Product Overview

The Inventec D5254 is a high performance and programmable ToR and aggregation switch designed for Data centers, large Enterprises as well as Service Provider network deployments. The switch can be deployed in large scale layer 2 and layer 3 networks. Virtualized, overlay and traditional Data center networks are fully supported. Today’s applications require networks to be Agile, Scalable, Flexible, Reliable, Programmable and Open. The D5254 switch presents an open architecture with very high bandwidth and low latency design. It delivers 1.8Tbps throughput in a compact 1RU form factor. It offers 48x25GbE SFP28 ports and 6x100 GbE QSFP28 ports with PHY less design. The SDN switch supports line rate L2/L3 forwarding, programmability, network virtualization, QoS and zero touch provisioning. The D5254 offers customers a compelling choice between a high performance Quad core x86 or a very powerful Octal Core x86 CPUs based on functional and operational requirements.

Support for Open Network Ecosystems

The Inventec D5254 is an open switch that supports multiple Network Operating Systems (NOS). Today the switch ships as bare metal but can be integrated with Inventec SONiC or a third party NOS. The switch is SDN enabled and supports P4. Full ONIE support assures network operators of seamless integration into today’s open network environments.

High Performance, Scalable and Flexible

The Inventec D5254 is a high performance switch allowing wire rate of 2B packets per second with a low cut-through mode latency, 22MB on-chip buffer memory and dynamic buffer management to prevent catastrophic TCP traffic scenarios. The switch offers scalability by supporting choice of high end X86 control processor with upto 16GB of fast DDR4 memory. With a PHY less design, the switch offers a low cut through latency.
The switch is flexible and supports different cabling option as per customer needs. AOC (Active Optical Cabling) and pluggable transceiver optics of different length of fiber connections are supported. The port use is also flexible. Each QSFP28 100GbE port can be used as 4x25 GbE and all SFP2825 GbE ports can be used in 10 GbE mode.
The programmable parser allows for reconfigurability in the field and flexibility to cover broad range of applications.

Agile, Programmable and Supports Analytics

The switch supports programmable parser with Match Action units. This allows for new protocol support. The switch supports RESTful API interface. It allows for automatic provisioning and configuration with Puppet and Chef. Zero touch provisioning is also available. With Openstack orchestration tool integration, the switch enables automation, configuration and provisioning of L2 and L3 services in the data center. Switch also supports in-band Analytics and Telemetry support.

Rich Feature Set

The switch has a rich L2/L3 feature set to address the increase in datacenter network deployments and distributed computing applications. For cloud networking, it includes large L2/L3 switching & forwarding capacity and supports numerous multi-pathing and tunneling technologies and datacenter features like ECMP, VxLAN and NVGRE.
These overlays allow for network agility since the network operators do not have to modify the physical switch devices in case a user VM moves from one rack to another within the datacenter.

Available and Reliable Design

The switch is datacenter optimized with power and fan redundancy. It has a backup SPI boot flash that will activate for boot recovery if primary flash is corrupted. Also, with a Phyless switch, the overall MTBF increases with less number of hardware components.

In Summary

Overall performance, feature-richness, high availability, programmability, port-density, and line-rate switching capability makes the D5254 an excellent choice for next generation large and medium sized datacenters. This also makes the D5254 well suited for use as a general purpose switch in large Enterprises and Service Provider networks.
