The Dell S4820T top-of-rack (ToR) switch is purpose-built for deployment in high-performance data centre and cloud computing environments, leveraging the popularity of twisted-pair copper cabling and providing the right mix of scalability, performance, operational simplicity and cost-effectiveness.
It is powered by the Force10 operating system (FTOS) and designed to support both Layer 2 and Layer 3 functionality required for Web 2.0, enterprise and cloud services provider data centers.
Key features include:
- 10GBASE-T connectivity – seamless migration from one gigabit to 10 gigabit servers: Especially for customers looking to consolidate server I/O at 10G, Dell enables low-cost copper connectivity between servers and switches, allowing maximum investment protection and cable reuse.
- LAN/SAN convergence: The S4820T is also ideal for customers aiming to consolidate LAN and SAN traffic over a common DCB-enabled 10G switching fabric and is one of the first copper-based 10G switches in the industry to support Fibre Channel over Ethernet (FCoE) using twisted-pair cabling. To that end, the S4820T is being lab tested by leading 10GBASE-T network interface card (NIC) and converged network adapter (CNA) vendors—Broadcom, Emulex, Intel, and QLogic.
- High-performance fabric uplinks: The S4820T is equipped with four 40G uplinks providing for high-speed fabric connectivity enabling scalable multi-rack deployments demanded by larger customers.
Dell MXL 10/40GbE Blade Switch and PowerEdge M I/O Aggregator
Dell Networking continues to experience significant growth in blade switching – with the Dell MXL blade switch and the Dell PowerEdge M I/O Aggregator – reflecting customers’ movement to 10/40G in the data center and more streamlined architectures for server and storage connectivity.
The Dell MXL – powered by FTOS and purpose-built for the Dell PowerEdge M1000e blade server chassis – is a full-featured 1/10/40GbE Layer 2 and Layer 3 blade switch that offers increased bandwidth, scalability, performance and operational simplicity for data center and campus environments. The Dell PowerEdge M I/O Aggregator offers similar connectivity options and is optimized for plug-and-play simplicity and rapid ‘configuration-free’ deployments.
Both products support local switching of server-to-server (east-west) traffic within the PowerEdge 1000e chassis. This enhances network performance as traffic no longer has to travel up to – and back down from – the data center core as other architectures require.
Commercial Availability of OpenFlow in FTOS
Dell also announced the commercial availability of OpenFlow for its FTOS code base. Available now for the Dell Z9000 and S4810 data center switches, OpenFlow is a key technology enabler for next-generation software-defined network (SDN) deployments. The new software is fully compliant with available standards-based OpenFlow controllers, including the Big Switch Controller from Dell partner Big Switch Networks.
The addition of commercially available OpenFlow functionality reinforces Dell’s commitment to software-defined infrastructure. Dell is one of the only vendors to offer a complete and unbiased approach to SDN embracing legacy networking environments, greenfield controller-based deployments as well as hypervisor-oriented architectures.
