Optimal VDC Service Provisioning in Optically Interconnected Disaggregated Data Centers

Abstract-Virtual Data Center (VDC) is a key service in modern Data Center (DC) infrastructures. However, the rigid architecture of traditional servers inside DCs may lead to blocking situations when deploying VDC instances. To overcome this problem, the disaggregated DC paradigm is introduced. In this paper, we present an Integer Linear Programming (ILP) formulation to optimally allocate VDC requests on top of an optically-interconnected disaggregated DC infrastructure, aiming to quantify the benefits that such architecture can bring when compared to traditional server-centric DCs. Moreover, a lightweight Simulated Annealing (SA)-based heuristic is provided for scenarios where the ILP scalability is challenged. The obtained numerical results reveal the substantial benefits yielded by the resource disaggregation paradigm.

Abstract-Modern high-performance Data Centers are responsible for delivering a huge variety of cloud applications to the end-users, which are increasingly pushing the limits of currently deployed computing and network infrastructure. Alloptical dynamic data center network (DCN) architectures are strong candidates to overcome those adversities, especially when they are combined with an intelligent software defined control plane. In this paper, we report the first harmonious integration of an optical flexible hardware framework operated by an agile software and virtualization platform. The LIGHTNESS deeplyprogrammable all-optical circuit and packet switched data plane is able to perform unicast/multicast switch-over on-demand, while the powerful Software Defined Networking (SDN) control plane enables the virtualization of computing and network resources creating a virtual data center (VDC) and virtual network functions (VNF) on top of the data plane. We experimentally demonstrate realistic intra data center networking with deterministic latencies for both unicast and multicast, showcasing monitoring and database migration scenarios each of which is enabled by an associated network function virtualization (NFV) element. Results demonstrate a fully-functional complete unification of advanced optical data plane with an SDN control plane, promising more efficient management of the next-generation data center compute and network resources.

On the benefits of resource disaggregation for virtual data centre provisioning in optical data centres

Virtual Data Centre (VDC) allocation requires the provisioning of both computing and network resources. Their joint provisioning allows for an optimal utilization of the physical Data Centre (DC) infrastructure resources. However, traditional DCs can suffer from computing resource underutilization due to the rigid capacity configurations of the server units, resulting in high computing resource fragmentation across the DC servers. To overcome these limitations, the disaggregated DC paradigm has been recently introduced. Thanks to resource disaggregation, it is possible to allocate the exact amount of resources needed to provision a VDC instance. In this paper, we focus on the static planning of a shared optically interconnected disaggregated DC infrastructure to support a known set of VDC instances to be deployed on top. To this end, we provide optimal and sub-optimal techniques to determine the necessary capacity (both in terms of computing and network resources) required to support the expected set of VDC demands. Next, we quantitatively evaluate the benefits yielded by the disaggregated DC paradigm in front of traditional DC architectures, considering various VDC profiles and Data Centre Network (DCN) topologies.Peer ReviewedPostprint (author's final draft
