Hello everybody,

i'm up to migrate my old standalone NAS into a virtualised environment.

So at the moment im runnung a few tests to verify that everything is working well. First thing i tried is to install ZFSGuru into a virtual Machine which worked like a charme (not like the physical machine http://zfsguru.com/forum/zfsgurusupport/661 ).

After some hassle with the VirtIO drivers ( http://zfsguru.com/forum/zfsgurusupport/658 ) i got it running - with a little help from CiPHER.

;-)

Now - the good news:

broken image

Nice, isn't it?

Best Regards,
minas

Hello again,

it took some time to put all the pieces together and to run the benchmark, but ... it is not really what i have expected:

I'm usure, if the break-in in the sequential read could be caused by a defective harddrive (maybe disk 7)? Or possibly there is not enough memory assigned?

As already mentioned ZFSGuru was put into a VM. Hypervisor is KVM - based on Proxmox VE ( www.proxmox.com ).

The Hardware beneath is an Intel SR1625 Server with 2 x Xeon L5520 and 12GB Ram. HBA is an LSI SAS 9201-16e connected to several Inventec 2U JBOD Appliances. The harddrives are Samsung HD204UI.

The VM got assigned 4 Cores and 8GB Ram. The HBA is given to the VM via PCI passtrough (booting the VM directly from the ZPool is possible).

After all - regarded the fourth and fifth harddrives only, the virtualized system behaves nearly same as my old bare metal setup ( http://zfsguru.com/forum/zfsperformance/169 ).

Sequential write looks good and scales consistently, sequential read breaks in with the seventh disk and is looking terrible chaotic.

Any ideas?

Best regards,
minas
