Use cluster or ceph

Both are free, hardware agnostic and the future of software defined storage. And Red Hat can provide enterprise support if you need.

LinOTP + soft tokens

On: Ask Slashdot: Open Hardware/Software-Based Security Token?

Check out LinOTP which works with just about any soft tokens like Google Authenticator and the Red Hat FreeOTP token app. Also works with the awesome Yubikey. I like how the tokens are user managed which drastically eases support.
