P6000 SLI Bridge

Looking for recommendation for SLI Bridge to couple two P6000 in HP840Z chassis running CentOS/Scientific Linux/Red Hat.

Is it even possible to do with Linux?

Any certain vendor better than others?


Are there other vendors for a Quadro P6000 besides PNY anyway?
Regarding SLI on Linux, it’s supported but support is…not good. So depending on use case, YMMV.
