    Mellanox ConnectX-3 interfaces disappear

    I'm trying to speed test some Mellanox ConnectX-3 dual port 40GbE NICs on my LGA2011 servers (using a Linux live USB, System Rescue CD) and I'm getting this weird behavior where the assigned interface/logical name disappears (i.e., en25ps0) when I connect a QSFP+ network cable to a port. If I...

    40 GbE with Mellanox ConnectX-3 in Ethernet mode?

    Can you get the 40 GbE speeds with a Mellanox ConnectX-3 VPI adapter in Ethernet mode or must it be in Infiniband mode? If the latter, can the required subnet manager software run in Linux or a docker?

    getting lost... local storage, FreeNAS+local storage or FreeNAS+DAS for VM storage?

    I'm about to add my 2nd VM host (ESXi) and I will being add more hosts in the near future, so I figured I need to consider piecing together some shared storage for the VMs. I've been searching for a couple of days now, but can't find a concrete answer - I understand local storage for VMs will...

    getting traffic via both 1 Gb and 10 Gb NICs with FreeNAS and ESXi setup

    I can't find any where to change path policies plus I don't think I'm using multiple paths (it's NFS).

    getting traffic via both 1 Gb and 10 Gb NICs with FreeNAS and ESXi setup

    I set up a ESXi (6.7 u3) datastore on a FreeNAS NFS share. The connection is 10GbE via a 10GbE switch. When running CrystalDiskMark to benchmark VMs' disk performance, the reads are going through each server's gigabit NIC and the writes are going through each server's 10GbE NIC. The 10GbE NICs...

    2U rackmount chassis with horizontal/full height PCI-e?

    Are there any 2U rackmount chassis out there that feature both vertical half height AND horizontal full height PCI-e/expansion openings similar to the chassis pictured below?? Or even 2U with just horizontal full height openings? P.S. - I have the chassis pictured, but it appears it's designed...

    Flex ATX won't fit 2U server case

    I picked up a Arndt 2U server case (D-216-WM-SAM01) from jameco.com and a Apevia ITX-AP300W flex ATX power supply to go with it. The problem is the power supply appears to fit/be the correct size, but the mounting holes don't line up (see attached photo). I'm not sure if this is a defect of the...

    reconfigure or new build?: Blue Iris and Plex combo box

    I currently have my Blue Iris build in a 1.5U rackmount case w/ Core i3-8100 & mini-itx mobo (full specs below). The problem is CPU temps is currently an issue as it's hitting 180+ degrees F - likely due to the lack of air flow (the front case fans are blocked by the RAM modules, the 1U CPU...

    cheap dual port 10 gbe NICs for most homelab OSes?

    By "10g of these", do you mean 10 GbE ConnectX-3's or 10 GbE ConnectX-2's?

    cheap dual port 10 gbe NICs for most homelab OSes?

    wow, I didn't know ConnectX-3's came down that low. I couldn't find dual port 10 GbE ConnectX-2's for less than $70 last year. Thanks!

    cheap dual port 10 gbe NICs for most homelab OSes?

    I seldom re-purpose my homelab equipment and servers. Having to work around my mix of 10 GbE SFP+ NICs not working with a particular OS is frustrating. Is there a cheap (eBay) dual port 10 GbE SFP+ card that is stable, works out of the box or requires little effect to get working with FreeNAS...
