subject: Sina Integrated In A Data Center Room Layout Transformation Program - Cabling - Smart Home Industry [print this page] HC Network Security Sina is the largest Chinese portal website, there are already more than 100 million people registered users. In the 2008 Olympic Games, the SINA network broadcast traffic ranking first nationwide. Sina search is also a major Chinese information retrieval tools. All of the data center Sina capacity, bandwidth and processing power make high demands. Sina must continue expansion of the existing network size, the current Sina has been building throughout the country dozens of data centers. But taking into account operating costs, while also upgrading Sina original data center. Sina very early example has most of the server's Fast Ethernet Gigabit Ethernet card replaced, but now the transition to Gigabit. In the core switching and routing, part of the original data center systems have been unable to meet existing demand, mainly in two aspects, 1) lower density of the original capacity of the system, taking up a lot of space 2) the bandwidth of the original has been not use, so it is necessary to add new channels or increase the channel bandwidth. The Sina cabling in a data center room transformation focused on replacement of the original core purpose is to improve space utilization, while increasing the number of core fiber-optic links. At the same time the next generation of Ethernet has emerged as prototype, so the upgrade process must also be taken into account in future development. This transformation is a model project, Sina other domestic data center room will gradually transform this as benchmarks.
The data center has two floors, three floors and two floors, each floor decorated nearly 300 server rack. Every 7-8 months to configure a column header rack cabinet. Each floor has a core switching and routing region (including the main wiring area). Server cabinets and counter the first by Cat6 twisted pair wiring between the levels. Out the first counter to the core of the exchange, and 2 floors of the core fiber optic interconnection between regions through the OM1. All light wiring are used 1HU height of 24 core LC patch panel, while also configure the level of cable rack management. Such a structure greatly limits the network bandwidth. Also wasted a lot of room. The transformation process, Rosenberg products according to the characteristics of the mainstream market while taking into account the future to upgrade the capacity of next-generation Ethernet networks, data centers with Sina actual situation of the proposed reform program.
To reconstruct the floor is roughly two to remove the second floor of the core switching, routing, and the main wiring area, the core devices (switching and routing) all moved to the third floor, replaced the second set in the floor a focal point. Counter the first two floors of the uplink cable to connect the hub to the floor by three of the main wiring area. Counter the first two floors of the 12 cores used in all pre-connected MPO-MPO OM3 fiber uplink to the focal point. Focal point of more than 40 columns from the first cabinet line-core cable to connect over 500 jump 144 core OM3 received four pre-MPO-MPO cable connection, the unity of uplink to the core of the three floors of the main wiring area. Focal point of the optical fiber wiring with a high degree of high-density patch panel 5HU. With the MPO panel, 2 rack space previously required the light wiring, and now only use 5HU height.
