High performance gigabit Network to meet cloud computing application Dell FORCE10 S4810 test Report analysis

As cloud computing applications grow, more and more users are starting to deploy their million-gigabit networks. In order to help enterprises design, purchase private cloud, public http://www.aliyun.com/zixun/aggregation/13647.html "> Cloud data center structure, Lippis The Ixia Ethernet Data Center Switch Industry assessment was conducted by the FORCE10 and IP network test solution provider, and Dell's S4810 Gigabit switch performed well in the tests.

Dell Force10 S4810 Ultra-low latency, optimized for data centers

For Lippis/ixia testing, the Dell Force10 S series S4810 is configured with 48-port 10GB wire-speed switching. The Test team tested the S4810 48 Wan ports According to the RFC2544 specification. The results show that the average latency of the 2-layer communication is at least 799 nanoseconds, the highest is 855 nanoseconds, and the mean delay variation varies between 5 and 9.2 nanoseconds, and the consistent delay is present at the full speed and all packet sizes. The average latency range of the 3-layer communication is 796 nanoseconds, the maximum 868 nanoseconds, and the mean delay variation varies between 4.6 and 9.1 nanoseconds, and the consistent delay is present at all speed and in different packet sizes. In RFC 2544 throughput testing, S4810 also shows 100% wire-speed throughput, in other words, S4810 can distribute 2-and 3-layer line-speed traffic evenly to 48 10GB Ethernet ports without a single data switch. In the RFC 2889 specification-based congestion test, the S4810 switch shows 100% convergence forwarding capability at 2-tier and 3-tier traffic, and the test method is to S4810 a single 10GB port to 150% line-speed traffic without using hol (head-of-line Blocking, which means that the performance of the other ports is not affected when the 10GB port is blocked. The group tested the multicast performance of the S4810 switch based on the RFC3918 specification, resulting in 100% aggregation throughput configured for IP multicast in passthrough mode, 64-byte packet latency of 984 nanoseconds, 1024 bytes and 1280 bytes Packet latency of 1442 nanoseconds. So S4810 can be easily used as a medium and small distributed network gigabit core and large network access nodes such as Figure 1 and 2.

The test found that the Dell Force10 S4810 switch was very power-saving, with each port Wattsatis 4.03,teer value of 235. It should be noted that the higher the Teer value the better, because they show the ratio of work performance to energy consumption, each 10GB port annual electricity is 4.91 U.S. dollars, three-year tariff is expected to be 707.22 U.S. dollars, about its list price of 3%.

In summary, the Dell Force10 S-series S4810 is a high-performance 10/40 GBE switch that can be deployed in Web 2.0, HPCC, fast trading, iSCSI storage, or other sensitive business that requires ultra-high bandwidth and ultra-low latency Achieve ultra-low latency and high-density 10GbE switching networks. S4810 adopts the non-blocking straight-through switching architecture, which can provide line-speed L2 and L3 forwarding capacity at ultra-low latency, thereby maximizing network performance. The compact S4810 design provides 48 dual-speed clutch GbE (SFP) ports plus the industry-leading density of the 4-GbE-QSFP uplink to save valuable rack space and simplify the Gbps migration in the datacenter core (each GbE QSFP The uplink can support 4 GBE ports with the help of a branch cable. Powerful QoS features, combined with data center bridging (DCB) support (provided by future software enhancements), can fully support future software development, making S4810 an ideal choice for iSCSI storage environments. In addition, S4810 incorporates several architectural features that optimize data center network flexibility, efficiency, and availability, including the Dell Force10 Virtuallink Trunkig VLT and stacking technology, suitable for a cold/hot channel environment, and the ventilation design for either front or rear air supply As well as redundant hot-swappable power supplies and fans. S4810 also supports the Dell FORCE10 Open Automation Framework, which provides advanced network automation and virtualization capabilities for virtual data center environments. The Open automation framework includes a set of interconnected network management tools that can be used in combination or used alone to build a more flexible, usable, and manageable network while reducing operating expenses.
