When it's time to switch over to a high-performance data centre solution to cope with its explosive growth in business, China's Yihaodian, the country's largest online supermarket, decided to opt for one from Brocade.
After four years of operations, Yihaodian is fast outgrowing its data centre infrastructure. According to Jason Han, CTO, it "needed to replace it with something that had the performance, scalability and reliability to cope with rapid growth for several years to come."
Yihaodian decided to deploy Brocade MLXe Series routers with multi-chassis trunking in its data centre core to achieve high availability and scalability, while reducing complexity and optimising performance.
The Brocade MLXe-4 Core Routers deployed by Yihaodian each have 1.92 terabit per second switching fabric capacity, ensuring that all the 10 Gigabit Ethernet (10 GbE) connections to the network core are handled at wire speed.
The Brocade MLXe-4 routers are linked over multiple 10 GbE connections using Multi-Chassis Trunking (MCT) to create a single logical switch that dynamically load-balances traffic from access layer switches with multiple connections to the core devices.
In addition, Yihaodian has deployed Brocade FCX Series Switches to provide wire-speed 1 GbE access to its application and database servers. As with the core and DMZ networks, these switches are combined into a single logical device with up to eight Brocade FCX 648 switches providing 384 access ports and multiple 10 GbE uplinks to the core.
To handle the high-volume traffic between the core and the data centre's Internet-facing demilitarised zone (DMZ), Yihaodian has deployed Brocade ICX 6610 Switches that offer chassis-like performance and reliability in a stackable form factor. Multiple 10 GbE uplinks to the core enable a highly scalable solution designed for non-stop availability.
The new solution is also meant for future growth. If the data centre's capacity outgrows the new routers, the core could be further scaled by adding another chassis to the MCT virtual switch cluster.
Founded in 2008, Yihaodian has logistics centres in five of China's largest cities -- Shanghai, Beijing, Guangzhou, Wuhan and Chengdu -- that stock more than 270,000 products and provide same-day and next-day delivery services. Its customer base tripled from 2010 to 2011, and last year's average daily order volume was six times higher than that of 2010.
The company, in which Walmart raised its stake to 51 percent earlier this year, chalked up sales of RMB2.7 billion (US$429m) in 2011, which was 335 percent higher than in 2010.
