We're connecting up some servers (Mellanox ConnectX-3) and switches (Arista, Ubiquiti) for 10GbE (Proxmox and Ceph HA cluster). So this is all within a single rack - I've read the latency of DAC is slightly better, but probably not noticeable for us.
What are the pros/cons of Twinax DAC SFP+ vs Fiber (single-mode) in terms of durability?
I haven't worked much with fiber before - how delicate is it (in terms of say, snapping inside the sheath).
How tight of a bend-radius can you get for fiber versus DAC cables? For cable management, I'm worried about damaging fiber.
