Immediately after the standard of 10Gb Ethernet was ratified, numerous large companies began to apply it straightly to the central field of their business, data centers, and server farms for the purpose of supporting bandwidth with higher speed and some crucial applications. With the advancements in 10GbE technologies, the increased requirements of bandwidth, and the growth of enterprise applications in recent years, the influence and usage of it are no longer limited within merely enterprise but has stretched to mid market networks as well. As the deployment of 10GbE becomes increasingly popular than before, ten things are really crucial to realize the best use of it.
10GbE and the Server Edge to Achieve Better Efficiency
Enterprises usually work out to consolidate servers so that there is more space and power left to optimize their data centers as well as sever rooms. And this process often contains two steps: to combine the applications to fewer servers and to realize server visualization. The server visualization, which depends on networking and storage largely, enables some applications and operating systems on a single sever thus to make the best use of the processing power and resources.
10GbE SAN vs. Fiber Channel
As one of the three types of storage in a network, SAN(Storage Area Network) obtains much flexibility when comparing with the other two, and severs as a better solution for both data centers and computing applications. However, only with high expense and specialized staffs can the SANs with Fiber Channel be well-equipped in large companies. Moreover, The iSCSL, as a new standard, helps to make 10GbE an appealing SAN interconnect fabric which can compare to Fiber Channel. The 10GbE performs well by reducing the cost, enhancing server management and improving disaster recovery.
10GbE and the Aggregation Layer
Compared with Gigabit Ethernet aggregation, the 10GbE use less fiber strands which is more cost-efficient. Besides, because of its greater capacity, the 10GbE thus can support large streams that generated by applications. The most important is that, by applying 10GbE, it can enable a longer deployment periods so as to reduce the bottlenecks. 10GbE and Fiber Cabling Choice
When deploying the fiber cable, there exists three important choices: firstly, the type of fiber cable that contains both the multimode MMF(Multi-Mode Fiber) and the single-mode SMF(Single-Mode Fiber). Secondly, the type of 10GbE physical interfaces. And thirdly, the 10GbE module form factors. Furthermore, If the type of the physical interface on both end of the fiber link is the same, form factor options can be inter operable.
10GbE and Copper Cabling Choices
Cooper cabling has been widely used for 10GbE since the standard of which advances at a rather high speed. For the time being there are three technologies for copper cabling with different price and capability and each of them has their own merits and demerits. For example, the CX4(10GBase-CX4), which is the first cooper standard in this field, is cost-efficiency as it enables a relatively low latency. And the SFP+ serves as the latest standard with low latency, small form factor and reasonable cost. As for the 10GBase-T, although it is promising, the technology still needs improvements to reduce its cost, power consumption and latency.
10GbE and the SFP+ Makeover
By combining the SFP+ compatible connectors and the copper cable, SFP+ direct attach cables can achieve a solution which is low-latency, energy-saving and cost-efficiency. With DAC, 10GbE connections in short distances can perform for the best. As for ToR applications, DAC is used to simplify rack cabling and termination, it makes the management of cable easier and much more flexible.
In conclusion, if users take these necessities into consideration, what we discussed above can help enterprises and companies to achieve a better 10GbE deployment experience.
