Ubiquiti / Dell switch compatibility issue:

(http://www.newegg.com/Product/Product.aspx?Item=N82E16833997115)Oh, that's not fiber.. that's copper Twinax. Twinax isn't something you generally do between differing models of switches. Because you need compatible SFPs on each end.

So what's the best way to make a 10G/10G connection between the 2 switches? Should I get fiber and cross it over?

These are the only supported options on the Unifi.. for 10GB.
10GBase-SR
Fiberstore SFP-10G85-3M MMF
DAC/TwinaxAddon SFP-10G-PDAC1M-AO
Juniper ex-sfp-10ge-dac-1m - (Amphenol 584990001 Rev A)
This is a 10g DAC that appears to link up at 1g when both ends are plugged into the two SFP slots of the ES-24-250W
I haven't tested sending traffic over this cable, as I only have one ES-24-250W, and Juniper equipment wants to link up at 10g when using this DAC
MikroTik S+DA0001
Molex 74742-0001 -
10GBase-SR is what I would recommend. Get fiber between the switches that seems to be one of the best ways. How close are the switches can you do 10G over twisted pair?
I've never heard of Twinax, which isn't unusual just interesting.
-
I'm using twinax to connect my servers to my backup storage, but the sfp+ adapters are connecting to the exact same Intel cards in both cases.

can you do 10G over twisted pair?- They're pretty much touching each other
- Yes you can, but these Dell's have no RJ-45 ports
Fiber seems to make the most sense for this connection.

Yep, if you are going to invest in the modules anyway fiber is the way to go.

Gone are the days when you could go into CompUSA and pick up a part like this, unless you guys have a few cards around the office or have a few connections to get equipment to set this up...
Seems like a few more days before this'll be up.

Especially since it is a holiday week.

I thought they had it up already? Seems like I remember @scottalanmiller posting pictures of random OSes being installed.
-
From what this post is saying is that it's not up with a 10GB network connection.
I'm just guessing that they're wanting to make some changes to the original configuration.
-
Sorry if this is confusing anyone. Yes, the cluster is up and functional, but we can only get 2 nodes on the LAN at a time until we get the Dell switch to interface with the Ubiquiti. The Ubiquiti has only 2 SFP+ ports. In order to get a 3rd, we need to connect the 2 switches so that all of the ports on the Dell can have LAN access through one of the ports on the Ubiquiti.

Nahh, Just order them off Amazon with Prime.
