Abstract
Energy consumption for datacenter has grown significantly and the trend is still growing due to the increasing popularity of cloud computing. Datacenter networks (DCNs), however, are starting to consume a greater portion of overall energy in comparison to servers used in datacenters due to advanced virtualization techniques. On the other hand, devices in a DCN often remain under-utilized. There are various DCN architectures. This paper proposes an approach called Green Spine Switch Management System (GSSMS) for Spine-Leaf topology based DCNs. The objective of the approach is to reduce energy consumption used by the network for a Spine-Leaf topology-based datacenter. The primary idea of GSSMS is to monitor the dynamic workload and only keep Spine switches that are necessary for handling the current network traffic. We have developed an adaptive management system to control the number of Spine switches in a Spine-Leaf DCN for efficient energy consumption. Further, we have performed extensive simulation using CloudSim for a number of scenarios. The simulation results demonstrate that our proposed GSSMS can effectively save energy by as much as 63 % of the energy consumed by a datacenter comprising a fixed static set of Spine switches.
Highlights
The usage of third party datacenters for provisioning of services is becoming more widespread
For the 100 % First Utilization Threshold (FUT-H) case, there is no difference in average number of active Spine switches (ANASS) for the four traffic patterns because 100 % is too high and Green Spine Switch Management System (GSSMS) never has a chance to increase the number of active Spine switches during the simulation
Conclusions and future directions This paper proposed GSSMS to save energy consumed by the Datacenter network (DCN) using the Spine-Leaf topology which has received increasing attention in practice
Summary
The usage of third party datacenters for provisioning of services is becoming more widespread. The energy consumed by datacenters still remains substantial and it is important for datacenter service providers to minimize electricity usage for protecting the environment as well as for reducing operational cost. With over-provisioned servers and the supporting power infrastructure, e.g., cooling systems, that are used for handling (the temporary) peak workloads, datacenter devices typically remain under-utilized for most of the time. A preliminary report described the basic idea of a novel Green Spine Switch Management System (GSSMS) [20] for Spine-Leaf topology [5, 6] based DCNs. The aim of GSSMS is saving energy by dynamically controlling the number of active Spine switches and maintaining only a minimal set of active Spine switches that is necessary to handle the current workload.
