The last and most stable Isis2 release was V2.2.2020, so Vsync is starting with that version number. This code is identical to Isis2 V2.2.2020 except for a global replace of Isis by Vsync.
I've collected all the files associated with the out-of-band code for Infiniband RDMA platforms into ib.zip. This dll is only needed if you use the "out of band" operations within Vsync, and will only work if your system either has an Infiniband network or an RDMA Ethernet ("ROCE network interface card"). When properly installed and configured, you gain extremely fast data transfers under control of Vsync, but outside the core Vsync multicast data movement layer. We are planning on replacing this in the future with a new way of doing RDMA internal to Vsync.
Vsync can be used with IronRuby, F#, and there is a stand-alone daemon server that can be used to do command-line actions with the system. However, all the associated materials need to be ported from Isis2.codeplex.com, so for the time being, we do not have downloads in shape for you on those here. If you do the ports (which are totally trivial), let us know and we'll add them to the download list!
