Is the Two-Node setup for Starwind an Active/Active setup or active/passive?

StarWind's two-node setup is an active-active scenario.

With this setup is there any risk of a split brain scenario occurring? If so what protections are built in to ensure that the system normalizes it's self?

Instead of forcing people to use a 3rd host as withness we use a hearbeat channel (preferably set up on a separate physical NIC to avoid a SPOF) that constantly has the nodes pinging each other. This way if the synchronization channel fails the HA device that is second by priority will be disabled to avoid split-brain.

What if it fails due to the primary hosts failure? Sudden power outage etc. In a two node setup would both nodes then go down?

Both hosts are constantly in sync,and each VM has access to it's virtual disk on both hosts. If one of the node fails, then the cluster just continues working if it's VMware FT or the VMs failover and everything continues working in case of Hyper-V or VMware HA.

How would we configure the iSCSI connection in Hyper-V for this? Using MPIO?

Exactly. We actually have a lot of guidance to configuring MPIO properly on our webiste. Here is a Knowledge Base article with details: https://knowledgebase.starwindsoftware.com/guidance/how-to-configure-mpio-with-starwind-correctly/

Apparently I'm going to be starting with the unusual questions. In your V2V Converter, you have the option to convert to Microsoft VHD, why the Microsoft VHD and not just VHD?

Thaks for great question. It should actually work with XEN as well.

Looks like we'll have to double check this and then make some changes to the V2V to reflect it supports both.

@StarWind_Software I've seen that recently you've released a process for Linux (presumably the KVM hypervisor).

When will there be some updated instructions for XenServer?

Can't share exact release dates just yet, but this is high on our priority list. Both KVM and Xen integration are currently in the works and will be available with details guides, once we are sure that they are up to scratch. Also, feature requests are welcome on this thread.

Hello guys! We are looking forward to all your questions and me, @LaMerk and @ABykovskyi will do our best to fill you in on where we stand currently, what we are looking at doing in the future and respond to any other questions you have.

Hello everyone, I'm Andrew Tuzov from StarWind. I am a Special Projects Manager (not as sinister as it sounds).
Also, don't forget to join our AMA tomorrow!
