DELL 210-39401 Network Switch Networking

Ultra-low-latency, data center optimized
The Dell Networking S-Series S4810 is an ultra-low-latency 10/40GbE top-of-rack (ToR) switch purpose-built for applications in high-performance data center and computing environments. Leveraging a non-blocking, cut-through switching architecture, the S4810 delivers line-rate L2 and L3 forwarding capacity with ultra low latency to maximize network performance. The compact S4810 design provides 48 dual-speed 1/10GbE (SFP+) ports as well as four 40GbE QSFP+ uplinks to conserve valuable rack space and simplify the migration to 40Gbps in the data center core. Priority-based flow control (PFC), data center bridge exchange (DCBX) and enhance transmission selection (ETS), coupled with ultra low latency and line rate throughput, make the S4810 ideally suited for iSCSI storage, FCoE transit and DCB environments. In addition, the S4810 incorporates multiple architectural features that optimize data center network flexibility, efficiency and availability, including I/O panel to PSU airflow or PSU to I/O panel airflow for hot/cold aisle environments, and redundant, hot-swappable power supplies and fans.

The S4810 also supports Dell Networking’s Embedded Open Automation Framework, which provides advanced network automation and virtualization capabilities for virtual data center environments.

An Active Fabric™ design with S4810 switches can be built out to create scalable, high-performance 10/40GbE data center networks. The resiliency of an Active Fabric is superior to legacy, centralized core architectures, since the failure of a single node within a CLOS network cannot bring down the entire switching fabric.

The S4810 is supported with Active Fabric Manager (AFM), which helps automate design and deployment of multi-tier fabrics. AFM helps customers manage multiple fabrics from a single console, enabling a unified view of the entire fabric, when combined with Dell OMNM and other management solutions. With AFM, over 25 templates can be customized for specific workload and deployment scenarios, easily delivering active/active L2 or L3 designs for 1/10/40G with Dell Z Series switches to rack and blade infrastructures (including Dell MXL).

Key applications
