Hello there thinking about a simple 2 computer 10g point to point link. These are both linux machines running modern 5.2+ kernel, ubuntu 19.10. Each computer has one free pci-e 3.0 x4 slot. Which I understand can also take x8 cards if needed (with some slight modification, that I don’t mind).
IDK what I am doing. and only the last choice seem like (to me) something I can reliably count on as working. Currently, my 4 main choices seems to be one of:
1) A pair of these single port cards
2x Mellanox ConnectX-3 MCX341 SFP+10Gigabit Ethernet RMDA/RoCE | eBay
+1 cable Cisco 37-1150-02 SFP-H10GB-ACU10M Direct Attach 10Gb SFP+ 10M Cable | eBay
= £73.60
2x Mellanox ConnectX-3 MCX312 Dual Port 10 Gigabit Ethernet RMDA/RoCE | eBay
+1 cable Cisco 37-1150-02 SFP-H10GB-ACU10M Direct Attach 10Gb SFP+ 10M Cable | eBay
= £99.95
2x Mellanox ConnectX-3 MCX312 Dual Port 10 Gigabit Ethernet RMDA/RoCE | eBay
+2 cables Cisco 37-1150-02 SFP-H10GB-ACU10M Direct Attach 10Gb SFP+ 10M Cable | eBay
= £123.95
2x US $76.95 5% OFF|LR LINK 6880BT PCIe x4 Single Port 10G Gigabit Ethernet RJ45 copper network adapter PC Express Controller lan card server Nic-in Network Cards from Computer & Office on AliExpress
with existing RJ45 cat6 cabling that I already have ( which is 1000mhz, 10gb capable)
= £129.45 total
Another question:
How can I be sure that the SFP+ cable is going to be compatible / work with those cards? It says it’s a used CISCO cable. Therefore should I be buying a MELLANOX branded SFP+ cable instead? Or am I just being paranoid?
Any help appreciated with links to specific product(s). Either on aliexpress or for UK / ebay. Many thanks.
