July 7, 20179 yr I'm closing in on my final components for my unRAID build and I need to select my 10GbE networking. My server will be in a separate room from my main desktop (45ft away), so I need distance to be supported. I'm really new to 10GbE, but I've been doing lots of reading. As I understand it, SFP+ is limited to 10m cabling with standard DAC, but with transceivers connected to fiber, it can go much farther. Is this correct? 10BASE-T ($400-450): Dell W605R or Intel X540-T1 ASUS XG-U2008 There is also this 2 port card (not sure what advantage this gives me): AOC-STG-I2T SFP+ ($475ish): Mellanox Connectx-2 Cisco SFP-10G-SR Transceivers OM3 Fiber Cabling TRENDnet TEG-30284 Is there an advantage to one or the other? I definitely like the switch I have selected for the SFP+ setup over the RJ45 setup. 2 extra 10GbE ports for future expandability. That said, I do already have several rooms with CAT6 runs, so that makes 10BASE-T attractive too. Has anyone found one to be faster/better than the other with unRAID? To save money, I might just do two cards and a direct connect at first, then add in the switch later down the road. Love any feedback and personal experience with setups similar to this. Hoping to run a Raid 10 cache with at least 4 SSDs, so I would like to maximize over network data rates. Thanks!

July 10, 20178 yr SFP+ DAC cables are limited but with the right SFP+ module and fibre they can go up to 80km. I would also guess SFP+ switches are easier to get hold of and cheaper new. I've only ever run 10GBASE-T over Cat6a cabling, not sure how reliable it would be over Cat6.
