Cost and Interoperability of SFP+ and 10G Base-T
While 10GBASE-T switches have been available since 2008, and as an add-on for server platforms, 2012 saw vendors begin to ship server and storage devices with 10GBASE-T LAN on motherboard (LOM) technology. As a result, more than a half million 10GBASE-T server ports shipped in 2012.
As this trend continues, the shipment of 10GBASE-T ports is projected to reach upwards of 5 million for 2013. The increase in proliferation is helping to drive down the cost of 10GBASE-T technology.
SFP+ DAC solutions available from switch vendors are often proprietary and cost more than SFP+ DACs and category 6A patch cords from cabling vendors. With 10GBASE-T rapidly becoming the de factor LOM technology, the use of SFP+ can means an additional cost of adapters for the servers. In comparing one of the latest SFP+ and 10GBASE-T ToR switches, the cost of 10GBASE-T ranges from 20% to 40% less.
SFP+ and 10GBase-T Price & Cost Comparison
10GBASE-T also has the advantage of being an interoperable, standards-based technology that uses the familiar RJ45 connector and provides backwards compatibility with legacy networks via auto-negotiation. The ability to auto-negotiate between 1 and 10 gigabit speeds allows 10GBASE-T server upgrades to occur on an evolutionary, as-needed basis. SFP+ solutions do not support auto-negotiation and are limited with little or no backwards compatibility.

As a standards-based, category 6A twisted-pair technology, 10GBASE-T can offer more design flexibility using a structured cabling approach for longer distances of up to 100 meters, as well as shorter ToR switch-server connections using category 6A patch cords.
A structured cabling approach means that Category 6A cables can be field terminated on patch panels to any length for clean, slack-free cable management.
SFP+ direct attach cables (DAC) offer less than a 10 meter distance, and they are factory terminated and must be purchased in pre-determined lengths. SFP+ active optical cables (AOC) can support longer distances up to 100 meters, but at a much higher cost and with the same limitations as SFP+ DAC for point to point connections.
