Product Overview

The Inventec D7332 is a high-performance network switching device supporting up to 32 x 400GbE, or 64 x 200GbE, or 128 x 100GbE switch ports. It is designed to address performance, capacity and service requirements for next-generation data center and cloud computing environments.

As server interfaces transition to higher Ethernet speeds and virtualization continues to increase link utilization, data center networks are demanding switches with 100GbE and 400GbE connectivity at the edge and aggregation layers.
The D7332 provides scalable, cost effective aggregation, spine and leaf switching for the data center.

The SDN Switch supports line rate L2/L3 forwarding, network virtualization, QoS and zero touch provisioning.

The D7332 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 D7332 is an open switch that supports multiple Network Operating Systems (NOS). Today the switch ships as bare metal but can be integrated with Inventec INOS based on ICOS or SONiC. It can also be integrated with a third party NOS. The switch is SDN enabled. Full ONIE support assures network operators of seamless integration into today’s open network environments.

High Performance, Scalable and Flexible

The Inventec D7332 is a high performance switch allowing wire rate of 8B packets per second with a low cut- through mode latency, 132 MB on-chip buffer memory and dynamic buffer management. The switch offers scalability by supporting choice of high end X86 control processor with up to 32 GB of fast DDR4 memory. With a PHY less design, the switch offers 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 400GbE port can be used as 4x100 GbE, or 2x200 GbE.

The allocated space within the forwarding table is also flexible and can accommodate varying sizes of MAC addresses, Layer 3 host routes and Longest Prefix Match table entries.

Agile, Programmable and Supports Analytics

The switch is programmable and supports RESTful API interface. It allows for automatic provisioning and configuration with Puppet, Chef. Zero touch provisioning is also available. With orchestration tool integration, the switch enables automation and provisioning of L2 and L3 services in the data center. Lots of valuable analytics can be obtained from the switch by using Agent based or In-band Network Telemetry.

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.

Secure, Available and Reliable Design

The switch supports Trusted Platform Module (TPM) with Secure Boot. TPM allows integrity of the switch platform. Along with Secure boot, it allows a chain of trust from power ON till the OS is up and running. 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 PHY less 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 D7332 an excellent choice for next generation large and medium sized datacenters. This also makes the D7332 well suited for use as a campus switch in the Enterprise.
