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
