go ahead and download InfoScale evaluation binaries, during installation it will ask to provide a key or use 60-days eval key
there are no evaluation product binaries nor eval keys any more (after 5.0 release).
to evauate just use keyless feature (can be set during running installer or by this command vxkeyless.
the keyless mode allows to use for 60 days. (same as evauation keys before) however there is no further 30 days evaluation extension after reached the initial 60-eval period.
