Any hypothetical OpenVMS port would need to deal with arcane details 
such as inetd, the startup via SYSMAN or SYSTARTUP_VMS.COM and either 
via DCL or GNV bash, system parameters and/or process quotas, the Java 
versions of those C pesky run-time configuration logical names, 
probably getting Java running in a detached process, and some other 
dreck.

Now if you want to find reasons not to do something, that's entirely 
your call.   If you want to try Cassandra, then load one of the 
provided installers or load a VM guest and go try it.

Whether some site has a list of prerequisites or the rest?  That's 
interesting and useful information and it'd be nice to have.  Here, I'd 
expect to need Java and some startup hackery for odd-ball boxes.  But 
FWIW, these same (lack of) platform support details can also be a basis 
for inferring whether the platforms you're interested in and are using 
are current and maintained and ubiquitous and have an active community 
of open-source users and maintainers.  Or whether you're using what are 
exotic platforms.

As for the answers to your Microsoft Windows questions, I do not know.
