andyps Posted July 7, 2017 Share Posted July 7, 2017 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! Quote Link to comment
Perforator Posted July 7, 2017 Share Posted July 7, 2017 You can find Intel X540 knockoffs on ebay for ~90 dollars. Quote Link to comment

Chris Pollard Posted July 10, 2017 Share Posted July 10, 2017 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. Quote Link to comment
