    HPE R1N26A Composable Fabric FM 3180 25GbE Switch

    Anyone have experience with these? I'm eyeing a new in box one, but not sure if I need a subscription, licenses, or anything else to use it. I'm hoping to plug it in and it work out of the box. Any insight would be greatly appreciated, thanks!

    SFP 1Gb 1000Base-T modules known to work in Mikrotik

    Hello, folks. I have a Mikrotik CRS317 with 16 SFP+ cages. I have stuff for the 10G connection I need to make, but there are several 1G ethernet devices I need to hook to it as well. I've tried a couple of SFP modules, but while there is information in Webfig that the module is present, it will...

    Help me understand LC module compatibility

    Hello STH. I'm just getting started with a home server and hit a stumbling block that I could do some help with. I bought some mismatched 10G nics for peer to peer over DAC between my r720 server and clients. Works fine. Now I need more distance so want to try fibre so bought another chelsio...

    Connecting Quanta LB8 (48x10G SPF+) to 1G Network (or simple sfp+ to sfp?)

    Hi everyone, i just got a Quanta LB8 Switch with 48 SFP+ Ports. The Problem is that my whole network is currently 1G copper (but i have 4 SFP uplinks on my switch). I need a simple way to integrate my "new" 10G Switch into my network. I thought SFP modules would work in a SFP+ port but i seems...

    Mellanox SFP 10G nics

    Hello all, After a bit of a fight with one of my PC's which utterly refused to detect the Mellanox at all ( turned out to be a BIOS issue with Agesa ) I now have them up and running. I'm getting about 380Mb per second transfer under Windows 10 Pro from an 8 Drive Raid 6 array on a 9361 to a PCIe...

    DAC compatible with Cisco P81E VIC and Ubiquiti US-16-XG

    I ordered some SFP-H10GB-CU3M compatible (supposedly) DACs from fs.com, and although they're nice and thin, and work with my Mellanox Connectx-3 cards in my NAS', they are not compatible with my P81E 10GbE cards in my UCS servers. Can anyone recommend a good DAC in 3-5m distances to connect my...

    Hi, I need to build a server with a port to connect a 1Gbps single mode fiber. There seems to be little PCI-e cards available that offer 2 ports (i'm looking for either 2 or 4 ports for expansion) SFP cages where I can use any optics. Question is, will a 10GbE nic work with SFP optics (instead...

    SFP28 optical module and SFP/SFP+

    Is there difference in physical form between SFP28 optical and SFP/SFP+ ? Should SFP28 optical module (like the one in the following link) fit into SFP/SFP+ cage ? https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/ethernet-sfp28-optics-product-brief.pdf Kevin
