You're right -- this is an X-Gene (xgene 1).

The A57 reference came from here:

 https://www.cloudlab.us/hardware.php
 m400 nodes: 45 per chassis, 315 total
 Processor/Chipset: Applied Micro X-Gene system-on-chip
 Eight 64-bit ARMv8 (Atlas/A57) cores at 2.4 GHz
                           ^^^

I'm not familiar with ARMv8's commercial offerings, so I
just quoted the above--which turns out to be wrong,
since A57 is an ARM design and X-Gene is not.

Thanks,
