SvSAN provides a 1:1 synchronous mirror for the storage so is especially suited to either: 1. 2-node hyperconverged 2. 2-node hyperconverged with 1 or more compute nodes If adding a third hyperconverged node to the cluster, it depends on how it was originally setup as to how much change is needed. e.g. some configuration changes is necessary, it can all be completed non-disruptively, however during the change disabling the storage replication/HA may be necessary.

It's possible to set network with ring topology for sync storage (not for vm network or management)?let say nic1 node A direct connect to nic0 node B,nic1 node B direct connect to nic0 node C,and nic1 node C direct to nic1 node A?

Hello, I have a question, in my case I have 12 cisco ucs c240 m5 SFF servers, how is the storage distribution done? (always in 1:1 mirror between two servers with RF 2 or another method) and how can i calculate my overall (usable) solution storage ? Thanks a lot ! ^ ^
SvSAN always provides a 1:1 mirror of the data. In your example if there were 12x UCS C240 M5 SFF servers each holding 10TB of RAIDed data, e.g. 120TB of total capacity, all the 12x ESXi hosts would see 6x 10TB mirrored VMFS datastores for a total 60TB of total synchronously mirrored storage capacity.
Hello Mark, What happens when the 3rd node is added to the cluster? does it disturb the existing production environment?
