switch con porte sfp+ da 10Gb
Stavo guardando alcuni switch 1Gb con 2/4 porte SFP+ da 10Gb. Scrivono tutti porte da uplink/stacking, cioè dovrebbero servire per collegare altri switch e usare una banda fino a 20-40Gb tra i vari ...
Non preoccuparti, puoi italiano, inglese, tedesco, francese ... but easier to commmunicate in English here.

In general yes, there is non-blocking almost full wire switching speed on all 10G and 1G ports, any to any.
Not sure what Netgear switch model you have in mind.
For example the S3300
http://www.netgear.it/business/products/switches/smart/S3300-28X.aspx#tab-specifichetecniche
It has 24 normal port at 1Gb and 4 sfp+ 10Gb ports for uplink/stacking.
They only speak of "uplink/stacking", so instead you say you could set VLAN and other rules also on these 4 sfp+ ports? And communicate with all the other ports like if they were normal access port, even L2+ routing and so on?
Reason for my curiosity question was hat I was not aware of such a Netgear switch model with GbE plus four SFP+. On the GS728TX (and all four S3300 models), of the four dedicated 10 GbE ports are two 10GBASE-T, and two are SFP+:
Said that, all the 10 GbE ports are generic ports, available for any purpose at any speed (except of the new 2.5G and 5G MultiGig).
What I don't know is if Netgear does enforce the usage of Netgear SFP+ modules with a Netgear ID on this model line.Ok, so those 4 sfp+ are considered like normal ports (that can be used ALSO to uplink/stack), good.
So you think it could not work using a generic sfp+DAC cable? Maybe that ID thing could be a problem only with optical sfp+ modules?

As per the specifications I see there are just two SFP+ plus two 10GBASE-T ports - so not sure why you continue to talk of four SFP+ ports. Just want to avoid you are going to order something wrong 8-)

No experience with non-Netgear modules/DAC on this model line on my side.
