标题: How Does CX4 Compare with 10GBase-R & 10GBase-T? [打印本页] 作者: wzt10gtek 时间: 2012-11-13 10:00 标题: How Does CX4 Compare with 10GBase-R & 10GBase-T? CX4 has numerous advantages over 10GBase-R (Fiber) and 10GBase-T (Cat-6). An optical connection would require (2) 10-Gig optical modules and a fiber patch cord to function. This has significant cost and power budget implications. Running 10-Gigabit Ethernet over UTP cabling like Cat-6 may sound promising, but it is plagued by power consumption and latency issues. Today's 10GBase-T chipsets are power hogs, as they require several Watts just to separate out signal noise. Here's a comparison of how CX4 stacks up in terms of power-consumption in a 50-server datacenter. Essentially, CX4 consumes 6x-20x less power.
