One of my clients is getting a server that is not going to immediately have 10GigE but will probably have it in the not too distant future. Which of the following 10GigE cards from Dell would be most suitable? Note that the 10GigE switch is yet to be purchased. Some of these cards appear to use fiber and some use twisted-pair. Obviously buying a network adapter now is going to constrain the choice of switches in the future. Any suggestions?

I think that: Fibre usually means long distances 400m to 10Km. Direct attach is very short connecting SFP+ slots together 6m? 10G Base-T is Cu (Cat -6a needed for full 100m range) https://en.wikipedia.org/wiki/10_Gigabit_Ethernet#10GBASE-T but Cu is usually cheaper all round and gets cheaper. I believe it is still pretty hot but expectations are it will get cheaper/cooler as technology improves in the next few years. So if you are just connecting machines around an office - go Copper - if you are terminating a external link from another building/site- go SFP+ Often the bigger switches will be mostly Cu base-T with some SFP+ for the main connecting links. Some run Linux! https://cumulusnetworks.com/cumulus-linux/overview/ Interested in other opinions. Andrew

I'm curious about the "$6/week-1" thing. Does your hardware supplier offer hire-purchase or something? (I think I've rolled out 10G NICs before, but I don't remember the details. I'm pretty sure they were Intel and they Just Worked. Don't remember what connector was used.)
It's a cut and paste from the Dell web site. On 5 July 2016 5:06:07 PM AEST, "Trent W. Buck via luv-main" <luv-main@luv.asn.au> wrote:

Hi Russell, Not sure which machine type you are looking at but the R-series server normally come with 4 x networking ports on the back of them. You can get 2x 1G ports and 2x 10G ports. I would say the thing to look for is just having an SFP+ port. This way when the time comes you can make the call to use either Fibre, Cat 6 or Twinax cabling as you just need to get the right Module for the first two or the Twinax will plug directly into the port.

Thanks for the suggestions everyone, they will be useful in future and hopfully be useful for other people on the list. We ended up running out of time and just ordering a system with the default Ethernet options as it's surely at least a GigE port and it will be initially deployed in a situation with only a single switch port. This isn't ideal, but it's one of the things that happens when working in the small business segment. Clients can go rapidly from not having money for new hardware to urgently needing equipment for a new large project. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
