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!
George

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-based
virtualisation 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
