Re: Sounds like yet another
The FAS, FlashRay and Altavault platforms all use the same basic 6RU chassis, with at least one X86 processor motherboard in it. The 8040, 8060 boards use Sandybridge procs, and the 8080 board uses IvyBridge. Not sure about the Altavault and FlashRay, but they're one of the two.
The second slot can contain another controller or an IOXM, which is a PCIe bridge and a bunch of extra slots. It also takes a front plane Infiniband connection and shoves it out the back in two QSFP connections to accomplish HA.
So basically what the 6RU AFF8080 is, is just two AFF8080 controller modules in one chassis instead of two. No magic re-engineering, just putting existing parts together.
