SFP+ Passive DAC für 10 Gigabit Ethernet und Fibrechannel

10Gtek's SFP+ Passive DAC are suitable for very short distances and offer a highly cost-effective way to connect within racks and across adjacent racks. SFP+ cables offers a low cost SFP+ solution. SFP+ directly attached twinax cable assemblies supports 10 Gigabit Ethernet, 10 Fibre Channel, and other industry standards. This cable is available at lengths from 0.5m to 15m.3 Meter 10GbE SFP+ passive, Direct Attach Copper Cables provide 10-Gigabit Ethernet connectivity with any SFP+ enabled port.Are all For Intel Ethernet SFP+ Passive DAC created equally? The answer is no. There DAC CABLE two types SFP+ DAC cable: Active and Passive. Scientific Computer has a good article listing SFP differences between active and passive cables.You can see here three different cables. The one on SFP left is the Brocade active cable.The middle is the Juniper passive cable, and the one on the right is a Cisco passive cable.You can see the contact pad difference between the active and passive cables.I am currently in the process SFP+ implementing Juniper EX4500 switches to deliver 10GE connectivity to our ESX host servers.During this process we decided to go the route SFP+ direct attach copper DAC cable to save money.Fixe 10Gigabit Kupfer-Direktlinks mit SFP+ Passive DAC erm?glichen die extrem kostengünstige (~ € 100,- pro Link!) und robuste Verbindung zweier 8G oder 10G Ports im High-Performance-Computing (HPC). Gerade in Rechenzentren mit einer Vielzahl von 10G-Verbindungen mit Distanzen <10m k?nnen diese SFP+ Kabel die Kosten einer Switch-Switch Connection im gleichen oder benachbarten Rack auf den Bruchteil der Kosten einer optischen Fiber-Infrastruktur reduzieren.
