Tegile looking at some really flashy fabric

Tegile, which has just launched a 2-tier IntelliFlash HD all-flash array, has plans to ramp up its capabilities dramatically. The system provides 512TB of flash in a 3U enclosure. Tegile chief marketing officer Narayan Venkat said that the system will be at the 1PB level in a year's time, meaning a rack could hold 20PB in …

Infiniband

If they're already using Infiniband, and it offers loads of bandwidth with very small latency, it seems mad to adopt a new fabric.

The problem with IB, is very few, (outside of HPC), use it.

What interconnect does Cray use? Again, in HPC?

One can't be reminded about what they say about farmers here in Good Old Germany:

"Was der Bauer nicht kennt frisst er nicht"

The problem with IB

IB HCAs - (DDR, QDR, FDR) what type of interface slot do these connect into ?

PCIe (X4, X8, X16). Still requires a driver to load, work with kernel calls etc.

NVMe provides common set of "tools" over PCIe. Violin was one of the first to provide direct-attached storage via PCIe. It is a core component to their arrays today. What DSSD is already providing is very promising. The others, they are still evaluating how to bring the tech to market. .
