Today data center network operators often use traditional data center interconnect (DCI) approaches to connect multiple data center sites. However, while connected, these data centers still operate as islands. What enterprises and service providers that operate multiple data center sites really need is to unify all sites in order to enhance their business agility and resilience while improving operational efficiency. Achieving those goals requires a unified multi-site data center fabric that makes multiple sites look like a single programmable entity, enabling increased resource sharing, simplified workload migration, and mobility, and improved business continuity and disaster recovery.
The Pluribus Adaptive Cloud Fabric simplifies multi-site data center networking, seamlessly interconnecting geographically distributed locations into a unified network fabric. With a controllerless SDN architecture incorporating network virtualization for secure multi-tenant segmentation, as well as built-in monitoring and analytics for pervasive network visibility, Pluribus delivers the best network fabric for multi-site data centers.
Traditional data center interconnect approaches stop at the edge of the data center and do not inherently result in a unified network fabric across multiple sites. In contrast, the Pluribus Adaptive Cloud Fabric delivers much more than standard data center interconnect solutions. The Adaptive Cloud Fabric is based on the Netvisor® ONE network operating system and reaches deep inside the data center all the way down to every top-of-rack switch. It creates a fully software-defined overlay network, based on industry-standard VxLAN technology, over any wide area transport network technology and topology (including over traditional DCI transport solutions). This approach abstracts away distance and underlay network complexity, supports insertion into existing “brownfield” network environments and enables seamless connectivity among endpoints and resources located within any site in the fabric.
Benefits of a Pluribus multi-site data center fabric include:
- Comprehensive automation for simplified operations – Unlike any other solution, the Adaptive Cloud Fabric automates both the underlay network and overlay network virtualization with built-in monitoring and analytics. This enables dramatically simplified operations, from streamlined day 0 deployment and one-touch automated fabric-wide service and policy provisioning to end-to-end fabric-wide monitoring and visibility. The result is increased agility, lower operational costs, and more time for operations staff to focus on higher priorities.
- Cost-, space- and power-efficiency – The controllerless SDN architecture running directly on open network switches eliminate the need for multiple redundant controllers at every site, enabling dramatically better cost-, space- and power-efficiency – especially important for smaller data center sites.
- Secure network segmentation – Deep network segmentation across the data, control, and management planes supports secure multi-tenant data center services and isolates applications and untrusted devices, including Internet of Things.
- Pervasive visibility and insight – Built-in wire-speed monitoring, which requires no external hardware and has no performance impact, provides full visibility into physical and virtual networks – every port, every flow, every application, from start to finish.
Business Continuity and Disaster Recovery
A Pluribus multi-site data center fabric enables geographically separated data centers to easily participate in any form of business continuity and disaster recovery (BCDR) strategy. Unlike traditional data center interconnect approaches, the Pluribus multi-site data center network fabric allows all resources to appear as if they exist within the same “local” infrastructure. When the physical delineation between data centers is removed, critical business information can be backed up, replicated or accessed in real time and active-active or active-standby strategies can be implemented much more simply. In the event of failures or IT maintenance schedules, workloads can be easily moved or recovered in any location.
Capacity Planning and Resource Sharing
A Pluribus multi-site data center network fabric enables dynamic and virtualized processing to span across all available resources, regardless of location. This increases the utilization of each resource and provides a mechanism to monitor the utilization of local versus remote resources, providing an opportunity to add additional capacity in the most-needed locations.
Workload Mobility and Migration
Pluribus multi-site data center fabrics completely eliminate the boundaries between data centers and the resources that they house. Workloads can move among any sites in the fabric for capacity or availability reasons with no IP readdressing needed, and continue to be accessed from other sites as if they were local.
