Hello All !
Setup:
Intel(R) Xeon(R) CPU E5-1620 0 @ 3.60GHz
SUPERMICRO X9SRL-F
2x3tb HDD + 1x512GB HDD + 1x120GB SSD
32GB Mem
I've tried to pass-through both 6-port and 4-port onboard SATA controllers to guest OS (Nexenta) one by one. The controllers passed-through (and assigned to Nexenta) w/o any problems, but the HDDs weren't visible to the guest OS. I've tried different combinations of controller/HDD, but no luck.
Maybe somebody was in the same situation, how can I fix it ?
I'm gonna to try RDM next weekend, but I've read it's not very good solution...
Thanks.
RDM is good solution for you. For using Pass-Through, you need to reserve all virtual machine's memory.
But you can use RDM without that.
Also you can direct your SATA HDD to your VM easily.

Thanks for reply. I'll try it as soon as have some free time...
Hello again !
Thanks for tip, I've tried it and it works ok. I've started up Nexenta, created NFS share, connected it to ESXi as a datastore. Migrating 50GB VM from dedicated HDD to NFS was ok, speed ~150MBs.
But when I've tried to start migrated VM there was no luck (VM status is Powered On, but actually there no any reaction from VM).
I started to dig deeper.
I've tried to migrate that VM back to dedicated HDD. Read speed from Nexenta's NFS became incredibly slow (KBs) and the connection is dropping permanently. 1% of copying took several hours. As I understand, ESXi starting to copy from one DS to another, loses connection, trying to restore it, starting to copy again, etc...
There's nothing bad in logs in both ESXi and Nexenta.
I have no more idea where to dig to. Maybe someone got ideas ?
Thanks.
