Price.
10Gb Switches are expensive. Most places are fine with 1Gb switches using aggregation. |

Right now, 10g is backbone territory. (have you ever priced enterprise grade networking gear?
 )We're seeing mostly Gig to the desktop in Corporate Land, but for most purposes even that is still borderline overkill. |

In addition to what has already been said, 10Gb over twisted copper (the -T variant) sucks.
Actual file transfer speeds over twisted copper drop by about 70% due to retries. Performance gets worse as the cable gets longer. For actual 10Gbit performance, use optical cable or shielded copper (usually uses CX-4 connectors). Passive copper cables with SFP+ connectors will also work, though are not optimal. |

I just blew about $15k on an 8 port 10g switch. Thats why.

Did the switch have to be a particular make/model with L3 management? An Extreme Networks X650 (24-ports) can be had for under $20K, plus SPF+ optical modules. ...and yes, it does wire-speed quite well! Quoted:

Went with the cisco 4900M with dual PS and added an 8port 10gbase-t half card. So I guess technically I have 16 10g ports. -Foxxz |

As others have stated, the price of 10Gb is keeping it firmly in backbone territory. We just upgraded the interconnects on our 6500s (VSS) to 10Gb, and even that is overkill at the moment.
The other reason is the complete lack of necessity. We still use 100Mb to most desktops these days (althought that pendulum is finally starting to swing) and we rarely see high utilization. The desktops that have converted to gigabit never see above 10-15% utilization. There is simply no reason to run 10Gb to the typical desktop. What the heck would they do with it anyway? Your WAN speed and the disk speed on your file servers would become your bottleneck. |

Some of the newer server platforms that are either already on the market or soon-to-be-released have embedded 10GbE ports, so it is becoming more common.
Desktops? That'll be a while. Meta4 brings forth a couple great points: - data throughput to the disk subsystem is the limiting factor within the computer platform - data throughput to the WAN (wide area network, or Internet) is the limiting factor everyplace else. Even intranets (networks within a company) are "slow" in this sense. 10GbE does make a lot of sense in server applications where the data stays mostly in RAM, avoiding the limitations of disk storage. The large search-engine services (Google, Bing, etc) and other active database systems use this methodology. These apps are also distributed across many individual systems to allow for LOTS of RAM and provide many CPU cores. |

Sorry, I just have to smirk since if I had 10gig to the desk my WAN connection wouldn't be the bottleneck.

Until you add VM clusters and Massive RAID arrays to the mix. Which puts us firmly into backbone territory. A few years ago 1-GbE was used for backbone only, and it was just a few of the faster intranets that were running at 100Mbit. I expect 10-GbE to eventually migrate to the desktop, just not "soon". Anyone remember the horrible problems getting 1-GbE running reliably on CAT-5 cabling... even long after the specifications were finalized and product was on the market? It was ugly for a while, and now it is ubiquitous. I suspect we will need to replace CAT-5 (or even CAT-6) with fiber to make it work well, which is a barrier for adoption ($$). |

Tbh, I've had more problems with 100bT than 1000bT, Cisco and Sun got in a bitch fight about how 100bT autoneg worked, and would consistently duplex mismatch unless you locked both sides. 1000bT autoneg works *great*, only problems I've ever seen are 1. shitty cables 2. when you *do* try to lock duplex, sometimes it causes issues |
