Which vendors offer benefits for employing certified individuals?

From what I hear, both Cisco and Microsoft give various discounts in the form of hardware , software licenses, and free service calls based on the whether that company has vendor-certified employees.

So, what other vendors do that and what types of benefits do they provide?
Do VMware, EMC, Juniper, Checkpoint, Avaya have these sorts of programs?

Also, do most of these benefits only really apply to re-seller-partners, or could IT departments for large (non-IT)enterprises benefit as well?

I believe Dell and HP have partner programs as well and they do also provide these benefits such as discounts, free calls and certification deals.

I believe any IT staff can benefit from being a partner IMO
