Modern virtualized, distributed application architectures are placing profound new demands on the data center networks that serve them. Application performance itself is now highly dependent on the efficiency and resilience of the network connecting the application components.
IT organizations also need the flexibility to scale out their networks on demand to respond to immediate business needs without hard-wired technical limitations. Perhaps most importantly, mission-critical networks must ensure predictable application performance at any time, regardless of traffic volume. However, overbuilding data center networks to support the equivalent of a “100-year flood” is generally not economically feasible. IT departments need to find practical ways to strike a balance between resilience and flexibility on the one hand and over-engineering on the other.
Fabrics increase network utilization
Traditionally, network designers have built out large (and expensive) aggregation and core tiers in lockstep with connectivity growth in the access tier. With innovations at Layers 1, 2, and 3, Brocade® VCS® Fabric technology addresses key challenges in scaling out data center networks—keeping capital and operating costs linear as well as improving information mobility and application performance.
Brocade VCS fabrics enable users to:
Elastically grow Layer 2 domains with optimal network utilization through efficient, dynamic load balancing at Layers 1–3
Supply multiple active load-balanced paths and Layer 3 gateways for maximum resilience, network bandwidth, and scale
Improve virtualized application performance through better access to network bandwidth, reduced hop count, and reduced latency
Today’s data centers are undergoing a profound transformation due to shifts in application architectures and rising expectations with regard to IT service delivery. However, existing network infrastructure is largely static, making it difficult to respond to the ever-changing requirements that virtualized applications impose on the network.
Brocade VCS Fabric technology was designed from the ground up to address this paradox. While traditional, hierarchal Ethernet networks are complicated, inefficient and highly manual—which heightens the potential for conflicts and outages due to human error—Brocade VCS Fabric technology delivers unprecedented simplicity and automation and offers exceptional efficiency and fault tolerance.
Brocade VCS Fabric technology applies intelligent automation to fabrics, delivering resilient fabrics with multiple active gateways, all active links, and highly efficient load balancing at each network layer. Now IT organizations can elastically scale their VCS fabrics while being assured of the best performance, maximum network utilization, and dramatically simplified management.
