Re: 10GBase-t switch
Another option you can look at is TwinAx copper cables. There are lots of products that support it including - TurboIron24X from Brocade/Foundry, Arista boxes and BNT boxes. Jack
Re: 10GBase-t switch
I was talking to the Brocade SE and he mentioned that TurboIron 24X will support Full L3 including multicast routing along with advanced L2 such as stp groups, vlan groups, MRP, ..etc

RE: 10GBase-t switch
I will likely never buy or recommend Foundry equipment again. In a previous gig, a HPC enviorment, they caused us many problems, support was horrible, and thier 10Gbit kit was the pits when it was first released (no idea how it is now or what they offer, its been 5 years since. burnt once, twice shy). We replaced most all our Foundry L2 gear with HP 8212s which met our expectations. Brocade is the king of license gouging, it is no surprise they want money to view a pdf. Force10 and Extreme are both having sales this month on 24 port 10Gbit switches, $20k off almost. -g From: David Hubbard [dhubb...@dino.hostasaurus.com] Sent: Thursday, March 11, 2010 1:31 PM To: nanog@nanog.org Subject: RE: 10GBase-t switch From: Malte von dem Hagen [mailto:m...@hosteurope.de] Hi, Am 11.03.10 16:29 schrieb Dylan Ebner: Do the Arista switches support netflow? nothing about it in the datasheets, and regarding documentation: A registered account and a valid support contract is required to access the Software Download and Documentation section of the website.

RE: 10GBase-t switch
+1 for the Arista boxes. We are a pure Cisco shop and looked at them to start replacing some gear where it made sense. We didn't buy them because they didn't do Rapid-PVST+ at the time. Yeah I know that's a Cisco-centric thing, but they were tentative on implementing it but the timeline just didn't meet our needs. Observations: Seriously knowledgeable technical/dev guys and I know for a fact that a pile of them came from the old Cisco 4K team back when the 4K's were walking circles around the 6K team in terms of innovation. If it make sense they are willing to implement features and they did so for us even though we were a demo. We had a question way back when distance limitations with SFP+ CU/CR/DA 5 meter cables and they actually got us on the phone with folks at Intel that normal people just don't have access to. Even though we don't have any Arista kit, their initial efforts left an excellent impression on us. P.S. They will give you temp access to the site if you ask but I too agree that it should be an open model.

I have to agree the Arista is a great box at a great price (comparatively). I was really impressed with the performance in our testing for top of rack switches. The Juniper EX3200 with 10GigE uplink card works really well too but you are limited to 2x10GE ports per switch. We have a couple of them deployed in that configuration in our closets.
