Under the 7250 section click the link for the post with detailed info, it has a series of commands that will full license the switch for free. :)

First post in this thread has all the info you need.

Sorry I missed this, this last year was bonkers and I didn't get to play with the switch at all after I got it! Looks like fodeesha answered the question for me though. Shame it doesn't have that flexibility, though with the 4x10g modules being so cheap it's not a huge loss.

The ConnectX-2 is a PCIe 2 card so I guess that's not it. I'm curious if maybe I put it in an electrically PCIe 1x slot or something. Though that wouldn't explain the asymmetrical nature of the problem.

If it's specifically built as a lab I'd think concerns about storage availability would be slightly less critical.

Could this (The PCIe limitation) explain some intermittent 10gbps networking speed issues I have on that box? I have ConnectX-2 cards in there and it randomly gets stuck at ~2.5gbps speeds in iperf in one direction only. (I can't remember if it's testing to/from that server that's the issue)...

I think having copper anywhere you want an endpoint that's not a PC/Switch is still a good idea. Also hard to do PoE over fiber. ;) One of my main purposes in getting a wired connection up to my second floor is that I can then punch ethernet up through the ceiling into the attic (I have a stub...

Found some info on the power consumption: https://www.servethehome.com/dual-intel-xeon-e5-2620-v1-v2-v3-compared/ Should scale across the different CPUs pretty reasonably. Across 4x CPUs v1 to v2 might be a worthwhile power consumption drop along with a bump in performance.

I'm capable of comparing the specs, it's more the practical side I'm curious about. v3 would take a new server correct? I believe that jumped to a new socket.

Hi all, My lab/NAS/Firewall setup currently consists of a Cisco C220 m3 and an Intel S2600gz system sold under the Penguin Relion badge (running stock Intel bios). Both have been rock solid stable with E5-2640v1 processors and IIRC 48gb of ram per. Both are running ESXi 6.7 and I have my...

I agree with your plan to run both SMF and MMF fiber for your edge switches/PCs. Fiber is cheap and which type is cheapest to get the connectivity you want with a given type of equipment seems super variable. I bought F/UTP shielded for my house. To simplify termination I ponied up for the...

So your endpoint connects to fw1 via the main port in question, but has an extra set of vlans setup as a secondary (normally inactive) uplink. Those vlans are configured on another switch port that's in a vlan with the 4g router. When you swap it, those vlans go active and your primary ones go...

I'm struggling to see why you'd configure the downstream device such that the switch has to constantly ignore traffic from it.

Thanks! I put an offer in. I love FS but unless I've got a bunch of stuff to order the shipping cost kills it.

I'm curious of these will do ethernet. Amphenol is high quality stuff. https://www.ebay.com/itm/81Y8093-IBM-Amphenol-Infiniband-1M-40Gb-s-QSFP-to-QSFP-DAC-Copper-Cable/333538768297?hash=item4da875b5a9:g:2O8AAOSwBiNeZBXz
