So the main difference between a FileIO and DiscIO is the speed. Thanks

Secure your unRAID SSH Access and Tunnel using PuTTY

This was easier than I thought Been wanting to setup ssh keys for my server for a while now, thanks! -
with multiply cache pools coming up, is it possible to set an pool as an iSCSI LUN? I guess that is no problem with an fileIO at least. Is there any benefits with DiscIO over FileIO or the other way around?
-
No, no upgrade or anything like that. So the drive should be formatted in Unraid before setting it up for iSCSI, because that is the only way to set the pass-through flag. I tried that and it showed up in Windows10 as formatted and ready to use, so seems to work as intended
-
Yup, it was gone from the Unraid GUI at least, I did not check the drive if the files was there. Now Im testing out BlockIO as I have a spare 1TB I can test with, it also works right out of the box as long as the drive was not formatted in Unraid it worked as I expected it. But the unassigned dives plugin can still format the drive, so I guess its best to be careful and remember what drive you use for what until this is a part of Unraid officially. Oh, and yes, I get the expected write speed to the BlockIO LUN It is not a problem connecting different LUNs to the same

Ok, I see what you mean about the reboot thing, I had to shut down the server to add some discs and when I rebooted the entire iSCSI plugin was gone XD I added the fileIO as new, just used the same name in the GUI and the data was there

WriteBack was default false so that is off, can I enable that without recreating the LUN? CPU i7-4790, cache is an old WD green 2TB, parity is an WD red 10TB and the array is a mix where the newest ones are WD Red 10TB Edit: Tried with an new LUN with writeback enabled, now it goes over 100MB/Sec for some time, then drops to 3-4MB/sec, then back to over 100MB and so on. Looks to me a cache is filling up, then waiting for the drive, then filling the cache and so on. This was tested on a FileIO on the cache drive. Same happens with the LUN on the array. Going to try o

So Im testing around both fileIO on array and on the cache but both gives me the same speed, around 5MB/sec I cant seem to figure out why it is so slow. Connected on a 2.5Gbit link directly to server Unraid 6.9 Beta 35

Are they bundled together? Because I installed only the "iSCSI Target" plugin and got the gui under "settings"

Good to know For now I don't use it with any important data.

Hello I`m testing the iSCSI beta plugin and got it to work, but I have a question: On the 3--LUN page, when I choose the IQN + Volume and click "Create FileIO LUN" nothing shows on the page, is it suppose to show something here at all? Its clearly the button works as I got the iSCSI volume up and running on my W10 PC. Also both buttons says "Create FileIO LUN", I guess the bottom one should say "Create Block LUN" Keep up the good work Looking forward to see how this evolves!

I have done it, and did it just like ChatNoir describes. As far as I know, Unraid uses the serials on the drives to identify them so what port they are connected to does not matter.

How much pci-e bandwidth is really needed for gpu trans-coding? Is it enough to put an gpu in a 1x slot?
-
So I take it once the nvidia drivers are part of core unraid, this version will be no more?

Thanks Now I finally got me ordered one too
