Peps Posted May 31, 2016 Share Posted May 31, 2016 G1610T (will be replaced soon with i3-3240 or i3-3250 or i5-3470T) 16 GB RAM Bay 1-3: 3x3TB WD RED Bay 4: 1x 2TB ODD Port: 256GB SSD I want to install ESXi on a SD card and use the SSD as datastore for the vms. (3-5 VMs: webserver, omv, small windows-testlab) On one VM, I want to install omv and attach bay 1-3 with rdm to the vm, to do a sw raid 5. The 2TB hdd should be datastore used by the other vms. Is this configuration possible?I think i have to put the B120i to AHCI mode, right?I read, that with a configuration like this one, there will be no trim for the ssd. Any recommendations how to do it better or completely different? I don't want to buy another raid controller. Link to comment Share on other sites More sharing options...
yodafett Posted June 2, 2016 Share Posted June 2, 2016 I do not think you can pass just the drives through by themselves it would have to be the whole controller. what you could do though is make a vm with openfile/freenas/etc have 3 drives pointed to it then have that vm make the software raid then present that as another vmfs as a iscsi target since it is internal it runs at bus speed and not just 1gb that said I would suggest booting off the on board usb port with a sandisk fit drive as there have been read issues on the sd card Link to comment Share on other sites More sharing options...
einsteinagogo Posted June 2, 2016 Share Posted June 2, 2016 you can use unsupported RDM mode, with the controller in AHCI mode. checkout my Experts Exchange article here on how to do it... https://rdsrc.us/8z0Cyo it's a bit of a fudge, hack, unsupported etc your mileage may vary etc Link to comment Share on other sites More sharing options...
Tuurbo Posted June 3, 2016 Share Posted June 3, 2016 Unfortunately ESXi has extreme performance problems with de Gen8 in AHCI mode, what results in a non-working setup.

See more info here: http://homeservershow.com/forums/index.php?/topic/11143-howto-esxi-with-jbod/ Your setup is interesting. So RDM is not necessary? Do you geht SMART and spindown working?

Tuurbo Posted June 3, 2016 Share Posted June 3, 2016 I'm not sure if I understand your question. I still use RDM, but it's no longer necessary to configure/create a RAID(0) for every disk. I'm still working on how to get SMART and/or spindown of the harddisks working. Link to comment Share on other sites More sharing options...
Peps Posted June 8, 2016 Author Share Posted June 8, 2016 Im now using ESXi with AHCI. No problems with port resets. RDM works fine. Also OMV can read SMART data. Great. But: When I copy large files, the write speed slows ddown after a few seconds from 100mb/sek to 30mb/sek. Read data works with 100mb/sek. Anybody an idea?
