<div dir="ltr">Lincoln,<div><br></div><div>I know you live in vendor world, but most of us live in the real world. I work in a lot of networks, SP's, Enterprise... old and new.. and I almost NEVER come across equipment with 10GBase-T ports in them. I don't even recall the last 10GBase-T port I saw - and this is on a LOT of kit.</div>
<div><br></div><div>This very much sounds like the property people saying 'The market is going to increase and values increasing!' just to justify and push up their own sales.</div><div><br></div><div>I know Arista has 10GBase-T, in fast the first 48 port 10GBase-T switch I ever saw was an Arista. Don't misunderstand me... I think 10GBase-T is awesome and I recommend people consider it as a TOR over SFP+ anytime they have a number of ports to justify it... but few do due to the lack of portability of 10GBase-T - meaning you need those ports wherever kit is moved to, very few people are seriously considering it as a choice to deploy.</div>
<div><br></div><div>With cost, I am not talking about the SME crap... it is a hell of a lot cheaper to deploy 10GBase-T switches - the switches are a bit more expensive, but once you factor in SFP+ modules into a switch, the opticals are much more expensive.</div>
<div><br></div><div>I also meant to the vendor who replied about the 10GBase-T <-->SFP+ module possibility... and that making that, which would be consumed in VERY low numbers (my opinion) that the business case would be hard - for anything - made where the numbers shipping would be low.</div>
<div><br></div><div>Re switch availability... I live in a world of enterprise grade, and also mainstream vendors. Juniper has 1 switch (that I know), Cisco has a few line-cards and mostly higher-end Nexus models (2k - which are Fabric extenders, 5596T) and 6500 line-cards... the 4900 has some modules, but there is nothing (I think) in the Catalyst 3000 and below series.. in fact, even full 10G SFP+ is still rare at this level of switching.</div>
<div><br></div><div>Cisco and Juniper both still have no all 10Gb (SFP+) switches in the low end (EX2200, EX3200, C29xx, C3xxx) ranges, much less 10GBase-T.</div><div class="gmail_extra"><br clear="all"><div><div dir="ltr">
