Abstract

The concepts proposed by Green IT have changed the priorities in the design of information systems and infrastructure, adding to traditional performance and cost requirements, the need for efficiency in energy consumption. The approach of Green Cloud Computing builds on the concepts of Green IT and Cloud in order to provide a flexible and efficient computing environment, but their strategies have not given much attention to the energy cost of the network equipment. While Green Networking has proposed principles and techniques that are being standardized and implemented in new networking equipment, there is a large amount of legacy equipment without these features in datacenters. In this panel, it will be presented the basic principles proposed in recent works for power management in legacy network equipment, and proposed its use to optimize green clouds.

Green cloud computing aims at a processing infrastructure that combines flexibility, quality of services, and reduced energy utilisation. In order to achieve this objective, the management solution must regulate the internal settings to address the pressing issue of data centre over-provisioning related to the need to match the peak demand. In this context, we propose an integrated solution for environment, services and network management based on organisation model of autonomous agent components. This work introduces the system management model, analyses the system's behaviour, describes the operation principles, and presents a case study scenario and some results. We extended CloudSim to simulate the organisation model approach and implemented the migration and reallocation policies using this improved version to validate our management solution.

Cloud computing and other highly virtualized data center applications have placed many new and unique requirements on the data center network infrastructure. Conventional network protocols and architectures such as Spanning Tree Protocol and multichassis link aggregation can limit the scale, latency, throughput, and virtual machine mobility for large cloud networks. This has led to a multitude of new networking protocols and architectures. We present a tutorial on some of the key requirements for cloud computing networks and the various approaches that have been proposed to implement them. These include industry standards (e.g., TRILL, SPB, software-defined networking, and OpenFlow), best practices for standards-based data center networking (e.g., the open datacenter interoperable network), as well as vendor proprietary approaches (e.g., FabricPath, VCS, and Qfabric).

In recent years, there has been intense focus on increasing the energy efficiency of IT infrastructure. We advocate the need to consider energy consumption holistically over the entire lifetime of these devices. Life cycle energy considerations include a number of factors, of which operational energy consumption is just one. Of all the IT components, networks have received relatively little attention when it comes to energy efficient operation, and even that has been too focused on operational power consumption. In this article, we describe the challenges relating to life cycle energy management of network devices, present a sustainability analysis of these devices, and develop techniques to significantly reduce network operational power. A distinguishing feature of our work is that it is applicable to legacy devices, and as such can be deployed now, as opposed to waiting for new standards and products to be developed.
