Hi,
As far as I know the way to do HA on SmartOS is to have the app itself
be HA, not the zone or kvm.
I could be wrong. SDC is a pretty awesome interface as mentioned, if you
want something more lightweight there is also Project FIFO.

Hi George,
I am interested in the free, do-it-yourself environment and have
already taken a glance of SDC's online documentation, but it's kind of
huge and the part I found regarding high availability was in their FAQ
- so it wasn't very explanatory.
Nonetheless, if you have a link on how it can be established, then
please share it and I'll see if it fits our needs.
Thanks for your quick answer!

Greetings George,
Are you interested in a paid solution or a do-it-yourself environment?
If your answer is do it yourself, then you should have a look at the
open sourced smart data center code and documentation in github.

Hi everybody,
We are looking for a virtualisation solution and during my search I
came across SmartOS. Our project will not be large, it will be
initially comprised of 4-5 48core machines and we will need to be able
to add physical machines no more than once or twice a year. We need to
be able to have network separation among some of our VMs (so we need
virtual network support, 802.1q vlan support, etc), we want to have a
(web) interface to manage VMs and we wish our solution of choice to
allow for high availability, in the sense that a VM will need to be
able to maintain its state if one or more of the underlying physical
devices have crashed, depending on our configuration.
I've read that SmartOS supports live migration and high availability
through Quemu using SmartDataCenter, and I also read that FiFo
accomplishes something similar using LeoFS. As far as LeoFS is
concerned, its documentation mentions that the consistency level is
responsible of the redundancy that is established, but this
configuration is performed only once, during the design phase. This, to
my understanding, is a somewhat limiting factor, since even in our
setup, which will not change more than twice a year (by adding new
physical nodes), we cannot be certain from day one how much our
infrastructure will grow in order to plan ahead. And even if we did, I
don't know how much the additional write replicas that will have to be
assigned during the design phase -for example- will affect the overall
performance. On the other hand, I am not sure how SDC's high
availability solution works, and hence I decided to ask this list how
high availability can be achieved in a SmartOS-ba
sed!
virtualis
ation environment.
Some more requirements I was given by my team involve configurable VM
boot order and docker, but I explained them that the latter is not
mandatory.
Thank you for your time in advance,
George Mamalakis
