Hoping one of the gurus can help me out here with this mod.
I have a FreeNAS Box up and going that I plan on using for some virtual machines.
I am going to do a peer to peer (20Gb) between my Hosts and My FreeNAS Box.
Here is the equipment that I purchased.
For FreeNAS Box: (Cards - T520-CR Chelsio T520-CR PCIe3.0x8) Optics: (Chelsio SM10G-SR 260-0012-00 FTLX8571D3BCL-CL)
For VMHosts: (Cards - Intel 82599ES 10Gbps Dual Port PCI-E X520-DA2 E10G42BTDA) Optics: : (Intel E10GSFPSR FTLX8571D3BCV-IT E65689-001 SFP+)

What cable should I be using between these optics?

Thanks

The FTLX8571D3B* are standard multimode optics, in your case vendor-locked (-CL Chelsio, -IT Intel) and all you need to do is run a fiber patch.

We have a big thread on 10G: https://forums.freenas.org/index.php?threads/10-gig-networking-primer.25749/

The ideal cables are OM3 50/125 multimode cables, but you can use OM2 50/125 or even OM1 62.5/125 especially if the distance is short. OM3 will get you up to 300 meters. If you're only going a few feet and you already have OM1 cables, try them and I'd bet a buck they work fine and you'd never notice the difference.

You want "LC" connectors and a duplex cable (two fibers). Basically something like https://www.fs.com/products/41729.html
