore. Maybe i will buy a cheap pcie sata controller for the datastore. L.E. : i am using VMXNET3 for the network adapter. With Intel e1000 the transfer speeds are ridiculous low.
  5. Hi! One quick question: Is there any performance/stability difference between using the physical raw disk mapping in ESXI vs whole controller passthrouhg in XPEnology? As i understand the difference between the two is that in the pRDM case you have a virtual controller that is beeing passed all the native sata commands from the physical controller. So in theory, XPEnology should get all the commands from the pRDM as it would in case of a controller passthrough. It gets the SMART status but not the temperature of the disk when using pRDM. I don't know how to test the disk spindown to check if it works. As i only have the integrated intel SATA controller i don't want to passthrough because this leaves me with little to none flexibility, and i need to boot the XPEnology VM from a usb stick datastore. And there is no RAM ballooning when passing the whole controller to the VM. Does anybody use pRDM with XPEnology? Thank you!
