It is also not a problem, that you cannot do vmotion with your SAN-VM (How would you vmotion your physical disks??) But you must provide: - real hardware access to controller and disks (needs pass-through/vt-d) for your SAN VM OmniOS - assign enough RAM for caching (Arc-cache), the more the faster - be not CPU limited If you need a ZIL or better disable sync write depends on use case. If you build an All-In-One (ESXi with virtualized SAN), all your guests go down together with your SAN, so mostly a ZIL costs money and performance but cannot improve security. You should also trythe ESXI highspeed VMXnet3 network drivers (unless you find problems with them like some others) If you intend to use compression, use LZ4 (with newest OmnoOS stable with bugfixes for LZ4) Have you read my manuals (hope they are helpful)? <a class="moz-txt-link-freetext" href="http://www.napp-it.org/doc/downloads/all-in-one.pdf">http://www.napp-it.org/doc/downloads/all-in-one.pdf</a> and <a class="moz-txt-link-freetext" href="http://napp-it.org/doc/ESXi-OmniOS_Installation_HOWTO_en.pdf">http://napp-it.org/doc/ESXi-OmniOS_Installation_HOWTO_en.pdf</a> Gea On 13.05.2013 20:55, C.

We can not use bare metal server, and I know that is a problem. We are thinking in disable zil. Is it recommended when omnios is installed as a vm?? And we can not use pci passthrough esxi feature due to vmotion and HA features enabled in these esxi servers. Any recommendations about how to configure this vm? At first stage we can allocate 8 gb of ram and 4 vcpus. And wr need to manage 5 tb of data with snapshots and maybr compression in certain zfs volumes.
