Yes, microprocessor based mainframes. This is what is all about now. The old CMOS-based technology has been out of production for years, if you don't know. Unisys has been using Intel-based mainframes, or "enterprise servers" for a generation.
Those mainframes, are still alive and kicking, with both Unisys and IBM competing in the market for large processing - and many companies are still running on them.
As an example, Telecom New Zealand's current voice mail platform runs on a resilient, four-mainframe, fully failover capable system from Unisys (I am aware this system is being replaced in 2007 though).
To have an idea of numbers, I've contacted Telecom New Zealand and asked how many voice mail calls are processed by this platform (for other intelligent features run on this installation) and I was told that about 5.5 million calls to Telecom mobiles go through to the voice mail daily. This is for mobile phones only, not counting the fixed line voice mail which is processed in the same platform.
So what a modern mainframe looks like? Just check the picture of this new Unisys Dorado 400 Clearpath series:
Pretty much like any other rack, right? Now compare it with an old Burroughs B5900 about 30 years old), including (from left to right) line printer, tape unit, CPU, consoles, removable disc units:
