    10Gb SFP+ card for PC to switch, Sonnet Presto Solo reviews?

    I would like to connect my PC RAID server to US-16-XG Ubiquiti 10Gb switch using SFP+. I would prefer only a single port, and would like it to be PICe3.0 X4, so as to not to unduly burden my expansion slot requirements. PCIe X8 just isn't needed for a single-port card on PCIe3.0. But if the...

    Connecting 10gb - choosing cable and modules question

    My question is regarding connecting a few ConnectX-3 devices (SFP+). For my home lab, I am looking to upgrade the connections on 3 systems, all linux. They are already connected at 1gb ethernet and I would like to get them all to 5gb or 10gb if possible. I mention 5gb first because I am not...

    [EU] Looking for cheap SFP+ switches and QSFP+ backbone switch

    I have a few ConnectX-3 cards with dual QSFP+ ports on each and I'd like to have their capacity available for a local LAN party (36 total 1G ports required) without breaking the bank. The problem is the QSFP+ enabled switches common in the US are either much more expensive in the EU or just...

    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...

    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...

    10gbe IPoIB (Infiniband) bridge

    Hello all, I was thinking, for my living room where I have quite a few servers running (silent !), to do a custom 10gbe IPoIB setup. In my lab room I could use the Voltaire 4036 (non-E version unfortunately) which I still need to find a way to silence. It's way too noisy even for the server...

    SFP compatibility on SFP+ nic?

    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...

    10GB+ ethernet workstation heat

    For those running server 10/40GB Ethernet adapters in their desktop/workstation setups designed for low airflow, how did you choose to cool these cards designed for high airflow cases? PCI slot coolers? oversized heatsinks? Re-purposed CPU coolers? water cooling?

    Hey! I am in the process of getting a proper 10gbit vaai supported storage solution for my home lab. I am considering the QNAP TS-831X, as it has 2x sfp+ built-in, and vaai support + vsphere plugin. Not sure if the performance will be good enough though. So, I found some hardware I might...

    Intel X520-DA2, HPE 1950-24G-2SFP+-2XGT & DAC?

    Hi, will that combo work? The 1950 manual mentions DAC for the SFP+ ports only for purposes of stacking. Googling, around, I could not find a lot of information, other than that HP switches may be picky in terms of which DAC cable to use... Any hints? Thanks!
