fiber

I have a 30m run between my two main network switches at home that snakes around the walls and through a couple of door frames, like this (doors do not fit snugly so they can still be closed without squeezing the cable as is) Cable is flat Cat6 and runs at 2.5Gbps without issue. I want to...

Hello. New here and been searching for days for help and cannot figure this out. Any help or recommendations are appreciated. I'm a small business owner (and home labber) and have FTTP. It comes in as simplex, single mode OS2 with an SC APC connector. I have a full TP-Link Omada setup with...

Hi, my house is going to receive a fiber connection in a few weeks/months and i obviously want to use it. But there is a problem. I cant run a cable inside my house, because the room where they are going to install it in has only one door and that is a fire protection door, which has to be...

Preface I've been planning on running copper and fiber in my home for a while. I really need a decent network closet for the hot/loud switches to live. I recently made a major score while dumpster diving which included all the Cat6a I will need. I also found a bunch of jank fiber and couplers...

Hello people, I'm trying to upgrade my home network and hopefully soon also my internet fiber to 10G. But first things first the LAN upgrade: I recently scored a good deal on a brand new SN2010 switch! This will be the core switch in my server rack. I bet most of you know but it supports (18)x...

I’m trying to configure a 10Gb fiber link between my two ESX and my TrueNAS Scale. I configured all my IP address correctly (subnet/netmask) but I’m unable to ping the destination interface. As the connection are direct between both machines, vlan is not configured. My first idea is to think my...

Hello, I have a question regarding advantages and disadvantages of two different network topologies I am taking in consideration. The description and illustration below are simplified and does not show each detail like VLANs. I am upgrading my home network. Today PC 1 and Server already are...

Hi All, Altice just rolled out fiber in my area (NJ) and I have been searching for a way around using their crap ONT/Gateway AIO. From what i've read, you need to keep the provided hardware and double NAT the network.. This isn't an optimum *pun intended* solution for me. So here is what I am...

It's quite hard to believe, but I couldn't find any information about creating a 40 Gbit home network. My issue is simple: I live in a 3 room apartment. Since I need the 40 Gbit connection between the rooms, a DAC solution is out of the question - since the distance between the rooms is approx...

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...

Hi there, I was wondering wich cards should I buy. Stumbled across a pair of Mellanox ConnectX-2 on the ebay for 99€. My goal ist using them with my Windows 10 Workstation (Threadripper 1900X, MSI X399 Carbon AC build) and my Homeserver (Xeon E5-2620v3 on SuperMicro X10SRi-F). Just a single P2P...

Hello, My wife and I have a white box running freenas and a dell poweredge R710 running a few VMs for backups, plex, and misc other tasks. After we added the R710 I started to realize the limitations of our Verizon fios router and began to research alternatives that would enable me to run...

Hey all, I used the instructions to cross flash two HP Connextx-3 cards QSFP to Mellanox MCX354A-FCBT's. I then installed two Fiberstore (FS) QSFP-BD-40G modules into one card configured as dual Ethernet. No dice, the link won't come up and the lights on the card stay off. Things I have...

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...

Probably noob question: Do all SFP+ NIC accept Fiber Transceivers? I want to buy a few 10G NICs and use a fiber SR Transceiver. Saw the threads on the OEM Mellanox, but couldn't figure out if they use copper or Fiber transceivers.

I'm relatively new to 10G Ethernet. I've got Intel X710-DA4 cards in three servers and have been directly connecting them to each other (no switch so far) with 3 meter passive SFP+ DAC cables and everything has been working great. (I started with an Intel DAC cable but then found the ones from...

I had to build a temporary server for a client earlier this year to replace a broken one and have one until his built to order one was delivered and setup. All the parts where new at time of build (except the RAID card I grabbed that out of another server) and less than a year old (was...

Hello, I have a Chelsio S320E 110-1082-31 dual port 10GBps PCI-E FC HBA. I am currently working on setting up a 40GBps lab, so cleaning out some older hardware. (Many RAID cards coming soon)! $50 +actual shipping (I'll throw in a gift!) $50 +actual shipping (I'll throw in a gift!)
