There are suitably-reliable 20-port Nexus 5010s you can pick-up for
peanuts. I don't believe you can still get support, but maybe you can
get the latest software via PSIRT.

Lots of noise made and power utilised with those, so someone with more
money would obviously punt you towards the [actually white-box] N3k line
for Cisco hardware that does the same thing "in support".

Certainly, that Cat 4500 wasn't made for it with a 48Gbit/sec backplane.
Amazingly, the Cat 4500-X seems to have better density, as well as being
from the same gen of supervisor.

If that's all you need to do this 'VSAN' thing, then why not. See-also:

 Cisco 3650/3850
 Cisco 4500-X
 Extreme X620/X670/X690
 Various Quantas, EdgeCores, Mellanox, ad infinitum.
 Netgear? lol

Have fun!
