Hi,
I have a little performance issue with KVM vm's due to the fact that
they do sync write by default (if my memory serves me right). I
currently have servers which are either Cisco C200M2 or SunFire X2270,
so they have 4 x SATA ports and 2 PCIe slots that's it. Right now I
have 4 x 1TB drives in those, I've used raid mirror, not raid-z, but
still I have some little problems, just with the KVM vm's, native
zones are usually fine.
Would anybody here have an idea of either a PCIe card or USB dongle I
could use as a ZIL device? I cannot remove the disks for obvious
reason.
PCIe would be expensive, USB slow.
With only 4 2.5" slots (like the compute node I've just built), using 4
SSDs might be the most cost effective solution.
My last resort idea would be to transition the KVM linux host into
lx-brand, but it's not something I want to explore first.
I would :) All bar one of my Linux KVMs are now LX zones.
