Hi,

So I configured a Nextenta vm on my ESXi 5.1, it runs on a local SSD of the ESXi.
Added 3 of 4 ssd's in Sharkoon via raw mapping to the vm (4th is not seen, probably esata cable loosened, have to check that).

Created a NFS zraid with these 3 SSD's and put 1 vm on it.
nextenta
Not what I expected, honestly. Ok, it's a vm (Nextenta) but still disks are mapped directly, memory is not used heavily .... Performance of 1 SSD is faster then this ZFS ZRAID.

Shouldn't I use ISCSI or caching, or logs ...?

Am I missing something?

Please advise.
J.

You mentioned some tools to do this (portable ones I think), could you mention them again? I'll then run these and paste the results here.

Btw, does it (ZFS Nextenta) get faster when you use it longer, even without cache configured? Seems to be so ....

Loading nextenta volume with vm's now.
Note: could configuring ISCSI bring improvement versus NFS?

Napp-it contains Bonnie and DD benchmark tests, which will perform the tests actually on the NAS.

Others include I/O Meter, CrystaldiskMark, HD Tach

iSCSI could be faster than NFS, again benchmark and test, check with Jumbo Frames enabled and disabled.

I cannot use jumbo frames since not all my devices support it. Afain, I just needed a blackbox fast nas, nothing more, nothing less.
I ll follow the config you made and tested. Don t need or want to spend to much time anymore testing/configuring.
My lsi should arrive soon, I ll order 3 2tb disks and will install solaris with nappit on bare metal then. Can you share your config/help me further configuring then? When finished I hope not to need to touch anymore and focus again on vms/windows no storage anymore.

Yes, as I've maintained ZFS in Oracle Solaris has always been the best for performance.
