Performance (AES encryption) of 80219 processor

hi there..
Intel sells a product "Entry Storage System SS4000-E"
(http://www.intel.com/design/servers/...00-E/index.htm)
containing a 80219 processor. The system runs linux and sources are
available so it is possible to change the os to write all data aes
encrypted to the disks.
But unfortunately I have no idea what throughput can be achieved.
Hope somone knows something about this processor or product. Some
benchmarks would be great. I could not found any information about
this.

thanks a lot!
