"By 2015," predicts Vlasov, "there will be more optical links in one high-performance data center than in all telecommunications links worldwide".
In the high performance data center, compute density per cubic centimeter is often the name of the game.
Flash memory, which provides more speed and throughput with far lower energy consumption, is already filling the void in high performance data centers.
Today, that trend continues both through real estate development and investment with a particular focus on high performance data centers, healthcare & life science research and communications.
Godfrey has developed novel architectures and systems for Internet routing, data-center networking, high-performance data transport and network data-plane verification.
In order to meet high performance and reliability requirements, the data center network is usually constructed of a massive number of network devices and links to achieve 1 1 oversubscription for peak workload.
Figure 5 Message passing performance on a lossless data center network.
In order to provide high performance service with strong reliability to users, the data center network (DCN) architectures are usually over-provisioned and constructed aggressively with large number of switches and links to achieve high-capacity and high fault tolerance [3].
These experiments show that the message delays can have a lot of variation and spikes of high latencies can be expected for cross data center network traffic.
In order to achieve better network performance, recent studies have proposed to tailor data center network traffic management in different aspects, devising various routing and transport schemes.
In the simulations, the performance of the FP and EAR is compared with ECMP routing which is traditionally used in data center network topologies and achieves load balance and high network performance.
